<h2> Introduction </h2> | |
<p>The JWT project is a proposed open source project under the Eclipse Technology Project. | |
</p><p>This proposal is in the Project Proposal Phase (as defined in | |
the Eclipse Development Process document) and is written to declare its | |
intent and scope. It is written to solicit additional participation and | |
input from the Eclipse community. You are invited to comment on and/or | |
join the project. Please send all feedback to the <b>eclipse.technology.jwt</b> newsgroup. The project wiki is available at <a href="http://wiki.eclipse.org/index.php/Java_Workflow_Toolbox_Project" class="external free" title="http://wiki.eclipse.org/index.php/Java Workflow Toolbox Project" rel="nofollow">http://wiki.eclipse.org/index.php/Java_Workflow_Toolbox_Project</a> . | |
</p><p><br> | |
</p> | |
<h2> Overview </h2> | |
<p>The JWT project aims to provide both <b>build-time and runtime generic tools for workflow engines</b>. | |
It will initially be composed of two tools, WE (Workflow Editor) and | |
WAM (Workflow engine Administration and Monitoring tool). JWT also aims | |
to provide generic APIs for defining and administrating business | |
processes, in order to achieve said genericity. | |
</p><p><b>WE (Workflow Editor)</b> will be a visual tool for creating, | |
managing and reviewing process definitions. Straightforward and simple, | |
WE will let users quickly create workflow process definitions, check | |
and store them for further use. Once a process definition is proved | |
valid, it can be imported/referenced into new ones, thus shortening the | |
time and effort needed to define the workflow process. WE provides | |
several views: for business managers to change the control flow of a | |
process, for technical experts to invoke services, or others. | |
</p><p><b>WAM (Workflow engine Administration and Monitoring tool)</b> | |
will be used to deploy and test a workflow in a workflow engine so to | |
handle an engine's process definition external repository, to load some | |
process definitions into a specific Workflow Engine, unload it, update | |
it, instantiate it, monitor the Workflow Engines processes, perform | |
mappings among participant definitions and real users, and among | |
application definitions and tool agents. | |
</p><p><br> | |
</p> | |
<h2> Background </h2> | |
<h3> State of the commercial BPM tooling market </h3> | |
<p>Companies typically loose productivity and effort because of their | |
IT system being inefficient or not adapted to the existing and | |
reality-grounded business processes. Since companies want to get | |
increased control over their IT systems, they adapt them to their | |
business needs rather than the opposite. This is sometimes called | |
"business driven development" or "top-down approach". | |
</p><p>Some major ISVs such as WebMethods, SeeBeyond and others | |
propose a complete galaxy of development and runtime tools that enable | |
this strategy. These tools allow a company to simply define its | |
business processes and map the different activities of the processes to | |
existing technical services or applications. Therefore such tools - and | |
indeed such a strategy - obviously resonate with integration | |
problematics. | |
</p><p>However, they have limitations. First, these proprietary tools | |
only have one graphical representation and generate one output format. | |
Second, they can only interact with one specific workflow engine. | |
Third, the fact that these tools are proprietary, closed source | |
projects implies that the diffusion and adoption of the technology is | |
very limited and the benefits of the business driven development are | |
still largely unappreciated. | |
</p> | |
<h3> Evolution of BPM in light of the new information system architecture and integration standards </h3> | |
<p>The arrival of new standards like the JSR 208 (the Java Business | |
Integration, JBI), SDO (Service Data Objects) or SCA (Service Component | |
Architecture) not only means that existing products will change again, | |
but that the time is right for opening up the field and welcome such a | |
new, generic framework that is adaptable to any specific requirements. | |
</p><p>The <i>Java Business Integration (JBI)</i> specification | |
proposes a standard solution to integration problems for Enterprise | |
Service Buses (ESB). In such a service platform, the orchestration | |
services are critical proponents in allowing discrete messages to be | |
routed in the context of the global business process. Business process | |
engines providing such orchestration services are already being | |
integrated in JBI solutions (as shown by open source ESBs like Apache | |
ServiceMix or Objectweb Petals), in a way that is hence bound to be | |
increasingly standardized and tightly linked to run-time and even | |
build-time tools. | |
</p><p>On the other side, the <i>SCA specification</i> builds on the | |
SOA philosophy so as to describe a model for assembling composite | |
applications, and therefore encompasses a set of steps that are | |
required in order to deploy most of SOA-style information system | |
architectures. There is a natural complementarity between the | |
SCA-specified architectural model and the vision of information | |
system-wide business dynamics enabled by BPM, and that is exemplified | |
in top-level tooling platforms that, like Eclipse STP or the recent | |
SCOrWare proposal made by several Objectweb members (including INRIA, | |
Amadeus, Open Wide), aim at easing the development and deployment of | |
SOA and SCA architectures. That's why both SOA models and tooling | |
platforms will concur to better and more standardized BPM tooling. | |
</p> | |
<h3> What JWT proposes </h3> | |
<p>The goal of the JWT project is to develop a set of tools that help | |
to develop, deploy and test workflows. JWT is not just another modeling | |
tool and workflow engine, but provides an adaptable framework for | |
different graphical representations and XML notations, as well as | |
different workflow engines. | |
</p><p>The JWT tooling suite is a natural member of top-level tooling | |
platforms that, like Eclipse STP, can be used to ease development | |
targeting integration platforms such as ESBs. Both single users and | |
ISVs can use such set of tools either for direct use or for building a | |
complete development software stack for their integration platform. In | |
such light, one of the natural goals of JWT is good integration with | |
the Eclipse STP platform. | |
</p><p><br> | |
</p> | |
<h2> Description </h2> | |
<h3> Workflow Editor (WE) </h3> | |
<p>WE will be a tool for the modeling of process definitions. The final | |
output of this process modeling phase is an XML file which can be | |
interpreted at runtime by any workflow engine compliant with the XML | |
format of the process definition. WE will provide four core | |
features : | |
</p> | |
<ul><li> Different graphical representations of the process definition | |
</li></ul> | |
<ul><li> Export of process definitions to several XML-formats | |
</li></ul> | |
<ul><li> Import of valid XML process definition and its graphical | |
representations: process can be defined in several formats (mostly | |
based on XMI) and the graphical figures can be described in an abstract | |
way. | |
</li></ul> | |
<ul><li> Additional features easing the development of business | |
processes, like business process validation, business process reuse (in | |
conjunction with the WAM's Process Repository) and semantic matching. | |
Partners of JWT are currently working on several semantic process | |
matching algorithms and procedures which will be included in WE. | |
</li></ul> | |
<p><br> | |
WE can be subdivided into two different layers : | |
</p> | |
<ul><li> <b>the graphical representation layer</b>. The intent behind | |
this is to be able to plug in several views for the same workflow | |
definition file: for example, a business manager might want to see | |
other details than an IT expert. Additionally it might be necessary to | |
have one view for the certification of ISO 9000, one for ITIL, and | |
others. Having several pluggable graphic representation will allow us | |
to expose simplified, business oriented user-friendly views of the same | |
workflow definition. Note that Amadeus will contribute on the | |
extensibility mechanism allowing business-specific activities and | |
integrate business specific representation views in the scope of the | |
SCOrWare project. | |
</li></ul> | |
<ul><li> <b>the grammar definition layer</b>. The intent behind this is | |
to be able to plug in several different grammars for the same | |
representation: this is of particular interest when a graphical | |
representation (such as BPMN or UML) can support different grammars. | |
For example, BPMN can support both XPDL and BPEL. WE will be able to | |
support not only XPDL and BPEL but other proprietary notations (e.g. | |
jPDL from JBoss jBPM) or future standards as well. | |
</li></ul> | |
<p>As process definitions and graphical representations can vary, we | |
propose to build a generic, extendable framework that enables several | |
representations and grammars to be implemented and plugged in, thanks | |
to a common, pivotal business process definition metamodel. The list of | |
generatable process definitions as well as viewable graphical | |
representation will be extensible. | |
</p> | |
<h3> Workflow engine Administration and Monitoring tool (WAM) </h3> | |
<p>The WAM aims to provide tooling for managing business processes | |
independently of the underlying workflow engine. In order to achieve | |
that, the WAM will rely on a generic workflow engine administration | |
API, whose definition is at the heart of the project. | |
</p><p>Building on this API, the WAM intends to implement the following functionalities : | |
</p><p><b>Process definition management :</b> | |
</p> | |
<ul><li> Repository Management : The repository management | |
displays all available files in the engines package repository. This is | |
the place where you can manage the repository of the engine. You can | |
upload a new package file from your local machine into the repository | |
or delete one from the it. | |
</li></ul> | |
<ul><li> Package Management : The package management displays all | |
packages that are loaded into the engine. It enables you to load and | |
unload packages to/from engine, as well as to update some already | |
loaded packages. | |
</li></ul> | |
<p><b>Process execution management :</b> | |
</p> | |
<ul><li> Process Instantiation Management : Lets you view the | |
package-process definition tree of the loaded packages. The graphical | |
workflow representation will be used to show the state of execution of | |
the instantiated process. | |
</li></ul> | |
<ul><li> Process Monitor : Lets you manage process instances like suspend, stop, view process or activities. | |
</li></ul> | |
<p><b>Process runtime resources mapping :</b> | |
</p> | |
<ul><li> User Management : Lets you manage the users of the | |
process engine by defining new ones, deleting existing ones or changing | |
their properties. | |
</li></ul> | |
<ul><li> Application Mapping : Lets you map a package and its | |
process applications to the real applications handled by a tool agent. | |
</li></ul> | |
<p><b>User-oriented process management :</b> | |
</p> | |
<ul><li> Worklist Management : Lets you perform the work items of | |
the instantiated processes. As an admin user, you can perform your work | |
items, and you can see work items from others. Also, you have a | |
possibility to re-assign the work item from one user to another. | |
</li></ul> | |
<ul><li> "Desktop Business Process" tooling : this is more of a | |
simple, generic use case implementation allowing standalone, | |
desktop-integrated business processes for common end user tasks such as | |
flight booking. Its aim is to provide a ready-to use application out of | |
the box and to open up the BPM field to end user needs. | |
</li></ul> | |
<p><br> | |
Fulfilling these requirements will be achieved by : | |
</p> | |
<ul><li> Defining a simple, but extensible API for each of the | |
requirements topics, as said before. These APIs will allow vendors to | |
make their own implementation to get their workflow engine managable. | |
JWT will provide default or stub implementations for them, allowing | |
progressive integration of a workflow engine model in the WAM. A | |
generic API to start and stop a workflow engine is the most critical of | |
them, and will be the first step to achieve for the WAM. | |
</li></ul> | |
<ul><li> Defining specific workflow engine models, in a similar | |
approach to the one used for J2EE server model in the JST project. | |
These workflow engine models could then be used by end users to define | |
their own engine in their own specific environment. As soon as a | |
workflow engine has been defined by a user, it would be possible to | |
deploy a process definition to this engine. JWT will provide such a | |
model for a specific workflow engine (which will have to be chosen, but | |
will probably be XPDL compliant). | |
</li></ul> | |
<h3> Use cases and demonstrators </h3> | |
<p>As said above, these comprise : | |
</p> | |
<ul><li> Dedicated views for business-specific use cases | |
</li></ul> | |
<ul><li> "Desktop Business Process" standalone applications | |
</li></ul> | |
<ul><li> Various other contributions foreseen by JWT partners | |
</li></ul> | |
<p><br> | |
</p> | |
<h2> Architecture </h2> | |
<p>JWT's architecture will be based on an MDA approach and will address | |
the several business-specific extensions problematics through the DSL | |
paradigm. The Eclipse framework and libraries will be used in order to | |
provide the required tools. Note that additionnally, Obeo SA (the | |
creator of the Open Source DSL platform Acceleo) will contribute its | |
MDA / DSL expertise to JWT. | |
</p><p>Here are some elements furthering and depicting what has been outlined above : | |
</p> | |
<h3> WE Architecture </h3> | |
<p>The WE will allow to plug any process XML-based grammar in the JWT | |
Workflow Model framework and display its graphical representation. | |
</p><p>The principles of mapping processes to representations will be | |
based on the Workflow-Model API. This API will identify commonly used | |
entities within a workflow definition model, their relationships and | |
attributes following their XML grammar and map them to a common, | |
pivotal process definition metamodel. This workflow model will be our | |
pivot model which supports all other views. | |
</p><p>As a starting point JWT will provide support only for a single | |
grammar and a single representation. Their choice have to be validated, | |
but BPMN and XPDL are strong candidates. | |
</p><p>The WE architecture is shown in the following picture : | |
</p><p> | |
<center> | |
<a href="./Jwt_we_architecture.png" class="image" title="Image:Jwt_we_architecture.png"><img src="./Jwt_we_architecture.png" alt="Image:Jwt_we_architecture.png" longdesc="/index.php/Image:Jwt_we_architecture.png" height="398" width="578"></a> | |
</center> | |
</p> | |
<h3> WAM Architecture </h3> | |
<p>The WAM aims to manage the definition process into a workflow | |
engine. In order to be workflow-engine agnostic, it will allow to | |
define a workflow engine based on a workflow engine model. | |
</p><p>This JWT workflow engine model will be first developed as an | |
extension of the basic start / stop / deploy API over BPM engines used | |
in WAM towards a meta-model for the easy adoptation of new server types | |
allowing more extensive server management features. | |
</p><p>As a starting point JWT will provide support only for a single | |
workflow engine. Its choice will have to be consistent with the | |
available WE grammar implementation. | |
</p><p>The WAM architecture is shown in the following picture : | |
</p><p> | |
<center> | |
<a href="./Jwt_wam_architecture.png" class="image" title="Image:Jwt_wam_architecture.png"><img src="./Jwt_wam_architecture.png" alt="Image:Jwt_wam_architecture.png" longdesc="/index.php/Image:Jwt_wam_architecture.png" height="482" width="674"></a> | |
</center> | |
</p><p><br/></p> | |
<h2> Extension points </h2> | |
<p>The strategy to build the JWT project features will be "divide and | |
conquer". Things will be split as much as possible into separate | |
working groups and plugins in order to parallelize work, boost | |
development and provide the ability for other groups or vendors to | |
further extend and customize the functionality in a well-defined | |
manner. | |
</p><p>In WE as well as between WE and WAM, there will be an | |
architectural decoupling. WE and WAM will, at least, be two separate | |
plugins, but presumably it will take the form of this list of plugins: | |
</p> | |
<h3> For the WE </h3> | |
<ul><li> Workflow graphical representation | |
</li></ul> | |
<ul><li> Workflow grammar definition | |
</li></ul> | |
<p><br> | |
Concretely, the WE will take the form of a MultiPageEditor(Workflow Editor) and a wizard composed of : | |
</p> | |
<ul><li> Graph view : composed of two graphical viewers. It allows to graphically model processes and activities | |
</li></ul> | |
<ul><li> Source view : represents the XML file which it the result of graphical edition. | |
</li></ul> | |
<ul><li> Outline view : gives an overview of process' activities. | |
</li></ul> | |
<ul><li> Attribute view : based on property view, used to edit entities attributes. | |
</li></ul> | |
<ul><li> Entities Property view : based on property view, used to edit the entities properties. | |
</li></ul> | |
<h3> For the WAM </h3> | |
<ul><li> Workflow engine model | |
</li></ul> | |
<ul><li> Workflow monitoring tool : | |
<ul><li> Repository Management | |
</li><li> Package Management | |
</li><li> Process Instantiation Management | |
</li><li> Process Monitor | |
</li><li> User Management | |
</li><li> Application Mapping | |
</li><li> Worklist Management | |
</li></ul> | |
</li></ul> | |
<p><br> | |
Thus concretely, the WAM plugin will be composed of : | |
</p> | |
<ul><li> A workflow engine model in the run menu and the launcher | |
</li></ul> | |
<ul><li> The graph view of WE for displaying the state of process instances | |
</li></ul> | |
<ul><li> Several views to represent worklist, user management, process | |
instanciation management, application mapping, repository management. | |
These views will have to be defined in detail in the scope of the | |
project. | |
</li></ul> | |
<h3> Integration Points with Other Eclipse Projects </h3> | |
<p>Given the scope of the project, the JWT project will interact with and leverage the following existing Eclipse projects: | |
</p> | |
<ul><li> WST (Web Standard Tools) | |
</li></ul> | |
<ul><li> GEF (Graphical Editing Framework) | |
</li></ul> | |
<ul><li> EMF (Eclipse Modeling Framework) | |
</li></ul> | |
<ul><li> GMF (Graphical Modeling Framework) | |
</li></ul> | |
<ul><li> STP (SOA Tools platform) has been created at the end of 2005 | |
to provide tooling around the Service Oriented Architecture paradigm, | |
according to the SCA (Service Component Architecture) specification. | |
Therefore JWT's integration with STP is important. Along its primary | |
founders (Iona, IBM, Sybase and BEA), Objectweb is involved as a member | |
of the Project Management Committee, and through the involvement in STP | |
the work at JWT and STP can be aligned easily. Moreover, JWT has been | |
recognized as a natural friend project of BPM-themed STP subprojects, | |
such as STP BPEL and STP BPMN, with whom collaboration will be as | |
thorough as possible. Note that putting JWT's priorities initially on | |
the XPDL grammar and business-level activity representation would make | |
JWT a natural complement to the existing BPMN and BPEL projects, while | |
not precluding any further collaboration. | |
<br>(Contact has been made with the BPMN project as a starting | |
point for further collaboration, which may include code or feature | |
integration in either way.) | |
</li></ul> | |
<ul><li> Validation frameworks (like the EMF Validation Framework or Recipe from GTM/OAW) | |
</li></ul> | |
<ul><li> Callisto / Europa | |
</li></ul> | |
<p><br> | |
Additionally JWT will have impact on project which are not hosted by Eclipse, e.g. | |
</p> | |
<ul><li> The Petals Objectweb ESB solution, which is the outcome of the JoNES project | |
</li></ul> | |
<ul><li> The recently approved SCorWare proposal, which gathers several | |
Objectweb members (including INRIA, Amadeus, Open Wide) aims to build | |
an SOA development and deployment platform on top of other ObjectWeb | |
projects. | |
</li></ul> | |
<p><br/></p> | |
<h2> Organization </h2> | |
<p>The life cycle of this project may be similar to the Equinox | |
project. That is, once this work matures, it may be incorporated into | |
the Eclipse Platform to provide a common open source substrate that | |
industrial/commercial users could use to build solutions. | |
Alternatively, it may continue as a Technology subproject. | |
</p> | |
<h3> Sponsoring Organizations </h3> | |
<ul><li> ObjectWeb is an international consortium fostering the | |
development of open-source middleware for enterprise applications: ESB, | |
EAI, e-business, clustering, grid computing, managed services and more. | |
</li></ul> | |
<ul><li> SCOrWare is a recently approved project funded by european | |
research public funds that aims to develop an SOA development and | |
deployment platform. Its members include INRIA, Amadeus, Open Wide, | |
Obeo, INT Evry. The SCOrWare-produced BPM tooling (comprising business | |
process orchestration, semantic process matching, business use cases | |
and an MDA / DSL approach) will be contributed and integrated in JWT. | |
</li></ul> | |
<ul><li> Open Wide is a French company created in 2001 providing | |
services around open source components and a national leader in the | |
entreprise portal integration field. Open Wide's developers are | |
contributing to if not leading some open source projects such as RTAI | |
or GForge. Open Wide has developed one of the first integration | |
platform entirely based on open source components and called NoSICA. It | |
is also part of the ObjectWeb's ESB initiative, of ObjectWeb's | |
distributed, JBI based, ESB framework called Petals / JOnES and of | |
Objectweb's forthcoming SCOrWare SCA platform. | |
</li></ul> | |
<ul><li> The Programming Distributed Systems Lab of the University of | |
Augsburg, Germany, is researching in the focus on software engineering in general | |
and more detailed in the model-driven software development related to | |
distributed systems. Their core competences are on software | |
engineering, interoperability and software automation in the field of | |
business process modeling, autonomic computing and semantics. | |

<h3> Initial Roadmap </h3> | |
<p>The initial roadmap of JWT mirrors its first objectives of | |
</p> | |
<ol><li> having "something that works", an advanced proof of concept | |
that actually achieves cross-grammar and cross-representation | |
integration. That means it will benefit from having a release-oriented | |
development process, different teams working in parallel on supporting | |
each format, and integrating existing contributions. | |
</li><li>laying the groundwork to a generic workflow edition API | |
in the previous process. Being as much as possible open about other BPM | |
format implementation and also other BPM tooling projects will be | |
critical. The board will help in keeping in touch with key people in | |
this context. | |
</li></ol> | |
<p>The following roadmap takes into account the fact that we will use | |
as much as possible existing code and contributions in order to provide | |
our features, in order to boost both of these objectives. This task | |
list is not exhaustive in any way, and rather describes a minimal set | |
of what is needed to </p> | |
<ul><li> Prerequisite : decision process on the model | |
</li></ul> | |
<ul><li> Decision process on languages (includes studies and proof of concept) and engines | |
</li></ul> | |
<ul><li> WE : Making the model flexible. This comprises singleing | |
out extension points in it for grammars, representation views and their | |
business-specific extensions. | |
</li></ul> | |
<ul><li> WE : Doing or integrating an actual implementation over a chosen grammar language | |
</li></ul> | |
<ul><li> WE : Doing or integrating an actual implementation for a chosen representation language | |
</li></ul> | |
<ul><li> WE 1.0 release packaging - aiming at March 2007 | |
</li></ul> | |
<ul><li> WAM : further decision process in order to chose a prefered engine (includes proof of concept) | |
</li></ul> | |
