            <h2>Introduction</h2>


            <p>The EJB 3.0 Object-Relational Mapping Project is a proposed open source project

            
              under the <a href="/technology/">Eclipse Technology Project</a>.</p>

            
            <p>This project proposal is in the <a href="/projects/dev_process/">Proposal

            
              Phase</a> and is posted here to solicit community feedback, additional project

            
              participation, and ways the project can be leveraged from the Eclipse membership-at-large.

            
              You are invited to comment on and/or join the project. Please send all feedback

            
              to the <a

            
            href="/newsportal/thread.php?group=eclipse.technology.ejb-orm">eclipse.technology.ejb-orm</a>

            
              newsgroup. </p>


            <h2>Project Goal</h2>


            <p>The goal of this project is to add comprehensive support to the Eclipse Project

            
              for the definition, editing, and deployment of Object-Relational (O/R) mappings

            
              for EJB 3.0 Entity Beans.  EJB 3.0 O/R mapping support will focus on minimizing

            
              the complexity of mapping by providing creation and automated initial mapping

            
              wizards, and programming assistance such as dynamic problem identification.

            
              The implementation will be extensible so third party vendors can add to its

            
              functionality.</p>

            
              <h2>Project Scope</h2>


            <p>This project will provide tooling to map EJB 3.0 Entity Beans to relational

            
              databases tables, as detailed in <a href="http://www.jcp.org/en/jsr/detail?id=220">JSR

            
              220: Enterprise JavaBeans&#8482; 3.0 Persistence API</a>.  From a J2EE perspective, this tooling

            
              would be an integrated component beside its peers in the JST project under the

            
              larger umbrella of the WTP.  It will leverage the work being done under the

            
              J2EE Core Model and Tools in the areas of J2EE Artifacts and Components and

            
              J2EE Server Tooling.  As EJB 3.0 persistence is also intended to be the persistence

            
              standard for J2SE, it will be necessary for this tooling to support non-J2EE

            
              usage.</p>


            <p>Session and Message Driven Bean configuration is not a part of this project,

            
              as it is expected that the current JST support will be evolved to cover the

            
              changes required by EJB 3.0.  O/R mapping is not applicable to these bean types

            
              and so they are therefore out of scope.</p>

            
            <p> Support for persistence technologies other than JSR 220 (e.g., JSR 222: Java&#8482;

            
              Architecture for XML Binding (JAXB) 2.0) is out of scope.</p>

            
            <p >The goal of the project is the development of tooling and frameworks to support

            
              the construction of EJB 3.0 Entity Beans, not the development of an O/R mapping

            
              framework.   The proposed tools and frameworks are all design time only.  No

            
              runtime libraries or frameworks are included in this proposal.  Runtime support

            
              for EJB 3.0 will be provided by JSR 220 compliant application server implementations.</p>

            
              <p >Extension points will be provided to support vendor extensions to EJB 3.0;

            
                however, while this proposal acknowledges and supports the need for vendor

            
                extensions, the scope of this proposal is limited to the functionality defined

            
                in the EJB 3.0 specification.</p>


            <p>At the time of this writing, the EJB 3.0 specification has not been finalized

            
              and changes are expected before the final draft is issued. Accordingly, the

            
              scope of this proposal will track the draft specification and the tooling will

            
              be validated against the EJB 3.0 reference implementation and available commerial

            
              implementations.</p>

            
              <h2>Project Principles</h2>

            
              <p><b>Leverage the Eclipse Ecosystem</b>:  It is our goal to extend

            
                the Eclipse user experience as well as leverage other Eclipse project functionality

            
                where applicable.</p>

            
              <p><b>Vendor Neutrality</b>: We intend to build an EJB 3.0 tool that is not

            
                biased toward any particular EJB container or persistence vendor.</p>


            <p><b>Extensibility</b>:  It is our intention to provide a generic and extensible

            
              set of editors and frameworks that provide a vendor neutral ability to add proprietary

            
              O/R mapping features that extend the EJB 3.0 specification (e.g., advanced mappings

            
              and querying provided by implementations such as BEA Weblogic, IBM WebSphere,

            
              JBoss Hibernate, and Oracle TopLink).</p>

            
            <p>Extensibility of the EJB 3.0 tooling will not be limited to add-ons extensions.

            
              By being architected as a set of plug-in components, individual components (e.g.,

            
              Entity generation from tables) may be replaced by vendor specific implementations.</p>

            
              <p><b>Incremental Development</b>:  As this project will be subject

            
                to an evolving specification, an agile development process will be employed

            
                to manage and respond to changing requirements.</p>


            <p><strong>Standards Compliance: </strong>The project tooling will be focused

            
              on providing support for persistence Entities as defined by the JSR 220 Enterprise

            
              JavaBeans&#8482; 3.0 specification.</p>

            
            <p><strong>Inclusiveness:</strong> Project participation by all interested parties

            
              is welcome. The initial committers, for example, are from three vendors that

            
              compete agressively in the market but recognize the value of working together

            
              on pre-competitive Eclipse-based tools and technologies.</p>

            
            <h2>Project Description</h2>


            <p>It is now generally accepted that tooling applied in the right scenarios can

            
              increase developer productivity, saving time and money for their organizations.

            
              O/R mapping is one of these scenarios that has benefited from tool support in

            
              the past from providing design time validation of mappings and configuration

            
              to visually managing the mapping of large object models.  Examples of this type

            
              of tool include the <a

            
            href="http://www.oracle.com/technology/products/ias/toplink/mwdemos/index.html">Oracle

            
              TopLink Workbench</a>, <a href="http://www.solarmetric.com/jdo/Kodo_JDO/kododevelopersworkbench.php">Solarmetric's

            
              Kodo Development Workbench</a>, and the <a href="http://www.hibernate.org/Projects/HibernateTools">JBoss

            
              Hibernate Mapping Editor</a>.  IDEs will support annotations, but an O/R mapping

            
              tool should go beyond this to offer further context and intelligence to aid

            
              decision-making and reduce developer errors.</p>


            <p>The specific intent of this project is to fill the current void in lightweight

            
              tooling support for EJB 3.0 persistence.  The project will address this void

            
              with a non-proprietary tooling solution that can be used to map to any EJB 3.0

            
              compliant runtime implementation.  In addition, container and persistence vendors

            
              and open source projects could extend this project with proprietary plug-ins

            
              for their own advanced mapping or configuration support.  While the spec is

            
              in flux, the project would target the reference implementation for EJB 3.0 O/R

            
              Mapping.  See the diagram below for a visual representation.</p>

              <p>As stated above, this project is 100% tooling, and should be completely decoupled

            
                from any particular runtime implementation.  </p>

            <b>Extension Points</b>

            
              <p>The project should be architected as a set of plug-ins, each of which provides

            
                the ability for other groups or vendors to further extend and customize the

            
                functionality in a well-defined manner.  In particular, it is

            
                expected that the core mapping functionality would be extended by:</p>


            <ul>

            
              <li>EJB 3.0 container tools</li>

            
              <li>EJB 3.0 O/R persistence tools</li>

            
            </ul>


            <p>Extension points will be defined to allow tool vendors and open source projects

            
              to extend the core mapping facilities with additional functionality. For example,

            
              extension points would likely be defined for the following areas:</p>


            <ul>

            
              <li>Addition of mapping types</li>

            
              <li>Addition of descriptor types</li>

            
              <li>Extension of descriptor configuration with policies</li>

            
              <li>Addition of query types and configuration</li>

            
              <li>Preferences and other standard extensions</li>

            
            </ul>


            <B>Integration Points with Other Eclipse Projects</B>

            
              <p>Given the scope of the project, the EJB 3.0 O/R mapping tools will interact

            
                with and leverage the following existing Eclipse projects:  </p>

	<h2>Introduction</h2>

	<p>The EJB 3.0 Object-Relational Mapping Project is a proposed open source project
	under the <a href="/technology/">Eclipse Technology Project</a>.</p>
	<p>This project proposal is in the <a href="/projects/dev_process/">Proposal
	Phase</a> and is posted here to solicit community feedback, additional project
	participation, and ways the project can be leveraged from the Eclipse membership-at-large.
	You are invited to comment on and/or join the project. Please send all feedback
	to the <a
	href="/newsportal/thread.php?group=eclipse.technology.ejb-orm">eclipse.technology.ejb-orm</a>
	newsgroup. </p>

	<h2>Project Goal</h2>

	<p>The goal of this project is to add comprehensive support to the Eclipse Project
	for the definition, editing, and deployment of Object-Relational (O/R) mappings
	for EJB 3.0 Entity Beans. EJB 3.0 O/R mapping support will focus on minimizing
	the complexity of mapping by providing creation and automated initial mapping
	wizards, and programming assistance such as dynamic problem identification.
	The implementation will be extensible so third party vendors can add to its
	functionality.</p>
	<h2>Project Scope</h2>

	<p>This project will provide tooling to map EJB 3.0 Entity Beans to relational
	databases tables, as detailed in <a href="http://www.jcp.org/en/jsr/detail?id=220">JSR
	220: Enterprise JavaBeans™ 3.0 Persistence API</a>. From a J2EE perspective, this tooling
	would be an integrated component beside its peers in the JST project under the
	larger umbrella of the WTP. It will leverage the work being done under the
	J2EE Core Model and Tools in the areas of J2EE Artifacts and Components and
	J2EE Server Tooling. As EJB 3.0 persistence is also intended to be the persistence
	standard for J2SE, it will be necessary for this tooling to support non-J2EE
	usage.</p>

	<p>Session and Message Driven Bean configuration is not a part of this project,
	as it is expected that the current JST support will be evolved to cover the
	changes required by EJB 3.0. O/R mapping is not applicable to these bean types
	and so they are therefore out of scope.</p>
	<p> Support for persistence technologies other than JSR 220 (e.g., JSR 222: Java™
	Architecture for XML Binding (JAXB) 2.0) is out of scope.</p>
	<p >The goal of the project is the development of tooling and frameworks to support
	the construction of EJB 3.0 Entity Beans, not the development of an O/R mapping
	framework. The proposed tools and frameworks are all design time only. No
	runtime libraries or frameworks are included in this proposal. Runtime support
	for EJB 3.0 will be provided by JSR 220 compliant application server implementations.</p>
	<p >Extension points will be provided to support vendor extensions to EJB 3.0;
	however, while this proposal acknowledges and supports the need for vendor
	extensions, the scope of this proposal is limited to the functionality defined
	in the EJB 3.0 specification.</p>

	<p>At the time of this writing, the EJB 3.0 specification has not been finalized
	and changes are expected before the final draft is issued. Accordingly, the
	scope of this proposal will track the draft specification and the tooling will
	be validated against the EJB 3.0 reference implementation and available commerial
	implementations.</p>
	<h2>Project Principles</h2>
	<p><b>Leverage the Eclipse Ecosystem</b>: It is our goal to extend
	the Eclipse user experience as well as leverage other Eclipse project functionality
	where applicable.</p>
	<p><b>Vendor Neutrality</b>: We intend to build an EJB 3.0 tool that is not
	biased toward any particular EJB container or persistence vendor.</p>

	<p><b>Extensibility</b>: It is our intention to provide a generic and extensible
	set of editors and frameworks that provide a vendor neutral ability to add proprietary
	O/R mapping features that extend the EJB 3.0 specification (e.g., advanced mappings
	and querying provided by implementations such as BEA Weblogic, IBM WebSphere,
	JBoss Hibernate, and Oracle TopLink).</p>
	<p>Extensibility of the EJB 3.0 tooling will not be limited to add-ons extensions.
	By being architected as a set of plug-in components, individual components (e.g.,
	Entity generation from tables) may be replaced by vendor specific implementations.</p>
	<p><b>Incremental Development</b>: As this project will be subject
	to an evolving specification, an agile development process will be employed
	to manage and respond to changing requirements.</p>

	<p><strong>Standards Compliance: </strong>The project tooling will be focused
	on providing support for persistence Entities as defined by the JSR 220 Enterprise
	JavaBeans™ 3.0 specification.</p>
	<p><strong>Inclusiveness:</strong> Project participation by all interested parties
	is welcome. The initial committers, for example, are from three vendors that
	compete agressively in the market but recognize the value of working together
	on pre-competitive Eclipse-based tools and technologies.</p>
	<h2>Project Description</h2>

	<p>It is now generally accepted that tooling applied in the right scenarios can
	increase developer productivity, saving time and money for their organizations.
	O/R mapping is one of these scenarios that has benefited from tool support in
	the past from providing design time validation of mappings and configuration
	to visually managing the mapping of large object models. Examples of this type
	of tool include the <a
	href="http://www.oracle.com/technology/products/ias/toplink/mwdemos/index.html">Oracle
	TopLink Workbench</a>, <a href="http://www.solarmetric.com/jdo/Kodo_JDO/kododevelopersworkbench.php">Solarmetric's
	Kodo Development Workbench</a>, and the <a href="http://www.hibernate.org/Projects/HibernateTools">JBoss
	Hibernate Mapping Editor</a>. IDEs will support annotations, but an O/R mapping
	tool should go beyond this to offer further context and intelligence to aid
	decision-making and reduce developer errors.</p>

	<p>The specific intent of this project is to fill the current void in lightweight
	tooling support for EJB 3.0 persistence. The project will address this void
	with a non-proprietary tooling solution that can be used to map to any EJB 3.0
	compliant runtime implementation. In addition, container and persistence vendors
	and open source projects could extend this project with proprietary plug-ins
	for their own advanced mapping or configuration support. While the spec is
	in flux, the project would target the reference implementation for EJB 3.0 O/R
	Mapping. See the diagram below for a visual representation.</p>
	<p align=center> <img border=0 width=568 height=357
	src="images/EJB30ToolingDiagram.jpg"
	v:shapes="_x0000_i1025"> </p>
	<p>As stated above, this project is 100% tooling, and should be completely decoupled
	from any particular runtime implementation. </p>
	<p>Below are areas of targeted support for the project:</p>
	<B>EJB Specific Functionality</B>

	<p>This section illustrates the type of mapping support intended, but is not meant
	to be a comprehensive list of supported functionality.</p>
	<ul>
	<li>Basic mapping (field/column) and relationship (foreign key) mapping support</li>
	<li>Embeddable Classes</li>
	<li> Entity Bean Inheritance</li>
	<li>Entity Manager (Query API Support)
	<ul>
	<li>Named Queries</li>
	<li>EJBQL Queries</li>
	<li>Native Queries</li>
	</ul>
	</li>
	<li>Entity Bean Lifecycle management
	<ul>
	<li>Callback and EntityListener configuration</li>
	</ul>
	</li>
	<li>Version Locking</li>
	<li>ID Generators</li>
	<li>Multi-table mapping </li>
	<li>LOB mappings</li>
	<li>Reading and writing of EJB 3.0 O/R Annotations</li>
	<li> Reading and writing of EJB 3.0 O/R XML Descriptors</li>
	<li>Creation and editing of persistence archives (.par).</li>
	<li>Creation and editing of persistence.xml files.</li>
	</ul>
	<B>Automation/Generation Functionality</B>
	<p>Wizards will be provided to assist in prototyping and jump starting of projects.
	Features like automated initial mapping of classes to tables based on syntactic
	name similarity remove much of the basic work associated with O/R mapping.</p>

	<ul>
	<li>Automated initial mapping process for basic mappings, relationship mappings,
	and inheritance</li>
	<li>Generation of Entity Beans from table definitions</li>
	<li>Generation of table definitions from Entity Beans</li>
	</ul>
	<B>Additional Functionality</B>
	<p>Developer productivity will be enhanced with the following features.</p>

	<ul>
	<li>Coding assistance for annotation parameters (e.g., valid table/column names)</li>
	<li>Mapping assistance and validation through dynamic problem reporting</li>
	<li>Ability to define and manage persistence needs of large projects</li>
	<li>Visual EJBQL Builder</li>
	<li>Ability to keep EJBQL queries in sync with Java class definitions in the
	face of refactoring</li>
	</ul>

	<b>Extension Points</b>
	<p>The project should be architected as a set of plug-ins, each of which provides
	the ability for other groups or vendors to further extend and customize the
	functionality in a well-defined manner. In particular, it is
	expected that the core mapping functionality would be extended by:</p>

	<ul>
	<li>EJB 3.0 container tools</li>
	<li>EJB 3.0 O/R persistence tools</li>
	</ul>


	<p>Extension points will be defined to allow tool vendors and open source projects
	to extend the core mapping facilities with additional functionality. For example,
	extension points would likely be defined for the following areas:</p>

	<ul>
	<li>Addition of mapping types</li>
	<li>Addition of descriptor types</li>
	<li>Extension of descriptor configuration with policies</li>
	<li>Addition of query types and configuration</li>
	<li>Preferences and other standard extensions</li>
	</ul>

	<B>Integration Points with Other Eclipse Projects</B>
	<p>Given the scope of the project, the EJB 3.0 O/R mapping tools will interact
	with and leverage the following existing Eclipse projects: </p>

	<ul>
	<li><a href="/jdt/index.html">JDT (Java Development Tools)
	Core, UI, and LTK (Language ToolKit)</a>
	<ul>
	<li>Java class metadata</li>
