<prereq><p>A web fragment is a logical partitioning of the web application
in such a way that the frameworks being used within the web application
can define all the artifacts without requiring you to edit or add
information in the web.xml. It can include almost all the same elements
that the web.xml descriptor uses, with these requirements:</p><ul>
<li>The top level element for the descriptor must be web-fragment</li>
<li>The corresponding descriptor file must be called web-fragment.xml</li>
</ul><p>If a framework is packaged as a jar file and has metadata
information in the form of deployment descriptor, then the web-fragment.xml
descriptor must be in the META-INF/ directory of the jar file.</p><p>A
web fragment is a mechanism for either defining or extending the deployment
descriptor of a web application by means of pluggable library jars
that contain both the incremental deployment information (in the web-fragment.xml)
and potentially any related or relevant classes.  The web fragment
is also packaged as a library (jar), with the web-fragment.xml in
the META-INF directory. Consequently, the web fragment project is
essentially a Utility project, with the addition of a web fragment
facet to it. The web fragment facet enables you to add relevant context-sensitive
functionality to the fragment project.</p></prereq>

<step><cmd>In the <tm tmtype="tm" trademark="Java">Java</tm> EE perspective,
select <menucascade><uicontrol>File</uicontrol><uicontrol>New</uicontrol>
<uicontrol>Web Fragment Project</uicontrol></menucascade>. Alternatively,
right-click the Enterprise Explorer context menu, and select <menucascade>
<uicontrol>New</uicontrol><uicontrol>Web Fragment Project</uicontrol>
</menucascade>. The Web fragment wizard opens.</cmd></step>
<step><cmd>In the <uicontrol>Name</uicontrol> field, type a name for
the Web fragment project. To change the default <uicontrol>Project
contents</uicontrol>, click the <uicontrol>Browse</uicontrol> button
to select a new location.</cmd><info><p>If you specify a non-default
project location that is already being used by another project, the
project creation fails.</p></info></step>
<step><cmd>The <uicontrol>Target runtime</uicontrol> field is pre-populated
with the selection from the enterprise project.</cmd></step>
<step importance="optional"><cmd>Select a pre-defined project configuration
from the <uicontrol>Configurations</uicontrol> drop-down list.</cmd>
</step>
<step importance="optional"><cmd>If you want to modify the configuration
details, click <uicontrol>modify</uicontrol>:</cmd></step>
<step importance="optional"><cmd>Select one or more project facets
from the <uicontrol>Project Facets</uicontrol> list. To specify server
runtime environments, click <uicontrol>Show Runtimes</uicontrol> and
select one or more runtimes. After making your selections, you can
save your custom configuration by clicking <uicontrol>Save</uicontrol>.</cmd>
</step>
<step importance="optional"><cmd>Select the <uicontrol>Add project
to Dynamic Web project</uicontrol> check box to add the new module
to an enterprise module (WAR) project.</cmd><info>Type a new project
name or select an existing enterprise module project from the drop-down
list in the <uicontrol>Dynamic Web project name</uicontrol> combination
box. Or, click <uicontrol>New</uicontrol> to launch the New EAR module
Project wizard.</info></step>
<step><cmd>Select <uicontrol>Add project to working sets</uicontrol> to
add the Web fragment project to an existing working set, or click <uicontrol>Select</uicontrol> to
locate a working set, and click <uicontrol>Next</uicontrol>.</cmd>
</step>
<step><cmd>On the Configure project for building a <tm tmtype="tm"
trademark="Java">Java</tm> application page, on the <uicontrol>Source
folders on build path</uicontrol> field, click <uicontrol>Add Folder...</uicontrol> to
add folders for your source on the build path, or accept the default
value (src).</cmd></step>
<step><cmd>In the <uicontrol>Default output Folder:</uicontrol> field,
specify a folder for your output files or accept the default value
(bin), and click <uicontrol>Finish</uicontrol>.</cmd></step>
