 <div id="taskbody"><div id="shortdesc">This topic explains how to add a facet
 to an existing project in your workspace.</div>

 <div class="section" id="context"><anchor id="topictop"></anchor><p>New projects
 generally have facets added to them when they are created. To add another
 facet to a project that already exists, follow these steps:</p>
 </div>

 <ol id="steps">
 <li class="stepexpand"><span>In the Project Explorer view, right-click the project and then
 click <span class="uicontrol">Properties</span>.</span></li>

 <li class="stepexpand"><span>In the Properties window, click <span class="uicontrol">Project Facets</span>.</span>
  The Project Facets page lists the facets in the project.
 </li>

 <li class="stepexpand"><span>Click <span class="uicontrol">Add/Remove Project Facets</span>.</span></li>

 <li class="stepexpand"><span>In the Add/Remove Project Facets window, select the check boxes
 next to the facets you want this project to have.</span> <div class="p">Only the facets
 that are valid for the project are listed:<ul>
 <li>The list of runtimes selected for the project limits the facets shown
 in the list. Only the facets compatible with all selected target runtimes
 are shown.</li>

 <li>The currently selected facets and their version numbers limit the other
 facets shown in the list. For example, if the project contains the Dynamic
 Web Module facet, the EJB Module facet is not listed because these two facets
 cannot be in the same project.</li>

 </ul>
 You can find out more about the requirements and limitations for each
 facet by right-clicking the facet name and then clicking <span class="uicontrol">Show Constraints</span>.</div>
 <p>You
 can also choose a preset combination of facets from the <span class="uicontrol">Presets</span> list.</p>

 </li>

 <li class="stepexpand"><span>Choose a version number for the facet by clicking the current version
 number and selecting the version number you want from the drop-down list.</span>
 </li>

 <li class="stepexpand"><span>To remove a facet, clear its check box.</span> Not all facets
 can be removed.</li>

 <li class="stepexpand"><span>If you want to limit the project so it will be compatible with
 one or more runtimes, click the <span class="uicontrol">Show Runtimes</span> button
 and select the runtimes that you want the project to be compatible with.</span>
  For more information on runtimes, see <a href="tjtargetserver.html" title="When you develop J2EE applications,&#10;you can specify the server runtime environments for your J2EE projects. The&#10;target server is specified during project creation and import, and it can&#10;be changed in the project properties.
