| <p id="cfacets__aboutfacet"><a name="cfacets__aboutfacet"><!-- --></a>When you add a facet to a project, that project is configured |
| to perform a certain task, fulfill certain requirements, or have certain characteristics. |
| For example, the EAR facet sets up a project to function as an enterprise |
| application by adding a deployment descriptor and setting up the project's |
| classpath.</p> |
| |
| <p>You can add facets only to J2EE projects and other types of projects that |
| are based on J2EE projects, such as enterprise application projects, dynamic |
| Web projects, and EJB projects. You cannot add facets to a Java™ project |
| or plug-in project, for example. Typically, a facet-enabled project has at |
| least one facet when it is created, allowing you to add more facets if necessary. |
| For example, a new EJB project has the EJB Module facet. You can then add |
| other facets to this project like the EJBDoclet (XDoclet) facet. To add a |
| facet to a project, see <a href="taddingfacet.html" title="This topic explains how to add a facet to an existing project in your workspace.">Adding a facet to a J2EE project</a>.</p> |
| |
| <p>Some facets require other facets as prerequisites. Other facets cannot |
| be in the same project together. For example, you cannot add the Dynamic Web |
| Module facet to an EJB project because the EJB project already has the EJB |
| Module facet. Some facets can be removed from a project and others cannot.</p> |
| |
| <p>Facets also have version numbers. You can change the version numbers of |
| facets as long as you stay within the requirements for the facets. To change |
| the version number of a facet, see <a href="tchangefacet.html" title="You can change the version of a facet in a J2EE project by editing the facets for the project.">Changing the version of a facet</a>.</p> |
