| * The <code>org.netbeans.modules.j2ee.api/ejbjar</code> module registers an |
| * implementation of this interface to global lookup which looks for the |
| * project which owns a file (if any) and checks its lookup for this interface, |
| * and if it finds an instance, delegates to it. Therefore it is not normally |
| * necessary for a project type provider to register its own instance just to |
| * define the webmodule for files it owns, assuming it uses projects for |
| * implementation of ear module. |
| * </p> |
| * <p> If needed a new implementation of this interface can be registered in |
| * global lookup. |
