| <h1 class="topictitle1">Creating an enterprise application project</h1> |
| <div><div class="section"><p>Enterprise application projects contain references to the resources |
| needed for enterprise applications and can contain a combination of Web modules, |
| JAR files, connector modules, EJB modules, and application client modules. |
| An enterprise application project is deployed in the form of an EAR file, |
| and is therefore sometimes referred to as an EAR project. The modules in an |
| enterprise application project are mapped to other J2EE projects. The mapping |
| information is stored in metadata files within the enterprise application |
| project. The metadata files are used for exporting the project to an EAR file |
| and for running the project on the server.</p> |
| <p>Like the other types of projects, |
| enterprise application projects can contain one or more project facets, which |
| represent units of functionality in the project. To be deployed as an EAR |
| file, the new project must have the EAR facet. Depending on what you want |
| to use the project for, you may want to enable other facets for the project.</p> |
| <p>When you create an enterprise |
| application project, it is recommended that you do not give it a name that |
| contains double-byte character set (DBCS) characters.</p> |
| <p>To |
| create a J2EE enterprise application project:</p> |
| </div> |
| <ol><li class="stepexpand"><span>In the J2EE perspective, click <span class="menucascade"><span class="uicontrol">File</span> > <span class="uicontrol">New</span> > <span class="uicontrol">Enterprise Application Project</span></span>.</span></li> |
| <li class="stepexpand"><span>In the <span class="uicontrol">Name</span> field, type a name for the new |
| project. </span></li> |
| <li class="stepexpand"><span>To change the default project location, clear the <span class="uicontrol">Use |
| default</span> check box under <span class="uicontrol">Project contents</span> and |
| select a new location with the <span class="uicontrol">Browse</span> button.</span></li> |
| <li class="stepexpand"><span>Click <span class="uicontrol">Next</span>.</span></li> |
| <li class="stepexpand"><span>Select the check boxes next to the facets you want this project |
| to have and select a version number for each facet. </span> You can also |
| choose a preset combination of facets from the <span class="uicontrol">Presets</span> list, |
| and you can also find out more about the requirements for each facet by right-clicking |
| the facet name and then clicking <span class="uicontrol">Show Constraints</span>.</li> |
| <li class="stepexpand"><span>If you want to limit your 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></li> |
| <li class="stepexpand"><span>Click <span class="uicontrol">Next</span>.</span></li> |
| <li class="stepexpand"><span>On the J2EE Modules to Add to the EAR page of the wizard, select |
| the existing modules that you want to add to the new enterprise application |
| project. </span></li> |
| <li class="stepexpand"><span>You can also create new modules to add to the project:</span><ol type="a"><li class="substepexpand"><span>Click the <span class="uicontrol">New Module</span> button.</span></li> |
| <li class="substepexpand"><span>If you want to create one module, clear the <span class="uicontrol">Create |
| default modules</span> check box, select the type of module you want |
| to create, click <span class="uicontrol">Next</span> and follow the New Project wizard |
| for that type of project.</span></li> |
| <li class="substepexpand"><span>If you want to create more than one module, select the <span class="uicontrol">Create |
| default modules</span> check box, select the check boxes for each type |
| of project you want to create, and click <span class="uicontrol">Finish</span>. </span> You can enter a name for each module. Each of these modules will have |
| the default settings for that type of project and they will have the same |
| server target as the new enterprise application.</li> |
| </ol> |
| </li> |
| <li class="stepexpand"><span>Click <span class="uicontrol">Finish</span>.</span></li> |
