JBoss Tools provides project templates for different types of JBoss projects. In this section, we will create a Java EE project for an EJB 3.x application. Select File | New | Other in Eclipse IDE. In the New wizard, select the JBoss Central | Java EE EAR Project wizard. Click on the Next button:
The Java EE EAR Project wizard gets started. By default, a Java EE 6 project is created. A Java EE EAR Project is a Maven project. The New Project Example window lists the requirements and runs a test for the requirements. The JBoss AS runtime is required and some plugins (including the JBoss Maven Tools plugin) are required for a Java EE project. Select Target Runtime as WildFly 8.x Runtime, which was created in the preceding section. Then, check the Create a blank project checkbox. Click on the Next button:
Specify Project name as jboss-ejb3, Package as org.jboss.ejb3, and tick the Use default Workspace location box. Click on the Next button:
Specify Group Id as org.jboss.ejb3, Artifact Id as jboss-ejb3, Version as 1.0.0, and Package as org.jboss.ejb3.model. Click on Finish:
A Java EE project gets created, as shown in the following Project Explorer window. Delete the jboss-ejb3/jboss-ejb3-ear/src/main/application/META-INF/jboss-ejb3-ds.xml configuration file. The jboss-ejb3 project consists of three subprojects: jboss-ejb3-ear, jboss-ejb3-ejb, and jboss-ejb3-web. Each subproject consists of a pom.xml file for Maven. Initially the subprojects indicate errors with red error markers, but these would get fixed when the main project is built later in the chapter. Initially the subprojects might indicate errors with red error markers, but these would get fixed when the main project is built later in the chapter. We will configure a data source with the MySQL database in a later section. The jboss-ejb3-ejb subproject consists of a META-INF/persistence.xml file within the src/main/resources source folder for the JPA database persistence configuration.
We will use MySQL as the database for data for the EJB application. In the next section, we will create a data source in the MySQL database.
