You can use the Import wizard to add EJB 3.1 classes or a POJO class from JAR files to an EJB 3.1 project. You can import the class files from the directory system or from a JAR file or .zip file. After you choose the class files that you want to import, the wizard creates a <project-name> folder, imports the specified class files to that folder, and adds the folder to the default class path. You can navigate the <project-name> folder in the Enterprise Explorer view.
