You can use the default interfaces that are provided with the J2EE Engine for the interfaces only. To do this, select the Use Default JAR Files checkbox.
Specify a name of a JAR file in the JAR field. You can browse the file system to locate that JAR file.
Specify a mapping name for the JAR file in the Mapping field. If you do not specify a mapping name, the file will be added with its name only.
Click the Addbutton. The new jar-mapping pair is added in the table above the fields.
