Building WARs 

Use

This creates a WAR file containing all the Web objects and deployment descriptors of a Web project.

The WAR file will also be created in the Web project when an EAR file that references the Web Module project is built.

Procedure

       1.      In the J2EE Explorer view, select the Web Module project.

       2.      From the context menu, choose Build WAR File.

Result

A WAR file with the same name as the Web project is created. You can now reference the WAR from an Enterprise project. See Adding Modules to Enterprise Projects.
