Application Assembler

The application assembler is the company or person who receives application modules from component providers and may assemble them into a Java EE application EAR file. The assembler or deployer can edit the deployment descriptor directly or can use tools that correctly add XML tags according to interactive selections.

A software developer performs the following tasks to deliver an EAR file containing the Java EE application:

• Assembles EJB JAR and WAR files created in the previous phases into a Java EE application (EAR) file

• Specifies the deployment descriptor for the Java EE application (optional)

• Verifies that the contents of the EAR file are well formed and comply with the Java EE specification
