application.xml Deployment Descriptor Elements

 

The following sections describe the application.xml file.

The application.xml file is the deployment descriptor for Enterprise Application Archives. The file is located in the META-INF subdirectory of the application archive. It must begin with the following DOCTYPE declaration:

<!DOCTYPE application PUBLIC "-//Sun Microsystems, 
Inc.//DTD J2EE Application 1.2//EN" 
"http://java.sun.com/j2ee/dtds/application_1_2.dtd">

The following diagram summarizes the structure of the application.xml deployment descriptor.

 

The following sections describe each of the elements that can appear in the file.
