According to the Java™ 2 Platform Enterprise Edition (J2EE) specification, application clients are packaged in archive files with a JAR extension. In addition to the classes of the application client, these JAR files contain a META-INF/ directory, in which deployment descriptors are stored.
In J2EE Engine, the application clients are deployed with two deployment descriptors:
· A standard deployment descriptor, which is defined by the J2EE specification
· An additional deployment descriptor, which is specific for J2EE Engine and is defined by appclient-j2ee-engine.dtd.
You can package and deploy an application client using the Deploy Tool that J2EE Engine provides.
