The first hit on a Google search for "weblogic appc":
The appc compiler generates and compiles the classes needed to deploy EJBs and JSPs to WebLogic Server. It also validates the deployment descriptors for compliance with the current specifications at both the individual module level and the application level. The application-level checks include checks between the application-level deployment descriptors and the individual modules as well as validation checks across the modules.
weblogic.appc performs the following EJB-related functions:
* Generates WebLogic Server container classes for the EJBs.
* Checks all EJB classes and interfaces for compliance with the EJB specification.
* Checks deployment descriptors for potential configuration problems. For example, if there is a cmp field declared in ejb-jar.xml, appc verifies that the column is mapped in the weblogic-cmp-rdbms.xml deployment descriptor.
Runs each EJB container class through the RMI compiler to create RMI descriptors necessary to dynamically generate stubs and skeletons.
By default, appc uses javac as a compiler.
I understand it more like converts .java into .class + just little more work(that's weblogic specific). Do we have something like websphere.appc to do something similar but for websphere?
