Re: Schema Discovery Support in Apex Applications

Sorry, I’m a new person in the APEX team. And I don't understand clearly who are consumers of the output port operator schema(s). 1. If the consumers are non-run-time callers like the application manager or UI designer, maybe it makes sense to use Java static method(s) to retrieve the output

Questions about the method JarHelper.getJar()

Hello All, I have a couple of questions about the usage of the method JarHelper.getJar(). 1. The implementation of the method JarHelper.getJar() takes a Java class as a parameter and tries to find the jar file that contains the Java class. If the class does not belong to a jar-file, it
