Component Archive
From Wsmx-WIKI
A component archive is a jar with a .wsmx extension and an agreed upon internal structure. The class files that make up the components implementations go to /classes, the archives deployment descriptor (if any) goes to /META-INF, libraries go jarred to /lib. WSMX uses custom classloaders that extract embedded jars, resolve load requests to the individual libraries, and provide isolation domains which allow components to load different version of the same class.
