VFS runtime generated class file not loaded

[debasisj]

JBOSS explodes the WAR file into some temp vfs folder.

My application generate some class on the runtime which stores in temp/vfs/.../WEB-INF/classes.

When application tries to load that class, it can't.

If I put that class on deployment time which packaged into WAR file only then it can be loaded. How can I load those dynamically generated classes on runtime without packaging into WAR.

Temp files are complete impl details, hence I cannot see how it could work.

But you could mount some "virtual" resources via VFS API.

e.g. this is how we switch / modify JPA config files in CapeDwarf:

If I create the full path (where the runtime generated classes to be dropped) inside the packaged WAR and deployed it. It works . Could you please explain why it happens?

I'm not following what exactly do you do to make it work.

WAR exploded into a TMP folder, now our application generates some java files and compiled class files on the fly inside WEB-INF/classes.  Now whenever application tries to load those generated classes then it says ClassNotFoundException.

Suppose our class package is: x.y.z and if I create a folder structure like x/y/z inside the WEB-INF/classes in packaged WAR then it works.

How JBOSS 7.1 application class loader works?

Thanks.
