How to define/use a "patch" ?
Is there a way in glassfish to have a .jar that will contain "replacement" class so that they are loaded first instead of the glassfish class ?
As an example, I have provided a fix for the Issue 176 (
https://glassfish.dev.java.net/issues/show_bug.cgi?id=176 ) that prevent Java enum to be used as valid types in EL.
This involve replacing com.sun.el.lang.ELSupport, so I was just looking for getting the source of the class, patching and running it against my current version ...
Any ideas ?
