Multiple classloaders

[belaban]

Bela,

Thanks for the reply. To expand, Is there a similar feature to OSCache like a tag libarary that will allow cache control on sections of a JSP? Or is the cache mechanism purely URL based?

Also is there anywhere in the docs or example code out there where someone has tried caching JSP (replicable) to disk? I saw a mention of a squid based application of JBOSS Cache in the FAQ but have not found any good examples of that type of configuration yet.

Thanks,
-nate

We're talking reflection calls on fields not methods. so, java.lang.reflect.Field.set(obj, val) will not be intercepted. The way field interception is instrumented is that Javassist searches for code that references a field and inserts a call to the interceptor chain there instead of the field access. Field access is different than a method call in bytecode so you have to actually modify all classes that access a field if you want field interception.

I'm saying that this is a good thing that java.lang.reflect.Field is not intercepted. That way we can have easy non-intercepted access to fields.

Then again, we could easily implement everything we want to implement with only public method interception and the framework and semantics would be much simpler. AND, except for some bugs in redeployment, the AOP 1st iteration would be done for POJO.
