Re: class to JavaClass file
What I am trying to do is change in constant pool of every class my
application loads (not all but that also includes some library classes ) for
that im trying to change instance of Class that findSystemClass() returns
into that of JavaClass so that I can change in the constant pool and then
use defineClass on it. ClassParser converts DataInputStream into JavaClass,
how can I make it to change Class into JavaClass.
Thanks

You can load class file as resource with system classloader, but you can not
to define it twice in the same classloader:
JavaClass jclass = new
ClassParser(Object.class.getResource(Object.class.getName().replace('.','/')
+ ".class")),Object.class.getName());
