Re: Loading .java Files

I don't believe that beanshell is 100% backwards compatible with Java.
Especially Java 1.6.
bsh java compatibility syntax is pre 1.4.
Plus even if the syntax is compatible, as you have discovered, its use case
is not.
You can load a java class file into bsh but you cannot access it from java
natively (only from bsh).
The internal bits it creates from parsing "java" code are not  java JVM
Bytecode.  Its beanshell interpreted runtime codes.   So in some cases you
might get away with reading pure java files, in other cases maybe not.
In no cases is it exactly the same.

If you want pure java you need to use javacc or equivalent and use a
classloader.
Its actually not as complicated as one might imagine.

As for beanshell2 ... I'll let others comment, I haven't followed it for a
while.

Yes. Java isn't Bsh compatible.
But Bsh is Java compatible? I mean that Bsh can eval successfully every
script in Java-1.4 syntax?

I doesn't meant Bsh with "not elegant". I meant that my code removes the
"class {}" lines before loading the script.

Hm, I cannot find any docs at http://code.google.com/p/beanshell2/.

What are the enhancements to the original Bsh?

Thank you!
