Re: dynamic-environment class path issues

Hi

I will look into sixx, I did look at Kawa, but it seemed weird to me as
well.

Meanwhile, the issue I'm having is that the external classpath is not
getting reflected inside of the SISC classloader(?). I'm running using
Eclipse, and everything works in general - except for code that does
something with SISC. Setting an external CLASSPATH works fine for everything
in general, except when SISC comes into play.

At least, I think this is what is going on... I'm not sure. The trouble, for
instance is, that SISC is able to find the java class which has the method
I'm calling using S2J - but from within that class, the method calls
Class.forName, and THAT is failing.

Something SISC is doing is causing the class-loader to lose it's
class-path...
