Do you call in your application Thread.setContextClassLoader()? If not,
wrapping calls to execute scripts into something like
ClassLoader old = Thread.getContextClassLoader();
Thread.setContextClassLoader(Loader that you use to load js.jar);
try {
call script evaluation
} finally {
Thread.setContextClassLoader(old);
}
then it should help Rhino 1.5R3. It uses Thread.getContextClassLoader()
as a parent loader for generated classes and if that loader can not find
Rhino classes, you will get exactly the problem you described.
