It's already wrapped man, i just copied the code snippet from within <%%>
marker ;), and for System.out, or out.println, It's still the same problem.
If you looked at the exception you will find ClassNotFoundException at line
66 in the generated servlet, and this occurs withing the try block, so, i
think it's a problem of Connector. But the strange thing is that this
code worked fine on a normal java class???
