Hello Christine Thanks for helping me. I forgot to mention that other methods (in my main class) which are not using my Java XSLT Extensions, just work fine. Therefore I assume that my applet tag is correct since the web browser finds the MyApplet class an all related file such as DTD and XML. The MyApplet class in turn instantiates my application (class) for message processing with Xalan.
I also tried to run my transformation method in the init() method of the applet and surprisingly got the right return value. it seems that problem is limited to calling the applets transformation method from JavaScript. I also have no clue how to debug/breakpoint this situation since the things happen between the web browser(HTML/JavaScript) and the applet.
