Ok I found out how to make NetBeans open my file of origin from debug
information in compiled JavaScript, without JSR-045 or external JavaScript
debugger..
When calling ClassCompiler.compileToClassFiles use the asp/jsp file name of
origin, and in the .asp to .js translator keep the line numbers in sync. The
filename passed to the compiler should be relative, not absolute, otherwise
NetBeans will show it as a hidden source file.
With this trick I can debug step by step and see in the watch window all
variables that the JavaScript compiler is able to optimize to Java
variables. I cannot set breakpoints though, and of coarse the JavaScript
Objects and Arrays will show the underlying Java implementation in the
variables window. But for primitive values like strings or numbers the debug
information I get is enough.
