my java and python

From the code writing perspectives, java is more annoying than python (much more). But till now application which written on java got more appreciation than the others, even they gave the same result. Is that just because writing on java is more difficult?? :)

Because of that difficulties than came jython and groovy which seems very interesting. Jython is pure python written on java which ofcourse got full access to all java class libraries (accessing java class libraries with that simple python style, wow that was ammazing). Than groovy is the different things which gave simplecity of java with their red and blue side. The red side is they offer simpler method for writing java code, and the blue code just offer different perspectives about java (much more different but also much more fun because it's simplicity). Both 'languange' (jython and groovy) in advance could be compiled to java class. and both gives interactive shell.

But still when I check to the java development site I got that they only suggest those languge for prototyping. Do I need to learn jython or groovy??? or I just need to learn python and/or java, and than glue them together. Or I can stand only on one of them; since all of them provide their own library, framework, fans, etc.

Oh I forget one more things, ruby with it fomous web framework ruby on rails. They also as simple as python also with java support on jRuby and bundeled ruby on rail web development on current netbeans version. But don't know yet RoR framework performance on high scalability site.
