Precompiling the jar files?

[rosan samuel]

could anybody can explain what is the process of precompiling ? what's the usage?

What is the context in which you heard that term? I've heard of "precompiling" before, but it's not a common concept in Java.

I remember this from Microsoft Visual C++. Compiling C++ code can take a long time. To make the compilation process quicker, Visual C++ would precompile C++ header files for you - so it would compile parts of the program in advance, so that everytime you change something, it would not have to compile everything from scratch.

Maybe some IDEs for Java do a similar kind of thing, and that's where you heard of it?

I remembered doing pre compiling of jsp pages in one of my projects long back. I had done it using ant tasks. After that our GUI used to load faster.
