The class files that are packaged in jar files should not depend on the OS or the platform (that is what makes Java platform neutral). The class files may depend on the version of the JDK being used.

If you are hoping to see the Java source files for the class files then they are not normally included in jar files.

And welcome to the Ranch

There is no such thing as a "32-bit JAR file". Java code is independent of the underlying platform. It doesn't matter whether you compile your Java source code on a 32-bit or on a 64-bit JDK - you'll get the same byte code out of it.

The 32-bit or 64-bit is only relevant when your program contains native code, not written in Java, but for example in C or C++.

Problem was solved. thank you all for helping and giving advices.
