Java jar - downloadable? or only compilable?

[J.V.]

In order to get the Java implementation I have to compile some C++ code,
but have limited resources on my machine at this time to install a compiler.
Where can I get the Java jar to drop into my project for Win32?

thanks

In order to *use* the Java implementation, you need to build that same C++ code -- the protocol compiler.  The Java protobuf runtime is mostly useless without it.  However, you can get a prebuilt copy of protoc.exe for windows here:

http://code.google.com/p/protobuf/downloads/detail?name=protoc-2.1.0-win32.zip

You can then use it to build the Java code.
