The thrift compiler is no java program. It is a written in C++ and have quite a few dependencies (boost for instance if memory serves) that don't make distribution that easy. > (I'm not a thrift expert but did work on RMI in the JDK, some years go, so I > can guess what may be needed to generate the code.
