You'll have trouble doing this with gcj, since Tomcat relies on object
serialization and RMI (IIRC), which aren't currently supported by
libgcj.

But to answer your question, compile class files as you would sources:

  gcj -O2 -c *.class
  gcj -O2 *.o --main=name-of-main-class -o name-of-executable

Find out how Tomcat is invoked (there is probably a shell script
somewhere).  The main entry point should be identified by the `java'
command line.
