Hi Michael,

Apparently, after a quick look at the source code, Axis relies on an org.apache.axis.components.compiler.AbstractCompiler to perform the compilation. It turns out that there are currently only two concretisations of this: Javac (the default) and Jikes. From what I can see, the Jikes class calls an executable on the command line (not that I would recommend that), so it should be quite straightforward to adapt it to call gcj (well... in theory). However, I've done a few quick tests (outside Axis) and gcj doesn't seem to compile everything that Sun's javac handles yet (I'm using version 4.1.1 of gcj). Interfacing the Eclipse compiler might be a better bet. Presumably, it's also possible to have a org.apache.axis.components.compiler.EclipseCompiler that could call the compiler directly. I would expect an application such as Axis/Tomcat to gain a lot from a just-in-time compiler, so if you manage to have it running with gcj, some benchmarks would be really interesting.

Regards,

Bruno.

Taking Robert's advice, I will post the stack trace from catalina.out:

java.lang.RuntimeException: No compiler found in your classpath!  (you may
need to add 'tools.jar')
   at org.apache.axis.components.compiler.Javac.<init> (Javac.java:72)


I guess my next stop would have to be to grab the axis source tarball and
see how it decides what class to call for a java compiler, because
everything else in Fedora Core 5 calls the eclipse java compiler (which is
ALSO on my classpath)
