Using gcj

 Note: I don't know if I automatically get CC'd when someone replies to 
this posting, so please copy me at slf29@cas.org, if you think it may be 
necessary.

I am a newbie to gcj (and gcc) and I am having trouble getting it to 
work with third party libraries.

I have a Java program, ACDProcessor, which uses Xerces and Xalan, as 
well as GNU regular expressions and log4j and I don't remember what 
else. I have included the appropriate jars in the CLASSPATH and with the 
-I command line option. I also included:

  -l-org-w3c-dom \
  -l-org-xml-sax \

on the command line to pick up gcj's versions of these libraries. The 
full command that I am running is listed at the bottom of this message 
for reference.

When I run gcj (via my shell script), I get errors like this:

/home/slf29/props/org/cas/properties/acd/ACDProcessor.java:410: 
undefined reference to `javax::xml::transform::stream::StreamResult::class$'
/home/slf29/props/org/cas/properties/acd/ACDProcessor.java:410:

/home/slf29/props/org/cas/properties/acd/ACDProcessor.java:410:

/home/slf29/props/org/cas/properties/acd/ACDProcessor.java:84: undefined 
reference to `org::apache::log4j::Logger::getLogger(java::lang::Class*)'

Notice that it is not finding log4j, which does not have a native gcj 
implementation, nor is it finding xerces, which is supposed to be 
implemented in native code for gcj, nor can it find some XML-related 
classes in javax.xml.transform, which is part of the Java standard XSLT API.

What am I doing wrong?

Here is the command file I am running:
