Re: Where does CGI script get HTTP_USER_AGENT and PATH values from?

One more update:
I modified my Java code to display more info about the Java environment on the server. When it displayed the output of System.getProperty("java.class.path"), turns out the classpath is blank! We had set it to the appropriate JRE 1.3 directories, but obviously not everywhere it needs to be set. So it appears that our problem is figuring out in which configuration file(s) the classpath needs to be set.
