XWPErs,

I'm not sure this will work.  I haven't looked, but doesn't XWPE perform 
the compilation from the working directory for the file, i.e. the directory 
the file is in?  To have Javac perform correctly (if you are writing good 
Java code...  you are, aren't you?  :) ), you have to execute it from the 
top of the package hierarchy.  For example, suppose the fine folks at sun 
decided to use XWPE to edit the java.net package.  The "Socket" file would 
look like this:

===
package java.net;

import java.io.*;

public abstract class Socket
{
  //... Much stuff...
}
===

The file would be in:

/project/java/net/Socket.java

To compile this with javac, you must execute javac from:

~/project> javac java.net.*;

I think this will only work for java classes which aren't in 
packages...  which if you're writing real java could, you really shouldn't 
have.

I also believe in namespaces.

Ah, well, commence flaming...  (I don't know Perl, so if I missed 
something, just a little charring to the left please?)
