Tomcat and Servlet Debugging

[Simon Taylor <se...@nortelnetworks.com>]

I am new to Java and Tomcat having just inherited the admin of some servlets
from someone who has left the company.
I have a servlet that isn't doing what I expect.
It is littered with lines of the following type:-

writeError("Session was not created by superclass");

Which refers to :-

protected void writeDebug(Object msg)
  {
    if (debug==1) {
      Date date = new Date();
      System.err.println("[" + date.toString() + "] [debug] [" +
                         this.getClass().getName() + "] " + msg.toString());
      debugMsg = debugMsg
        + "<TR><TD BGCOLOR='#CCCCCC'>"
        + msg.toString() + "</TD></TR>\n";
    }
    return;
  }

This is throwing an error but I get no error in any of the Tomcat logs even
though I have a Context Logger set up to debug.
I have manually set debug = 1 at the top of the script recompiled and
redeployed and still no debug messages.
Where would these end up.

Reading around it looks like a better approach would be to use Log4J to
debug the servlet. I'd rather not do that if I can get away with a quick fix
using the existing code.
Comments pls.

That lines tells you that it's being printed out to Standard Error.

Which OS are you running on?

On Unix, both standard out and standard err get printed to 
TOMCAT_HOME/logs/catalina.out

On windows, I believe both go to the command console.
Try running tomcat by CDing to TOMCAT_HOME/bin and typing: catalina 
on the command line.  You should see another DOS window appear which will show 
any of those messages as they come up.
