    "due to the fact System.out.println(...) is dead."

For my installation, System.out and System.err are under the
control  of /bin/java.  So I start ApJ manually out of a bash
shell script (I don't know redirection tricks in the bourne shell...)
like this:

  #!/usr/local/bin/bash

  # set up the CLASSPATH and LD_LIBRARY_PATH....

  PROPS=/opt/jserv10b3/conf/jserv.properties
  LOG=/opt/jserv10b3/logs/jserv.log

  java -classpath $CLASSPATH org.apache.jserv.JServ $PROPS > $LOG 2>&1  &

     > $LOG says "write stdout to here"

and
  
    2>&1  says  "write stderr to the same place as stdout"

With this, both stdout and stderr go to the standard jserv log.
(I don't know how to find the results of log (), however.)

System.out.println() goes to the console that started up the JVM. 
So, if the httpd process starts the JVM (ie: Apache JServ in automatic mode), 
then the System.out goes to the console of the user that started the httpd 
(ie: root). If you start the JVM (and Apache JServ process on the command 
line, then it goes to that user who started the JVM process.

There's no way to access to the console while JServ or Apache is running
as a service.
You can start it manually from the MS-Dos prompt, and then the console
ends up in the MS-Dos prompt window....

1. read Ari's excellent article: http://www.magiccookie.com/computers/apache-jserv/. Search for 'Running Apache JServ'.
2. change the ApJServManual directive from off to on. This is located in the \apache\jserv\mod_jserv.conf file.
3. invoke JServ as you would any other java program. I made a cmd script to simplify this called 'jserv.cmd', which I placed under \apache\jserv for easy reference. As you can see fom the following, the 1.2 interpreter is invoked with an explicit classpath to rt.jar and the ApacheJServ.jar. The class Jserv is executed with the jserv.properties file as the sole argument.

   contents of \apache\jserv\jserv.cmd:
\java\jdk1.2\bin\java -classpath /java/jdk1.2/jre/lib/rt.jar;/apache/jserv/ApacheJServ.jar org.apache.jserv.JServ \apache\jserv\conf\jserv.properties

4. At this point you're ready to rumble. Remember, you have to start both the Apache webserver and jserv now (thus the 'manual'). Open a shell, execute the \apache\jserv\jserv.cmd (you can typically leave the .cmd off), and you should be set (at least I was).

          have them use 

          log("error string); 

          or
          getServletContext.log(e, "an error ");


          or
          use the following and write the error stack trace back to the browser or to the log.

                  /* PrintStackTraceAsString from com.oreilly.servletServletUtils from 
                          Java Servlet Programming, by Jason Hunter and William Crawford, O'Reilly, 1998 
                  */
                  public String getStackTraceAsString(Exception e){
                          ByteArrayOutputStream bytes = new ByteArrayOutputStream();
                          PrintWriter writer = new PrintWriter(bytes, true);
                          e.printStackTrace(writer);
                          return bytes.toString();
                  }
