Perhaps the IBM JDK6 has some bugs running on V5R4?

Some other things you might do to shed more light on this:

- Add these lines to the end of conf/logging.properties:

        org.apache.catalina.startup.Bootstrap.level = ALL
        org.apache.catalina.startup.ClassLoaderFactory.level = ALL
        
        Then stop/start Tomcat.  You should see a log entry like:
          location X is file:/wintouch/tomcat/lib/catalina.jar
        
        
- If you do see an entry as above try compiling and running the
following from /wintouch/tomcat which tests finding a class:

>>>>>>>>>>>>>>>>>>>>>>>>>BEGIN
import java.io.File;
import java.net.URL;
import java.net.URLClassLoader;

public class FindClass {
        public static void main(String[] args) {
                try {
                        URLClassLoader loader = new URLClassLoader(
                                new URL[] {new 
File("/wintouch/tomcat/lib/catalina.jar").toURI().toURL()});
                        loader.loadClass(args[0]);
                        System.out.println("URLClassLoader found class '" 
+args[0] +"'");
                }
                catch (Exception e) {
                        e.printStackTrace();
                }
        }
}
<<<<<<<<<<<<<<<<<<<<<<<<<END
      * Save this to FindClass.java in /wintouch/tomcat
      * Compile it: javac FindClass.java (or compile on another machine
        and copy the resulting .class file)
  * Run it: java -cp . FindClass org.apache.catalina.startup.Catalina

If this fails then my guess would be that there's a JDK6 problem on V5R4
or there's a problem with your catalina.jar.  If it succeeds then some
Tomcat file(s) aren't as correct and/or authorized as you think they are
-- or you're leaving out some other important factor.
