Have you been able to start up Tomcat without using the WebGoat script?

Tomcat seems to start for me when I run the "startup.sh" script.  However, I 
can't
find it under the running process list.

ubuntu@MVKS:/pentest/WebGoat-5.2$ sudo ./tomcat/bin/startup.sh 
Using CATALINA_BASE:   /pentest/WebGoat-5.2/tomcat
Using CATALINA_HOME:   /pentest/WebGoat-5.2/tomcat
Using CATALINA_TMPDIR: /pentest/WebGoat-5.2/tomcat/temp
Using JAVA_HOME:       /usr/lib/jvm/java-6-sun
ubuntu@MVKS:/pentest/WebGoat-5.2$ 

I do get some errors though when attempting to start WebGoat.  See below

ubuntu@MVKS:/pentest/WebGoat-5.2$ sudo sh ./webgoat.sh start80
Using CATALINA_BASE:   ./tomcat
Using CATALINA_HOME:   ./tomcat

Did you make sure that no other service is already bound to port 80?
