manual tomcat 5 install on iseries

Im trying to install tomcat 5 on my iseries. I downloaded and extracted the
zip file into /tomcat5. I modified the catalina.sh file by adding
"JAVA_HOME=/QIBM/ProdData/Java400/jdk15" and "os400=true". From qsh, when I
try to start the server, I get the following:

catalina.sh

/tomcat5/bin/catalina.sh: 001-0019 Error found searching for command tty.
No such path or directory.

Using CATALINA_BASE: /tomcat5


Using CATALINA_HOME: /tomcat5


Using CATALINA_TMPDIR: /tomcat5/temp


Using JRE_HOME: /QIBM/ProdData/Java400/jdk15


Using CLASSPATH: /tomcat5/bin/bootstrap.jar


Usage: catalina.sh ( commands ... )


commands:


debug Start Catalina in a debugger (not available on OS400)


debug -security Debug Catalina with a security manager (not available on
OS400)

jpda start Start Catalina under JPDA debugger


run Start Catalina in the current window


run -security Start in the current window with security manager


start Start Catalina in a separate window


start -security Start in a separate window with security manager


stop Stop Catalina

version What version of tomcat are you running?
