Multiple webapps deployment on tomcat

[Rafael Nathan]

Hi,

I have setup Apache Tomcat on my CentOS machine and it seems to work as a charm initially and a service tomcat start leaves me with output as such
Using CATALINA_BASE: /usr/share/apache-tomcat
Using CATALINA_HOME: /usr/share/apache-tomcat
Using CATALINA_TMPDIR: /usr/share/apache-tomcat/temp
Using JRE_HOME: /usr
Using CLASSPATH: /usr/share/apache-tomcat/bin/bootstrap.jar:/usr/share/apache-tomcat/bin/tomcat-juli.jar

Further, I deployed the apache roller webapp and it works well and as soon as I deploy another instance of Apache roller the container crashes I wonder why ?
A restart now leaves me with this :
Using CATALINA_BASE: /usr/share/apache-tomcat
Using CATALINA_HOME: /usr/share/apache-tomcat
Using CATALINA_TMPDIR: /usr/share/apache-tomcat/temp
Using JRE_HOME: /usr
Using CLASSPATH: /usr/share/apache-tomcat/bin/bootstrap.jar:/usr/share/apache-tomcat/bin/tomcat-juli.jar

I am unable to deploy more than one webapp

Here is my /etc/init.d/tomcat script
#!/bin/bash

# processname: tomcat

export PATH
CATALINA_HOME=/usr/share/apache-tomcat

status() {
SHUTDOWN_PORT=$(netstat -vtnl|grep 8005|wc -l)
if [ $SHUTDOWN_PORT -eq 0 ]; then
echo "tomcat is not running..."
RETVAL=1
exit $RETVAL
else
echo "tomcat is running..."
RETVAL=0
exit $RETVAL
fi
}

case $1 in
start)
su - admin -c $CATALINA_HOME/bin/startup.sh
;;
stop)
su - admin -c $CATALINA_HOME/bin/shutdown.sh
;;
restart)
su - admin -c $CATALINA_HOME/bin/shutdown.sh

;;
status)
status

*)
echo $"Usage: tomcat {start|stop|restart|status}"
exit 1
esac

exit $RETVAL


Please help. Need to get it working badly

Thanks in advance.

Welcome to the JavaRanch, Rafael!

You cannot have 2 identical instances of the Tomcat server running at the same time on the same machine. The TCP/IP architecture only allows one program to listen on any one port.

There is some confusion as to what you mean when you say "multiple webapps". A single copy of Tomcat can hold more than one webapp - there's no need to start a second Tomcat, if that's what you are doing.

Hi Tim,

Thanks for the quick reply.

I unpacked the webapp Apache roller in the webapps directory with the name roller1 and restarted tomcat. Yet again, I unpacked another copy of Apache roller in the webapps directory with the name roller2 and restarted tomcat.

However, tomcat crashes and I am left with nothing

Please help

No even a stack trace?
