You will have to ask your ISP to change the settings globally since you are in a shared host. For my ISP they have a fairly high limit (almost 2GB of memory allocated), so I would ask for the sky…

By the way, the steps in this article still work on:
- Liferay 6.0.5
- Tomcat 6.0.26
- Java 1.6.0_21

Hi Steve. Great article. There isn’t much (Liferay) information around on how to deploy the standalone war. I missed your comment about automatic deployment of the plugins/portlets/themes, etc. i got Liferay working, but had indeed the problem of automatic deployment. It took me a while to figure out why this doesn’t work in this setup. If the additional dependencies are loaded by Tomcat at startup from /lib/ext (add to common.loader in /conf/catalina.properties) everything works fine. If the additional dependencies are added to the liferay context in /WEB-INF/lib, automatic deployment and registration of plugins/portlets/themes fails. Perhaps it has something to do with class loaders etc?

If you know how to solve this, it would be nice to hear. Otherwise, it would be nice how one could work around this by manually installing and registering the plugins/portlets/themes.

Thanks for this article anyway. Helped a lot!

With regards,

Andor Vierbergen

Sounds like you got the basic Tomcat mult-instance steps down. Since setting up multiple instances of Tomcat on the same box is not the point of this article, you might want to refer to another resource like this: http://azeditech.com/tomcat/multiple-tomcat-instances.html

I have an issue with multiple tomcat instances. I was building 5.3 from source and deployed it to tomcat. I left there only /webapp, /lib/ext, conf/server.xml, and modified /bin/startup.sh&shutdown.sh script for having different $CATALINA_BASE. I setup server.xml for connector to listen on different IP and changed hostname.

/opt/jdk1.6.0_16/bin/java -Dnop Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager -Xms766m -Xmx1024m -XX:MaxPermSize=512m -Djava.endorsed.dirs=/opt/aaa/apache-tomcat-6.0.20/endorsed -classpath :/opt/aaa/apache-tomcat-6.0.20/bin/bootstrap.jar -Dcatalina.base=/opt/apache-tomcat-6.0.20 -Dcatalina.home=/opt/aaa/apache-tomcat-6.0.20 -Djava.io.tmpdir=/opt/apache-tomcat-6.0.20/temp org.apache.catalina.startup.Bootstrap start

It boots up, listens on that IP and port, but doesn’t respond at all, it’s like the requests get lost and doesn’t even get logged.

Hi Steve,

Great article! I got it working, but the problem I am having is that , when I deploy a portlet, it is not seen in either of the instances. The portlets deploy without an error, but when you go to add an application, you do not see the deployed portlets at all.

Kudos on a great writeup. Easy to read, easy to follow.

My question goes to your statement on plug-ins and themes not being able to be installed automatically. I’ve been attempting to install plug-ins such as WOL with mixed success. I was wondering if you have any words of wisdom? Right now i can get the war(s) up and running, they just don’t appear to want to integrate with the liferay portal/database.

Many thanks.

This article is great, I’ve been able to deploy a working liferay application following the instructions in this article. I agree with karthik – an article on deploying portlets and themes would be great.

OK, I resolved that issue
