Multiple webapps in the same container ?

Hi all,

Is it necessary to deploy each webapp in a different tomcat instance.
If NO, how do I deploy all the webapps to the same instance. I face errors related to Perm, memory, scoket,etc.

If Yes, Then how do have multiple instances of Tomcat. I've been struggling to get through this.

Thanks in advance.

Yes, you can install multiple web applications (e.g. multiple war files) in 1 tomcat instance.

They must have different context root.

E.g. you can have localhost:8080/myapp1/index.jsp, and localhost:8080/myapp2/index.jsp

where myapp1 and myapp2 are the context roots.

Well I have deployed webapps in the similar fashion.
However, restarting tomcat leaves me with this

Here is the process output
[root@centos logs]# ps aux | grep java
user1 9458 3.2 17.7 630864 186056 ? Sl 22:44 0:24 /usr/java/latest/bin/java -Djava.util.logging.config.file=/usr/share/apache-tomcat/conf/ -Xms128m -Xmx256m -XX:MaxPermSize=256m -Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager -Djava.endorsed.dirs=/usr/share/apache-tomcat/endorsed -classpath /usr/share/apache-tomcat/bin/bootstrap.jar:/usr/share/apache-tomcat/bin/tomcat-juli.jar -Dcatalina.base=/usr/share/apache-tomcat -Dcatalina.home=/usr/share/apache-tomcat org.apache.catalina.startup.Bootstrap start

What am I missing ?

Your memory parameters are on the small side. About half of what you allow is going to be used up by Tomcat itself before any webapps even get deployed. Try bumping up mx to 512M or at least 384M.

An IDE is no substitute for an Intelligent Developer.
I agree. Here's the link:
