Question

I did a very simple grails app and tried to push it to my tomcat.

I did:

grails war

and placed the resulting war file into my tomcat/webapps directory and restarted it. The war is named as ec2.war. I am able to hit localhost:8080. But I am not able to hit: localhost:8080\ec2 – I get an 404 error code.

I’m getting the following stacktrace in catalina.out :

NFO: Deploying web application archive /var/lib/tomcat7/webapps/ec2.war
log4j:ERROR setFile(null,true) call failed.

What can be causing this error and how can I resolve it?

Note that tomcat runs in ec2 and here localhost refers to my public IP which in case 5.x.x.x.x.

You need to check the ownership of your tomcat folder. Do a:

ls -lisa /var/lib/tomcat7/webapps/

and check the ownership. If you just want to get it running, the easiest way is probably to do:

sudo chown -R root:root  /var/lib/tomcat
sudo chmod -R 777 /var/lib/tomcat

and do a

sudo /var/lib/tomcat/bin/startup.sh

But this is not the most secure way 🙂
