unable to deploy war file in jboss AS 7.1.1 - jboss

Question

I am new to jboss-AS. I am trying to deploy a war file in deployments directory, but I am getting war file renamed with .failed name.
say xxx.war is kept in deployments dir,the new file is also found after some time with www.war.failed.
content of failed war file are as below:
cat xxx-1.1.war.failed
{"JBAS014653: Composite operation failed and was rolled back. Steps that failed:" => {"Operation step-2" => {"JBAS014671: Failed services" => {"jboss.web.deployment.default-host.\"/xxx-1.1\"" => "org.jboss.msc.service.StartException in service jboss.web.deployment.default-host.\"/xxx-1.1\": JBAS018040: Failed to start context"}}}}[rhino#Rhino deployments
i tried everything to troubleshoot it with the help of google with NO success !!
i tried with fresh war files still not worked.
I am kind of stuck with this for the last one week..
Please help!!
Thanks..

Answer 1

The error is in the stack trace of the log:
Caused by: java.lang.NullPointerException
at com.nsn.claroUI.util.ClaroUIContextListener.<clinit>(ClaroUIContextListener.java:74) [classes:]

You need to see what's at line 74 of com.nsn.claroUI.util.ClaroUIContextListener.
