Hi

I have the following jboss-web.xml in my app to set root context.

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE jboss-web PUBLIC
    "-//JBoss//DTD Web Application 4.2//EN"
    " http://www.jboss.org/j2ee/dtd/jboss-web_4_2.dtd http://www.jboss.org/j2ee/dtd/jboss-web_4_2.dtd">

<jboss-web>
<context-root>/</context-root>
</jboss-web>


But I am getting this exception: 
ERROR [org.jboss.msc.service.fail] (MSC service thread 1-16) MSC00001: Failed to start service jboss.web.deployment.default-host./: org.jboss.msc.service.StartException in service jboss.web.deployment.default-host./: Failed to start service

Any idea? 

Thanks
