Deployment issue with Jboss AS7( Child container with name already exists)

[jitendra.daswani]

Hi,

I am getting following error while deploying the war file.

I am using Jboss AS7

2014-03-17 08:46:29,357 ERROR [org.jboss.msc.service.fail] (MSC service thread 1-1) MSC000001: 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

I did some changes in standalone.xml file "enable-welcome-root="true" to " enable-welcome-root="false" without restarting the server.

Attached server.log file also for details information.

Can anybody help me to resolve this issue?

I'm new to JBoss but it looks like you've overriden the default settings with a WEB-INF/jboss-web.xml in your WAR file.

I personally followed this post a few hours ago and I've had the exact same error message with:

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

<jboss-web>

    <context-root>/</context-root>

</jboss-web>

and

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

<jboss-web>

    <context-root></context-root>

</jboss-web>

Depending on your need, just don't override this setting to have the default behavior or use <context-root>myapp</context-root>

Hope this helps.
