Changing context root for a web app under JBoss As 7

Question

I want to change context root from "/war_name" (by default) to "/".

Thus, I created a jboss-web.xml file that I pushed in WEB-INF directory.

Content of this file is :

<?xml version="1.0" encoding="UTF-8"?> <jboss-web>     <context-root>/</context-root> </jboss-web> 

Unfortunately, this causes the following error during war deployment :

ERROR [org.jboss.msc.service.fail] (MSC service thread 1-4) 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     at org.jboss.msc.service.ServiceControllerImpl$StartTask.run(ServiceControllerImpl.java:1780) [jboss-msc-1.0.1.GA.jar:1.0.1.GA]     at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1110) [:1.7.0_01]     at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:603) [:1.7.0_01]     at java.lang.Thread.run(Thread.java:722) [:1.7.0_01] Caused by: java.lang.IllegalArgumentException: Child container with name  already exists     at org.apache.catalina.core.ContainerBase.addChildInternal(ContainerBase.java:804)     at org.apache.catalina.core.ContainerBase.addChild(ContainerBase.java:792) 

However, when I put some directory name like : /RoomManagement, I don't have this issue. But if I use this one, I couldn't access to JSPs that aren't in /RoomManagement.

Have you an idea for well-configuring context-root to "/" ?

Answer 1

It looks like there is another app that's running at the root context "/".

You may have to delete the other app or move it to a different context before you can assign your app to the root context.

If the conflicting app is JBoss AppServer root itself, you can disable that using the following (enable-welcome-root="false")

<subsystem xmlns="urn:jboss:domain:web:1.0">   <connector name="http" protocol="HTTP/1.1" socket-binding="http" scheme="http"/>   <virtual-server name="localhost" enable-welcome-root="false">     <alias name="example.com"/>   </virtual-server> </subsystem>
