    [ https://jira.jboss.org/browse/JBAS-8528?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12557297#action_12557297 ] 

jaikiran pai commented on JBAS-8528:
------------------------------------

Actually, this is a completely different issue. JBoss AS6 follows the Java EE6 spec which introduces the app/module naming convention. As per the spec, you can have more than one module with the same module name (or more than one app with the same app name). The module name (or app name) is the name of the deployment without the suffix. So in your case the module name turns out to be MyApp for both the deployments. This isn't allowed. You either have to rename the deployments or override the module name through the deployment descriptor (more details in the Java EE 6 spec).

>    Affects Versions:  6.0.0.M5
>         Environment: Linux 2.6.18-8.el5 #1 SMP x86_64 GNU/Linux
> Java 64-Bit Server VM "1.6.0_21"

> Can be seen with M5, also with Snapshot as of 2010-10-10.
> This might have the same root cause as JBAS-6335, but JBAS-6335 is reported to be fixed, whereas this issue definitely exists.
> If you have 2 or more files in the deploy folder, which have the same name with different suffixes, the deployer will run into the following error (full log will get attached):
> [AbstractKernelController] Error installing to Real: name=vfs:///mnt/san/develop/nbr/XXX/jboss/xxx/deploy/MyApp.war state=PreReal mode=Manual requiredState=Real: org.jboss.deployers.spi.DeploymentException: Error deploying: jboss.naming:application=MyApp
> Caused by: java.lang.IllegalStateException: jboss.naming:application=MyApp is already installed.
> e.g. if you have an WAR and a SAR which have the same name:
> - MyApp.sar
> - MyApp.war
> or the same with war and probably any other combination of it:
> - MyApp.ear
> - MyApp.sar
> Workaround is to rename one of the files, which leads to successful deployment.
