> JBoss wrongly uses a shared environment for all EJBs in a WAR module or in an EJB module if there are JAX-WS annotations on some classes.
> The problem can be reproduced with the help of the attached application. Steps to reproduce:
> 1. Build the application and deploy the jar into JBoss.
> 2. Deploy file ectx-jboss-beans.xml. Observe the following (expected!) output in the console:
> 13:10:27,743 INFO  [STDOUT] Sc1: [value1]
> 13:10:29,960 INFO  [STDOUT] Sc2: [value2]
> 3. Undeploy ectx-jboss-beans.xml and the application jar.
> 4. Modify Sc2Bean.java, uncomment @WebService annotation.
> 5. Build the application and deploy the modified jar into JBoss.
> 6. Deploy file ectx-jboss-beans.xml. Observe the following (wrong!) output in the console:
> 13:15:13,001 INFO  [STDOUT] Sc1: [value2]
> 13:15:14,753 INFO  [STDOUT] Sc2: [value2]
> There is an additional problem that manifests itself at undeploy of the application with the shared environment context: there are multiple exceptions like the following
> 14:13:18,965 WARN  [org.jboss.kernel.plugins.dependency.StartStopLifecycleAction] Error during stop for jboss-switchboard:appName=ectx,module=ectx,name=Sc2Bean: javax.naming.NameNotFoundException: ORB not bound

> The root cause of the problems is in class org.jboss.reloaded.naming.deployers.ComponentNamingDeployer, line 63:
>        // If the deployment is a web module, then java:comp == java:module
>        // (See JavaEE6 Spec, section EE.5.2.2). So we create a MCJavaEEComponent,
>        // which uses the same context as its parent JavaEEModule
>        boolean useJavaModuleContext = this.informer.belongsToWebModule(unit);
> Why this is wrong? For the following reasons:
> 1. I do not think that the mere presence of @WS annotations turns an EJB module into a web module. Yes, some web infrastructure is needed to provide HTTP transport, but this is an implementation detail.
> 2. Next, "JavaEE6 Spec, section EE.5.2.2" says: "For historical reasons, the java:comp namespace is shared by all components in a web module. To preserve compatibility, this specification doesn't change that.". The thing is: historically it was not possible to define EJBs in a web module, at least, not according to the previous JavaEE specifications. So historical reasons are applied only for components that historically could be deployed in a web module.
> 3. Even more, "historically" JavaEE developers expect that EJBs do NOT share their java:comp namespace.
