[jboss-jira] [JBoss JIRA] (AS7-4240) NameNotFoundException thrown when trying to read java:*/env context in Servlet container.

[Robert Edgecombe (JIRA)]

    [ https://issues.jboss.org/browse/AS7-4240?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12678206#comment-12678206 ] 

Robert Edgecombe commented on AS7-4240:
---------------------------------------

So how do I bind something into java:module?
The JavaEE spec states that the server provides a tool for setting environment entries and this is the only tool I have seen that could do it.

I cannot find any documentation for this.

Including jboss-web.xml is not a proper solution.

> We have many J2EE 1.4 apps that need to be migrated from Oracle Application Server
> These applications rely on configuration using Environment Entries 
> Most of the answers to issues I have read indicate that this is done using jboss-web.xml but this is not an acceptable solutin as it requires repackaging of the deployment artifact for different servers and different environments and is therefor contrary to the spirit (and I believe the letter) of the JavaEE spec.
> The documentation on this capability is either hidden or missing.
> I was tasked with working out how to use the JBOSS tools to configure these values and have been unable to do so.
> I modified the quickstart helloworld example to accept a value using the @Resource annotation and attempted to set this value using jboss-cli.
> After several attempts to guess how to do this I modified the servlet to walk down the context tree.
> This servlet throws a NameNotFoundException when trying to list the bindings at:
> * java:comp/env
> * java:app/env
> * java:module/env
> I have written the servlet to perform this walk in the following contexts:
> * Ithe initial context
> * java:
> * java:jboss
> * java:comp
> * java:module
> * java:app
> * java:global
> java:global seems to be able to accept values added using jboss-cli (not surprising)
> java:comp, java:module and java:app seem to return some of the expected values (eg ModuleName and AppName) but throw the exception when trying to list entries under */env
> The initial context and java: seem to display the entries added through jboss-cli
> Adding a Deployment descriptor (web.xml), that provides values for these entries, results in no entries that are visible through jboss-cli or any of the contexts listed in the servlet.
> I then ran the following command through jboss-cli and restarted the app
> /profile=full/subsystem=naming/binding=\/java\:app\/jboss-as-helloworld-ear\/env\/GREETING_TEXT:add(binding-type="simple",value="RE")
> This resulted in the same NameNotFoundException being thrown at java:app/env when walking the initial context as has been thrown all along when listing env in java:app 
> It also resulted in java:app appearing in the java: context but being empty.
> Prior to running the add command, java:app did not appear in the initial context or java: context at all.
> I then ran the following command through jboss-cli and restarted the app
> /profile=full/subsystem=naming/binding=\/java\:module\/jboss-as-helloworld-ear\/jboss-as-helloworld\/env\/GREETING_TEXT:add(binding-type="simple",value="SJM")
> This resulted in the same NameNotFoundException being thrown at java:module/env when walking the initial context as has been thrown all along when listing env in java:module
> It also resulted in java:module appearing in the java: context but being empty.
> Prior to running the add command, java:module did not appear in the initial context or java: context at all.
> My conclusion is that my commands in jboss-cli may be the appropriate ones to add the correct entries but that the servlet cannot reach the java:module/env or java:app/env contexts that should be available to it according to the javaEE6 spec.
