-------------------------------------

Hi, 

Just tried the deployment with 
https://repository.apache.org/content/groups/snapshots/org/apache/openejb/apache-tomee/1.7.3-SNAPSHOT/apache-tomee-1.7.3-20150529.041110-32-plume.tar.gz

Many thanks for addressing the issue,
Kind regards,
Nuno.

> Hi,
> I am trying to experiement running an application of relative large size on tomcat ee.
The application deploys both to Glassfish 3.1.2.X and weblogic 12.1.2.  - Just to have a reference
point as to application compatibility.
> When deploying to tomee plume version 1.7.1 one of the problems I have encountered has
to do with the JNDI Naming contexts visible to the application during deployment. 
> Namely, the persistence.xml will be telling eclipse link to manage the generation of
new entity sequence numbers using a non JTA data source.
> For example,
>  <persistence-unit name="MY_PU" transaction-type="JTA">
>         <provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>
>         <jta-data-source>jdbc/JTA_DS</jta-data-source>
>         <jar-file>../some.jar</jar-file>    <------- this is the first
problem. Was forced to have the ../ added to the jar file
>        
>         <exclude-unlisted-classes>false</exclude-unlisted-classes>
>         <shared-cache-mode>DISABLE_SELECTIVE</shared-cache-mode>
>         <properties>            
>             <property name="eclipselink.logging.level" value="INFO" />
>             <property name="eclipselink.logging.level.sql" value="INFO" />    
       
>             <property name="eclipselink.logging.parameters" value="true" />
>             <property name="eclipselink.jdbc.sequence-connection-pool" value="true"
/>
>             <property name="eclipselink.jdbc.sequence-connection-pool.non-jta-data-source"
value="jdbc/NON_JTA_DS" />   <------------- Eclipse link will get a naming exception
here
>         </properties>
>     </persistence-unit>
> Ok.
> Now with the above "sample" persistence.xml in mind, what happens is the following.
> PROBLEM 1:
> The <jar-file> defitnition on the persistence.xml was forced to be tuned with ../
- whereas in weblogic and glassfish this was not necessary.
> The application is bundled in a War file that in the lib/ folder contians all the WAR
dependencies (ejbs and such). One of these jar files - let us call it my-main.jar is the one
that in the classes/META-INF/persistence.xml  holds the persistence.xml referring to all other
jars interesting in the /lib/ of the war file.
> Under Tomee this the search for the mentioned jar files that are relevant to the persistence
unit seems to bugy. Since tomee is blowing up with file not found exception:
> my-main.jar/some.jar 
> And of course he is right. The path he built to find the JAR was not correct and therefore
he could not fild the <jar-file>.
> Therefore, here I was forced to put in the <jar-file>../some.jar<jar-file>
> to overcome the file not found exception.
> PROBLEM 2:
> Now the second problem, this is a bit more important, is in the JNDI naming context themsevels.
> Using:
> tomee-webaccess-1.7.1/scripting
> And the following script:
> var pairs = ctx.lookup('java:openejb/Resource/jdbc').list('');  <----- This is key.
> while(pairs.hasMore()) {
>   println('[entry] ' + pairs.next().getName());
> }
> var user = ctx.lookup('java:comp/EJBContext').getCallerPrincipal().getName();
> println("Logged user: '" + user + "'");
> I am able to verify that the two data sources I defined in the tomee.xml are part of
the openejb Resource naming context.
> Which is OK. 
> So the list of names under jdbc/ shows me both the JTA_DS and the NON_JTA_DS.
> And indeed the @PersistenceContext inject for the JTA_DS seems to be working fine.
> But eclipse link will blow up when it tries to the JNDI lookup for jdbc/NON_JTA_DS as
listed in the following exception snippet.
> Internal Exception: javax.naming.NameNotFoundException: Name [jdbc/NON_JTA_DS] is not
bound in this Context. Unable to find [jdbc].

> To me this looks like a serious bug, but you will know better than me the standard itself
and the expectations that an application is allowed to have on the available naming contexts
in the container.
> But I was under the impression that regardless of the application module, the jdbc name
should always be visible at the root of the initial naming context.
> I am not sure if it will succeed or not, but for the time being I will try to work around
this issue by using the following JNDI name:
> java:openejb/Resource/jdbc/NON_JTA_DS
> Since i can use the scripting tool the validate that this name can bee lookedup.
> I am not satisfied with the solution - i think of it is a hammer pattern approach and
injection using the easy name : jdbc/NON_JTA_DS should just work.
> It works for weblogic and glassfish 3.1.2 at least so I would assume it should work as
well for tomee.
> Kindest regards,
> And thanks for the support.
