aliases for resources injection

Hi all,
i'm using Glassfish 3.1 as application server for my EAR. To create the JMS and JDBC resources required by my application i have the glassfish-resource.xml file. These resources are created with application scope so when I inject them i have to use "java:app/" e.g. @Resource(mappedName="java:app/jms/myResource").
Is possible to create an alias so i don't have to prepend the "java:app"? What i want to do is @Resource(mappedName="jms/myResource").
I need this because i have to deploy my application also in Websphere 8. There i have to create the resources before deploying the application and therefore the scope is different.
The glassfish-ejb-jar.xml may help?

Matt.
