We need to support multiple versions of the same ear in a single JBoss instance. In our session bean, we inject a Spring bean: @Spring(jndiName="xyzBeanFactory-1.0", bean="manager") private Manager manager; This is okay as long as someone remembers to update the session bean by changing jndiName to a dfferent name (e.g. xyzBeanFactory-2.0) every time we release a newer version of the ear. Instead, we are wondering if jndiName can be dynamic, say get its value from an env-entry in ejb-jar.xml. This will allow us to make our build tool (maven2) to substitute the bean factory version in ejb-jar.xml before packaging the ear.
