EJB programming & troubleshooting: Is resource-ref tag required?

  1. Is resource-ref tag required? (2 messages)

    In our application, we use JDBC to access database. The entity beans share the same database connections as other plain java classes. In such case, do I need to specify <resource-ref> tag in ejb-jar.xml and give the res-ref-name? Thanks.

    If EJB refer or use any resources (DS or other EJB), you need to specify the resource ref tag.

    You do not need the resource-ref tag as in the end you can always use the components full JNDI name to look it up.

    The resource-ref was to support the whole programmer/deployer separation. Of course most times this is the same person and is generally overkill.
