I have a bit of a predicament with circular refrences in EJBs. Due to legacy reasons, I have two EJBs - each which references the other (and refactoring would be non-trivial). I would prefer to keep them local (as opposed to remote) for security reasons. Trouble is, I don't know how to deploy such an arrangement in geronimo. Each EJB will need to reference the other in openejb- jar.xml with an <ejb-ref> stanza. But since each one is dependent on the other, each one cannot be deployed before the other (as geronimo checks for the ejb reference at deploy time). Without violated some accepted principals of physics, that leads to an impossible situation. How could I go about solving this issue?
This is supposed to work easily, at least if the ejbs are in the same ear. Deployment goes in phases: in "initContext" we try to find out and "publish" all the things you could possibly reference, such as ejbs and datasources. Then in "addGBeans" we process the jndir ref info and construct the jndi References to the appropriate stuff. For ejbs in the same ear, all necessary info should have been "published" and thus available.
If you ejbs are in different ears, things get a bit trickier. IIRC you have to supply the entire abstract name of the ejb container gbean for at least one side of the relationship.
Are you speculating or have you actually run into a problem :-)? thanks david jencks
