    <p>The link @Peter gave you almost solves your problem. (<a href="https://stackoverflow.com/questions/5681197/access-a-local-session-bean-from-another-ear">link</a>)</p> <p>One trick which needs to be done to solve @Xavier's problem is to provide common.jar to both ears in the same version (loaded by the same class loader). If you do it, the class cast exception will not be thrown and you will be able to use the ejb with local interface.</p> <p>To do it you need to put common.jar into glassfish/domains/domain1/lib folder (substitute domain1 with you domain name). This way this jar will be loaded by a Glassfish's shared class loader.</p> <p>I made a quick test with Eclipse and Glassfish 3 with following structure:</p> <pre><code>package com.example; JarShared - @Local class Server EarServer - EjbServer - @Stateless class ServerBean implements Server EarClient - EjbClient - @Stateless @LocalBean class ClientBean </code></pre> <p>Lookup from ClientBean:</p> <pre><code>InitialContext ic = new InitialContext(); Server server = (Server) ic. lookup("java:global/EarServer/EjbServer/ServerBean!com.example.Server"); </code></pre> <p>I did not get ClassCastException and I could call sample method from ServerBean.</p> <p>Important notes:</p> <ul> <li>both EarServer and EarClient should not contain JarShared in lib folder, they should reuse the one which is in domains lib folder</li> <li>remember to restart Glassfish after adding JarShared to it.</li> <li>to make both ejb projects compile you must add JarShared to their build paths, but nothing more</li> </ul> <p>If you have questions, post a comment.</p>

    1. COHi, thank you very much for your response. I think they key thing you mention here is the domains/lib folder. I think previously, I was attempting to use the domains/lib/applibs folder, but can see how that will be a problem. I will attempt this solution today, and report/vote back :-) Thank you! :)

    2. COI did some testing, and read your post again :) I see you used glassfish 3.1 :) I think I'm picking up a trend here that glassfish 3 added support for this, and I'm on a wild goose chase on glassfish 2.1 :/ Sadly I cannot change to glassfish 3.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
