Class not found in META-INF/lib after deployment on Glassfish although all jars are there

Question

I'm facing the following problem: While deploying an eclipse ejb-project to my glassfish server, I'm getting a "Class [ ... ] not found" in my server's log for one of my beans. Therefore, Eclipse tells me that "deploy is failing".

The definitive cause for that error is that I'm using a class from a 3rd party jar (Apache Shiro). While/after the deployment, glassfish is not able to find the used class. If I skip the one and only line of code using the class from Apache shiro, everything works fine.

I use maven for dependency management and correctly added the maven dependencies to my Java build path (so I do not face any errors while implementing the code) and to my EJB deployment assembly.

The maven dependencies (all needed jars) are correctly packeted in my ejb-jar-file underneath META-INF/lib. This was double checked (1) by exporting and inspecting the ejb-jar-file by an Eclipse export and (2) by analysing the files on the glassfish server. All Apache shiro jars are fully deployed under domain1/eclipseApps/My-App-root/META-INF/lib (I also tried META-INF/classes with same error).

By the way: When I added the Apache shiro jars under domain1/lib, everything worked fine.

Thus, I assume that there is something wrong with my classpath so that glassfish is not able to find the jars under /META-INF/lib.

I am using Eclipse Mars.2 (4.5.2), Glassfish 4.1, Java (JDK) 1.8.0_25

Question: Why is my glassfish server not able to find the jars deployed to META-INF/lib for my ejb-project and, subsequently, isn't able to find the class used from an Apache shiro's jar file?

A ejb-project cannot include additional jars, if you need Then, you will need a ear-project that includes both your ejb-project as third-party libraries

ear-project + ejb-project + apache-shiro
