Hi. I'm looking for advice on how to use multiple EJB JAR files within a Seam application running with JBoss Embeddable EJB 3.0. The problem relates to EJB JNDI locations and how Seam discovers the EJB components. I have several libraries of JavaBean and EJB3 Seam components. Each library lives in it's own JAR file. This works fine in JBoss AS but I'm having trouble using multiple JARs with JBoss Embeddable EJB 3.0. I know that my application works fine if all the beans are in the same classpath / JAR file. However when I rebuild and run the app with multiple JARs Seam does not pick up the EJBs in the JARs that are not the main/home JAR. I can see that the EJBs have been deployed properly by the container and that the problem is that Seam is looking in the wrong place for the EJBs in other JARs. What is the best way to tell Seam to look in different JNDI locations when EJBs are deployed in multiple JARs? Here is a snapshot of my JNDI tree when the EJBs are deployed in *separate* JARs. There are two 'JARs', one named 'project' and the other named 'templating-ejb'.
