    EJB deployment

      Hello!

      Sorry, I am just starting to read Marc's JMX book but I have actually a question about deploying regular EJBs. When I do a total redeploy or when I restart Jboss, how do I make sure the jars and therefore the beans are deployed in the right order by Jboss? For instance if a jar references another jar, this referenced jar has to be deployed first. Maybe I am also missing something. Let me know?

      Thanks for your answer, I don't know if this question is posted in the right category.

          Not sure about the answer. You did not mention the version you use and I get mixed up on differences in versions. I think things are deployed in alphabetical order so you can naming the jars as is appropriate. In later versions, I think JBoss is smart enough to read in a jar and withhold final deployment until dependent jars are loaded. Since JBoss is so easy to start and stop, just try it and see what happens and search on your jar name in log file.

            Thanks for the answer, yes I should have said that I am using JBoss3.0.0
            It looks like jboss is smart enough to load entities before sessions beans when they are in different jars, but when it is a session bean jar referencing another session bean jar It doesnt work. I have to reload them manually.

              It :-)

              There are a number of ways to do this.

              1) Specify a in jboss.xml
              You have to find the jmx name of the bean or
              jar package. These are in the jboss.j2ee domain
              at
              http://localhost:8082 or http://localhost:8080/jmx-console

              2) Use the PrefixDeploymentComparator in jboss-service.xml
              I think this might be broken in 3.0.0?
              This allows you to name your beans for ordering
              10beanb.jar
              20beana.jar

              3) Write an MBean to deploy your beans,
              using a JMX invocation on
              jboss.system:service=MainDeployer deploy(URL)

              There are other mechanisms.
