Deploying EJB to an existing application

Question

hi!
I've got an existing J2EE-application with many EJBs. Now I want to add 1 EJB to it.
If I deploy this EJB, the application.xml within the existing application ist replaced by the
application.xml of the deployed one. In this case, none of the old EJBs is startable.
The only possibility to get it to work, is to change the application.xml after deployment (insert all existing
<module> tags) or replacing the application.xml within the ear-file manually.
Is there a better way? (within an application of 10 EJBs this shouldn't be a problem, but in our case with more than 100 EJBs, it is tedious)

Answer 1

What I understand your posting that you have an existing application with say 10 EJBs and you overwrite the application.xml with new info about just the new EJBs. If you do so then application will lose the reference about the old EJBs and hence the old EJBs will not be available for use.
You can deploy the new EJBs in a separate application and use the parent attribute to make parent/child relation between applications.
The best way to redeploy is to package the EJBs in an EAR and redeploy the EAR. If your EAR is in $OC4J_HOME/j2ee/home/applications directory then replacing the EAR also redploys your application. You can use ant or tools like JDev to build your EAR.
