I finally figured out how to integrate with Tomcat without the need
for an explicit installer stage. With the latest code, you simply
copy the openejb.war into the Tomcat webapps directory. That's it.
When the openejb.war starts, it will boot OpenEJB and process any
already running applications. Processing application is pretty cool
now. We simply deploy any EJBs and persistence units embedded in the
application and resolve any of the unresolved JNDI references in the
application.
With the new system there are two cases where you still want to run
the installer:
1) If you have a servlet with load-on-startup _and_ this servlet uses
EJB or persistence units, you will need to run the installer to
assure that OpenEJB starts before the load-on-startup servlet is
created.
2) If you are on Java5 and using OpenJPA (the default JPA provider),
you will need to install the JavaAgent for anything but trivial JPA
clients. For example, the itests need the JavaAgent on Java5.
Basically, if you are on Java6 you most likely don't need to run the
installer, which makes using an IDE much easier. If you do want to
run the installer, just click the install button as before.
I updated the files in my home directory if you want to try it out
