Codebase setting and rmiregistry

Hi,

I'm reading up on RMI and tried the Java 5 RMI example over at Sun's web tutorial. Right now, two things remain unclaer to me:

1) At least for the tutorial, I started the RMI registry manually. How does the RMI registry work in conjunction with Tomcat or a full-fledged application server like Glassfish, JBoss or Websphere? My googling wasn't very successfull. So far I assume that each container automatically starts up a RMI registry, but how and when do I bind my objects, at application start up / deploy? Or is my assumption wrong anyway?

2) I admit that right now I don't understand Sun's note about the codebase. Is this a mandatory option/security policy one has to set? Are remote objects always downloaded to the client machine or is this an option?

LocateRegistry.createRegistry will create(start) an RMI registry programatically, so, it can be used if someone does not want to start it manually.

No a codebase is required only if you want to facilitate dynamic class downloading for clients. If your clients do not want to download any class definitions then this is not required.

Sorry for my late replay and thanks for your answer. Concerning my questions:

1) So in a webserver I might run a servlet to start/create a registry and bind my objects or is there a more standardized JEE way?

2) I understand it that dynamic code downloading as an alternative to handing out jar files with my own classes, right?
