Please make sure you're working with the latest release - OpenEJB 0.8.1 (that's downloadable release from the site) or OpenEJB 0.8.2 (unofficial release, which you could build checking out the sources from CVS). > > 1.

If you run OpenEJB as a standalone server - OpenEJB Remote or CORBA server - you would need to specify the required properties to point your client (i.e. servlet, another EJB, VB app) to the server instance. The server runs in its own JVM hanling remote requests. That's where an IP address needs to be specified. There's also another way to run OpenEJB - the Local Server (mode). In this configuration OpenEJB runs embedded within an application, being its integral part. Noone, but the application can access that OpenEJB instance. That's like using another class in a package - in this case, however, the package is named OpenEJB :-) Read more at http://openejb.sourceforge.net/embedded.html and http://openejb.sourceforge.net/remote-server.html. CORBA mode is not yet described fully. If you need the description, tell us and it'll be written (just for you :-)). > > 3. I would like to understand the source code.

I'd suggest starting from the batch files (the very early starting point is openejb.bat) where you'd see how the modes are booted up. Should you have any questions, don't hesitate to ask. I also come across the same questions, but since I have started two or three weeks earlier I already received some of the answers and thus may answer yours. > > Regards, > Partha. -Jacek ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf _______________________________________________ http://OpenEJB.sf.net OpenEJB-user mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/openejb-user
