Dear Bela Ban. It's pleased to see your reply. I commented in the middle of your message and there is also my questions.

How would you integrate the two ? > First of all, this pilot-test is just for solving some weird project's requirement and my project specific. Yes, Erlang is a language as Java. And OTP is a runtime somewhat similar to OTP. And erl.exe is java.exe in the Erlang world. I plan to launch separate process of "erl.exe" and custom made Erlang application at the JBoss startup stage. And the JInterface(which is half Erlang, and half Java library) will the medium between JVM and Erlang-VM.

But I think this is good, because I got paid for this job, which requires firm understanding of JBoss and JavaGroups. So I am going to keep inspecting the current JBoss and JavaGroups and seeking bad smells and contributing the patch-codes. I think I could post some patch that removing some direct reference to "Implementations (ie. JChannel)" rather than "Interface (Channel)" > > > -- > And finally, I'm not sure that this is the right place to have this kind of discussion though. I want to ask about JavaGroups not JBoss. According to my memory, you are the one who created the JavaGroups and the first version you did was a Ensemble (for ML) implementation, right? Wasn't there any issue like I have? Did ML/Ensemble seamlessly integrate with Java? > Bela Ban > http://www.javagroups.com > Cell: (408) 316-4459 > > > > > ------------------------------------------------------- > This SF.Net email sponsored by: Free pre-built ASP.NET sites including > Data Reports, E-commerce, Portals, and Forums are available now. > Download today and enter to win an XBOX or Visual Studio .NET. > http://aspnet.click- > url.com/go/psa00100003ave/direct;at.aspnet_072303_01/01 > _______________________________________________ > JBoss-Development mailing list > [EMAIL PROTECTED] > https://lists.sourceforge.net/lists/listinfo/jboss-development ------------------------------------------------------- This SF.Net email sponsored by: Free pre-built ASP.NET sites including Data Reports, E-commerce, Portals, and Forums are available now.
