1. Re: Multiple JVM ESB instances communication
noel.rocher Mar 31, 2008 4:44 AM (in response to dsun)Hi,
The way it works : invocation will ask the registry which EPRs are available for a category/service. Then choose one and send him the message. No matter where the endpoint is located (in the same JVM or in another one). -

1 We have multiple ESBs running in their own JVM on one Physical box. We want to have one EPR invoke a remote EPR in different JVM, is it possible?
Yes, the only requirement would be that they share the registry configuration, i.e. that the local jUDDI instances use the same database."dsun" wrote:
2 if we have multiple ESBs running within one JVM, is there any document showing how to enable the communication among EPRs ?
If you mean multiple services then it would be done automatically through the registry.
It is no possible to have multiple ESBs within the same JVM at present, there is no mechanism for providing the isolation. This is something that will be fixed in the next major release, ESB 5. -

4. Re: Multiple JVM ESB instances communication
dsun Mar 31, 2008 11:35 AM (in response to dsun)I currently drop in A.esb and B.esb into deploy folder, and then use [run -c default] to kick off JVM. That what I mean multiple ESBs within one JVM. In this case, can we use the same solution, i.e. share the registry configuration?

kconner Mar 31, 2008 1:50 PM (in response to dsun)Yes, you can deploy multiple .esb artifacts into a single ESB VM. It is not necessary to make any configuration changes if you wish to do this.

6. Re: Multiple JVM ESB instances communication
dsun Mar 31, 2008 2:44 PM (in response to dsun)I have successfully tested to have multiple *.esbs within one ESB JVM to invoke each other based on Registry and Courier API.
I am about to test Remote EPR communication among multiple JVMs. Should I simply have multiple servers in multiple JVMs share the same data folder? Will there be a conflic when 2 ESB try to write to the same jUDDI database?
