Coherence in SOA BPEL Java Embedding error

Question

I am trying to use Coherence to cache message in SOA BPEL process.
The BPEL process is deployed into WebLogic 10.3.2 on SOA 11g platform.
Withing the BPEL, I use Java Embedding, try to cache a meesage on another coherence instance (Running as a server from
a different JVM). But I am getting "Storage is not configured" exception after the "Jave Embedding invoked" message.
Here is my code:
System.out.println("Jave Embedding invoked");
try{
//set localstorage to false, use remote Coherence server
System.setProperty("tangosol.coherence.distributed.localstorage", "false");
System.setProperty("tangosol.coherence.log.level", "3");
catch(Exception e) {
e.printStackTrace();
CacheFactory.ensureCluster();
NamedCache myCache = CacheFactory.getCache("mycache");
// put key, value pair into the cache.
myCache.put("Name","Test");
System.out.println("Value in cache is " + myCache.get("Name"));
I use the same code in JDeveloper, and see the message is put on the remote cache server. But when I invoke it through BPEL, I don't even see the new coherence member join the cluster.
I use the default cache-server.cmd from Coherence package to start the server.
Anyone has similar experience to share?
Thanks

Answer 1

Brian,
Thanks for the reply. For your questions:
1. A firewall between your process and the rest of the cluster.
I run Weblogic and Coherence server on the same development laptop, so no firewall here.
2. Mis/different configuration between your process and the cluster.
I did not use any customized configuration files, all configs are straight from coherence.jar.
3. A classloader issue leading to the wrong cache configuration being picked up.
Since I use the same jar in Coherence server and weblogic server, and confgurations are from the jar, so they are the same.
4. Using different and incompatible versions of Coherence between your process and the cluster.
See answer to 3.
I do not see the process from BPEL join the coherence server from the server console.
I am wondering if Weblogic server block coherence multicast messages, if that's the case, what other choices I can have to communicate to coherence server? is Coherence-extend the right direction to explore?
Thanks
George
