So is there any jBPM guy can answer my question? Is this the rude way is the
only way for this question? thanks.

The question is that I want to create a new ProcessInstance inside an outer
ProcessInstance, actually this creation (new) operation is done in the
ActionHandler of the outer ProcessInstance, the key is that the outer one is a
persisted one, but I don't want the inner one to be persisted. So I

Unfortunately, your hack doesn't work, I got a more serious exception:

Hi guys
I'm using JBPM 3.3.0.GA, I have a use case that want to create a new
ProcessInstance (name as A) inside an actionHandler of an outer one, the code
in the action handler would like this:
| @Override
| public void execute(ExecutionContext executionContext) throws Exception
{
|
OK, thanks Manik, I will try it later.

Hi guys, I wrote a test application to test passivation function with
JDBCCacheLoader, the application is simple, two threads, the writer thread try
to put 20 nodes into the cache and the reader thread do the read operation
periodically. I only set maxNodes to be 10 and passivation to be true,
BTW, i was using JDK1.6 and following is some log output:
2008-12-26 13:28:16,415 [Thread-1] DEBUG (AdjListJDBCCacheLoader.java:147) -
executing sql: select fqn from jbosscache where parent=? (/testRegion)
| 2008-12-26 13:28:16,509 [Thread-1] INFO (ReadThread.java:40) - currently

I think it shouldn't be a problem, I have tried JBossCache 3.0.1 (with the
embeded jgroup.jar) and successfully deployed it on a Weblogic cluster
enviroment with the default configuration.

It seems no body care about my problem :(
Anyway, I'm still doing the test and finally find that whenever I write the
following code in my run() method of the reader Thread, the reader has a big
chance to get null from a specific node which should have value, the code is:

Hi RS, I think you can try the TcpDelegatingCacheLoader. Although I didn't try
it yet, the behavior of this loader described in the user guide may be is the
one you want.
I quote some of the description in the user guide for this loader as below:

Hi
I have two cluster nodes, nodeA and nodeB deployed on WLS 10.3, the demo code
is very simple, I list the step is follow:
1. create a FQN using: Fqn.fromString(/testRegion);
2. create a Cache with default total-replication.xml configuration, and store
it in a servelet property, so all the
and
will pass in an Option to enable data gravitation on a per-invocation basis. If
autoDataGravitation is true this Option is unnecessary.
But do we have any chance to know if the cache miss is caused by server failure
or the data is not loaded before in the server?
