How to stop the cluster node form leaving the Grid.

Question

Hi,
I am new to Oracle Coherence.
I used the following tutorial to get started with Coherence.
http://www.oracle.com/technology/pub/articles/vohra-coherence.html?msgid=6521631
Within JDev an Coherence instance is started, data is entered and queried.
Next I'd like to connect this to a running Coherence instance, (started with [java -jar coherence-home\lib\coherence.jar)
When I start the coherence from cmd and run the application from within JDev, I can see a connection is made
The log says as
2008-07-23 07:03:56.304 Oracle Coherence GE 3.3.1/389 <D5> (thread=Cluster, memb
er=1): Member(Id=2, Timestamp=2008-07-23 07:03:56.117, Address=64.181.243.150:80
89, MachineId=1686, Location=process:4548@SDCHS20I189) joined Cluster with senio
r member 1

er=1): Member 2 left Cluster with senior member 1
Is the leaving of node is pre defined. How to stop this. What changes has to be done in the config.xml file.
One more thing.I am not able to see the data i enter through the Jdev Application. To see the data i did the following
Map (?): cache DBBackedCache
2008-07-23 07:08:17.820 Oracle Coherence GE 3.3.1/389 <Info> (thread=main, membe

Hi Jona,
   Sometime Inner Events might cause this problem.
   While handling events avoid processing/handling inner events. pVal.InnerEvent is a boolean property that helps you to identify this issue. So I suggest you to use EVENT FILTERING, if you are not doing that.  Let me know if you still have issue.
   As Ad Kerremans said, you try to catch events by global  try catch.
