Error while invoking an asynchronous BPEL process

Question

Hi ,
I am trying to call an asynchronous BPEL process through java client.
Following is the code which I got from SOA bpel samples present in the following location
<SOA_HOME>\bpel\samples\tutorials\102.InvokingProcesses\rmi\com\otn\samples\async
The code fails while registering the callback
String convId = GUIDGenerator.generateGUID();
nm.setProperty(NormalizedMessage.CONVERSATION_ID, convId);
deliveryService.post("HelloWorld", "initiate", nm);
// register the callback
watchdog.registerAsyncCallback(convId, testAsyncHandler,
locator.getDomainAuth());
The error says java.lang.NoClassDefFoundError: org/collaxa/thirdparty/json/JSONString
I tried to search for this in google. But it seems noone has got this error or maybe noone has used this at all.
Maybe I am missing some jar file, but I am unable locate that.
Can someone help me in this please.

Hi,
These sort of class not found errors come when you are running from a client which does not have all the jar files requried to invoke BPEL using the client API.
org/collaxa/thirdparty/json/JSONString is orabpel-thirdparty.jar.
The complete list of Jar files you would need in the classpath are:
ejb.jar ($ORACLE_HOME/home/lib)
oc4j-internal.jar ($ORACLE_HOME/home/lib)
optic.jar ($ORACLE_HOME/opmn/lib)
orabpel-common.jar ($ORACLE_HOME/bpel/lib)
orabpel-thirdparty.jar ($ORACLE_HOME/bpel/lib)
orabpel.jar ($ORACLE_HOME/bpel/lib)
Hope this helps,
