Synchronizing on Process Instance Object

Question

Hi,
We have a process web service, which is used to create, notify and update BPM process instances.
This process web service is accessed from Java code.
The java code uses a re-try mechanism to talk to the process web service.
We want this to be changed using wait-notify. But we have only the string value for Process Instance ID.
Can anybody help me on how could we get the BPM process instance object with the Process Instance ID?
I hope for this case we should synchronize on the BPM process Instance Object.
Please find below the current code snippet with re-try which needs to be changed as wait-notify.
for(int i = retryCount; i >= 0; i--) {
try {
sResult = wsClient.notifyUpdate(oEvent, oTG, sInstId);
break;
catch(Exception e) {
if(i == 0) {
throw e;
logger.error(getClass().getName() + " - Failed to call wsClient.notifyUpdate()");
try {
logger.info(getClass().getName() + " - Retrying bpmUpdateProcessInstance ... " + (retryCount - i + 1) + " times in "
+ (System.currentTimeMillis() - startTimeMillis) + " millis.");
Thread.sleep(retryInterval);      
catch(InterruptedException ignore) {
     //silent catch is fine here
}// end for loop

Hi,
Please correct me if I miss-understood your question.
You want to know the process instance Id of a particular BPM process ?
You want to do it through java code or in BPM process layer ?
Which version of OBPM/ALBPM you are using ?
