Fault Handling with periodic notification and infinite retry.

Question

Hi all,
I am invoking a database adapter to call a PL/SQL procedure and during maintenance window the database could be down for upto 4 hours. My requirement is to keep re-trying until the server comes back up but notify someone after every 4 hours.
The result I am getting is really weird. It re-retires to connect to the database two times and then calls the Java class, which sends me exactly 25 e-mails every time and then it finishes. No error in the OPMN log after it finishes.
Please look at the code below.
Thanks in advance!

My fault Condition:
<faultName xmlns:bpelx = "http://schemas.oracle.com/bpel/extension" name = "bpelx:remoteFault">
<condition>
<action ref = "ora-retry"/>
</condition>
</faultName>
The retry action:
<Action id = "ora-retry">
<retry>
<retryCount>2</retryCount>
<retryInterval>2</retryInterval>
<retryFailureAction ref = "send-notification-apps"/>
     </retry>
</Action>
The Java Action:
<Action id = "send-notification-apps">
<javaAction className = "com.utility.SendMail" defaultAction = "ora-terminate" propertySet = "send-notification-properties">
<returnValue value = "RETRY" ref = "ora-retry"/>
</javaAction>
</Action>
Here is the BPEL handleBPELFault method:
public String handleBPELFault(IFaultRecoveryContext iFaultRecoveryContext)
Map propMap = iFaultRecoveryContext.getProperties();
String returnVal = null;
this.counter++;
System.out.println("The counter value is " + counter);
if (propMap != null)
setFrom(getParameterValue((ArrayList) propMap.get("email_sender")));
setTo(getParameterValue((ArrayList) propMap.get("email_recipient")));
setSubject(getParameterValue((ArrayList) propMap.get("subject")) + iFaultRecoveryContext.getTitle());
this.setRetryFlag(getParameterValue((ArrayList) propMap.get("retryFlag")));
if (this.getRetryFlag() != null)
if (this.getRetryFlag().equalsIgnoreCase("true"))
returnVal = "RETRY";
StringBuilder sb = new StringBuilder();
sb.append("RETRY!!!!!!!!!");
sb.append("This is the title: " + iFaultRecoveryContext.getTitle() + " was successfully retried.\n");
sb.append("This is getMessage : " + iFaultRecoveryContext.getFault().getMessage() + " was successfully retried.\n");
sb.append("This the process Name : " + iFaultRecoveryContext.getProcessId().getProcessId());
setText(sb.toString());
else
returnVal = "RETHROW";
StringBuilder sb = new StringBuilder();
sb.append("RETHROW!!!!!!!!!");
sb.append("This is the title: " + iFaultRecoveryContext.getTitle() + " was successfully retried.\n");
sb.append("This is getMessage : " + iFaultRecoveryContext.getFault().getMessage() + " was successfully retried.\n");
sb.append("This the process Name : " + iFaultRecoveryContext.getProcessId().getProcessId());
setText(sb.toString());
setHost(getParameterValue((ArrayList) propMap.get("host")));
setPort(getParameterValue((ArrayList) propMap.get("port")));
this.setProps(convertMapToProperties(propMap));
send(); //Send the email
System.out.println("PROPERTIES: " + props);
System.out.println("THERETRY FLAG " + this.getRetryFlag());
System.out.println("This actually gets out!!" + returnVal);
return returnVal;
