[xmlblaster] questions about return value of update() method



Hi,everybody
	
	I want to use the xmlblaster as a mom in my work, and there is a publish/subscribe  scenario:
	There is a business logic which deals with the messages delivered from the	 xmlbalster server in the update method of the subscriber, if the business logic returns false, maybe there has some errors in the deliveryed messages, and must be redelivered from the xmlblaster server.
	
    I had read the source file(CbDeliveryConnection.java),and the return value is ignored.
	
	I want to add some redelivery controls in doSend method of CbDeliveryConnection.java just like this:
		if (-1==address.getRetries())
		{
			int iRetriesCounter = 0;
         	while (true)
         	{
         		rawReturnVal = cbDriver.sendUpdate(msgUnitRawArr);
         		if (rawReturnVal[0].equals(org.inforMessaging.util.enum.Constants.RET_OK)) break;
         		iRetriesCounter ++;
         		rawReturnVal = null;
         		
         		try { Thread.currentThread().sleep(address.getPingInterval()); } catch (Exception e) { } 
         	}
        }
        else
        {
         	for (int i=0; i<address.getRetries(); i++)
         	{
         		rawReturnVal = cbDriver.sendUpdate(msgUnitRawArr);
         		if (rawReturnVal[0].equals(org.inforMessaging.util.enum.Constants.RET_OK)) break;
         		rawReturnVal = null;
         		try { Thread.currentThread().sleep(address.getPingInterval()); } catch (Exception e) { } 
         	}
        }

	Is any problem in my changes to the whole xmlblaster project? any unknowable effect to other programs?
	
	Any help is appreciated.
	Thanks!
