MQSeries.net :: View topic - Can not get the value from readString outside the method

The problem im having is that outside of the method that I get the message off the queue I can not get the string with readString. It will correctly give me the length but when i try to do a readstring(length) it throws the IOException error. Here is a sample of the code below. The queues are clustered

THIS IS THE METHOD CALL
public void call()
{
MQMessage msg = getOutQueue();
int temp = msg.getTotalMessageLength();
try
{
//this will not print the message and throws IOException
System.out.println("MSG ="+msg.readString(temp));
return theMessage;
}
catch(IOException e)
{}
}
THE ACTUAL METHOD and returns type MQMESSAGE
public MQMessage getOutQueue()
{
MQMessage theMessage = new MQMessage();
getSeqMO.options = MQC.MQGMO_FAIL_IF_QUIESCING | MQC.MQGMO_SYNCPOINT | MQC.MQGMO_WAIT;
getSeqMO.matchOptions = MQC.MQMO_MATCH_CORREL_ID;
theMessage.encoding = MQC.MQENC_NATIVE;
theMessage.characterSet = MQC.MQCCSI_Q_MGR;
theMessage.correlationId = seqNum.getBytes();
theMessage.messageId = seqNum.getBytes();
getSeqMO.waitInterval = getTime;
queue.get(theMessage, getSeqMO);
int length = theMessage.getTotalMessageLength();
String temp = theMessage.readString(length);
System.out.println(temp)//this will print correctly
return theMessage;
}

Thanks for any help
