JMS error - Failed to process message

Question

Hi everybody,
I got the following JMS exception during message processing. I do not really understand what the root cause:
sendMessage(Message) - Exception sending message in thread [0] : Failed to process message: Failed to add message=ID:b8591990-c1ab-1004-8625-3433a788d95f, destination=QueueName3 (5)

If someone has an idea, I would appreciate a lot!

No, Iam just storing a simple message say "Hello" in the queue, the message is stored in the queue but it is shown in the below format when I opened that file in Notepad:
UUªª ªªUU ‡ÿãÂ- ‡ 6›4•Z 6›4”öÿ Â
Ô£9™ÿÿ¬h ÎM o „      fÂ6›4”ñ Trial4 com.sun.messaging.BasicQueue Hai ªªUU
and soon Iam getting this error below:
[Fatal Error] :1:1: Content is not allowed in prolog.
JMSBC-E0713: Failed to process JMS message [com.stc.jmsjca.core.WTextMessageIn@1e377d5] in onMessage: Content is not allowed in prolog.
