Error serializing objectjava.io.UTFDataFormatException --Urgent

Question

Hi,
          I am getting the following exception from JMS. I am trying to send Object
          Message to JMS queue. The object message is created reading from XML.
          I figured out one block in XML which is causing this exception. However,
          there is no such character in that block which could be causing the problem.
          All classes in the object are serializable. Even I tried replacing that
          block of XML from a working XML. Still getting the same error. Any help or
          clue will be appreciated.
          Thanks in Advance,
          Rishi

Answer 1

If this is a production issue, I highly recommend contacting customer support.
          This is
          an informal forum. As to the exception on setObject, the code I inserted below
          is the same code that 5.1 setObject uses, so if one throws and exception and the
          other doesn't,
          I'm stumped.
