openOptions = MQC.MQOO_INPUT_AS_Q_DEF + MQC.MQOO_FAIL_IF_QUIESCING;
mqQueue = mqManager.accessQueue(queueName, openOptions, null, null, null);
do
{
myMessage = new MQMessage();
try
{
MQGetMessageOptions gmo = new MQGetMessageOptions();
gmo.matchOptions = MQC.MQMO_NONE;
gmo.waitInterval = 30000;
mqQueue.get(myMessage,gmo);
msgText = myMessage.readUTF();
here i am getting the problem.It is giving an exception
java.io.EOFException
at java.io.DataInputStream.readFully(DataInputStream.java:268)
at java.io.DataInputStream.readUTF(DataInputStream.java:639)

Hi gopal reddy,
Try this
| Code: |
| String msgString = inMsg.readString(inMsg.getMessageLength()); |
instead of
| Code: |
| msgText = myMessage.readUTF(); |
If still dosen't work, i would suggest downloading some of the sample code available on this forum.
Regards. |

Are you certain that the message is in this format. readUTF() expects that the message starts with a 2 byte count.
Cheers,

i should use only the following statement
msgText = myMessage.readUTF();
b'coz i am receiving this message through MDB.In that i have only this option to read a message.
If anyone has a solution plz help me.
I am sending an MQMessage where the MDB will receive that message.I need to cast that message to MQMessage.can anyone help me with the sample code |

Completely wrong. Back to the drawing board. Even a cast to MQMessage will not give you base java but the JMS implementation.... If you use an MDB you will HAVE to learn how to use JMS.

Read the comment above and answer some simple questions:
What is the format of the message (MQSTR)? What is the content of the message(writeUTF)? How was the message sent(from java, jms or other app)?
Enjoy

MQMessage consists of xml data which is packed as string and sent using writeUTF().
In MDB i am able to receive this message by casting it to JMSBytesMessage.But some times it works fine and sometimes it is sending a null message along with the original message.
I went through the IBM site and they have mentioned that it is a bug in MQ(using writeUTF() and writeUTF()) and they have given a fix pack which is not of .exe but it is ibm-axpvms-wmq0530_eco08-v0100--4.pcsi. i do not know what to do with this one and they have not mentioned anything abt that in the site
plz help me out

Can you paste the link for this fix? The axpvms part of the name makes it sound like OpenVMS.. Since you are looking for an .exe file, I suspect you are on windows .....
