Hi,
I am new to this technology. Can any one help me?
I am trying to read a message from Queue using MQMessage.readUTF() method. I am using base java and queue is opened using option MQC.MQOO_INPUT_SHARED.I am using default get message options.
The Exception i have received when i am trying to get the message content using MQMessage.readUTF() is
"An IOException occured whilst writing to the message buffer: java.io.EOFException"
But MQMessage.readLine() is working fine.
Thanks in advance

| Did you write your message using writeUTF? The UTF methods have a length at the front of the data. |

Yes i am using the MQMessage.writeUTF() method to write the whole string content of a file.
Here is my writeQueue code
| Code: |
MQMessage msg = new MQMessage();
msg.writeUTF(freader.getFileContent("C:\\input\\CLEAN_AP010_INPUT1A.txt")); |
freader.getFileContent(String ) method is reading String content of a file. |

There is NO length parameter in the writeUTF() method.
The signature is like that
| Code: |
| public void writeUTF(String str) throws IOException; |
can any one help? |

From the Using Java manual:
| Quote: |
| The writeUTF() method of MQMessage automatically encodes the length of the string as well as the Unicode bytes it contains. When your message will be read by another Java program (using readUTF()), this is the simplest way to send string information. |
How big is your file? I believe the limit of a UTF message is 64K. |
