MQSeries.net :: View topic - Changing the TCPIPSERVERRECEIVE node length property

Hi;
I couldn't change the length property of the TCPIPSERVERRECEIVE node.
i'm using a java compute node to achive that but some thing must be wrong.The input message is a binary message with a 4 byte len of the message.
Here is the code :

.
.
.
MbElement BLOBel = inMessage.getRootElement().getLastChild().getFirstElementByPath("BLOB");

byte[] blobData = (byte[])BLOBel.getValue();

int msgLen = 0, pow =6, temp;
for (int i = 0; i < 4 ; i++)
{
temp = (int) blobData[i];
if (temp < 0)
temp += 256;
msgLen += temp * (16 ^ pow);
pow -= 2;
}

msgLen -= 4;

MbElement localEnv = contact admin.getLocalEnvironment(). getRootElement();
MbElement Tcpip_server = localEnv.getFirstElementByPath("TCPIP");
Tcpip_server.getFirstElementByPath("Receive").getFirstElementByPath("Length").setValue(msgLen);
.
.
.

the flow is some thing link this :

TCPIPServerInput------>Java_Compute-------------->TCPIPServerReceive -----------> ...
