well i have downloaded one from net:

package nbo.mqseries;

import com.ibm.mq.MQC;
import com.ibm.mq.MQQueueManager;
import com.ibm.mq.MQQueue;
import com.ibm.mq.MQMessage;
import com.ibm.mq.MQPutMessageOptions;
import com.ibm.mq.MQException;

import java.io.File;
import java.io.FileInputStream;

class FileTransfer
{

public static void main(String[] args)

{

String lFileName = args[0] ;
String lQName = args[1] ;
String lQMName = args[2] ;

System.err.println( "File name ........... : " + lFileName );
System.err.println( "Queue name .......... : " + lQName );
System.err.println( "Queue manager name .. : " + lQMName );

try
{
// Open input file
File lFile = new File(lFileName);
FileInputStream lFileInput = new FileInputStream(lFile);

// Connect to queue manager
MQException.log = null;
MQQueueManager lQM = new MQQueueManager(lQMName);

// Open target queue
MQQueue lQueue = lQM.accessQueue(lQName, MQC.MQOO_OUTPUT);

// Create message
MQMessage lMessage = new MQMessage();
lMessage.format = MQC.MQFMT_STRING;
lMessage.persistence=MQC.MQPER_PERSISTENT;

// Write file to message
String lShortFileName = lFile.getName();
lMessage.writeInt(lShortFileName.length());
lMessage.writeString(lShortFileName);
int lCharacter = 0;
while ((lCharacter = lFileInput.read()) != -1)
{
lMessage.write(lCharacter);
}
System.out.println("Message read");
// Send message
MQPutMessageOptions lPMO = new MQPutMessageOptions();
lPMO.options = MQC.MQPMO_NEW_MSG_ID;
System.out.println("Putting Message on queue");
lQueue.put(lMessage,lPMO);
System.out.println("Message put on queue");
// Close queue
lQueue.close();

// Disconnect from queue manager
lQM.disconnect();

// Close file
lFileInput.close();
}
catch(MQException e)
{
System.err.println("MQ Series error: cc=" + e.completionCode + ", reason=" + e.reasonCode);
e.printStackTrace();
}
catch(Exception e)
{
e.printStackTrace();
}
}
}
