Hi,
I am trying to get the .pdf file from the QUEUEA using the follwing MQGET Program

The Program is Below:

import com.ibm.mq.MQC;
import com.ibm.mq.MQEnvironment;
import com.ibm.mq.MQException;
import com.ibm.mq.MQMessage;
import com.ibm.mq.MQGetMessageOptions;
import com.ibm.mq.MQQueue;
import com.ibm.mq.MQQueueManager;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.util.ArrayList;
import java.util.Hashtable;
import java.io.IOException;

public class MQGET
{
public static void main(String args[])
{
MQGET get= new MQGET();
get.MQGET("C:\\qq >");
}
public void getq(String path)
{
String hostName = "10.111.43.16";
System.out.println("Host name is " + hostName);
String channel = "CHAN2";
System.out.println("Channel is " + channel);
String qManager = "TEST";
System.out.println("Qmanager is " + qManager);
String qName = "QUEUEA";
System.out.println("Qname is " + qName);
int portno = 1415;//"Enter the port here as integer";
try
{
MQEnvironment.properties.put(MQC.TRANSPORT_PROPERTY,MQC.TRANSPORT_MQSERIES_CLIENT);
MQEnvironment.hostname = hostName;
MQEnvironment.channel = channel;
MQEnvironment.port = portno;
System.out.println("Setting the qManager connection....");
MQQueueManager qMgr1 = new MQQueueManager(qManager);
System.out.println("Successful in setting the QManager connection");
int openOptions = 33;
MQQueue queue = qMgr1.accessQueue(qName, openOptions, qManager, null, null);
int depth = queue.getCurrentDepth();
if(depth == 0)
return;
MQMessage message = new MQMessage();
MQGetMessageOptions getOptions = new MQGetMessageOptions();
getOptions.options = 8192;
queue.get(message, getOptions);
int fnlen = message.readInt2();
String filename = message.readString(fnlen);
int size = message.readInt4();
byte buffer[] = new byte[size];
message.readFully(buffer, 0, size);
filename = filename + ".pdf";
File fi = new File(path, filename);
FileOutputStream fout = new FileOutputStream(fi);
fout.write(buffer);
fout.close();
}
catch(MQException mqe)
{
mqe.printStackTrace();
}
catch(IOException ioe)
{
ioe.printStackTrace();
}
}
}
