Hello
Its nothing difficult in that.While getting the message cast it to file.Read file in bytes through FileInputStream and same bytes write in other file as FileOutputStream.Hope this will solve ur problem.If u could'nt understand I had pasted the code below.Kindly go through the same.I had written on test MQServer.
import java.io.*; //import classes for IO operation
import com.ibm.mq.*; //import classes for MQSeries
import java.util.*; //import class to store properties
import java.net.*;
public class MQReadTry
{
public static void main(String[] args) throws Exception
{
System.out.println("Hello World!");
String qmgrname=qmgrname;
String qname=qname;
try{
MQEnvironment.hostname = "192.16.20.18";
MQEnvironment.channel = "SVRCONN";
MQEnvironment.port = Integer.parseInt("1717");
MQQueueManager qmgr = new MQQueueManager(qmgrname);
int openOptions = MQC.MQOO_INPUT_AS_Q_DEF | MQC.MQOO_INQUIRE;
MQQueue que =qmgr.accessQueue(qname,openOptions,null,null,null);
int depth=que.getCurrentDepth();
int t_dep=depth;
System.out.println(depth);
MQMessage msg=new MQMessage();
// msg.writeString("This is test carried out by raj");
//String message=msg.readLine();
MQGetMessageOptions gmo = new MQGetMessageOptions();
//gmo.options=MQC.MQGMO_MSG_UNDER_CURSOR;
System.out.println("Error ********");
//File fo=new File("filepath");
//while(true)
//{
while(t_dep>0)
{
msg=new MQMessage();
gmo = new MQGetMessageOptions();
//gmo.options=MQC.MQGMO_BROWSE_FIRST;
System.out.println(t_dep);
que.get(msg,gmo);
String msg_str=msg.readLine();
System.out.println(msg_str);
File f=(File)msg.readObject();
String fname=f.getName();
int i=(int)f.length();
byte[] b=new byte[i];
FileInputStream fis=new FileInputStream(f);
fis.read(b,0,i);
FileOutputStream fos=new FileOutputStream(filepath,true);
fos.write(b,0,i);
fos.close();
//f.renameTo(fo);
//FileOutputStream fout=new FileO
System.out.println(fname);
//gmo.options=MQC.MQGMO_BROWSE_NEXT;
t_dep=t_dep-1;
}
//else
//break;
//t_dep--;
//}
qmgr.commit();
}catch(MQException mq){
System.out.println(mq.getMessage());
}
}
}

Thanks Raj!
I think a few other people have requested a sample program like this before, would be okay with me adding this to the software repository on this site? (crediting you as the author of course)

Apart from the fact that it does not compile, I do not think that this piece of code does what you expect.
You will find samples that dump the content of the message itself, the issue I have found is retrieving the MQMD (message descriptor) using the java classes. If anyone has a solution I am also interested.
