HI Team,
Kindly help..
I'm sending an .xls file content to MQ by creating object message using JMS style from .Net but at MQ the content is having some invalid headers and special chars.
Logic used to send
1. Read .xls file contents in byte array
2. Created objectmessage
3. Sending objectmessage to MQ from .Net application using JMS style
on doing so, after sending the message to MQ.. having invalid headers and special characters.
Thanks, Hamsa |

What problem character etc?
Care to give us a sample of what you get and what should be output?

Every time you reinvent the wheel the more square it gets (anon). If in doubt think and investigate before you ask silly questions. |

//connection
//CreateQueue
destination = sessionWMQ.CreateQueue(destinationName);
destination.SetIntProperty(XMS.WMQ_Target_CLIENT,1);
destination.SetIntPropert(XMS.WMQ_Target_CLIENT,XMSC.WMQ_TARGET_DEST_WMQ)
//create object message
objmesg = sessionWMQ.CreateObjectMessage();
//createProducer
//Read the number of files
string[] files = Directory.GetFiles(@"c:\...some path");
foreach(string filename in files)
{
byte[] file = system.IO.File.ReadAllBytes(filename);
var filenamec = Path.GetFileName(filename);
var MSGID = new byte[124];
var filenames = system.Text.Encoding.UT8.GetBytes(filenamec);
System.Buffer.BlockCopy(filenames,0,MSGID,0,filenames.Length);
objmesg.JMSMessageID = filename;
objmesg.JMSPriority =9;
objmesg.JMSTimestamp = DateTime.Now.Ticks;
objmesg.JMSRedelivered = false;
objmesg.JMSDeliveryMode = IBM.XMS.DeliveryMode.Persistent;
objmesg.SetObjectProperty("JMS_IBM_Last_Msg_In_Group", true);
objmesg.SetobjectProperty("FILENAME", Sample.xls);
objmesg.object = file;
producer.send(objmesg);
}
Here after executing above code the file will be sent to MQ and
input file contains some data like ABCDEF
Output wil be in some headers and special chars
ÿÿÿÿK%PK!ª÷X¤z[Content_Types].xml ¢( ÌTÉjÃ0½úF×+I¡”'‡.Ç6ôkl‹Ø’ÐLÒäï;vJÈ‚i ½ØØÒ¼e†yƒÑª*£%4Î&¢wE6uÚØ<ŸÓ·Î£■”Õªt±£áíÍ`ºö■W[LDA䟤Ĵ■Jaì<X>É\¨ñgÈ¥Wé\å ûÝîƒL%°Ô¡C/©EIÑëŠo”ÌŒÑóæ^M•å}iRE,T.> é¸,3)h—.*†ŽÑP

Kindly help how I can overcome unwanted headers and special chars.
Thanks |

Is this line:
| Code: |
var filenames = system.Text.Encoding.UT8.GetBytes(filenamec);
|
mistyped, and should have been:
| Code: |
var filenames = system.Text.Encoding.UTF8.GetBytes(filenamec);
|
I would recommend looking into what is happening here. I am not a .Net programmer, but my guess is that an assumption is being made here on what codepage the file is in and then being used to convert the file contents to UTF-8. For example, that method might be assuming (since you are not explicitly stating it) that the file is UTF-16 encoded and then reading the bytes as if they were UTF-16 and converting them to UTF-8. If the file was not UTF-16 encoded, that would be a problem and could lead to scrambled data.

Just a few crazy things:
| Code: |
| objmesg.JMSMessageID = filename; |
If we've said a hundred times it still does not seem to hit conciousness.
The message ID is NOT a String but a byte[24].
Typically JMS does not allow you to set the messageID.
| Code: |
| objmesg.SetObjectProperty("JMS_IBM_Last_Msg_In_Group", true); |
Not necessary if you are not explicitely doing grouping...
| Code: |
| objmesg.SetobjectProperty("FILENAME", Sample.xls); |
?? should that not be
| Code: |
| objmesg.SetStringProperty("FILENAME", "Sample.xls"); |
| Code: |
| objmesg.object = file; |
you might want to use a variable with a different name to avoid confusion between the File class and the byte[] you are effectevely supplying here.
Finally as you are using message properties be ready to deal with an RFH2 at the receiving end or make sure that the GMO(Get Message Options) include properties in handle...
Have fun
