Hi,
I have the following code to set the mcd and jms folder in an MQMessage:
| Code: |
private final static String MCD_FOLDER = "<mcd><Msd>xml</Msd><mcd>";
private final static String JMS_FOLDER = "<jms></jms>";
private void addRFH2(MQMessage theMsg) throws IOException
{
int mcdFolderLength = MQQueueWriter.MCD_FOLDER.length();
int jmsFolderLength = MQQueueWriter.JMS_FOLDER.length();
int mqStructLen = MQC.MQRFH_STRUC_LENGTH_FIXED_2 + mcdFolderLength + jmsFolderLength + 4 + 4;
theMsg.format = MQC.MQFMT_RF_HEADER_2; // Msg Format
theMsg.writeString(MQC.MQRFH_STRUC_ID); // StrucId
theMsg.writeInt4(MQC.MQRFH_VERSION_2); // Version
theMsg.writeInt4(mqStructLen); // StrucLength
theMsg.writeInt4(MQC.MQENC_NATIVE); // Encoding
theMsg.writeInt4(MQC.MQCCSI_DEFAULT); // CodedCharacterSetId
theMsg.writeString(MQC.MQFMT_STRING); // Format
theMsg.writeInt4(MQC.MQRFH_NO_FLAGS); // Flags
theMsg.writeInt4(1208); // NameValueCCSID = UTF-8
theMsg.writeInt4(mcdFolderLength);
theMsg.writeString(MQQueueWriter.MCD_FOLDER);
theMsg.writeInt4(jmsFolderLength);
theMsg.writeString(MQQueueWriter.JMS_FOLDER);
}
|
The line
| Code: |
| theMsg.writeString(MQC.MQFMT_STRING); // Format |
Is the problem - it's fine if I set it to
| Code: |
| theMsg.writeString(MQC.MQFMT_NONE); // Format |
Setting it to string is the problem.
I'm trying to get the WBI Adapter Framwork to accept Business Objects from a japa program. The working message that the Framework accept have the "Data Format" set to "MQSTR " if I view a working message with rfhutil.exe
Am I doing something obviously wrong ?

Is MCD_FOLDER a multiple of 4 characters. Is JMS_FOLDER a multiple of 4 characters.
Cheers,

You could actually be helpful by explaining instead of being sarcastic..
"There are no stupid questions...." I think you know the rest |

I really don't think you know whether EddieA was being sarastic or not. Just like you really don't know what tone or mood I'm in when I'm posting this response.
It looked to *me* like he was simply asking some basic questions.
And they seemed kind of helpful, as well. He told you to check to see if your MCD_FOLDER length was an even multiple of 4 bytes, and the same with the JMS_FOLDER. And a basic read through of the description of the RFH2 header would have *also* told you that.

Maybe an even more fundamental question:
a) you seem to be using base java to do this
Why worry and go to all the trouble when you could be doing it in a much easier way using the JMS classes for java ??
Enjoy    |

OK, sorry - maybe he wasn't being sarcastic at all - I'm just fustrated trying to get this to work - apologies.
I'm working on a project and MQ is only a tiny part of it and I honestly don't have time to sit down and read through the whole "Using MQ" pdf file - the development schedule has way too much other stuff on it - I looked at the part about RFH2 headers in the document and it talked about properties that could be set, but it wasn't obvious (to me) how to set these and since I've no experience of JMS either I didn't know how to set them.
In all honesty - I just want a plain English explanation of how to do this - the code I already posted was taken from an example off this forum and I assumed this was the way to go.
Gotta love IBM - working there and nobody there seems to have a clue about MQ and Java (in my dept, that is). |

Well Martin, using jms you do something like this:
//get the context javax.naming.InitialContext
//Hashtable or Properties (impl of hashtbl)
Properties props = new Properties();
// set properties for initial context factory
// set properties for provider url
// set referal to throw
//get the qcf
QueueConnectionFactory qcf = (QueueConnectionFactory) ctx.lookup("myqcf");
// alternatively use MQQConnectionFactory..... and set the props on it
//create queue connection
QueueConnection qcon = qcf.createQueueConnection();
//create session
QueueSession qs = qcon.createSession(true,Session.AUTO_ACKNOWLEDGE);
//get the q
Queue myqueue = (Queue) ctx.lookup("myqueue");
//alternative
//no qmgr specified will default to the one of the connection
myqueue = qs.createQueue("queue:///myqueuename"); //do not add targetClient=1 as this would suppress RFH header
//create sender
Sender sdr = qs.createSender(myqueue);
//create message
TextMessage tm = qs.createTextMessage();
tm.setText("this is the message body");
//set properties
tm.setProperty(.....); //check out the API. This goes into RFH header
//send
sdr.send(tm);
//cleanup
sdr.close();
qs.commit();// it was created transacted
qs.close();
qcon.close();
//done.
For the rest and the details read the manuals.
Enjoy |

OK - After coming in fresh today after the weekend - got this sorted.
It turned out to be a problem with the CodedCharacterSetId - I had it as MQCCSI_DEFAULT, but when I tried to set the format to MQFMT_STRING (changing from MQFMT_NONE) it gave an error.
It turned out that the CodedCharacterSetId had to be MQCCSI_INHERIT.
I found this out by examining the bytes set in my message header in Java, and the bytes in a valid message in a Hex editor.
My question is, however, why does it have to be set to MQCCSI_INHERIT ?
A search of the "Using Java" document returns no results for MQCCSI_INHERIT - is there some other document I should also have referred to find this out, instead of the way I had to find it out ?
For anyone interested - here's my code to set the RFH2 header :
| Code: |
private final static String MCD_FOLDER = "<mcd><Msd>xml </Msd></mcd>";
private final static String JMS_FOLDER = "<jms> </jms>";
public void addRFH2(MQMessage theMsg) throws IOException
{
int mcdFolderLength = MQQueueWriter.MCD_FOLDER.length();
int jmsFolderLength = MQQueueWriter.JMS_FOLDER.length();
int mqStructLen = MQC.MQRFH_STRUC_LENGTH_FIXED_2 + mcdFolderLength + jmsFolderLength + 4 + 4;
theMsg.format = MQC.MQFMT_RF_HEADER_2; // Msg Format
theMsg.writeString(MQC.MQRFH_STRUC_ID); // StrucId
theMsg.writeInt4(MQC.MQRFH_VERSION_2); // Version
theMsg.writeInt4(mqStructLen); // StrucLength
theMsg.writeInt4(MQC.MQENC_NATIVE); // Encoding
theMsg.writeInt4(MQC.MQCCSI_INHERIT); // CodedCharacterSetId
theMsg.writeString(MQC.MQFMT_STRING); // Format (content)
theMsg.writeInt4(MQC.MQRFH_NO_FLAGS); // Flags
theMsg.writeInt4(1208); // NameValueCCSID = UTF-8
theMsg.writeInt4(mcdFolderLength);
theMsg.writeString(MQQueueWriter.MCD_FOLDER);
theMsg.writeInt4(jmsFolderLength);
theMsg.writeString(MQQueueWriter.JMS_FOLDER);
}

The Application Programming Reference lists all the defined Data Types and MQ Constants.

MQCCSI_INHERIT means that the current header, the RFH2, has the same CCSID as the previous header.
MQCCSI_NONE means that the CCSID of the header is 0, which is invalid for an RFH2. |
