Message header problem

[venkat]

Hi,

Host server is not processing the messages which are sending by my
client environment, due to missing the header value in message.

I am sending "0200" type messages.I have configured messages as xml
files and placed in data\AGENT folder.
I have configured Base24Channel and Base24Packager in channel.xml file
and placed in deploy folder at client side.
And using XMLPackager in client program to unpack the xml configured
message to ISOMsg.

Can any body tell, how to set the header content in message and what
could be the header contents ?
Is message header varies by message type or channel type ?



Thank you
Venkat.

Are you setting a header value?

isomsg.setHeader(value)

For the contents you will need to check with the administrators of the
system you are connecting to.

Have you got the Programmers Guide yet? It will help you to solve this
sort of 'problem'.

See above, it could be either or both.

I am not setting header value.

   I have tried to set header content by using API method from ISOMsg class as you given here.
  
   String headerValule = "0000006F";
   BaseHeader header = new BaseHeader(headerValule.getBytes());
   m.setHeader(header);

   I have understood that header value contains the message length. So i have calculated message length by adding all fields lengths and setting its   hexa value(0000006F) as header. Please correct me if mu understanding is wrong.
Host server is throwing following error

What system is your target host/server?

In your reply below is based on jPOS, are you in control of both the
client and the server?

Do both ends know about the header?

Is there another different host, with documentation?

Does this header format and content match the needs of your target host
system specification?

No, the header is distinct from the length of the message (which is
taken care of by the Channel), the Header usually follows the length and
precedes the message on the wire (Section 2.3 in guide)

It is wrong, the Channel calculates and handles any length for you.

Please consider the length as distinct from the header, if it only a
length you need, simply choose or create the right Channel.

This server's Channel perhaps doesn't know about the header, how is it
setup/configured?

Is this a test server in place of a 'real' target host?

If there is a 'real' target host, have you confirmed the header format
expected with the owners?

It is there (Section 2.3, Chapter 6) and scattered through, I would hope
with enough detail to get you going. Certainly there have been numerous
previous discussions on this list too.

Which version of the guide do you have?
