I'm going to communicate with Base24 BIC interface (1987 standard) and
I need to add a header  to ISO message .

Header = "ISO 020000011"

Rest is primary bit map and data elements . So could some one kindly
tell me a way to add above header to ISO message.

Many Thanks.

Thanks Chhil ,

I used ISOMessage.setHeader() method to add a header to ISO message

// Code

 String header="ISO010100011";

   byte[] bytearray=header.getBytes();

   m.setHeader(bytearray);

// End code

but when i see message at a log I can message header as
<header>49534F303130313030303131</header> .It is obvious that I can
see it in that way . But I want to send header as a String
( ISO010100011 ) . So is there a any way to handle the header in that
way. Kindly assist me .

Many Thanks.

I believe the data being sent on the wire be fine....this is the data that
is being printed and if you look at the code of Baseheaderthe dump is doing
a hexstring of the header else you wont see the special unprintable chars...

  public void dump (PrintStream p, String indent) {
        if (header != null) {
            p.println (
                indent
              + "<header>" + ISOUtil.hexString (header) + "</header>"
            );
        }
    }

I got to know that we can set a header to the channel as a example

new NCCChannel(server,port,packager,header) but some channels are not
supported and I'm using BASE24TCPChannel which is also not supported.
is it same with  ISOMessage.setHeader()  or what is the difference .

Many Thanks,
Suranga.

The header on the Channel would be the place to specify one that is
fixed for the life of the channel.

The ISOMsg could be given a header, but especially when the header
varies for each message.

If you have a header that never varies, you can hope your chosen Channel
takes a header in on it's constructor (or modify it to).

The BaseChannel class checks for a specific ISOMsg.header and use it, if
not it will use the Channel.header - if one is present.

BaseChannel.setOverrideHeader(true) could be used to reverse the
precedence ISOMsg.header has over Channel.header.

One thing I want to know is

Before sending a message through a channel is it necessary to add
packager and pack the message or what is the purpose. Because after
set packager and pack the message I can only see bit map on message
logger (I have already uncommented the entries in dump method  ) Kidly
advice.

methods
--------------
ISOMsg.setPackager();
ISOMsg.pack();

Sample OutPut
-----------------------
<isomsg>
  <header>49534F303031313031313534</header>
  <field id="0" value="0800"/>
  <field id="bitmap" value="{7, 11, 33, 70, 94}" type="bitmap"/>
  <field id="7" value="123"/>
  <field id="11" value="123"/>
  <field id="33" value="123"/>
  <field id="70" value="123"/>
  <field id="94" value="123"/>
</isomsg>

Many Thanks,
Suranga

The Channel will be calling the ISOMsg.pack() method you see, which in
turn will call it's Packager.pack() method to gather the raw bytes for
the Channel to send over the network.
