How to get bitmap field values

Hi,
Any idea how to get the primary and secondary bitmap values using jpos.
I am trying to search for these values by using ISOMsg.hasField(1) and
ISOMsg.hasField(1).
However, the bitmap fields are not found. Please help.

Thanks & regards,
Suvodip

Re: How to get bitmap field values

Most people trying to access the bitmap want to do so in order to figure
out if a field is present or not. You can do that in jPOS using ISOMsg's
hasField method (i.e. m.hasField(35)). 

We internally store a bitset in an internal field -1, you can use
code like this:

 import java.util.BitSet;

 BitSet bset = (BitSet) m.getValue(-1);

But I wonder if you really need to. What's your use case?

RE: How to get bitmap field values

Alexandro,
I need to check if the ISOMessage contains my pre-defined ISO fields and
if there are any extra fields present.
So, what I plan to do is pick up the 16/32 character bitmap field and
then compare it with my template bitmap to check that the fields needed
are present. Checking for each field I need with hasField() is a lengthy
process.

Is there a way to get the primary and secondary bitmap fields as
strings, please? like the other fields using m.getValue().

Regards,
Suvodip

I understand. You can't do that out-of-the-box, but you can get a hold
of the BitSet (using m.getValue(-1)) and then using ISOUtil.bitSet2byte
in order to get a byte[]. 

Then you can either compare at the byte[] array level or use
ISOUtil.hexString and deal with Strings.

In some of my systems I use a 'CheckField' transaction participant that
you can configure like this:

  <participant class="org.jpos.jcard.CheckFields" logger="Q2" realm="CheckRequiredFields">
   <property name="mandatory" value="PCODE,7,11,12,13,AMOUNT,PAN,41" />
   <property name="optional"  value="17,32,37,42,43,46,60,63,111" />
  </participant>

you can use the code as a reference: http://jpos.org/private/CheckFields.java

Thanks Alejandro. I guess I can work with these.
Will work on this tomorrow, it's evening in UK now :)

RE: How to get bitmap field values

To explain it more easily, if the ISO string is
"962404000000008000000000000000003200000001", I want a method which
would return me "0400000000800000" which is the bitmap value for this
message.
