Usually ICC data uses TLV (tag length value) format. There is a TLVMsg in jpos that can be used or modified to your needs.
If its not TLV then it will be bitmapped and you will will need to define that as a isofieldpackager inside your packager. Search list for ISOFieldPackager usage inside your packager.

Your definitions dont give a clear picture and you will need to look at the spec or go to the people who have provided you the spec to understand the structure.

This is Iso message , Where i already have the packager only filed 43 packing wasnot correct ,  cant able to choose the class to pack the message so that it will get depacked correctly in the Network side .

I think I was off base here. Please ignore my previous response.
You have space delimited strings where the space will identify if a field is present or not.

What does not working mean?
Can you elaborate?

      <field id="127" value="EMVREF"/>
    </isomsg>

When this message recieved in Network simulator there was exception while depacking the filed 43.

 

error msg in network side : DE43_1030 : 043 : Auth - DE43(d) - DE 61, subfield 13 is not 840 and DE 43, positions 38-40 is not a valid three-character alphabetic country code
before upto filed 43 i correctly recieved in Network side , from filed 43 , parsing went wrong .


I guess my package was not correct for the field 43.

i need to choose the correct package so that it will correctly depacked in network.

Are you sending the data in the require format as defined by you earlier.

01

Name

02

Space

03

City

04

Space

05

Country Code

So space is the delimiter.
Your string "ICC POS Test           Paris         FRA"
name = ICC
City = Pos
Country=Test
Plus I think it needs a 3 digit country code and not FRA. ISO Country code for France is 250.
Plus Plus since its complaining about specific location 38-40 means the strings are probably fixed length strings?
 
I guess you need to make sure you remove spaces from the input string and format it based on Mastercards requirement.

How to form the packager for this. i am  bit confused here ?

I tried like this , now but its not working .

 <isofieldpackager
      id="43"
      length="40"
      name="CARD ACCEPTOR NAME/LOCATION"
      class="org.jpos.iso.IFB_LLHBINARY"
      packager="org.jpos.iso.packager.GenericSubFieldPackager"
      emitBitmap="false">
      <isofield
          id="1"
          length="22"
          name="Merchant Name"
          class="org.jpos.iso.IF_CHAR"/>
      <isofield
          id="2"
          length="1"
          name="space"
          class="org.jpos.iso.IF_CHAR"/>
      <isofield
          id="3"
          length="13"
          name="Merchant City"
          class="org.jpos.iso.IF_CHAR "/>
      <isofield
          id="4"
          length="1"
          name="space"
          class="org.jpos.iso.IF_CHAR"/>
      <isofield
          id="5"
          length="3"
          name="STATECODE"
          class="org.jpos.iso.IF_CHAR"/>
      </isofieldpackager>

is this correct ? 

[chhil]

My personal preference is to treat it as an opaque field and create the contents. I dont think you gain much by doing it this way other than doing a set("43.1",....)

Just create fixed field strings and put spaces where required.

My 2 francs :).
