- hello every body I work in project based on iso8583 using jpos 
for example I have data when I analyze it : 

[Fixed n 3 003] 022 [051] 

we can get 
fixed = format
 n = representation 
3 =maxlength 
003 =length 
022 = id 
051 = data element

 and from this data I can generate xml file 

<isofield class="org.jpos.iso.IFA_NUMERIC" id="12" length="006" name="TIME, LOCAL TRANSACTION" />

but the problem I want to know what are the specifications that help to choose the correct class ???

Hard to tell provided so limited information. 

The '051 = data element' is confusing here, looks like that's actually the 'data element's content'.

Yes is the data element content 
For me I receive log file content this data and my work is from the log file I should generate packager  (xml file ) but I don't know how I can get the correct type of class

That's a non ISO8583 standard field, seems to be a Length-Tag-Value. You probably need to handle it as a text field (IFA_LLLCHAR) and then parse it within your high level logic.

Hello team 

I am trying to validate ICC Data using the KW command. I am able to validate data using BP-Tools but however when I am using my application to send the command string to the HSM I am getting error code 15. I am using Thales 9000. Below is the sample data I am using

303030304B5733325534314137303030303030303332303431413730433238363445353542323331311481000000003301010E343200000000500000000000000002638000048800093221052400A770AD621800010E0FA501A00102000000000000000000000F010000000000000000000000000000803B8852C77282A5947B008000003200001930303030

I am using a java application to  interact with the HSM.

Hi,

As I see your other thread you are working with SPAN (now known as Mada). 

As far as the following is concernced

[Fixed n 3 003] 022 [051] 

Looks like it represents Field 22 POS Entry Mode of ISO8583. But in SPAN specifications Field 22 is of length 12.

Hope this helps.
