Bhushan,
This is what I suggest:
1. Use a standard EDI translator to generate the flat file.
2. Very importantly, design your flat-file in a manner that will help your
class generator you generate appropriate classes.
3. All you need to do now is to map the standard EDI doc to your flat file.
4. The reverse process of generating the flat-file from your class, mapping
it to the standard EDI doc also becomes straight forward.
Hope this helps.
Thanks,
Ajay

Hi,
What I want is to have a Translator which will parse the EDI
documents and give me the data in the form of Java objects for each
transaction set. (Instead of a flat file).
I am giving my design approach below. Please let me know if this is
a practical design approach or it is too simplistic (non practical) . Also
let us know what are the other issues which we would have to handle in our
translator e.g security etc.
Also you could suggest to me how I would be able to achieve my
objective using the currently available translator's. Please note that I do
not want to code for each Java class. I would prefer the Java classes to be
generated and readily available. Typically most translators provide EDI to
flat file conversion. And we have to write Java classes which would parse
these files and populate the data mambers. Is there no translator where we
can tell it to give me the data in Java objects format?
My design approach is as follows :
It will consist of 2 components :
1] Class Generator (will be used at design time to generate Java classes
i.e. for PO, Invoice, PoAckw etc.)
2] Translator.
I am explaining the general process in detail as follows :
Java class Development Process:
The client who has bought this product would use the class generator to
parse the X12 standard files and will generate a Java class mapping to each
standard (mapper) .i.e a class would be generated for PO, another class
would be generated for Invoice etc.
Runtime Translator functionality :
The translator will do the job of parsing the EDI file and reading
the various functional groups and the transaction sets within the functional
groups. The translator class will instantiate Java objects corresponding to
those transaction sets and after parsing the EDI document it will populate
the respective objects for each transaction set. Before populating the
objects it would be doing the validation of the EDI file looking at the
Standard file for that transaction set. Thus we would be doing the EDI data
to Java object conversion.
Translator would be having the functionality of generating the
response EDI files also. Our client would be given the Java classes
generated by our Java class generator. He would be using the members in
these classes to populate the data and he would send these objects to the
Translator. The translator would look read these objects and generate an EDI
file.
Thanks,
Bhushan.
