Validation of Supplier - Bank Details

Question

Gurus,
I want to validate the Supplier - Bank Details in the Supplier Bank Screen. The objective is to validate the sort code and account number against an external package. I will be calling a pl-sql call statement but I was wondering whether I should extend the EO or the VO.
The eo's are
oracle.apps.iby.schema.server.ExtBankAccountsEO
oracle.apps.iby.schema.server.ExtBankBranchesEO
Thanks
Regis.

Anand,
Many thanks & apolgies for not coming back earlier.
I've written my validation in the BexExtBankAccountsEOImpl.java which is below and compiles fine but I've few issues.
I'm currently working on 12.1.3 and using jdev 10.1.3.3
1) My extension didn't create a EOImpl.class file. It has only created a EO.xml , EOImpl.java & *EODefImpl.java. What would be reason.
2) On this version of Jdeveloper I can't find the substitution sub-menu. In the earlier versions of jdeveloper it used to pop-up on clicking the edit Business Component Project.
Kindly can you please help on the above.
Thanks
