hi all..I have totally three table Loanproposal,BankLoanProposal,Bankmaster in banking project.

Relationship:

LoanProposal 1--->* BankLoanProposal
LoanProposal 1--->1 Bankmaster

key:
Bankmaster(Bankid is pk) --->LoanProposal(Bankid is fk refering to Bankmaster)

Problem is:
I have many to one relationship between LoanProposal and Bankmaster.So When try to insert in Loanproposal table and
BankLoanProposal alone without inserting in Bankmaster table.It shows NullPointerException in place of Bankid in Loanproposal ..So can please tell me how to insert in Loanproposal table with already existing value of bankid..

you are using bi-directional or uni-directional
if bi-diretional u can load the Bankmaster object than update the both side link.

more over post ur mappings to make it more clear
