Please Help Me for this Problem.

[ronald_van_kuij]

Arif,

It is WEEKEND!!! Many of us to other things then, so PLEASE have a little patience.

Secondly, have you had a look what happens here:

Caused by: java.lang.NullPointerException
at org.activiti.spring.test.jpa.LoanRequestBean.newLoanRequest(LoanRequestBean.java:39)

We CANNOT GUESS… it is YOUR code…

So you first have to learn how to provide us with the right information, and make sure it is an activiti problem…
