Hi,

I am developing web applicaton using EJB2.0 Spec with JBOSS-4.0.3, PostgreSQL8.0 as DAtabase. Now in my database there is one table "partsmaster" in which there is one field "rfqpart" with type "bool" in POstgreSQL.
Now I want to insert values in that field using EJB from Client. I tried a field in my bean implementation Class with type "Boolean" & then
I tried to insert data into Table with client accessing that bean. When I tried to insert data I got Error as follows:-
============================
Cannot create Bean: java.rmi.UnmarshalException: Error unmarshaling return; nested exception is:
java.lang.ClassNotFoundException: org.postgresql.util.PSQLException (no security manager: RMI class loader disabled)
===============================

Also I tried with simply "boolean" instead of "Boolean" type iinto my EJB for corresponding column in database. But I am getting same Error.
& when I am omittimg the field "rfqpart" from my EJB implementation file then I am able to insert data into database.
So how to deal here with "rfqpart" field? Also What datatype (primary or generic) should I use here so that i can insert data into "rfqpart" field from my Client progarm using EJB2.0?

Please help me.

Thanx in advance.

Prash.
