Hi all
We are using the CMP for our beans & we need to create a unique ID
(primary key ) for each row in a table. We have written a trigger in the
database ( Oracle 8i ) which creates this unique ID before inserting a new
record in the database.
I am not assigning a value to the primary key in the ejbCreate method.
When I try to call a create method on my entity bean through client code I
am getting following error
Sat Jul 01 18:19:39 GMT+05:30 2000:<I> <ServletContext-General>
ProductClient: init
Error occured java.rmi.UnexpectedException: Unexpected exception in
examples.market.ProductBean.create():
java.lang.NullPointerException at
examples.market.ProductPK.hashCode(ProductPK.java:30)
at com.sun.java.util.collections.HashMap.get(HashMap.java, Compiled
Code)
at
com.sun.java.util.collections.Collections$SynchronizedMap.get(Collections.ja
va, Compiled Code)
We are using Weblogic 5.1 app server & Oracle 8i
ProductBean is the name of our bean
ProductPK is the primary key
Has anybody has done this before ? Can anybody pls help me finding the
solution ? What are other possible ways ?
Thanks in advance.
