[eclipselink-users] WebSphere datasource note working for insert update

["Atish Potdar" <a.potdar@xxxxxxxxxxxx>]

Hi Group,

 

I have configured datasource in WebSphere to connect to DB2 and using it in my J2EE application. The same datasource has been configured in Persistence,xml. When I run the application then it can read and display the data but when I tried to create or update records then it throws following error. Can any body please advice on this?

 

Thanks in advance.
