Hi all,
I am in the process of learning
EJB from the scratch. I am also preparing for SCBCD in the process. I wrote a CMP bean to insert a row of data into the database. I am using the j2ee RI to deploy my bean.
I have written the RemoteComponent interface, Home interface and the bean. I have successfully deployed it too using the deploytool in j2ee. The database i use is the default Cloudscape.
I get the following error when i try to call create on the Home object ..
home.create(.....);
this gives out a transactionRollBackException.
Can any one kindly help me on how to get over this issue ?
