Error in Deploying CMP Bean!!!
somu rajan
1. what is the default data base for the weblogic 7.0.
2. should v create any table while deploying the CMP bean in a database. i think there is no need because the container will take care of it.
3. what is the need of <Data-source-name> in the deployment descriptor file weblogic-cmp-ejb-jar.xml. this is a mandatory field. can i give a random name here? if not, how 2 create a data source name.
please refer my deployment descriptor file.s

2. You need a datasource defined in the bean descriptor if you are using container managed persistence.
3. To create the datasource, start the server and use the admin console to create the connection pool and the datasource.
4. you can create tables in the database or turn on the auto create table feature in the rdbms file
