Greetings HonorGod,
I have a web application that has been deployed to production . It uses some entity beans. One of the entity beans in production environment is not being persisted properly because it is mapped to a development database and also using an incorrect table name that was mispelled by the developers.
My understanding is that it is using some default mapping which was done at development time in the application.
I would like to correct this information (hopefully through the WAS Admin console) so that the entity bean uses the correct schema and table name .
Is there a place in the admin console where I can change the persistence information and also correct the misspelled table name so that it uses the correct schema and the correct table that is in production.
I know when we migrate a regular web application(without any entity beans) to production we just change the datasources so that they refer to production schemas and everything works because the code uses a resource reference in the jndi look up.
Hope this helps

Yikes. I'm sorry, I completely forgot about this question. Please forgive me.
If the configuration information about the database is hard coded in the application, then the application needs to be changed.
On the other hand, if the information about the database is in the datasource, then you can:
- login to your admin console
- click on & expand the Resources section (left frame)
- click on & expand the JDBC section
- click on the Datasource link
- click on the Datasource name to be modified
- make the changes
- test the connection
- and save your changes.
Good luck
