Specifying unique key constraint in jbosscmp-jdbc.xml

Hi All,

I am using an entity bean to create my table in MySQL4.1.13
I have a table called user which has userid,username,password as its columns.
The userid is a primary key over here.
But I want the user name to be unique.
I.e if a user with the name 'Adrian' is present in the database then another user with this user name should not be created.

I have been told that you can configure a unique key in jbosscmp-jdbc.xml using insert-after-ejb-post-create.

But i dont know how to use it.
Can anyone give me a sample code for using this.

Any help would be appreciated.
Thanks

Hi Adrian,

Just in case the answer you're seeking is not forthcoming, do consider setting the username as a unique column in your table at the database.

Sorry that I couldn't provide the actual answer that you want.
