Hi

I am developing an entity beans in Visual Age for Java - it is a fairly straight forward for the minute - i just want to be able to connect to the DB and create a row in the table.

i ahve written my bean and have connected to the DB2 database via the schema browser - however when i try to use the Map Browser to link the variables in the bean with the column in the database -- i am getting a bit lost!

I have done this before but not for just a bean developed on its own... is there a step i have missed - all and any help much appreciated.

Just so I understand where you are, you've created your own entity bean without using any of the VAJ wizards and you've retrieved the schema from DB2, right?  And you want to know how to use the Map Browser to do your mappings?

I'm assuming all your instance variables are added to the bean already.  If not, make sure to add them. (assuming this is a CMP bean, right-click on the bean in the "Enterprise Beans" list on the Workbench and Add-->CMP Field...make sure to check the "key" box if your field is part of a primary key).

Open your Map browser and select your Datastore Map from the list.  The Persistent Classes list should fill up with the names of your entity beans.  Select the bean you want to map and go to "Table Maps-->New Table Map-->Add Table Map with No Inheritance".

A dialog will pop up with a combo box filled with the tables in your schema...select the table you want to map your bean to and click OK.

Now you'll see the table schema listed in the "Table Maps" list...right-click on it and select "Edit Property Maps".  From here, proceed to map all of your bean instance variables to table columns.

Lemme know if that does it for ya.
