Before you deploy a data access application into the WebSphere Application Server - Express environment, you must first ensure that the appropriate database objects are available. This action includes creating and configuring any databases or tables required, setting necessary configuration parameters to handle expected load, and configuring any necessary JDBC providers and data source objects for JSPs and servlets to use.
If your database configuration does not already exist, create a database and the tables that are required by your application. Use your database server interfaces to create the tables.
In addition, consider Security of lookups.
See the WebSphere Development Studio Client Help for more information about deploying your data access application.
