simpleselect | This example shows how to use a WebLogic pool driver to make a JDBC connection for a servlet. |
This example shows how to use a WebLogic pool driver to make a JDBC connection for use in an HTTP servlet. This server-side JDBC pool can use a few JDBC connections that are created when the WebLogic Server starts up to serve many clients displaying database data in an HTTP servlet. (The WebLogic Tour uses a single-user version of a Cloudscape database with a server-side connection pool.)
The method uses the pool driver for database access and jsp to generate an HTML page for display.
You'll need a database with the "emp" table in it, like the DEMO database that comes with an Oracle installation. If you want to create the table yourself, you can create the DEMO database using the ddl at /samples/examples/utils/ddl/demo.ddl and the schema utility. For information on the schema utility see Using WebLogic Utilites.
You can use the Administration Console as well as the command line to build, compile, and run this example.
$ java weblogic.jspc -d %EX_WEBAPP_CLASSES% simpleselect.jsp
$ copy simpleselect.jsp %APPLICATIONS%\examplesWebApp
http://WebLogicHost:port/examplesWebApp/simpleselect.jsp
Where WebLogicHost:port is the hostname and port number of your WebLogic Server.
