This servlet demonstrates using a DataSource to get a connection to a database and execute a simple sql query using the connection. The example uses the Pointbase database management system, provided in an evaluation version with WebLogic Server.

Build the Example

1. Open a new command shell.

2. Set up this development shell as described in Setting up Your Environment for Building and Running the Examples.
3. Compile the example by executing an ant build script or a command.
   • An ant build script is available in the samples\examples\jdbc\datasource directory. Enter the following command to execute the build script:

      ant

   • Enter the following command to compile the example:

     javac -d %EX_WEBAPP_CLASSES% simplesqlServlet.java

Start WebLogic Server with the examples configuration.

Configure the Server

1. Make sure that the examplesWebApp is deployed on your server.

2. Use the Administration Console to confirm that the examples-dataSource-demoPool DataSource is deployed on the examplesServer. For more information see JDBC Data Sources.

Run the Example

1. Use a web browser to load the following URL:

   http://localhost:7001/examplesWebApp/simplesqlServlet
