public class simplesql

extends java.lang.Object

This example demonstrates obtaining a database connection using a DataSource object. See the simplesql.java file for code details.

You use the Administration Console as well as the command line to build, compile, and run this example.

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

4. Start WebLogic Server with the examples configuration.

Configure the Example

1. Open the Administration Console.

2. Verify that the Examples Web Application has been deployed on your server.

3. Verify that examples-dataSource-demoPool (a txdatasource) points to the demoPool connection pool and that the demoPool is enabled, as follows:

   • Click to expand the JDBC node in the left-hand pane.
   • Click to expand the Connection Pool node, then verify that demoPool appears under Connection Pool.
   • Click the demoPool connection pool, then click the Targets and Servers tabs in the right pane. Make sure that examplesServer is listed as a Chosen target server.
   • Click to expand the Tx Data Sources node, then verify that examples-dataSource-demoPool appears under Tx Data Sources.
   • Click the examples-dataSource-demoPool tx data source, then click the Configuration tab in the right pane. Make sure that the Pool Name attribute is set to demoPool.
   • Click the Targets and Servers tabs in the right pane. Make sure that examplesServer is listed as a Chosen target server.

Run the Example

1. Execute the following command in your development shell:

   prompt> ant run

Check the Output

When you run this example, the example makes a database connection using a tx data source and then performs some simple database opertaions. See the simplesql.java file for code details.

You should see the following results in the command window:

prompt>ant run
 Buildfile: build.xml
 
 run:
     [java] Making connection...
     [java]
     [java] Table empdemo doesn't need to be dropped.
     [java] Table empdemo created.
     [java] Number of rows inserted = 1
     [java] Number of rows deleted = 1
 
 BUILD SUCCESSFUL
