Description
| Interface Summary | |
| Account | The methods in this interface are the public face of AccountBean. |
| AccountHome | This interface is the home interface for the EJBean AccountBean. |
| Class Summary | |
| AccountBean | AccountBean is an EntityBean. |
| Client | This class demonstrates calling an entity EJBean, followed by two exercises: |
| Exception Summary | |
| ProcessingErrorException | This class is used with the WebLogic EJBean container-managed example package. |
This example is a package that demonstrates an Enterprise JavaBean. The example is an entity EJBean called AccountBean.
The example demonstrates:
To get the most out of this example, first read through the source code files.
This EJB 1.1 example is not shipped pre-built. Before you can run this example, you must first build it following the instructions in Build the example.
These four sections cover what to do:
This example is preconfigured to work with the PointBase database, included with the WebLogic Server distribution. You'll need to set up the persistent storage of the EJBean. You'll use a database for the persistent storage of the entity EJBean. The persistent storage is completely invisible to the client; the actual storage is handled automatically by the container and not by the EJBean. All database properties, such as the login name and password, are defined in the connection pool. A preconfigured connection pool is included in the example server.
With database persistence, each instance of an EJBean is written to a row in a table. If you want or need to run this example with Oracle, see Database SetUp for instructions.
We provide a build script for you to build the example:
The build script is build.xml.
Run the build script using the following Java ant command:
prompt> ant
The script will build the example and place the files in the correct locations in your WebLogic Server distribution:
Running the build script places the EJB in the %applications% directory, where it automatically deploys once the server is started. If you are already running the server and then build the EJB, it is automatically placed in this directory and instantly deployed.
Additional information on using the build scripts is found in Building Enterprise JavaBean examples
A list of deployed EJBs displays.
If you need more information about how to use connection pools, read Programming WebLogic JDBC.
