Oracle® TopLink Examples EJB 2.0 CMP — Enterprise Information System (EIS) Example

In this example, objects are mapped to Indexed records (the Attunity demonstrations map objects to XML records). When developing a project that makes use of EIS access through JCA to TopLink, bear in mind that while both TopLink runtime and TopLink Workbench support mapping objects to XML records, only TopLink runtime supports mapping objects to Indexed records and Mapped records.

TopLink Workbench does not currently support mapping objects to Indexed records and Mapped records.

Configuration Requirements

Before you build and run the example, you must:

Follow the minimum configuration requirements for your environment in Configuring the Examples.
Copy the cciblackbox-tx.jar file to the <OC4J_INSTALL>/toplink/jlib directory.

Building and Running the Example

Use the following commands to build the example, reset the database, start the server and run the example:

To build the deployable EAR file, execute the build file. For Windows, select the build.cmd file. For UNIX, select the build.sh file. The build file invokes the build.xml ANT script, which retrieves supporting properties from the env.properties file and builds the example.
Ensure the database is running.
To reset database tables for this example, execute the resetDatabase file. For Windows, select the resetDatabase.cmd file. For UNIX, select the resetDatabase.sh file.
Start the OC4J server. When you start the server, set the system property toplink.log.level to "FINE" to turn on logging. For example, java -Dtoplink.log.level="FINE" -jar oc4j.jar.

To deploy the EAR file and Blackbox Adapter after server startup, execute the deploy file. For Windows, select the deploy.cmd file. For UNIX, select the deploy.sh file.

Note:

If you are using Internet Explorer and you change something in the file system, select View > Refresh before double clicking a *.cmd file in the Windows (filesystem) Explorer that IE provided. The *.cmd file will then execute correctly.

Double click the startClient.htm file or start a browser and point it to http://localhost:8888/cmp20_eis/mainPage.jsp.

Note:

If the CMP example was deployed previously, and the server is restarted after defining a non-Oracle data source (when there is no data source defined that references an Oracle driver), the Sun Blackbox JCA Adapter throws the following SQL exception: Exception Description: SQLException: No suitable driver. To avoid this, add the following to the beginning of the applyLogin method the AccountProject.java file:
public void applyLogin() {
     try {
           Class.forName
("oracle.jdbc.driver.OracleDriver");
     } catch(Exception e) {}
     ...
}

Example Files and Directories

Table: Files and Directories Used in this Example lists the supporting directories (and their contents) provided in this example.

Files and Directories Used in this Example

Directory	Contents
config	This directory contains configuration files used by both TopLink and OC4J. There are no TopLink-specific files. All files are J2EE or application server-specific files. All TopLink-specific mappings and metadata are created in Java source files in the src directory.
jsp	This directory contains the Java Server Page (JSP) files used in this example.
mw	This directory contains the TopLink Workbench project and supporting files for this example.
src	This directory contains all the supporting `.java` source files for the example. The `.java` files are stored in their respective package hierarchy.
