The parent bean sample and the child bean together sample show subclassing an EJB. Each samples shows a stateless session bean. The parent bean contains methods that are overwritten by the subclassed child bean and the methods that are specific to the parent bean.
The following directory contains the Java source files and XML based deployment descriptors.
Windows NT:
$TUXDIR\samples\j2ee\ejb\subclass\parent
UNIX:
$TUXDIR/samples/j2ee/ejb/subclass/parent
A common build script is provided for all the EJB samples and it can be found in the following directory:
$TUXDIR\samples\j2ee\ejb
Unix:
$TUXDIR/samples/j2ee/ejb
The following table lists and describes all the files for this sample application:
ejb-jar.xml
The XML deployment descriptor file used to add the bean to the EJB container
weblogic-ejb-extensions.xml
The file containing the WLE extensions to the deployment descriptor DTD
Client.Java
The Java source code for the client
ParentBean.java
The Java source code for the stateless session bean. This class contains the business logic method implementations and methods required by EJB 1.1 specification.
Parent.java
The Java source code for the Remote interface of the ParentBean class
ParentBean
ParentHome.java
The Java source code for the Home interface of the the ParentBean class
The following table lists and describes the utility files for this sample application. These files are generated based on the WLE installation environment. Since a common build script is provided for all the EJB samples, instructions to build and execute the samples are provided later in Building and Running the EJB Sample Applications. The following files generated in the same directory as where the source files are found.
runme.cmd
The Windows NT batch file that contains commands to set the environment, boot the server, and execute the client for this sample
runme.ksh
The UNIX Korn shell script that contains commands to boot the server and execute the client for this sample
run_client.cmd
The batch file to run the client on Windows NT systems
run_client.ksh
The script file to run the client on UNIX systems
setenv.cmd
The batch file to set the necessary environment variables on Windows NT systems
setenv.ksh
The script file to set the necessary environment variables on UNIX systems
ubbconfig
The WLE server configuration file to be used on UNIX systems
ubbconfig.nt
The WLE server configuration file to be used on Windows NT systems
ejb_subclass_parent.jar
The ejb-jar file that contains the source file classes, the container-specific class files generated by the ejbc command, and the deployment descriptor files. This is the ejb-jar file that is deployed on the WLE server.
