Packaging: Sample "E"
iPlanet^TM Application Server Samples

If you already deployed the packaging sample E, you can run the application by clicking here.

This samples illustrates

• Packaging of libraries in the form of JAR files in a WAR file.
• Use of property files packaged as part of a WAR

File Views for : pkgingEWAR.war, pkgingEEJB.jar ( 1 and 2 ), pkgingE.ear
Component View for all modules.

The sample illustrates the following concepts:

• Cross EJB invocation (within the context of one EJB JAR). The SimpleInterest and the CompoundInterest beans make calls to each other
• WAR to JAR communication (servlets making calls to EJBs)
• Packaging of libraries in a WAR file
• One JAR file (library.jar) contains samples.pkging.lib.DateLibrary which is needed by both SimpleInterestServlet and CompoundInterestServlet.
• The library is packaged under WEB-INF/lib/library.jar as required by spec
• Upon registration, the library is extracted to install_dir/ias/APPS/pkgingE/pkgingEWAR/WEB-INF/lib
• Resource files:
• interest.properties is a resource file that is accessed by servlets.
• The file is packaged as /props/interest.properties
• To access the property file from within a servlet, the following code is used:
• getServletContext().getResource("/props/interest.properties")
• Upon registration, the resource file is extracted to install_dir/ias/APPS/pkgingE/pkgingEWAR/WEB-INF/props/interest.properties

Assembling the Application

Deploying the Application

Running the Application
 

Assembling the Application

• Go to install_dir/ias/ias-samples/pkging/pkgingE/src. Execute the command 'build'. This command compiles the Java sources, creates the EJB stubs and skeletons and packages the WAR, EJB JAR and the final EAR file. The prebuilt EAR file at install_dir/ias/ias-samples/pkging/pkgingE/pkgingE.ear can also be used for deployment.
• The EAR file generated by the build command can be found at:

  install_dir/ias/ias-samples/pkging/pkgingE/assemble/ear/pkgingE.ear

Deploying the Application

Navigate to the directory containing the application's EAR file and run the iasdeploy command:

iasdeploy deployapp pkgingE.ear

This command deploys the application to the local machine.

Running the Application

Run the application by accessing the following link:

http://<hostname>:<port>/NASApp/pkgingE/index.html

Choose either "Simple Interest" or "Compound Interest". Enter the values on the input form and press "Submit". Notice how, on the final page, the application displays "suggested values" to be used. These values are retrieved from the property file interest.properties.
