Lesson 5: Deploying the application components

To deploy the components in the application, run the application process on the new environment.
Now that you have an environment and all the necessary processes, you can deploy the components by running the application process.
  1. Open the application page by clicking Applications and then clicking the application name.
  2. In the same row as your environment, click the Request Process icon.
  3. In the Run Process window, in the Process list, select the Deploy JPetStore process
  4. Under Component Versions, select Latest Version for each component. You must select a version for each component; if you do not select a version, that component is not deployed.
  5. When you have selected a version for each component, click Submit.
The web page shows you the progress of the application process request. From this page, you can watch as the processes run. The following figure shows the beginning of the application process, when the component process for the application component is running.

If the process runs successfully, the request shows that each component process is finished, as in the following figure:

In this case, you can view the running application at the following URL, by substituting the host name of your target system for hostname:
http://hostname:8080/JPetStore
The application shows a simple online shopping site in the form of a pet store. The following figure shows the home page:

From the home page, click Enter the Store and then browse the items that are available, as shown in the following figure:

If the application process did not run successfully, one of the component processes might have failed. In this case, the process is listed with a status of Failed. To troubleshoot this failed process, expand the log section for the component and click Details:
The log for the application process request, showing a component process that did not complete
When you click Details, the page shows the log for the component process. From here, you can look at the command-line output log for each step in the process by clicking the Output Log icon.
The log for the component process that did not complete
If one of your component processes did not complete, identify the step that did not complete. Verify that the properties for that step are correct and that the steps are in the correct order in the process. Then, run the application process again.
Note: If you run the application process again, be sure to clear the Only Changed Versions check box. If you leave this check box selected, the server runs the component processes only for components that have new versions.
Clearing the Only Changed Versions check box so all of the components are deployed

Lesson checkpoint

This application process installed each of the components in the application by running their component processes.
Application processes can also uninstall or update components or run other configuration tasks for the application and its components.
