Cloud: Java Cloud Service SDK

#

## Sample Introduction

This sample demonstrates how to developing a simple JavaServer Faces application using Facelets technology. It usually requires the following activities:

- Developing the backing beans and adding managed bean declarations
- Creating the Facelets views using the component tags
- Defining page navigation
- Mapping the FacesServlet instance

The application presents you with a page that asks you to guess a number between 0 and 10, validates your input against a random number, and responds with another page that informs you whether you guessed the number correctly or incorrectly.

For details about the sample code, see the files that are listed in the following table.

## Main Files Used in the sample

Directory Location:

SDK_HOME/samples/ee6/guessnumber

(where SDK_HOME is the directory containing your Java Cloud Service installation)

File Click source files to view code. | Description
--- | ---
build.xml | Ant build file that contains targets for building, deploying, and running the sample.
greeting.xhtml | A Facelets view that contains JavaServer Faces components and connects to the backing bean through the Expression Language as the welcome page.
response.xhtml | A Facelets XHTML web page that displays the expression provided by the backing bean as a response page to user request.
web.xml | Web application deployment descriptor that maps the FacesServlet.
weblogic.xml | Oracle WebLogic Server-specific web application deployment descriptor that declares the application context root and the WebLogic shared library reference.
glassfish-web.xml | GlassFish Server-specific Web application deployment descriptor
UserNumberBean.java | JavaServer Faces backing bean class that defines the properties and business methods, which are associated with the Facelets components and registers the backing bean as a resource with JavaServer Faces implementation via the annotation `@ManagedBean`.

## Prepare the Sample

### Prerequisites for Deploying the Sample Locally

1. Install Oracle WebLogic Server and configure it. This is required only if you want to deploy applications locally
2. In the `SDK_HOME/samples/myenv.*` script, set the MW_HOME environment variable to the directory where WebLogic Server is installed.
3. Run the script:
   - On Linux, run: `. ./myenv.sh`
   - On Windows, run: `myenv.cmd`
4. Set the following environment variables in the `SDK_HOME/samples/build.common.properties` properties file:
   - set local to true, the default value is false.
   - set identity-domain to the identity domain name where you will deploy the application.
   - set service-instance to the service instance name where you will deploy the application.
   - set local-admin-url to the URL of the local WebLogic admin server.
   - set local-admin-user to the admin user who has permission to deploy the application.

You can also refer to Preparing Applications for Java Cloud Service Deployment in Using Oracle Java Cloud Service and the sample main page for more details.

### Prerequisites for Deploying the Sample on Java Cloud Service

If you are going to install your application only on a remote Java Cloud Service instance, you will not need to have WebLogic Server installed locally. Just make sure that "ant" and "javac" are available in the path.

Set the following environment variables in the `SDK_HOME/samples/build.common.properties` properties file:

- set identity-domain to the identity domain name where you will deploy the application.
- set service-instance to the service instance name where you will deploy the application.
- set cloud-admin-url to the admin URL that is used to deploy the application on Oracle Cloud.
- set cloud-admin-user to the admin user who has permission to deploy the application on Oracle Cloud.

## Build and Deploy the Sample

To build the sample, follow these steps:

1. Change to the `SDK_HOME/samples/ee6/guessnumber` directory, where SDK_HOME refers to the main Oracle Java Cloud SDK installation directory, such as `/home/user/oracle-javacloud-sdk`.
2. Execute the following command in the shell. (If you deploy the sample to local environment, choose the shell where you run the `myenv.*` script.)
   `ant clean`
   This command cleans the build directory.
   `ant build`
   This command compiles and stages the sample.
3. Execute the following command in the shell. (If you deploy the sample to local environment, choose the shell where you run the `myenv.*` script.)
   `ant install`
   This command installs the sample on the local WebLogic Server or a remote Java Cloud Service instance.

The Ant command uses the `build.xml` file in the `SDK_HOME/samples/ee6/guessnumber` directory, to build the sample.

## Run the Sample

1. Complete the steps in the "Prepare the Sample" section.
2. Execute the following command in the shell (If you deploy the sample to local environment, choose the shell where you run the `myenv.*` script.)
   `ant run`
   This command tries to automatically launch the web browser with the URL pattern `http://server:port/guessnumber`, where the server would include the identity domain and service instance name. For example, `https://java1-wnctrial.java.dc1.c9labga.us.oracle.com/guessnumber`, where `java1` is the service instance name and `wnctrial` is the identity domain. The rest of the host name `java.dc1.c9labga.us.oracle.com` is based on the environment. The actual URL should be printed when you run the sample.
   If the above does not work, you can open a browser, then copy and paste the above URL.
   For non-Windows and non-Mac machines, make sure that you have specified valid browser for the `default.browser` property in `SDK_HOME/samples/build.common.properties.`
