This example demonstrates the use of CDI 1.0 and JAX-RS in Red Hat JBoss Enterprise Application Platform.
The application this project produces is designed to be run on Red Hat JBoss Enterprise Application Platform 6.1 or later.
All you need to build this project is Java 6.0 (Java SDK 1.6) or later, Maven 3.0 or later.
If you have not yet done so, you must Configure Maven before testing the quickstarts.
The following shows the command line to start the server:
For Linux: JBOSS_HOME/bin/standalone.sh For Windows: JBOSS_HOME\bin\standalone.bat
NOTE: The following build command assumes you have configured your Maven user settings. If you have not, you must include Maven setting arguments on the command line. See Build and Deploy the Quickstarts for complete instructions and additional options.
Type this command to build and deploy the archive:
mvn clean install jboss-as:deploy
target/jboss-helloworld-rs.warto the running instance of the server.
The application is deployed to http://localhost:8080/jboss-helloworld-rs.
The XML content can be viewed by accessing the following URL: http://localhost:8080/jboss-helloworld-rs/rest/xml
The JSON content can be viewed by accessing this URL: http://localhost:8080/jboss-helloworld-rs/rest/json
When you are finished testing, type this command to undeploy the archive:
You can also start the server and deploy the quickstarts from Eclipse using JBoss tools. For more information, see Use JBoss Developer Studio or Eclipse to Run the Quickstarts
If you want to debug the source code or look at the Javadocs of any library in the project, run either of the following commands to pull them into your local repository. The IDE should then detect them.
mvn dependency:sources mvn dependency:resolve -Dclassifier=javadoc
If you do not yet have an OpenShift account and domain, Sign in to OpenShift to create the account and domain. Get Started with OpenShift will show you how to install the OpenShift Express command line interface.
Note that we use
USER_DOMAIN_NAME for these examples. You need to substitute it with your own OpenShift account user name.
Open a shell command prompt and change to a directory of your choice. Enter the following command to create a JBoss EAP 6 application:
rhc app create -a helloworldrs -t jbosseap-6
NOTE: The domain name for this application will be
helloworldrs-YOUR_DOMAIN_NAME.rhcloud.com. Be sure to replace
YOUR_DOMAIN_NAME with your own OpenShift account user name.
This command creates an OpenShift application named
helloworldrs and will run the application inside the
jbosseap-6 container. You should see some output similar to the following:
Application Options ------------------- Namespace: YOUR_DOMAIN_NAME Cartridges: jbosseap-6 (addtl. costs may apply) Gear Size: default Scaling: no Creating application 'helloworldrs' ... done Waiting for your DNS name to be available ... done Cloning into 'helloworldrs'... Warning: Permanently added the RSA host key for IP address '188.8.131.52' to the list of known hosts. Your application 'helloworldrs' is now available. URL: http://helloworldrs-YOUR_DOMAIN_NAME.rhcloud.com/ SSH to: 52864af85973ca430200006f@helloworldrs-YOUR_DOMAIN_NAME.rhcloud.com Git remote: ssh://52864af85973ca430200006f@helloworldrs-YOUR_DOMAIN_NAME.rhcloud.com/~/git/helloworldrs.git/ Cloned to: CURRENT_DIRECTORY/helloworldrs Run 'rhc show-app helloworldrs' for more details about your app.
The create command creates a git repository in the current directory with the same name as the application. Notice that the output also reports the URL at which the application can be accessed. Make sure it is available by typing the published url http://helloworldrs-YOUR_DOMAIN_NAME.rhcloud.com/ into a browser or use command line tools such as curl or wget. Be sure to replace
YOUR_DOMAIN_NAME with your OpenShift account domain name.
Now that you have confirmed it is working you can migrate the quickstart source. You do not need the generated default application, so navigate to the new git repository directory and tell git to remove the source and pom files:
cd helloworldrs git rm -r src pom.xml
Copy the source for the
helloworld-rs quickstart into this new git repository:
cp -r QUICKSTART_HOME/helloworld-rs/src . cp QUICKSTART_HOME/helloworld-rs/pom.xml .
You can now deploy the changes to your OpenShift application using git as follows:
git add src pom.xml git commit -m "helloworld-rs quickstart on OpenShift" git push
The final push command triggers the OpenShift infrastructure to build and deploy the changes.
Note that the
openshift profile in the
pom.xml file is activated by OpenShift. This causes the WAR built by OpenShift to be copied to the
deployments/ directory and deployed without a context path.
When the push command returns you can test the application by getting the following URLs either via a browser or using tools such as curl or wget. Be sure to replace the
YOUR_DOMAIN_NAME in the URL with your OpenShift account domain name.
You can use the OpenShift command line tools or the OpenShift web console to discover and control the application.
If you plan to test the
jax-rs-client quickstart on OpenShift, you may want to wait to delete this application because it is also used by that quickstart for testing. When you are finished with the application you can delete if from OpenShift as follows:
rhc app-delete -a helloworldrs
Note: There is a limit to the number of applications you can deploy concurrently to OpenShift. If the
rhc app create command returns an error indicating you have reached that limit, you must delete an existing application before you continue.
rhc domain show
rhc app-delete -a APPLICATION_NAME_TO_DELETE
