Deploying Java Web Applications

Adding a Web Application

You can deploy a web application to any existing virtual server.

To deploy a web application

Before You Begin

• Identify a virtual server where you will need to deploy the web application.

• Be sure you have either the web application archive (.war file) or know the web application path in the server.

Web applications can be deployed through wadm, Administration Console and other supported IDEs.

1. To deploy a web application, click Server Configuration and then click the Virtual Servers tab.

2. Select the virtual server in which you will need to deploy the web application.

3. Click the Web Applications tab > New button.

4. Specify the web application package.

   If you need to upload a web application archive, click the Browse button and select the archive. Optionally, you can also specify a web application archive located in the server.

5. Specify the URI for your web application. The URL will be the applications context root and is relative to the server host.

6. Provide a short description about the web application.

7. Enable/Disable JSP Pre-compilation.

   Enabling this directive will allow all the JSPs present in the web application to be pre-compiled to improve performance.

8. Enable the application.

   When a web application state is set to be Disabled, it will not be available on request. However you can toggle this option anytime without redeploying the application to the instances.

9. Deploy the application.

   Click Deploy to deploy the web application.

   You can access the application with the context root specified. E.g. http://<your-server>:<port>/<URI>

   Note –

   Using CLI

   wadm> add-webapp --user=admin --password-file=admin.passwd --host=localhost --port=8888 --config=config1 --vs=HOSTNAME --uri=/hello /home/test/hello.war

   See CLI Reference, add-webapp(1).

   For large web applications, using a target directory outside Web Server's installation directory improves Admin Server's performance. The CLI add-webapp(1) --directory option is used for this purpose.

Deploying a Web Application Directory

A directory on the administration server host machine can be deployed to a configuration using the –file-on-server option. Execute the following command:

wadm> add-webapp --user=admin-user --password-file=admin.passwd 
--port=8989 --vs=vs1 --config=config1 --file-on-server
--uri=/mywebapp /space/tmp/mywebapp

Pre-compiling JSPs During Deployment

To pre-compile JSPs in a web application while deploying the web application, execute the command with –precompilejsp option as given below:

wadm> add-webapp --user=admin-user --password-file=admin.passwd 
--port=8989 --vs=vs1 --config=config1 --file-on-server --uri=/mywebapp
--precompilejsp mywebapp.war
