Sun GlassFish Enterprise Server 

Samples Main Page

The Servlet 3.0 Asynchronous Sample Application

This is a simple Servlet 3.0 application using asychronous API.

Servlet

The servlet is responsible for asynchronous request processing.

Deployment Descriptor

The good news is the deployment descriptor is no longer required!

Sun GlassFish Enterprise Server Specific Deployment Configuration

There is no need to define any Sun GlassFish Enterprise Server specific deployment descrpitor (sun-web.xml) for this example.

Building, Deploying, and Running the Application

Perform the following steps to build, deploy, and run the application:

  1. Set up your build environment and configure the application server with which the build system has to work by following the common build instructions.
  2. app_dir is the sample application base directory: samples_install_dir/javaee6/web/servlet/async-request-war
  3. Change directory to app_dir.
  4. Build, deploy, and run the sample application using the all target.
  5. app_dir> ant all

    You can replace the ant all command with the following set of commands:

    app_dir> ant default compiles and packages the application

    app_dir> ant deploy deploys it to application server

  6. To run this chat application, you need two browsers, say Browser A and Browser B. 
  7. Use the target undeploy to undeploy the application.

    app_dir> ant undeploy

  8. Use the target clean to remove the temporary directories like build and dist.

    app_dir> ant clean

Building, Deploying, and Running the Application in NetBeans IDE

Perform the following steps to build, deploy, and run the application using NetBeans IDE:

  1. Refer to the common build instructions for setting up NetBeans IDE and Sun GlassFish Enterprise Server.
  2. In the NetBeans IDE, choose File → Open Project (Ctrl-Shift-O), navigate to the samples_install_dir/javaee6/web/servlet/ directory, select async-request-war, and click Open Project.
  3. In the Projects tab, right click async-request-war and select Run to build, deploy, and run the project.

Troubleshooting

If you have problems when running the application, refer the troubleshooting document.
