Prepare Application Clients run-time library component for Java Web Start

The Java Web Start client is used with platforms that support a Web browser. For a Thin Application client application to be launched using Java Web Start (JWS), you also need to create a Java Network Launching Protocol (JNLP) component to serve the Application Clients run-time library JAR files from the Application server. This JNLP component is referenced in the client application JNLP file with the <extension> tag. This article provides the steps to build the Application Clients run-time library component from an Application Clients installation. It is packaged as its own Web Archive Resource (WAR) file or to the same WAR file that contains the Application Clients run-time dependency component, and can be installed in an Application server.

Java Web Start is not supported on i5/OS. Install the Application Client for WebSphere Application Server for the platform to which client applications deploy.

Procedure

1. Install the Application Clients on the client application supported operating system.

2. Change the directory to the installation bin directory.

3. Run buildClientLibJars to copy the Application Clients run-time library JAR files from the Application Clients installation to a temporary directory. All the JAR files in the temporary directory are signed.

   1. This step also requires you to create a keystroke file, such as myKeystore.

   2. You must also create a self-signed certificate for the myKeystore file.

4. Create an Application Clients run-time installer JNLP descriptor file in the same temporary directory as the previous step. See the sample JNLP file shown in the Example section of this topic.

5. Package these JAR files and the Application Clients run-time library component JNLP descriptor file into a WAR file. You can also package both Application Clients run-time library component and Application Clients run-time dependency component in the same WAR file. This WAR file is packaged into an EAR file that can deployed to an Application server.
