Develop applet client code

 

Before you begin

Applet clients have the following setup requirements:

• These clients are available on the Windows XP or Windows 2000 platforms. Check the prerequisites page for information on platform support and product prerequisites.

• The browser installation precedes the client code installation.

 

Overview

Unlike typical applets that reside on either Web servers or WAS appservers and can only communicate using the HTTP protocol, applet clients are capable of communicating over the HTTP protocol and the RMI-IIOP protocol. This additional capability gives the applet direct access to enterprise beans.

 

Procedure

1. Run the application server client installation.

2. Select the applet client option.

3. Install an applet client.

4. Install the WAS plug-in for the browser. From the WAS Java Plug-in control panel, enter the following code

   -Djava.security.policy=<product_installation_dir>\properties\client.policy
   -Dwas.install.root=<product_installation_dir>
   -Djava.ext.dirs=<product_installation_dir>\classes;
   <product_installation_dir>\java\jre\lib\ext;
   <product_installation_dir>\java\jre\lib;
   <product_installation_dir>\lib;<product_installation_dir>\properties
   -Dcom.ibm.CORBA.ConfigURL=file:<product_installation_dir>\properties\sas.client.props
   -classpath <product_installation_dir>\properties
   

   Note: The previous entries are automatically placed into the WebSphere Application Server control panel for the Java plug-in user who installed the WebSphere Application Sever Application Client. If this sample is being run by a user other than the person who installed the client, the user must enter the entries.

   • The Java Run-Time Parameters field is similar to the command prompt when using command line options. Therefore, one can enter most options available from the command prompt (for example, -cp, classpath, and others) in this field as well.

   • Access the control panel from the Start menu. Click Start > Control panel > select the product Java plug-in.

   • The applet container is the Web browser and the Java plug-in combination. You must first install the WAS Applet client so that the browser recognizes the IBM product Java plug-in.
