Applet clients are capable of communicating over the HTTP protocol
and the RMI-IIOP protocol.
Before you begin
Applet clients have the following setup requirements:
- These clients are available on the Windows platforms. Check the prerequisites
page for information on platform support and product prerequisites.
- The browser installation precedes the client code installation.
About this task
Unlike typical applets that reside on either Web servers or WebSphere
Application Servers 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
- Install the Application Client for WebSphere Application Server.
- Select the applet client feature.
- From the IBM Control Panel for Java, enter the following code:
-Djava.security.policy=<app_client_root>\properties\client.policy
-Dwas.install.root=<app_client_root>
-Djava.ext.dirs=<app_client_root>\java\jre\lib\ext;
<app_client_root>\lib;
<app_client_root>\plugins;
<app_client_root>\lib\ext;
<app_client_root>\lib\WMQ\java\lib"
-Dcom.ibm.CORBA.ConfigURL=file:<app_client_root>\properties\sas.client.props
-Dcom.ibm.SSL.ConfigURL=file:<app_client_root>\properties\ssl.client.props
-classpath <app_client_root>\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 Server
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, you can enter most options available
from the command prompt (for example, -cp, classpath, and others) in this
field as well.
- Access the IBM Control Panel for Java from the Start menu. Click Start > Control
panel > select the IBM Control Panel for Java.
- The applet container is the Web browser and the Java plug-in combination.
You must first install the Applet client feature from the Application Client
for WebSphere Application Server so that the browser recognizes the IBM product
Java plug-in.
