OpenEdge Development:<br />Java Open Clients Building Java applets as Open Clients

You can build a Java applet that runs as an Open Client; that is, the applet can make proxy method calls to remote AppServer procedures from the Web browser environment. However, you must include additional code to allow the Web browser to accept the Open Client applet for execution. The Open Client supports Java applets by using an HTML page to distribute the appropriate files. There are a couple of factors you must consider:

The Open Client applet obtains the HTTP Basic authentication and Proxy Web server information from the end user and then passes the information to the Open Client. You cannot, however, rely on the browser to provide the user interaction; your applet must perform this task. You also might have to access the Proxy Web server configuration information from the browser. In this case, the applet also needs to obtain the Proxy Web server information from the end user.

Open Client applets can run on both a company intranet and the Internet. As a result, you need to sign your Java code with a digital certificate, and your applet must get permission to perform a network connection.
