If you use a version of Netscape Navigator that has an embedded <APPLET> tag for the Windows Media Player 9 Series OCX control, the Java Runtime may not initialize the control. You receive the following error message:
java.lang.NoClassDefFoundError: sun/awt/DrawingSurface at WMPNS.WMP.getHWND(WMP.java) at WMPNS.WMP.start(WMP.java) at sun.applet.AppletPanel.run(Unknown Source) at java.lang.Thread.run(Unknown Source)java.lang.NoClassDefFoundError: sun/awt/DrawingSurface at WMPNS.WMP.getHWND(WMP.java) at WMPNS.WMP.start(WMP.java) at sun.applet.AppletPanel.run(Unknown Source) at java.lang.Thread.run(Unknown Source)
This problem occurs because the Windows Media Player 9 Series OCX control uses methods that are no longer supported by Netscape.

Microsoft has confirmed that this is a bug in the Microsoft products that are listed at the beginning of this article.
This fix is installed in the applet location of the latest version of the Java Runtime that is installed on the client computer. Under certain circumstances, events do not always fire in the client side script. The client is denied access in the Java console. At the time that this article was published, Microsoft did not have a fix for this issue. Web developers can work around this in two ways:
Use the ActiveX programming model with Netscape Navigator 7.1: Netscape Navigator 7.1 permits the Windows Media Player 9 Series OCX control to be embedded in Netscape by using code techniques that are similar to those for Microsoft Internet Explorer.
Host the .jar file from the Web site: If the .jar file does not exist in the Java Runtime directory, a Web developer can modify the Web site code to host the .jar file. If the Web site is the source of the .jar file, events should work. The modified <APPLET> code may look similar to the following code:
