This answer works, and it deserves to be called the &quot;hack of all ages&quot;. &nbsp;I'm not sure how the language specification should be changed, but as long as applets must make use of libraries that exist in some browsers, but not in others, some form of conditional compilation is required. &nbsp;Notice that with this technique *all* the work must be done in a constructor, because if you wanted to call a method on this class, it would have to be loaded and verified on both platforms and would toss exceptions on the one that does not contain some of the classes that it uses.<br />

Thanks,<br />

Netscape defines a set of classes to grant applets permissions to do specific things. &nbsp;I use the PrivilegeManager.enablePri<wbr />vilege method to request permissions for my signed applet. &nbsp;Including these calls in my code causes IE4 to toss exceptions because it can't find the Netscape classes. &nbsp;Java doesn't give me conditional complitation, and I don't want to maintain 2 sets of sources, one for each browser.<br />

I can detect which browser my applet is running under.<br />

Is there any way to use the Netscape classes from code that can be run without exceptions under IE4?

Printing in IE4 and Netscape4

Java is a platform-independent, object-oriented programming language and run-time environment, designed to have as few implementation dependencies as possible such that developers can write one set of code across all platforms using libraries. Most devices will not run Java natively, and require a run-time component to be installed in order to execute a Java program.
