The ARCHIVE attribute is supported in both the EMBED and OBJECT tags. The most common mistake is to put the JAR files in the wrong order. For example, if you use the Swing set in Java Plug-in Software and specify ARCHIVE=”Myjar.jar,swing.jar,…” Java Plug-in Software will fail to load the applet because by the time Myjar.jar is loaded and Java Plug-in Software tries to initialize the applet, swing.jar is not yet loaded. The JAR files in the ARCHIVE should be in the order of dependency. Since Myjar.jar depends on everything else, it should be put at the end of the list. The other common mistake is to put spaces or paths with the JAR file lists.
