Hi This should be an easy one (I hope)... Are there any compatability issues I should take in concern before developing an applet? E.g. what's the difference if the visitor uses Sun's JRE (old or new) or MS JVM? Thanks B
Netscape 4.7 (and older) and Internet Explorer (up to about 5.5) run using antiquated versions of Java - somewhere around release 1.02. The security system is more primitive and there's no Swing classes - just to mention two major issues. Additionally, Microsoft went and wrapped a whole raft of Windows functions in a set of classes that no other Java ever supported. However, Netscape 4.7 may someday die off (Mozilla and Netscape 6+ are much better, anyway) and newer IEs have no Java capacity at all. To make the newer Netscape/Mozilla and IE browsers run applets, you must download and install the Java Plug-In. As must all the applet's users. It only has to be done once, but it's a major problem, since the file is something like 1.5MB or more. Dial-up users with slow modems tend not to appreciate this, and even users with fast links often avoid installing plugins. Fortunately, Dell and HP/Compaq have started bundling Java with their newer computers. For maximum portability, then, code using only the old Java classes. However, if the power of a modern-day Java implementation is more important, use the Java Plug-In.
"privilege" comes from the Latin words for "private" and "law" (legal) and dates to feudal times. To "claim privilege" meant that you were above the laws that applied to the common people.
