How can I check if I have that java 6 plugin 2 for applets installed?

问题

Also, is creating an applet that uses the java 6 plugin 2 thing any different than creating a normal applet?

回答1:

See the Java documentation for the Applet and Object tags. Especially look at the documentation of the "class ID" attribute of the object tag. You want to use a classid tag like this:

classid="clsid:CAFEEFAC-xxxx-yyyy-zzzz-ABCDEFFEDCBA" 

where

xxxx = 0016
yyyy = 0000
zzzz = 0002

and this will specify that exact version. No, specifying any specific Java version is no different than asking for the "latest version intalled" except for the value of the classid attribute and perhaps the value of the codebase attribute.

See also Deployment Advice from Java 6 update 10. Note that Java 6 update 10 adds a number of significant features that allow you, for example, to run an Applet outside of a browser.
