Java的浏览器兼容性问题

Question

Java Compatibility

I have been having some trouble with making a custom browser I am using a default class provided by oracle for a custom browser. One thing I noticed with the browser is that it cannot run java applets without some sort of variation of java browser plugins. How exactly do normal browsers receive information from a web server to run a java program externally? Is there any way to somehow point the browser toward the jre to run the app like on a normal browser. Just need somewhere to start. FireFox apparently references some sort of MIME format under the npjp2.dll native found in the jre directory. Thanks Very Much.

Answer 1

You can provide the user with a standard html download page in order for him to download a JNLP file which is the standard file to start a java web start app (applet). If the user's system has java installed, it must recognize the .jnlp file and assosiate it as a java app. It's an extra step, for the user to manually download the file instead of running automatically on a web browser, however because of recent security loopholes on java web implementations, most browsers don't trust java anymore, therefore the blocking. If you insist on setting up a web start app in a browser you must make sure that all users have appropriate security configurations on ther java installation (very unlikely).

EDIT:

Here's a very nice tutorial on how to achieve what I just explained.
