disk cache for JAR files when running plugin

[Phillip Gardner]

I am working on an applet which will run under the Java plugin (and JRE1.1.7B). Our JAR file is fairly large; so, it would be nice if the plugin did not have to reload the JAR file every time. There is a memory cache which works if you revisit the page without restarting the browser. Is there a way to cache the JAR file on disk so that it does not have to be reloaded if you do restart the browser?
Thanks for any help you can give!
Regards!
Phil

I remember at the Java Summit there was talk about that, but no particulars. I just relayed your question to their mailing list in hopes for details.
I guess the problem is that the caching is screwed up in both browsers, but there is a way to fix it.
Will let you know what I find out.

Please refer to Java Developer Connection, Question 551 for details.

You can copy a jar file to a local browser if you are using a signed applet. Please refer to java.util.jar package for functions, JarInputStream, JarOutputStream.
If you are using an unsigned applet, the jar files must reside locally. One way to get them there is to have your web server serve the files via the browser "Save As File" function.
