Replace ClassLoader with custom class loader in Java Plugin

[pwlodarczak]

Hi,
I want to replace the ClassLoader of the Java Plugin with a customized one in IE 6. I tryed to add the

-Djava.system.class.loader=CustomClassLoader

in the Java Control Panel but it doesn't seem to load this class loader.
I tried to put it in the same directory like the applet itself and also localy in the CLASSPATH, but no look.
There doesn't seem to be any documentation for how to do this.
Anybody knows how to do this?

Do you want to use IE plugin only?

So you can use the common applet run html code I guess...

you can read this HTML Applets - HTML Code Tutorial

I got it working by creating a modified sun.applet.AppletClassLoader, put it in a jar and added the jar at the beginning of the boot class path using

-Xbootclasspath/p:C:/<path>/cl.jar

in the applet configuration panel. May be this can save someone some time.

Could you explain where the applet configuration panel is?
Is it one of the tabs in the Control Panel for java?

[pwlodarczak]

Yes, it's the Java control panel, under Java Runtime-Parameter I have

-Xms256M -Xmx512M -Xbootclasspath/p:C:/<path>/cl.jar

Can you explain why you want change the ClassLoader with a local setting? I know that the classloader from the Appet and Java Web Start are not very good. We have also write our own application classloader.

But a local setting will interact with all applets that the bowser loads.

Basically we load many applets from different servers. They load the same jars. The customized classloader just makes sure these jars are shared and not loaded more than once. It will not interfere with other applets.
