how can solve that java.lang.classformaterror problem caused by my com

[ncd]

I am using java applet with microsoft com object. I use microsoft VJ++ create a wraper class of my com object, and use that in my java applet. But when I view my htm page in IE, it said java.lang.classformaterror. I add my project directory to javavm trustedclasspath setting in registry, then it works. But now I want to publish my webpage, not just run on my computer, how can I do now?
Thanks! [sig][/sig]
