This is the error that I get when I try to use an applet to upload a pdf document in salesforce platform.While I try this in html environment,it works perfectly.Thinking that the version of the jre is different I checked it out with both class files of 1.5 and 1.6.Do i need to look for jre 1.4 too???

My general problem is that I need to get files uploaded from a VF page that I have prepared.All the apis from Salesforce have been used.I package it in a signed jar.Then when I integrate it with my VF page I get this error!!!
