Just like the title says: Why do I get java.lang.reflect.InvocationTargetException in browser but not in eclipse applet viewer? When I run my applet (yes, i know applets are outdated) in the browser using html to load it, i get the java.lang.reflect.InvocationTargetException error. I read that this happens when the HTML is trying to load something that is not an applet, but it works when I run it as an applet in eclipse (brings up eclipse java applet viewer and works perfect...that is what stumps me). Here is the stack trace:
