What kind of exceptions are you seeing? One thing that differentiates appletviewer from a real browser is that appleyviewer does not enforce any of the security restrictions that apply to applets. So if the applet does something forbidden, security exceptions would be thrown in the browser, but not in appletviewer.

so how can I check what exceptions are being thrown?
sicne not only my code cannot display applets in browser but apparently other websites as well, I think it might be the blocker software in my company causing problems
Even I am facing a similiar issue. I have Windows XP and JRE1.5 installed in my PC. I tried accessing http://www.javaranch.com/game/game2.jsp. Instead of applet I get a X symbol on the top left corner. Then I uninstalled JRE1.5 and Installed JRE1.3 I get an error message saying "java.lang.ClassNotFoundException:javaranch.roundup.applets.QuizApplet.class Please help me resolve the issue.

Exception are logged in the Java Console. But you said that a NPE was thrown, so you already know where to look for them.
