I created a web site where several pages have applets embedded. I'm running Windows2K here at home as my development platform. When I view the webpages with the applets on my own machine they load just fine. However, when I go to other computers that are running WindowsXP Pro, Internet Explorer begins to load the page with the applet then crashes. An error log gets placed on the Desktop by HotSpot that states an EXCEPTION_ACCESS_VIOLATION. I don't get it. Would someone please help. It is critical that I get a solution to this problem.
The full error log is below. The following line in the log is in reference to the class I built: 0x0fa66460 JavaThread "thread applet-mvcs.TableForm.class" [_thread_blocked, id=2572]
It says _thread_blocked, why? Why would the thread be blocked. Would that have anything to do with the fact that I was behind a firewall when trying to access the webpage?

Alan, can we get more information about which jdk you are using to develop your applet? i would suggest trying to run your applet with jres older than 1.5.0_06 (it might have flaws you know, i had problems with this particular jre myself) that's one thing, another thing you might consider is to try to build a very simple applet (maybe some code is causing the crash, but really that is unlikely) for example that only displays some output statement, isolating the classes is a good idea always so that you know what is the real cause of crash, is it compatibility issue ... Maybe it's a display issue, since if i noticed correctly, it involves AWT... This is what i can think of at the moment... Best, Mohammad

Here's an update. I tried loading the webpage in three other seperate locations, one at Futureshop, second at the Sony store, and third at our local Xerox business where my wife works. In all three locations they have the latest jre and the applet loaded just fine. I have a sneeky suspician that this has something more to do with firewalls. Do you think that is a valid assumption? Do you know of any incompatibility issues or bugs with WindowsXP Pro regarding this issue?
