OpenJDK doesn't work with some web apps

[Peter McKenna]

OpenJDK Web Start would not work with FXTrade applet at www.oanda.com. The applet loads normally, but then can't seem to connect to the server. I tried clearing the cache with no effect.
On the Oanda web site there is also a desktop version of their FXTrade interface. This worked with OpenJDK but did not really install properly since no desktop configuration file was created.
After completely uninstalling OpenJDK and using java-6-sun, both versions of the app worked perfectly.
Hopefully this info is helpful to someone who knows a bit more about Java than I do!
My Platform is Ubuntu 8.04 with Firefox 3 Beta 5.

A bit of further investigation on the Oanda web-site revealed that they started using signed applets on the 13 of March. Could this be the problem?

this works for me with 6b12~pre2-0ubuntu2 in intrepid (at least with the applets I could find on this page)
