Any one know what is wrong here? I have seen this error before with other java projects. What is the problem and the fix? Just in case this is on Windows XP current on service packs.

Thanks

Please dont cross post. Its not nice and we know you want a fix, there just isn’t a need…
You have compiled the classes with the 1.5 (or 5.0) JDK and ran them on a 1.4 JDK.
Btw, how is this related to troubleshooting jme? You could have posted this on the java forums instead of the jme forums… oh well, its done now.

a little education please, but what is the point of compatibility options if they dont work. I set code to be 1.4 compatible with 5.0 and tried to run it on a 1.4 jre and have it complain and crash it even happens with 1.4 to 1.4..... I don't understand, I can be a little dim, but doesn't these issues complicate deployment.
umm…eclipse problem perhaps?
Its working fine over here…

perhaps… for my code,
but I encountered 1.4.2_07 to 1.4.2_03 on a downloaded game once,
when you have hardware issues and platform consideration headaches to think of, and then you’re faced with the prospect of doing something that a particular vm doesn’t support especially when simply doing stuff for fun and hobby and just want to share, it can be a turn off. not a jme rant, a general one
Thanks for the input about the version. I found a space in the path to my JRE and it was defaulting to 1.3.1.02. corrected that problem by removing the space. Now I am having problems with the display. here is the current error.

I suggest you to download and install the newest drivers for your graphicscard.
Hopiu
I still have the same last problem. Some think it is a video driver issue. I have a intergrated Intel 82815 /G/EG Solano Graphics B0-step Controller(microsoft). Will this work with the current jme? if not what video card do I need to run jme?
I’m no expert, but your card may not support opengl, you need it to use jme.
as for cards I’m a nvidia fan there opengl is good real good
At work I’ve got a 82865G and it does not work with jME, so it is quite likely that your’s does not work, too.
