My suggestions would be uninstalling/reinstalling Java. As someone said 7 has been buggy so sticking with 6 could be better.
Restarting the computer
Checking you have the right version of Java. Issues crop up between having a 64-bit OS and a 32-bit Java. I get both to save problems.
Restoring the computer back to a point where it worked.
It looks as if the Java Virtual Machine can't find a class called main, which every java program has to have.
"Exception in thread "main" java.lang.NoClassDefFoundError: fx" Actually I should clarify in saying it can't find where it's declared exactly. That line is the key line that's contains the error that's throwing everything out.
As for solutions, I'm not sure but hopefully I've helped you to understand your problem.

(This looked way better when typing it. its supose to be the error pop up box)
and it doesn't even open up minecraft. It started when the 1.5 minecraft update came out. when 1.5 came out, that message popped up most of the time but if i either rebooted the computer or after many times trying to open up minecraft i would maybe get lucky and it open, but it still didn't update. i borrowed my friends .minecraft file and that's how i got 1.5 but the JVML error kept popping up. when 1.5.1 came out i cant get minecraft to open what so ever. iv tried uninstalling and re-installing minecraft many times. same thing every time. Iv tried using different launchers, i.e. Technic launcher - vanila, to do it and same problem. Iv even tried to launch tekkit or technic or even voltz and same problem. Iv tried to play it in the browser mode at minecraft.net and the cant update error pops up. iv tried uninstalling and re-installing java many many time. same problems. i don't know what to do. iv checked to see if there are any viruses and there are none at all.
This is not an upgraded windows 7 to windows 8 laptop. this laptop came with windows 8 from factory.
Anyone can help me please?
Java 7 is a virus! the virus alters your virus software if it doesnt know that it is a virus meaning if you haven't updated it. it was actually causing mine to not upgrade at all. after i got around it, it deleted it. i installed java 6. everything works perfectly now 100%. if u havnt updated java yet from 6 to 7 dont do it. Again Java 7 is a virus.
You used MCPatcher? that must of caused your minecraft to explode go to MCPatcher and there should be a unpatch button it might start working after that I'm guessing it was working before MCPatcher screwed up minecraft not sure if that's the prob though
"Could not create java virtual machine"
I have updated to the newest version of java, I have uninstalled java and re installed java and even downgraded to 1.6.0_45 and I still get the same error.
Java debug gives no errors with 1.6 or 1.7.
I tried using MagicLauncher and I get this error:
java.lang.ClassNotFoundException: net.minecraft.client.Minecraft
at java.net.URLClassLoader$1.run(Unknown Source)
at java.net.URLClassLoader$1.run(Unknown Source)

at magic.launcher.Launcher.main(Unknown Source)
This pc has Win XP and only has 1g Ram so not sure if that is the problem.
I have tried running it through the .bat file and it does the same thing.
Any help would be appreciated...
any more suggestions
