Errors when starting Java ME SDK 3 - Windows 7 x64

Question

Hi,
I am having trouble running the Java ME SDK 3 on a Windows 7 x64 computer. When trying to run the installed SDK using the shortcut link on my desktop, I receive a number of erros such as

Does anybody know where this comes from? Is it an incompatibility with Windows 7 x64? I have installed the latest Java SDK for Win64.
I have another issue consisting in the fact that the Eclipse MJT plug-in is not abel to find any devices in the Java ME SDK 3 folder (see my post in the Eclipse forum [Post in Eclipse MJT forum|http://www.eclipse.org/forums/index.php?t=msg&th=156515&start=0&S=6f25cc6925ad7008453ee93ca55525a2]), does this have anything to do with the problem described above?
Thanks for your help,
Markus

Answer 1

Edit file "C:\Java_ME_platform_SDK_3.0\bin\java", replace the path of x64 jdk by path of x32 jdk.
For example, my file contains "C:\Program Files\Java\jdk1.6.0_21" and I change to "C:\Program Files (x86)\Java\jdk1.6.0_21".
You need have a 32 bits jdk installed. Restart device managar after the change.
Obs.: This happens because device manager need load a 32 bits DLL. So you need run they with a 32 bits jdk.
With this method you don't need remove x64 jdk. You can stay with both jdk.
