Hi, I have a really essential question about SDKs and OSs.
Is it possible to create application for OS 5 with the SDK 6.
I think it isn't possible with SDK 7 because it's based on qnx systems, isn't it?
But how can I find out whats the right SDK version. Is the SDK version corresponding to the OS major version? Can I run my SDK 5 applications on OS 7/qnx?

BlackBerry OS is forwards compatible. This means if it works on an older OS, it will work on a newer OS.
So an app built with 5.0 will work on 5.0, 6.0 and 7.0. An app built with 7.0 will only work on 7.0 (right now).
You cannot make an app with 6.0 and have it run on 5.0, even if you only use 5.0 classes.
Also, 7.0 is not QNX based.

Can you please explain how you installed applciation on device?
Problem you faced its seems to happen when you used third party jar file in application but not installed it with aplicaton in device.
Please search about UpdateJad tool to merge multiple code file.
