How to use system clipboard in Asha 305

[ayamadori]

I'm trying to test com.nokia.mid.ui.Clipboard in the emulator of Nokia SDK 2.0 for Java and Asha 305.
But both throw java.lang.IllegalAccessException.
Test code is below.

import com.nokia.mid.ui.Clipboard;
...
try {
   Clipboard.copyToClipboard("test");
} catch (Exception e) {
   System.out.println(e.toString());
}

And the same code work fine in C5-03(S60 5th).

I think this is because Asha 305 does not have the function of copy/cut/paste,
but Clipboard API should be valid in Nokia UI API 1.6. Hmm...

So please give me advice.
