error in midlet while implementing command

import com.sun.lwuit.Command; import javax.microedition.midlet.; import javax.microedition.lcdui.;

in my code but still the following errors are coming...

exitCommand = new Command("Exit", Command.EXIT, 2);  //line 1
 textbox.addCommand(exitCommand);                     //line 2

Command.EXIT cannot be resolved..

The method addCommand(Command) in the type Displayable is开发者_如何转开发 not applicable for the arguments (Command)

There is no constructor to pass like this. Try to learn LWUIT and see this linkfor your reference. You can't use LWUIT command for J2me textbox.

You are importing LWUIT Commands, but using the LCUID Command methods. Your code would be right if you were importing javax.microedition.lcdui.Command;. But if you want to use LWUIT components, you have to forget about Items and moreover Item Commands.

I don't know if it's agood idea to mix LCUID and LWUIT, but well, I haven't used it, so I can't really say.
