Unable To Create MIDlet Null

Question

hi all!
i am trying to run a simple midlet code and am egtting the error:
Unable To Create MIDlet Null
java.lang.NullPointerException
     at com.sun.midp.midlet.MIDletState.createMIDlet(+14)
     at com.sun.midp.midlet.Selector.run(+22)
I have tried to find out the solution but all my efforts have been in vain!
anybody who can help me please reply to my query as soon as possible!
your guidance will be appreciated!
The code is as follows:
package example.MethodTimes;
import javax.microedition.midlet.*;
* An example MIDlet runs a simple timing test
* When it is started by the application management software it will
* create a separate thread to do the test.
* When it finishes it will notify the application management software
* it is done.
* Refer to the startApp, pauseApp, and destroyApp
* methods so see how it handles each requested transition.
public class MethodTimes extends MIDlet implements Runnable {     
// The state for the timing thread.
Thread thread;
* Start creates the thread to do the timing.
* It should return immediately to keep the dispatcher
* from hanging.
public void startApp() {     
thread = new Thread(this);
thread.start();
* Pause signals the thread to stop by clearing the thread field.
* If stopped before done with the iterations it will
* be restarted from scratch later.
public void pauseApp() {     
thread = null;
* Destroy must cleanup everything. The thread is signaled
* to stop and no result is produced.
public void destroyApp(boolean unconditional) {     
thread = null;
     public void exitApp() {     
destroyApp(true);
* Run the timing test, measure how long it takes to
* call a empty method 1000 times.
* Terminate early if the current thread is no longer
* the thread from the
public void run() {     
Thread curr = Thread.currentThread(); // Remember which thread is current
long start = System.currentTimeMillis();
for (int i = 0; i < 1000000 && thread == curr; i++) {     
empty();
long end = System.currentTimeMillis();
// Check if timing was aborted, if so just exit
// The rest of the application has already become quiescent.
if (thread != curr) {     
return;
long millis = end - start;
// Reporting the elapsed time is outside the scope of this example.
// All done cleanup and quit
// destroyApp(true);
//notifyDestroyed();
          exitApp();
* An Empty method.
void empty() {     
Thanks!!

Answer 1

that is because the other projects created a package of its own. Thats no problem and not required for execution.
You have to do
1) create in your project's src directory a subdirectory called "examples" (if you want to use the package)
2) in this subdir (./src/examples/) you have to put the MethodTimes.java file which contains the code from above with the "package examples;" statement.
3) run the WTKs build and afterwards the run
This should work. If not, be plz more precisely on whats not working.
And the WTK 2.1 should be no problem at all since I used it too.
