My test case looks like following
#RunWith(SWTBotJunit4ClassRunner.class)
public class ExitHandlerTest {
private static SWTBot bot;
#BeforeClass
public static void beforeClass() throws Exception {
bot = new SWTBot();
}
#Test
public void testExitHandler() {
SWTBotMenu fileMenu = bot.menu("File");
Assert.assertNotNull(fileMenu);
SWTBotMenu exitMenu = fileMenu.menu("Exit");
Assert.assertNotNull(exitMenu);
exitMenu.click();
}
#AfterClass
public static void sleep() {
}
}
Code for my exist handler is
public class ExitHandler {
#Execute
public void execute(IWorkbench workbench, EPartService partService, ISaveHandler saveHandler) {
workbench.close();
}
}
Although the test run fine but I am not sure why am I getting this exception.
Looks like you have the e4 live model editor included in your test and you are hitting Eclipse bug 426373.
I don't think this is actually affecting your test so you can ignore it.

Exception running application PlayVideo.Main
I also checked this link on stackoverflow but couldn't find solution. Link
Also tried it this way but video won't load.

webview.getEngine().load(

I have a keyboard emulation class which has a method to type to the Eclipse editor automatically based on voice recognition input. This works correctly.
I also have tables made in JavaFX, in which a user clicks an element and it too is emulated to the screen using the same method.
However, I am getting "Exception in thread "JavaFX Application Thread" java.lang.NullPointerException" exceptions. This does not happen from the voice recognition part, only when the JavaFX thread calls the method to update the Eclipse editor.
Keyboard Emulation method which prints data to the eclipse text editor
private void doType(int[] keyCodes, int offset, int length) {
if (length == 0) {
return;
}
//Since we are in a loop, we must only emulate the mouse press on the eclipse
//text editors last known location to avoid every letter getting mixed up
correctCaretPosition++;
Display.getDefault().syncExec(new Runnable() {
public void run() {
System.out.println("fwefwefwef\n\n\n\n\n\n" + myEditor.PROP_DIRTY);
Control control = myEditor.getAdapter(Control.class);
//Only when the click to bring eclipse into scope has not happened
if (control instanceof StyledText && correctCaretPosition <= 1) {
StyledText text = (StyledText)control;
// Position of caret relative to top left of the control
Point relPos = text.getLocationAtOffset(text.getCaretOffset());
// Position relative to display
Point absPos = text.toDisplay(relPos);
System.out.println(absPos.x + " " +absPos.y);
robot.mouseMove(absPos.x, absPos.y);
robot.mousePress(BUTTON1_MASK);
robot.mouseRelease(BUTTON1_MASK);
}
robot.keyPress(keyCodes[offset]);
doType(keyCodes, offset + 1, length - 1);
robot.keyRelease(keyCodes[offset]);
}
});
}
JavaFX call to Keyboard Emulation
Platform.runLater(new Runnable() {
#Override
public void run()
{
robot.type(data);
}
});
The error comes from this line
Control control = myEditor.getAdapter(Control.class);
Robot in this context is the Keybooard Emulation object.
Am I getting the concurrency between the two completely wrong?
UPDATE:
The root of the error is
Control control = myEditor.getAdapter(Control.class);
I passed in the control from the beginning of the application, no error, however, nothing happens as I believe the control does not satify
if (control instanceof StyledText && correctCaretPosition <= 1) {

}
public void onModuleLoad() {
initMap();
}
private void initMap() {
MapOptions defaultMapOptions = new MapOptions();
MapWidget mapWidget = new MapWidget("684px", "330px", defaultMapOptions);

lonLat.transform("EPSG:4326", "EPSG:900913");
map.setCenter(lonLat, 12);
RootPanel.get().add(mapWidget);
}
Does anybody know how to solve this problem?
After some research I can tell you that osmarender as well as maplint are not supported anymore: http://wiki.openstreetmap.org/wiki/Tiles#home
If you delete those to layers from your function (osm_1 and osm_4) everything works perfectly.
what is the wrong in my code..

RootPanel rootPanel = RootPanel.get();

You need to add #RemoteServiceRelativePath("some.path") to you interface.
See this tutorial.
When running your RPC call, development mode displays an exception NoServiceEntryPointSpecifiedException: Service implementation URL not specified. This error means that you did not specify a #RemoteServiceRelativePath in your service interface, and you also did not manually set target path by calling ServiceDefTarget.setServiceEntryPoint().
ServiceDefTarget target = (ServiceDefTarget) yourService;
target.setServiceEntryPoint(GWT.getModuleBaseURL() + "yourpath");
Also note this one that's closely related to above one,
If invoking your RPC call fails with a 404 StatusCodeException, your web.xml may be misconfigured. Make sure you specified a #RemoteServiceRelativePath and that the specified in your web.xml matches this value, prepended with the location of your GWT output directory within the war directory.
For every annotation definition given above, corresponding entry for service impl should be given in web deployment descriptor i.e web.xml. As an example,
<servlet>
<servlet-name>sampleServlet</servlet-name>
<servlet-class>samples.gwt.SampleServiceImpl</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>sampleServlet</servlet-name>
<url-pattern>/sample-gwt-module/sampleService</url-pattern>
</servlet-mapping>
where
sample-gwt-module
is the (alternate) name of the sample GWT module as defined in module definition as
