Hi Avital,
when programming in Java, for most of the functionality you have API calls that work on ImageProcessor level and do not display anything, in contrast to the simple IJ.run(...) method. So, if possible, try to avoid Batchmode in plugins.
Also, using BatchMode in a plugin is a bit dangerous, if you plugin casts an exception and does not exit Batchmode, you may run into trouble.
If avoiding BatchMode is too cumbersome:
If an image has no window yet (because it was created in BatchMode), simply use imp.show() on the ImagePlus. If the image has a roi, you might also need the following after show for the roi to be displayed correctly
Roi roi = imp.getRoi();
if (roi!=null) imp.setRoi(roi);
Here you can find the full code how to display any image after BatchMode (no matter whether the image was created in Batchmode or already has a window):
