Marker doesn't show up.

[kaprasanna]

Hi,

In order to set a marker to a particular line of a file, I have written the following code but the marker doesn't show up.

    IFile = getFirstFileFromProject();//an utility method that gets into the 'src' folder of the project then recursively finds all java files from folders and returns the first file

    IMarker marker = null;
	try {
		marker = file.createMarker(IMarker.PROBLEM);
		marker.setAttribute(IMarker.MESSAGE, "My message");			
	} catch (CoreException e1) {
		e1.printStackTrace();
	}

I tried to call

MarkerViewUtil.showMarker(page, marker, true);

but that did not work. Failed with following exception : java.lang.NoClassDefFoundError: org/eclipse/ui/views/markers/MarkerViewUtil despite all the jars present in the classpath and dependencies.

Please guide.
Thanks.
