I am trying to add a marker/icon on the vertical ruler in Eclipse. I used the following code for it
IEditorPart editor = PlatformUI.getWorkbench()
.getActiveWorkbenchWindow().getActivePage().getActiveEditor();
IFileEditorInput input = (IFileEditorInput)editor.getEditorInput() ;
IFile file = input.getFile();
IProject activeProject = file.getProject();
IResource res = (IResource) activeProject;
IMarker m;
try {
m = res.createMarker("com.examples.problem");
m.setAttribute(IMarker.LOCATION, offset);
m.setAttribute(IMarker.MESSAGE, "Hello");
m.setAttribute(IMarker.LINE_NUMBER, offset);
} catch (CoreException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
Where offset is the line number where I want the marker. This piece of code the a marker but not on the ruler, but on the Problems view next to Console and Error log. Any idea how I can fix it? Also if there is any other way of adding a toggle/icon/marker on the ruler, please advice.

You should use markerAnnotationSpecification extension point. This is used to define a mapping between markers and editor annotations automatically, with specified formatting.
See my blog post for more details about it: http://cubussapiens.hu/2011/05/custom-markers-and-annotations-the-bright-side-of-eclipse/

You should create the marker on the file that is open in the editor, not on the project.
