Hello Daniel,
I finally made it like this:
IWorkbenchPage page =
PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActi vePage();
HashMap<String, Object> map = new HashMap<String, Object>();
map.put(IMarker.LINE_NUMBER, new Integer(lineNumber));
map.put(IDE.EDITOR_ID_ATTR, "org.eclipse.jdt.internal.ui.javaeditor.JavaEditor");
try {
IMarker marker = file.createMarker(IMarker.TEXT);
marker.setAttributes(map);
IDE.openEditor(page, marker);
marker.delete();
} catch (PartInitException e) {
e.printStackTrace();
} catch (CoreException e) {
e.printStackTrace();
}
Is that a good practice?
Also, to obtain the IFile based on the name of the Java class I want to open, I had
to use org.eclipse.jdt.internal.core.JavaProject and
org.eclipse.jdt.internal.corext.util.JavaModelUtil, which are internal classes. Is
there a way to do that task without calling these classes?
Thanks,
Sébastien

It is OK if the editor isn't a text editor. In your case it is and hence
you should use:
if (editor instanceof ITextEditor) {
((ITextEditor)editor).selectAndReveal(offset, length);
return;
}

What do you know from that class? Just the name? The file's location?

Ok, it works perfectly now, thanks! :)
I have another question, since we're on the subject of discouraged dependencies:
I want to get or create a JavaStackTraceConsole, set its content and show it to the
user. Up to now, I had to create one (hence the discouraged dependency) and add it to
the console manager, since when I call the console manager's getConsoles() method no
such console is returned.
Do you know of a best-practice way to create or retrieve such a console, set its
content and display it?
Thanks for your help,
Sébastien
