Need to get filename from custom extension

Question

Hello,
I am currently writing a custom extension and I'm having a tough time trying to get the filename of the document (java file) of the currently selected (and opened) file. So I have a java file open and right click on it to launch my extension. How do I get information on that document?
Also is there javadocs for the extsnsion API's? If so where are they located.
Thanks in advance!
Bill

Hi Bill,
You can find javadoc on the extension API via the help system (JDeveloper Extension SDK topic under the Reference section). Alternatively, you can extract the contents of the ${jdevhome}/jdev/doc/ohj/jdev-doc.jar to a directory somewhere to view the javadoc in a browser.
To get the filename of a document, assuming you're using 10g (not much different from 9.0.x), you need to get an instance of oracle.ide.addin.Context. Normally, you'll have a Context instance because you're implementing your logic in a Controller or a Command subclass. If not, you can obtain one using:
Ide.getMainWindow().getLastActiveView().getContext()Once you have the context, you can get the current selection from it. If that selection implements oracle.ide.model.Locatable, it has a URL. From the URL, you can get the filename:
import oracle.ide.model.Element;
import oracle.ide.model.Locatable;
import java.net.URL;
import oracle.ide.net.URLFileSystem;
Element[] selection = context.getSelection();
if ( selection != null )
  if ( selection[0] instanceof Locatable )
    URL url = ((Locatable)selection[0]).getURL();
    String filePath = URLFileSystem.getPlatformPathName(
      url
}One final thing, if the current view is an editor, the selection may be empty or will not contain Locatables. If that's the case, you might want to get the Document from the Context instead. I.e.:
URL url = context.getDocument().getURL();
String filePath = URLFileSystem.getPlatformPathName(
  url
);Thanks,
