You need to add an org.eclipse.ui.editors extension point.

 <extension point="org.eclipse.ui.editors">
  <editor
        name="MyEditor Name"
        extensions="my_file_extension"
        icon="icons/sample.gif"
        class="com.me.MyEditor"
        id="com.me.MyEditorID">
  </editor>

You have written your own editor? Or do you want to use some default editor? – Pushkar Jan 17 '13 at 09:08

Well if you have your own viewer implementation you will need to define the complete behavior in that viewer, even the opening of files. Since you have registered an editor against that extension so whenever that file is opened in Eclipse, either by your viewer or some other viewer (Project Explorer, Navigator) Eclipse will automatically open the file in the assigned editor.

In your double click listener you can use org.eclipse.ui.actions.OpenFileAction or something like it to ensure that the file is opened by Eclipse according to Workbench rules. Btw why do you want to avoid adding a double click listener?
