Thanks.

PROBLEM :

1) I Have created an editor by extending EditorPart.

2) Now I want to implement undo action exactly similar to the Eclipse.

3) In ApplicationActionBarAdvisor,

I have I have created an action by writing following codes,

// Inside makeActions() method.

IWorkbechAction undoAction=ActionFactory.UNDO.create(window) ;

register(undoAction);

// in fillcoolbar() method I have added this action.

toolBar.add(undoAction);

Above written code is providing an icon in the toolbar but this is always disabled.

But same steps did work for implementing "Save Action"

I know there something different which I dont know. because "Undo" is gonna be a retargetable action. will anyone help me urgently to solv this problem.I'm really in a critical situation.

Thanks in Advance

You also need to retarget the undo (and redo) actions. See
AbstractTextEditor.createUndoRedoActions() for how this can be achieved.
