Question: I am developing a plug-in.

On clicking a button, I'd like to call the save method of Eclipse or call the save button on Eclipse toolbar.

What is the way to do it?

Answer: 
```
org.eclipse.ui.PlatformUI.getWorkbench().saveAll(..) 

```

should do the trick.

If you want to save the active editor, please try

```
IWorkbenchPage page = PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActivePage();
IEditorPart editor = page.getActiveEditor();
page.saveEditor(editor, true /* confirm */);

```

Note that the elements in the navigation path may be null.
I used -

```
IDEWorkbenchPlugin.getDefault().getWorkbench().saveAllEditors(true);    

```
