I want to create a plugin similiar to the stamper plugin found in Acrobat sdk sample. Or create one more menu item below "Stamper annotations" and when clicked it should paste the text i defined.

That is it should work exactly similiar to the stamper plugin. I created the menu items in the plugin, but not to do the stamping.  Kindly help. How to go about it.
