The jsp page sends a delete request to the struts action that determines whether or not the object associated with the node can be deleted from the database. The struts action removes the object from the database if all is well, and at this point, I would like to have the struts action notify the jsp that it can remove the node from the tree. Is there a way to set it up so that the jsp page gets a return value from the action and javascript within the jsp page removes the node accordingly?
