HTTP Servlet

-
In today's post I will share about the advancing with  servlets in the earlier post we have studied about the Generic servlet  and http servlet what else with http servlet can be done will see today in this post, Http servlet is the sub class of Generic servlet and we have seen that in generic servlet has declared service method as abstract and Http is derived from Generic servlet so definitely service method is to be defined in it. Besides service method two more methods have been defined in Http servlet and they are doget and dopost  they are defined as

public void doget(HttpServletRequest req,Http ServletResponse res)
{

}

AND

public void dopost(HttpServletRequest req,Http ServletResponse res)
{

}

These two methods are very much useful these two methods are used to catch our request from our normal Html forms generally when we click on submit button we are requesting either by post or get that means either we are sending information or requesting through get or post method so For that if we are programming through servlets we have to define the either dopost or doget method so it can handle request which is requested by a normal form.

In dopost or doget you can write anything generally in register form we have to input data in the database so can establish connection and can fire insert query for all records you want to insert in database.

State space search / blocks world problem by heuristic approach /TIC TAC TOE

-
A lot of AI is about SEARCH. The "state space" is the set of states of the problem we can get to by applying operators to a state of the problem to get a new state. A  state  contains  all of the information necessary to predict the effects of an action and to determine if it is a goal state. State-space searching assumes that the agent has perfect knowledge of the state space and can observe what state it is in (i.e., there is full observability); the agent has a set of actions that have known deterministic effects;some states are goal states, the agent wants to reach one of these goal states, and the agent can recognize a goal state. a solution is a sequence of actions that will get the agent from its current state to a goal state. Define the Problem as State Space Search Consider the problem of “Playing Chess” . to build a program that could play chess, we have to specify the starting position of the chess board, the rules that define legal moves. And the

Navigation in Vaadin.

-
Plain Vaadin applications do not have normal web page navigation as they usually run on a single page, as all Ajax applications do. Quite commonly, however, applications have different views between which the user should be able to navigate. The  Navigator  in Vaadin can be used for most cases of navigation. Views managed by the navigator automatically get a distinct URI fragment, which can be used to be able to bookmark the views and their states and to go back and forward in the browser history. The  Navigator  class manages a collection of  views  that implement the  View  interface. SO the class in which you are defining Navigation must implement with a  View  interface. addView() i s the method by which you can register Your View . You can add your view at any point ,Your View must have   name identifier and be added to a  View . Once registered, you can navigate to them with  navigateTo() . Navigator  manages navigation in a component container, which can be
