Sign out options

[yathish.venkatesh]

Isomorphic,

is there are any ways to achieve sign out/log out the session using smartGWT API's(server API's)? I need to clear all cookies associated with the session and redirect to my login screen..

Direct me to closest solution to achieve my needs...

Thanks,
Yathish

You can only clear cookies in the context of an httpRequest from the client. The core servlets APIs have the APIs necessary to clear cookies.

Ok. This is same with Singout/Logout? or are there are any gwt/smartGWT specific API's?

If that is the case, we have to call a DMI on click of that label.. Any other ways?

[Isomorphic]

A server call is required as previously noted. A DMI from a label is one of many options, but yes, that's a typical approach.

Isomorphic,

How can i access httpRequest object at server side? Can you please share one sample?

I need to clear the cookies and redirect to other URL when i click on logout label.... I am lost in my flow.

i called a DMI onclick of that label. But i am facing issues in how to achieve my tasks..

See the DMI overview - you can receive the HttpServletRequest object by just declaring it as a parameter of your DMI method.

Hi yathish,

I just did that. Here is my code:

server/ServletLogout.java

import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

@SuppressWarnings("serial")
public class ServletLogout extends HttpServlet {

	@Override
	public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
		request.getSession().invalidate();
	}

	@Override
	public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
		doPost(request, response);
	}
}

onClick:

RPCRequest reauthenticateUserRequest = new RPCRequest();
reauthenticateUserRequest.setActionURL("ServletLogout");
RPCManager.sendRequest(reauthenticateUserRequest, new RPCCallback() {
	public void execute(RPCResponse response, Object rawData, RPCRequest request) {
		Window.Location.reload();
	}
});

web.xml

	<servlet>
		<servlet-name>ServletLogout</servlet-name>
		<servlet-class>com.acme.myproject.server.ServletLogout</servlet-class>
	</servlet>
	<servlet-mapping>
		<servlet-name>ServletLogout</servlet-name>
		<url-pattern>/ServletLogout</url-pattern>
	</servlet-mapping>

Best regards,
Blama

I have used the same approach. Thanks for posting in detail which can be used by others too..
