Re: Custom session is null
I have bookmarkable pages for the login and the form page. Now I go to the form page If you using a link to go to form page, for some reason you don't get an cookie on your browser holding your session information. If you just writing the url to form page on browser, you are not passing session information encoded on url because it is bookmarkable. which implies that the URL will not have any session information encoded in it, and that you can call this page directly without having a session first directly from your browser http://cwiki.apache.org/WICKET/bookmarkable-pages-and-links.html On Thu, Oct 1, 2009 at 10:47 AM, Stephen Nelson step...@eccostudio.comwrote: Hello Wicket Users, I'm a beginner to wicket having previously used Spring MVC and Struts 1/2 so definitely from the other side as far as web frameworks go! Anyway I have a custom session to store a logged-in user; a panel component which performs the login; and a form web page. I'm using Wicket 1.4.1 on Glassfish 2.x and Spring 2.5.6 to hook it all together. I have bookmarkable pages for the login and the form page. Anyway when I deploy the app I go to login. This works fine and I have logger statements when storing the user in the session. Now I go to the form page, which after clicking submit, checks if you're logged in. This test fails and I'm asked to login. If I now do a further login I can return to this form page and it functions as expected. I'm not sure why this session object is null the first time around. If you want me to provide a few code snippets I can.

You are correct - I just added a link component on my login page to my form page and it now functions as expected. However I don't quite follow why it doesn't work when manually typing a url in. If I'm logged-in I would expect to stay logged-in whether I manually type a url or follow a link. Which bit am I misunderstanding? -- Stephen Nelson - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Re: Custom session is null
The cookie used to keep session information. When you use link to access the form page, you are sending the session cookie stored on browser back to server, that now can to know with what session he has to work. Creates a cookie, a small amount of information sent by a servlet to a Web browser, saved by the browser, and later sent back to the server. A cookie's value can uniquely identify a client, so cookies are commonly used for session management. http://java.sun.com/products/servlet/2.2/javadoc/javax/servlet/http/Cookie.html On Thu, Oct 1, 2009 at 11:48 AM, Stephen Nelson step...@eccostudio.comwrote: On 1 Oct 2009, at 15:11, Pedro Santos wrote: I have bookmarkable pages for the login and the form page.

So long as the domain matches that of the cookie it will be sent every request. So I'm not sure of the difference between accessing the page directly, or accessing the page through a link. My session should be retrieved on each request. This is what I'm not understanding I feel. -- Stephen Nelson - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
