Session ID not the same in my java ee application -

-

I wrote an application with a custom login system, and then wrote my own security filter for that which Sets the area that can be accessed. However, I am always redirected to the login page and then on the index page with the log in the home page. I have found that session ID is different when I try to use the thing which is restricted when I login. Here is my code: 

  Public class securitizer tool filter {Public Zero Init (FilterConfig filterConfig) throws ServletException {// Use the file to change the body of the implementation methods. Settings | File templates} Public Zero doFilter (ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException {HttpServletRequest req = (HttpServletRequest) servletRequest; // If there is no user, they have not gone via // login, then kick them on the long page if (null == req.getSession (). GetAttribute ("user name")) ((httppservate Response) Servlet Response) .seendRedirect ("../ Login.jsp"); System.out.println ("Redirected - No Session"); } // Otherwise, let them go to Page / Resources, they want Chain.doFilter (servletRequest, servletResponse); System.out.println ("went through the filter"); // System.out.println ("Filter Servlets:" + req.getSession (.) GetId ()); } Public Zero Destroy () {// Use the file to change the body of the implementation methods. Settings | File templates}

}

My web here The Xml file is: 

  & lt; Filter & gt; & Lt; Filter-name & gt; SecurityFilter & lt; / Filter-name & gt; & Lt; Filter range & gt; Filters.securtityFilter & lt; / Filter range & gt; & Lt; / Filter & gt; & Lt; Filter-mapping & gt; & Lt; Filter-name & gt; SecurityFilter & lt; / Filter-name & gt; & Lt; URL pattern & gt; / Add / * & lt; / URL pattern & gt; & Lt; / Filter-mapping & gt;

So if anyone can help me with this problem please tell me if you would like code now thank you in advance

In your login service you have 

  while (Rsnext ()) {Https session session = request.getSession (true); String tmp = rjest string (1); Println (tmp); Session.setAttribute ("user name", tmp); Count ++; }

So if your session does not have a username, it is because this code block is not being executed. I think that you are looping through the results of a database query, so check that the actual query that you are performing returns any results.

c# - ListView onScroll event -

-
I am programming a simple C # application, and I need a Scallow event on the list view. So I inherited the original ListView class created in ListviewEx witch. I found out how to locate the scroll message from WinAPI and I modified the WndProc method. Now I have this WndProc: protected override zero WndProc (Ref message message) {base.WndProc (Ref I); If (m.msg == WM_VSCROLL) {onScroll (This, New EventArgs ()); }} But the problem is, I do not know how to know about scrolling information. This data should be in wParam, but there is a LOWORD macro ++ like in C in C # and I switch to find the criteria like SB_ below, SB_ENDSCROLL, SB_PAGEUP etc. there any way Need to change the LOWORD macro from C #? Or any other way to find the necessary parameters about scrolling? You can define the WParam constants as the following: Private const int WM_HSCROLL = 0x114; Private Constant WM_VSCROLL = 0x115; Private contact int SBHOZZ = 0; Private Consultant SB_VERT = 1; Private Con...

Linux Terminal Problem with Non-Canonical Terminal I/O app -

-
I have a small app written in C to run on Linux. Part of the app accepts user-input from keyboard , And it uses non-canonical terminal mode so that it can respond to each keystroke. The section of the code that accepts input is a simple task that is called repeatedly in the loop: char get_input () {char C = 0; Int res = reading (input_tamille, & amp; c, 1); If (RSS == 0) 0 returns; If (res == -1) {/ * snip error handling * /} return c; } It reads a letter from the terminal if there is no input within a given time limit, (c_cc [VTIME] value in the vocabulary structure), read () 0 And get_input () is called again It all works very well, I have recently discovered that if you run this app in a terminal window, and then the app Close the terminal window without ending, the app will not exit Received, but CPU intensive launches into an infinite loop, where the read () returns 0 without waiting continued. So how can I get out of the apple if it runs from the terminal win...
