I found code copy with similar functions on the Internet and modified it. So I posted it and took a note...

 

Index. jsp

String Path = request. getcontextpath ();
String basepath = request. getscheme () + "://"
+ Request. getservername () + ":" + request. getserverport ()
+ Path + "/";

String name = NULL;
String pass = NULL;

Cookie [] cookies = request. getcookies ();
For (INT I = 0; cookies! = NULL & I <cookies. length; I ++ ){
If (Cookies [I]. getname (). Equals ("user ")){
Name = Cookies [I]. getvalue (). Split ("-") [0];
Pass = Cookies [I]. getvalue (). Split ("-") [1];
}
}
If (name = NULL ){
Name = "";
}
If (pass = NULL ){
Pass = "";
}
