Pl/sql web application login and logout problem

Hi, every expert.
I am making a web application with pl/sql, and I focus on the login and logout recently.
I make use of owa_cookie to login and logout, it works wonder in login process as the cookie values are sent to the page successfully, and cookie info was killed successfully when logging out, but the problem is when i click the back button on the browser it can still go back to the previous page, only if i refresh it again it can work propely

As far as I know, there is only Java API for managing the application. You might need to look into making some java web services to handle this.

How to make a login and logout in jsf 2.0 ?

Hello all, i am developing an web application have login and logout component. I want to check whenever end user try to open admin/index.xhtml, it will be redirected to login.xhtml. And when end user click on log out button, i will be destroy session and redirect end user to login.xhtml. But i am not sure about session in JSF 2.0. I am using netbean 6.9.1 to develop. First time, when i run my web application, i can get session back. But another time, i can't get session in my bean. Do i can use filter with JSF 2.0 to make a validate login user ? And any suggestion for my issue ? Thanks in advance!
Here is my filter with doFilter method:
RequestWrapper wrappedRequest = new RequestWrapper((HttpServletRequest) request);
ResponseWrapper wrappedResponse = new ResponseWrapper((HttpServletResponse) response);
if (wrappedRequest.getSession().getAttribute("isValidUser") != null) {
chain.doFilter(request, response);
} else {
goPage(wrappedRequest, wrappedResponse, "/faces/enduser/index.xhtml");
And here is my bean with login and log out method:
public String validUser() {
try {
if (iAccBO != null) {
Utilities utilities = new Utilities();
Account account = new Account();
account.setAccName(getAccName());
account.setPassword(utilities.encode(getPassword()));
if (iAccBO.validUser(account)) {
setAccName("");
setPassword("");
return "/admin/index";
} else {
FacesContext fc = FacesContext.getCurrentInstance();
fc.addMessage(null, new FacesMessage(FacesMessage.SEVERITY_ERROR, "invalid username or password", ""));
return "login";
} catch (Exception ex) {
ex.printStackTrace();
Logger.getLogger(AccountBean.class.getName()).log(Level.SEVERE, null, ex);
return null;
public String Logout() {
try {
servletRequest.getSession().invalidate();
return "../login";
} catch (Exception e) {
e.printStackTrace();
return "";
Best Regards,
Coy.

I looked up it but it seem not work with me. Almost example which i found is run on Glass Fish. But I am running on TomCat server of Netbeans 6.9.1. Can someone give me another suggestion ?
Thanks in advance!

Safari 7 Preferences: I can't delete a web site login and password

Hello:
I can't delete a safari web site login and password
After tapping delete all there is 1 item still in the box.
¿How can I delete it?
Thak's in advance,
Luis

I had the same problem, and the solution was to delete the entries using the Keychain Access tool, found in Applications → Utilities. You can search for the entry there, remove it, and then it will be deleted from Safari as well.
(I had to do this when I changed my email address on Amazon, and all the auto-login pages had the old email addresses and wouldn't update. I tried to delete them from Safari's passwords dialog and ran into the problem you described).
Note that this question provides the same answer in more detail.

Correlate login and logout times in a table

I have a table LOGINDATA with three columns: USERID, TYPE, and TIMESTAMP.
USERID stores a unique integer that represents someone who uses the system.
TYPE is either 1 or 2. 1 represents a login. 2 represents a logout.
TIMESTAMP is a value that comes from System.currentTimeMillis. It represents the current time in milliseconds since January 1, 1970 (I believe that's the right date).
I'm trying to create a query to link each login time with its corresponding logout time, so that my resultset has three columns:
USERID, LOGINTIME, LOGOUTTIME.
I assume this would involve joining the table to itself, but creating a query to find the closest login and logout times is tricky.
What I have now is:
select li.userid, li.logintime, lo.logouttime from
(select userid, timestamp logintime from logindata where type = 1) li,
(select userid, timestamp logouttime from logindata where type = 2) lo
where li.userid=lo.userid
and li.userid=999999 is the userid of one user.
This will actually end up being more complicated with missing logout times, but this is a start.

The data design makes this a very very very messy (and probably slow) query. Fundamentally, I consider designs like this to be broken because they're so hard to get relevant information out of the raw data; in some cases impossible (see comments below).
The following query works on Oracle database (where TIMESTAMP is a reserved word, so I used EVENTTIME instead) - I tested it with a few rows of data:
select li.userid, li.logintime, min(possible_logout) logouttime
from (select userid || to_char(eventtime, 'yyyymmddhh24miss') session_id, userid, eventtime logintime
      from logindata where type = 1) li,
   (select li.userid || to_char(logintime, 'yyyymmddhh24miss') session_id, li.userid, logintime, logouttime possible_logout
    from (select userid, eventtime logintime from logindata where type = 1) li,
         (select userid, eventtime logouttime from logindata where type = 2) lo
    where logintime < logouttime
      and li.userid = lo.userid(+) ) pl
where li.session_id = pl.session_id (+)
group by li.userid, li.logintime
order by li.logintime;Note that this will return the wrong result if for a particular user_id, you have overlapping logins, like:
time a - login session 1
time b - login session 2
time c - logout session 1 or 2
time d - logout session 2 or session 1
there is simply no way to tell which logout goes with which login and the query will report that both sessions ended at time c, which is absolutely unacceptable if this is to be a security audit trail... The only way to deal with this is to guarantee at the application layer that no user can be logged in twice.
Note also that it breaks by returning extra rows if a user somehow manages to log in twice or more at the same moment, whatever the granularity of your TIMESTAMP is... This is because of the join on the generated SESSION_ID; if you get 2 or more of them the same, you get a cartesian product (2 IDs, 4 rows; 5 IDs, 25 rows, etc...)
It would obviously be a lot cleaner if you stored some sort of unique session_id in your table. Note that the session_ids used for session tracking in J2EE web servers get recycled over time and are therefore unsuitable (by themselves) as unique session ids. And if you store a session id, then you can fix your broken data model and avoid all this mess in the first place by making your table have the columns:
USER_ID, SESSION_ID, LOGIN_TIME, LOGOUT_TIME
Insert on login, update on logout...

Report for login and logout time

Dear All,
Please can some one help me urgently.
I have to find out users login and logout time over the last six months. I need to find out how many hours per user are being used. What report do I need to run to find out ?

Hi,
Check the system log saved in your system.Normally the basis admin woulfd know better about this .Only they have the access and maintance for it.
Anyways u can try out some other ways also
Profile parameters rslg/local/file
/usr/sap/<SID>/D20/log/SLOG<SAP-instance_number> Specifies the location of the local log on the application server.
Alternatively try to table - SYST
Note: there are many transaction codes that can be accessed only by super users .do tell me if u have one so that i can give you?

Web Application Proxy and Safari

Morning, all.
I've installed and configured the new Windows Server 2012 R2 AD FS and Web Application Proxy, and I've run into some strange problems. I had some initial problems getting it to work, the documentation is a bit thin, but I now have Sharepoint and Webmail
published to the Internet.
I'm using x.509 Certificate Authentication for Extranet.
In IE on a Windows 8.1 Surface Pro everything works. I can log in using ether a softcert or a SmartCard.
On my OS X Mac I can log in using Chrome, but Safari won't work.
Same thing on my iPad running iOS 7.0.4, Safari won't work. Interestingly enough, on my 7.0.4 iPhone it DOES work. Even more interestingly, I CAN Workplace Join the iPad using the URL https://<adfs fqdn>/enrollmentserver/otaprofile but
I can't authenticate using the URL https://<adfs fqdn>/adfs/ls/IdpInitiatedSignon.aspx.
I get to select my certificate, but after that I'm getting this error message: "Safari cannot open the page because too many redirects occurred." In the Event log on the AD FS server I'm getting this:
Encountered error during federation passive request.
Additional Data
Protocol Name:
Saml
Relying Party:
http://<adfs fqdn>/adfs/services/trust
Exception details:
Microsoft.IdentityServer.Web.InvalidRequestException: MSIS7042: The same client browser session has made '6' requests in the last '0' seconds. Contact your administrator for details.
at Microsoft.IdentityServer.Web.Protocols.PassiveProtocolHandler.UpdateLoopDetectionCookie(WrappedHttpListenerContext context)
at Microsoft.IdentityServer.Web.Protocols.Saml.SamlProtocolHandler.SendSignInResponse(SamlContext context, MSISSignInResponse response)
at Microsoft.IdentityServer.Web.PassiveProtocolListener.ProcessProtocolRequest(ProtocolContext protocolContext, PassiveProtocolHandler protocolHandler)
at Microsoft.IdentityServer.Web.PassiveProtocolListener.OnGetContext(WrappedHttpListenerContext context)
Since it does work on an iPhone running the same browser, and Workplace Join does work on the iPad even if nothing else does I'm thinking there's some UserAgent voodoo going on in parts of the Web Application Proxy. It's no big deal that Safari in OS X doesn't
work, we can always run Chrome, but the iPad is a major problem and a total deal breaker if I can't fix it.
I would appreciate some good advice.

Hi,
As both IE and Chrome work, I think it’s more a client side issue.
Maybe you need to clear you browser cache and cookies.
This also worth a try:
http://stackoverflow.com/questions/2640030/adfs-v2-0-error-msis7042-the-same-client-browser-session-has-made-6-request
Please Note: Since the web site is not hosted by Microsoft, the link may change without notice. Microsoft does not guarantee the accuracy of this information.
Hope this helps.

How can I retrieve the value for the selected value?
Please advice.

I NEED TO GET LOGIN AND LOGOUT TIMING DETAILS FROM CLIENT SYSTEMS

HI,
CAN ANYONE PLEASE HELP ME ON HOW TO GET LOGIN AND LOGOUT , CLIENT EVENT DETAILS FROM CLIENT SYSTEMS ON SERVER 2008 R2.
THANKS,
KUMAR.

You may need to enable active directory Logon/Logoff Audit event.
The Audit logon events policy records all attempts to log on to the local computer, whether by using a domain account or a local account.
On Domain Controller, this policy records attempts to access the DC only.
By using these events we can track user's logon duration by mapping logon and logoff events with user's Logon ID which is unique between user's logon and logoff.
Please refer to this blog to understand the complete process to audit the successful or failed logon and logoff attempts in the network using the audit policies :

Calculating Login and Logout Times - need help

Hi everyone. I have the first part of this code and can't seem to figure out the time calculation part. What it is - create a code that asks for a user name or social security number, then the person enters up to 6 login and logout times for the day. They also have the option to enter personal time or sick time (neither of which can be over 8 hours). I have all of that complete, but I can't figure out how to get the in and out times and the leave times to calculate. I have 3 pieces of code - here they are:
Hours:
import java.util.*;
public class Hours
     //define states of Hours
     int regularhoursInt = 0;
     int regularminutesInt = 0;
     int overtimehoursInt = 0;
     int overtimeminutesInt = 0;
     //set hours worked
     public void setHours(int timein, int timeout)
          int temphoursin = timein/100;

I know it is a lot of code, but I am just starting and couldn't think of an easier way to do this.
Thank you for any help - it is greatly appreciated. You can email me with any code help - [email protected].

My 2 cents, I dunno what it'll be worth.
I think you should never convert anything until the final moment that you are at actually getting the int or float number of hours.
Why are you doing all this Gregorian and conversion gymnastics throughout your calculations?
To get the current time in milliseconds, use either
java.util.Date d = new java.util.Date();
or
long d = System.currentTimeMillis();
Use this long number for all your calculations, and only at the end convert it. To convert, you can use java.text.SimpleDateFormat, which I find very straightforward to use. I honestly think you should never convert your dates before doing any calculations, only after doing them, otherwise you'll loose precision and make errors for sure.

My 27" 2010 iMac has recently began freezing and movement on the display is molasses slow. We have 500 gigabytes available and no applications running and the problems still persist. Any advice?

My 27" 2010 iMac has recently began freezing and movement on the display is molasses slow. We have 500 gigabytes available and no applications running and the problems still persist. Any advice?

IF your system is running extremely slow with no applications running other than Finder then I'd suspect a failing HD or you have a runaway process somewhere. Open Activity Monitor (Applications - Utilities - Activity Monitor) and look to see if you have any applications taking a large %CPU, if you do that is your problem. To test the HD run Apple Hardware Test, please read:
http://support.apple.com/kb/HT1509
to learn how to run AHT on your machine, also run it in EXTENDED MODE so it does the most complete test. If no errors are found after the first pass run it another 2-3 times to be thorough.
