(Login Application) in MVC2.0
Hi All,
I want to make a simple and small application (Login Application) in MVC2.0.
Can anyone give me the code and or example as I have no idea how to program in MVC2.0.
As far as my knowledge concern we will make three files for making Login application in MVC2.0:
1) CustomerLogin.jsp (View)
2) LoginServlet.java (Servlet as a controller)
where we have only methods that is to be used for validation.
If I am not wrong that is validator and deligator but am not much clear about these two terms - Validator and Deligator.........
3) LoginBean.java (Bean as a business logic)
where we will create sql statement and fetch the data from database and other logic..
Is there any other file that is to be created ?
If anyone has some idea and or can send me the code....
Please reply soon.
Thanks

How do you use a custom login application?
I have setup a custom Login Application as instructed from the admin guide, but cannot find any instructions on how you then go about using it. Some other posts on here mention customising/linking a page to it based on the user Login.jsp, but they arn't clear on the steps to do this.
The solution I was using was a single sign on system called CAS, which handled the authentication. The class I used is shown here:
http://www.ja-sig.org/wiki/display/CAS/CASifying+Sun+Identity+Manager
The java class is called: CASResourceAdapter.java
Most of this code is not used. The bit you would be interested in is in the method named:
public WavesetResult authenticate(HashMap loginInfo) throws WavesetExceptionIf you delete all the code in here and replace it with the code below as most of this is a customised search that the author wrote:
final String method = "authenticate";
if (_trace.level1(this,method))
_trace.entry(WSTrace.LEVEL1, this, method);
WavesetResult result = new WavesetResult();
String userId = (String)loginInfo.get(USER);
if(_trace.level2(this,method))
_trace.info(_trace.LEVEL2, this, method, USER + " = " + userId);
_trace.info(_trace.LEVEL2, this, method, "map: " + loginInfo);
if (_trace.level2(this,method))
_trace.info(_trace.LEVEL2, this, method, "Obtained user '" + userId + "' from info: " + String.valueOf(loginInfo));
result.addResult(Constants.AUTHENTICATED_IDENTITY, userId);
return result;You could also remove the trace code. The code you would be interested in particular would be:
WavesetResult result = new WavesetResult();
String userId = (String)loginInfo.get(USER);
if(_trace.level2(this,method))
result.addResult(Constants.AUTHENTICATED_IDENTITY, userId);
return result;The logininfo is a method used to retrieve whatever userid was used to authenticate. This is what was needed to retreive the userid from CAS. You will need to replace this with custom code to retreive the userid from your webservice.
Once you are happy with the code, place the compiled class with the correct package levels in idm/web-inf/classes. You may need to create the folder called classes.
Next login to your idm and goto resources and then configure types. Add a custom resource to point to your new class In my case it was edu.unmerced.idm.adapter.CASResourceAdaptor. Save this and then add this as a resource in your resources screen and except all defaults and give it a custom name of your choice.
You then need to add this resource to each of your users.
Next you need to goto configure and then login. In here you need to create a new login module group and point it to your CAS resource. Then change the default login for the users login application to use this new login group. See idm specific documentation on how to do this
Reboot your idm application server.
You would now use your alternative webservice system to authenticate and then afterwards get it to forward to your idm and if the code picks up the user from your webservice correctly you should be logged into idm as that user. -
Username availability in post-login application processes
Hi there,
I have a problem with a post-login application procedure that sets session variables. Some of the variables are based on the username of the user that is logging in. I'm using the function htmldb_custom_auth.get_username to return the username. However, it always reports 'nobody' as the username.
Is there a way to get the username of the logged-in user in a post-login application procedure?
RobertBy "post-login application procedure," I mean an application process whose "Process Point" property is set to "On New Session: After Authentication".That firing point means once per session at the point during the rendering of the requested page after the step where the user identity (if any) has been determined. If the first page requested is a public page (which might be the login page specified by your authentication scheme) then the user identity has not yet been established and will be null, 'nobody', 'APEX_PUBLIC_USER', 'ANONYMOUS', or perhaps some other public user name, depending on "how your application works".
You should put code like I think you have in this process into the authentication scheme's Post-Authentication Process. This block will be executed after the login API has processed the login request and after a session has been created and registered with the authenticated username.
I'm not sure what you're asking about how my application works.I was looking for a technical description of what you intend to happen in the scenario, e.g., User starts browser -> user requests URL like f?p=100:1, -> user sees login page which is page number 101 in application 100 and is specified as the Session Not Valid Page in the application's authentication scheme -> user enters username and password and presses Login button -> On New Session process should fire after login page is submitted and capture authentication username -> etc.

How to work with EJBs and database for a simple login application
Hi all :)
I am new in JSP,EJB and Servlets. I just wanted to develop a simple login application, using JSP+EJBand servlets. In some tutorial I found that the beans are already populatesd with database records. But will it be good logic to retrive all records into a bean and then search for a perticuler users data for authentication.
Can any one tell me me what is the best logic for doing so. :(
Thanx in advance.Himanshu.Shekhar wrote:

After 10.4.8 Upgrade: "Login Application crashed"
I upgraded to 10.4.8, but since the upgrade installed I am not able to boot:
I get past the grey screen/spinning wheel successfully to the Login Window with the status bar; then I get a blue screen and in 1s intervals the spinning wheel comes up and disappears.
I started in verbose-mode and the last messages I see is that the Login Window Application" starts and then crashes, a log is written for this app (which I can't access, since I can't logon). Then the Login app tries to start again and crashes again and so forth - I have to shut down the laptop or it keeps going that way.
Its possible that the 10.4.8 upgrade installed (maybe) incompletely; I had to leave the installation process, when I came back the machine was shut down. It actually showed first a blinking white led upon startup, not even the grey screen (which is according the support pages a memory problem indication). I pulled out the memory and put it back in, reset PR, then I got at least to the status described here; I started from the OSX disk and repaired disk - no repairs required and no help either.
Any ideas?
Txs,

ok..this is the situation...
all applications are routed through a login page...
so if we have a url like www.abc.com/appA/login?param1=A¶m2=B , the query string must be passed onto a servlet(which is invoked before the login page is displayed)..the servlet must process the query string and then should pass all those values(as hidden values) to the login jsp..then user enters username and pswd, then there should be another servlet which takes all the hidden values of jsp and also username and pswd, authenticates the user and sends the control back to that particular application along with the hidden values...
so i need help on how to parse the query string from the original url in the servlet, pass it out to jsp, and then pass it back to the servlet and back to the original application...damnn...any help would be greatly appreciated...thanksWell, you wouldn't do that with Java Programming much (this is the Java Programming forum and not the Servlets forum).
Best way is to use a Filter. If the user isn't logged in, then stash the parameters in the user's session and forward to the login page. After a successful login, forward to the actual requested page with those parameters. -
Not able to login - application express 4
I have downloaded oracle express 10g, and application express 4
configured on Scenario 2: Downloading from OTN and Configuring the Embedded PL/SQL Gateway
followed the installation procedures religiously
now i am not able to login thru admin
can anyone suggest what could be the issuebut in solman there is Microsoft SQL SERVER 2005 is installed and i m not able to connect to database for delete sap*
So no user/password, no access to the DB... then you simply cant logon.
You need to at lease be able to use a sql session to delete the sap* user at DB level to be able to logon. Changing the paremeter login/no_automatic_user_sapstar when SAP* exist in that client does not work.

I have an iMac G5 w/ iSight camera (Mac OS X 10.5.8). I was wondering if it were possible to do any or all of the following:
Start an app only when the computer is booted instead of every time I log in
Start an app when I log in at a specific time chunk (Such as between 5:00 to 5:30 PM, when I get home from school)
Run an app when the computer is about to go to sleep by itself or when I put it to sleep (two different apps)
I made a couple of Automator applications that will make the computer speak specified text (Adding a "Get Specified Text..." script and adding a "Speak Text" script with Alex's voice). I would really appreciate any input about this situation.
Thanks!1. I suspect you could 'fudge' this…
Applications can be made to run on login. If you check that the Mac has just been booted (say in the last 5 minutes) you can decide to run the app or not.
Some system apps can run before you login but it is very tough to setup & troubleshoot, just stick with login items if you want the app to have access to the GUI.
For example (this is a Terminal command)…
uptime | cut -d' ' -f4 -f5
…will show the time since last reboot…
1 days, or 5 mins, etc
An Applescript could use that info via something like …
set lastrebooted to do shell script "uptime | cut -d' ' -f4 -f5"
Personally I'd get the figure & the word separately
set lastrebootedfigure to do shell script "uptime | cut -d' ' -f4"
set lastrebootedword to do shell script "uptime | cut -d' ' -f5"
Then you can compare if figure is less than 5 & the work is 'mins,'
2. Check iCal it has the option to open Applescripts as 'alarms'. I can't remember what versions supported it so dig into the settings within an event. It should be able to launch an application from that.
3. I'm not aware of any system notification that you could use to handle 'do stuff before sleep'. -
I deleted my login application...
I accidentally deleted my log on application, then I restarted my computer. Now when I try to log on, it will not let me. Does anyone know if and how I can fix this problem??
Try reinstalling the OS. You shouldn't loose data, and it will replace the missing OS components that are required.

ADS application login time takes 2 minutes
Hi we have deployed 6 applications in one of our managed server and among the 6 applications is the ADS login application which connects to other application modules after loggin in.
We are using wls-10.3.3. We have given 2GB heap space to that managed server. We are using these applications in our Test environment.
When ever any single user trying to login in to the ADS login application in windows, it takes about 2 minutes to login and then home page of the application is displayed.
Please any one give suggestions on how to decrease the login time.Hi Rene,
After giving the userid and password in ads login application and click login we see the browser connecting to the application and we get the message "http://pstest/psadslogin/faces/login/ldappsverify.jspx-Windows Internet Explorer" on the top of the white page and it is displayed for long time, where ps(project sundaram) is the name of our project. It is taking time in authentication and in verifying the ldap directory. The home page of the application is displayed after 2 minutes, some times 1 min,sometimes 30sec, sometimes less than 30 sec and in rare times it displays fast in 5 to 10 seconds. I am not understanding why it is taking long time to login. Suggest any parameters to be set in Weblogic server side.
Please suggest any ideas on this. We have deployed the applications in Oracle weblogic server 10.3.3, in linux server. And we are using Oracle 11gR2 database.
Thank you.

Bad URL in BSP applications for login
I have some BSP applications using the following URL for login (standard SAP login page):
/sap/public/bsp/sap/system/login.htm?sap-url=<%=PATHTRANS%>&bspchangepasswordvisible=X&bspclient=001&bspdontshowhttpswarning=X
this URL for login works good with a WAS 6.20 but not with a WAS 6.40
Does anybody have an idea of why ? or if there is another login page to call in the WAS 6.40 to have the same functionality ?Hi Eric,
in fact, there is a new login application available in 6.40, a lot easier to integrate and with more features than the old system application.
To activate do the following: in SICF - at the tabrider where you configure the redirect to ../system/login.htm - you can find a checkbox labeled 'System Logon'. Setting this checkbox enables the new logon. The button 'Settings' opens another window where you can configure fields, default values, styles etc.
Documentation is at http://help.sap.com/saphelp_nw04/helpdata/en/ff/c7de3fc6c6ec06e10000000a1550b0/frameset.htm.
There is a set of weblogs in work to cover customization. In case you have further questions open a thread in this forum with topic '6.40 System Logon'.
What is the error or problem which you get using the redirect to .../system/login.htm in 6.40?
regards, Ulli
