Simple Database Application with JSF (User Login)
January 21, 2010 70 Comments
Here I am not going to show you step wise operation but I am only providing you the source code for each file that I have implemented for a Login application based on database. I hope you can easily follow these instructions after going through first three tutorials that I had published in previous post .
Here in this example we are having a login page. On Login button click, the username and password will get checked for login, if succeed then directed to success page otherwise ask to retry. And yes, I have used JDBC connectivity for MYSQL database. and I have used Netbeans IDE for this application.
Here we have files:
Inside Web Pages directory
login.jsp -for login interface
login_fail.jsp -for re-login interface
success.jsp -page after successful login
Inside WEB-INF directory
faces-config.xml – JSF configuration file
Inside beans package
login_bean.java – here we define the connectivity and logic of the program.
Inside messages package
message.property -It holds the message for validation.
Inside CSS directory
style.css -CSS styles for the given JSP pages.
Database -db_jsf
Table – tbl_users
Fields -ID, UName, PWord
login.jsp

Hi Prachant,
This is a good example of how to connect to mysql using managed beans and JSF.
Now It would be better to show us, for this same example how to use JSF + Spring and hibernate with detailing also the directory hierarchy (where to put the xml, java and jsp files).
Thank you,
Lyes.
Hello Lyes, you are very much welcome… and sorry to say you that, I am just learning JSF. I post what i had practiced. So no much idea about Spring and hibernate. Thank you for your comment..
Tthank you Prachant.
send me your email address i want to ask u something asarraf8@gmail.com
hi can u explain me how to create a login form for multiple users…………
if you can communicate from database, i think you can easily make multiplier login.
Hello lurdhu
Your login form will be for multiple users if it is connected to databases.
First register multiple users with registration form and provide them username and password and store all information into your database and during login check username and password with database.
It will work for multiple users.
If i didn’t understand your question,then plz let me know and explain your question in detail.
may be add the textbox in runtime
like when u click + sign add text boxes
for new user
thank u i got it.but now new problem is that ,when i try to insert values to database via form using jsf..it showing me null pointer exception ….
can u tel me the possible solution for it plz…
thanks in advance
hello lurdhu,
can u tell me the exact location , where the error is coming and paste the error code.
Hi i followed your example but i used a connection to a sql db, after i enter the login and password i get this error
“javax.el.MethodNotFoundException: Method not found: beans.login_bean@5b6b1943.checkValidUser()”
Can you help me?
Thanks
It seems you have not defined checkValidUser() in login_bean class
or you may be using older version of J2EE, please try with J2EE 5 or 6.
I like the example, it helped a lot!
uhmm, how could i do this if the log-in part is a dialog in jquery? if i use actionerrors, the page would redirect somewhere…
Better you create a relogin page, so that if the dialog get error, it will redirect to the relogin page.
Previously, even twitter had same concept.
using this concept into struts may be quite tough(even i may need to check).
but you can use pure struts to achieve like this. Example you can find here
hi!
i want to change this method !
38 public void dbData(String UName)
39 {
40 try
41 {
42 Class.forName(“com.mysql.jdbc.Driver”);
43 con = DriverManager.getConnection(“jdbc:mysql://localhost:3306/db_jsf”,”root”,”root”);
44 ps = con.createStatement();
45 SQL_Str=”Select * from tbl_users where UName like (‘” + UName +”‘)”;
46 rs=ps.executeQuery(SQL_Str);
47 rs.next();
48 dbusername=rs.getString(2).toString();
49 dbpassword=rs.getString(3).toString();
50 }
51 catch(Exception ex)
52 {
53 ex.printStackTrace();
54 System.out.println(“Exception Occur :” + ex);
55 }

Hello Jah, please once check with all the notation that you have used.
I am facening same problem is there any special lib required from notation?
I?ve learn several excellent stuff here. Definitely price bookmarking for revisiting. I wonder how a lot effort you set to make this kind of wonderful informative site.
I have been surfing on-line more than three hours nowadays, yet I by no means discovered any interesting article like yours. It?s pretty price sufficient for me. Personally, if all site owners and bloggers made excellent content material as you did, the internet can be much more helpful than ever before.
Hello there, I discovered your web site via Google whilst searching for a similar topic, your website got here up, it looks good. I’ve bookmarked it in my google bookmarks.
I check this code with jsf 1.2.it runs sucesfully but does not display any message.it stucks on login.jsp page only rather than go toward login_fail.jsp page or success.jsp page.Please assist me soon
Hi Bheem,
Once please check your “faces-config.xml”.
please assist me where to keep CSS file and how to edit message .property manually.
And session by it aplicattion
Generally I do not learn post on blogs, however I would like to say that this write-up very pressured me to take a look at and do so! Your writing style has been surprised me. Thank you, quite nice post.
can u please provide the xml file for this

can u tell me why my login page is not being displayed??
I found this post to be extremely helpful also and for that I thank you. One issue I have is at login success. On your success.jsp page:
Hello , you are successfully login.
My page is a little different in that I require the login (email address) on the login.jsp page, and on success, I want to display the user’s actual name from the database. I am retrieving this successfully as shown in my logs, but cannot get it to display on the success page (mine is called homepage.jsp). It just displays Welcome .
My code for the homepage.jsp page:
Welcome .
Note that I am pulling values from another managed bean on this page also which are bound to actions (buttons) on the page. That should not be a problem though. I don’t know why the “username” property does not show up on the page when rendered. Any ideas with this?
Hi Prashanth,
Wats the url. im not able to see the login page on server publishing. Kindly assist me. Thanks.
thanks prashant for giving this example,but i have some doubt in line no.26 in login.jsp,plz explain.
sorry ,it was line no.27 in login.jsp
Hello anju,
It is just to display the error msg for the given field(password) with some css style.
Thanks for this post. I finally got a managed bean in Netbeans to connect to the sakila DB in MySQL. I have been following the Deitel How to Program 9th ed and they only have an example on how to connect to the JavaDB database.
It is an useful post for JSF learner ….Like me ..We expect this kind of Samples to learn more things…thanks yar..

Great blog! Is your theme custom made or did you
download it from somewhere? A design like yours with a few simple tweeks would really make my blog stand out.
Please let me know where you got your theme.

Hi very useful post thanks a lot but where can I find your database schema?
hello, i enter the login and password i get this error “Impossible de trouver un cas de navigation correspondant depuis l’ID de vue «/login.xhtml» pour l’action «#{login_bean.checkValidUser()}» avec le résultat «invalid».”
Can you help me?
This is the right website for anyone who wishes to understand this topic. You know a whole lot its almost hard to argue with you (not that I really will need to…HaHa). You certainly put a brand new spin on a subject which has been written about for a long time. Great stuff, just wonderful!
