Unnable to make validations work for login screen

**fierof2** · July 27th, 2010, 03:24 AM

Hi All

I am breaking my head for a long time. Everything seems to be fine but I am not able to apply validation framework to my login screen. Everything seems to be fine but still validation is not working. Currently what i am trying to achieve, is to throw error message when the user doesnt enter the username in the login screen.

The attached zip file contains the entire code i have developed but cant figure out what mistake i have made. Even though i don't enter the user name in the login screen the action gets executed and error message is not displayed. It would be really great if someone could identify what mistake i have made in the code.

Its a hugh bunch of code for anyone to search thru. Can you reduce your problem to a small program that would compile and execute and demo the problem? Remove all the code that is not part of the problem.
Have you tried debugging it by adding println() statements to show how variables change and where execution flow goes?

Hi Norm

I have attached the new zip file that contains only the login page info. All the unwanted files are removed from this.

Sorry, I don't have a server with jsp etc.

**fierof2** · July 28th, 2010, 07:07 AM

what do you mean. Do you mean to say the attachment doesnt contain jsp ?

**Norm** · July 28th, 2010, 07:37 AM

Sorry, I'm not able to make any use of your zip file. It's way to big and complicated and requires many resources that I don't have.
I was looking for a single file (less than 800 lines) with one or more classes that would compile and execute and demo the problem.

You need to use some debug techniques to trace thru the logic and find out what is wrong.

**fierof2** · July 29th, 2010, 02:15 AM

Hi Norm

I thank you very much for your sincere efforts put so far to help me.

The newly attached zip file contains only 3 simple java files

The zip file has only 3 java files

LoginAction
LoginForm
Contants.java

and only 2 jsp files

login.jsp
error.jsp file

struts files are also present

others files are js,css, and images which you dont have to worry about.

I think if you take a look the below files

1.login.jsp
2.LoginForm.java
3.LoginAction.java
4.struts-config.xml
5.validation.xml

You should be able to identify the issue by looking the above files alone.

If you need any other assistance please dont hesitate to contact me, i will definitely help you in that.

**Norm** · July 29th, 2010, 07:12 AM

Sorry, I don't have the environment to test any code other than what is in .java file that can be compiled and executed.
Nothing for .jsp files or struts.
