In my application I am using a single form bean for all the forms.Now,to validate a particular form field I have written individual validate() methods in the action classes .but the problem that I am facing is that I dont see any error message in the jsp pages when a validation error occurs.
Here is one of my validation methods:

and here is my jsp page

The validate method is supposed to be inside the ActionForm class that you create.
Here is one of my validation methods:


That is not the correct implementation of validation method. It should be something like this


Please try and let us know.

Yes,I know that but the problem is that I have a single form bean for the entire application.So,if I write a validate method in the ActionForm class I would be validating all the form fields (i.e all the fields in all the forms of the entire application) each time I navigate to a particular page containing a particular form.

In that case, i would suggest to handle the validation inside the Action class itself. I would suggest you to use the validation framework built into struts.

I am handling the validations in the action class itself..I have just created a separate method named validate() in each action class

This is how I call the validate() method.And if validation error exsist then the control returns back to the page where I redirect using findForward().But the problem is that I can't see the error messages.

Ok, sorry to mis-interpret your question.

Is "common.file.err" present in your properties file?

In the validate method, you are adding errors, but not saving it.
Please save all the errors.

This might be of help
