Help with DynaActionForm

["Kalluru Uma. Maheswar" <Ka...@adeasolutions.com>]

Hi,

I posted the same question last week but could not get any reply. Can
someone help me please?

 

How do I validate if a field is entered or not using the DynaActionForm?

 

My HTML form has <html:text/> and <html:radio/> buttons. I want to check
if the user has entered some text in the text field and that he has
selected the radio button.

 

If he has not selected, then show him a error message in the jsp. How to
do this? Do I need to configure any xml file for this? An example would
be great.

 

Thanks

Uma

don't use DynaActionForm. use DynaValidatorForm. if you specify the rules on
validation.xml it will get fired automatically. it will automatically
generate the javascript and even if the user has disabled javascript, before
the action is executed, the RequestProcessor runs the validation on the
server side and if something goes it forwards to the action input.


try a simple form at first... with only one rule and see what happens.

check the files on attachment ;).

But since I am not writing any validate() method, how do my validate() get
fired? And if I have to show error messages to the user, how do I handle
this?

Sorry if my questions are stupid, I am new to struts.

  check commons-validator.

  declare the commons-validator plugin on your struts-config.xml.
  use the validator-rules to specify validation rules (basic copy paste).
  use the validation.xml to specify the rules that apply to which fields on
a form.

  on your jsp use <html:javascript/>.

  check commons-validator.

  declare the commons-validator plugin on your struts-config.xml.
  use the validator-rules to specify validation rules (basic copy paste).
  use the validation.xml to specify the rules that apply to which fields on
a form.

  on your jsp use <html:javascript/>.
