validating selection list in struts!

[rameshraj]

Hello all,how can i validate the selection list in struts using validation.xml file.

I have the list populated in the following manner:
{code}<html:select property=...>
<html:option value="">Select your gender</html:option>
<html:options collection property=.....>
</html:select>{code}

If the user submits the page without selecting any options the default:"Select your gender" without any value will be posted and the validation should validate this and generate some error message on the same page.

Hi, U can validate property <html:select property=...>

check length or not null for this property.

Actually I wanted the jsp page where the selection list is printed as the input page in the struts-config.xml file.I think u understand. I need to validate using the struts validate=true property from the struts-config.xml file and not directly comparing the value what was posted after selecting and submitting the page.
I have already implemented the logic u said. Any way thank u very much for your kind response.
