Hi,

I have some textfields in my html page & i want to validate that fields for blank values or for wrong values using custom tags built by me in jSP.

So please tell me how it would be possible??

Thanks,
Jignesh

Are you sure you want (can?) to do this with custom tags ?
This sounds like more Javascript or server side stuff.

I think that tags will act at response time,
but you want to check the validity of the field at request time.

Tags are used mostly for writing or modifying outgoing text.
Server side validation is generally done in a servlet or bean.

You have a misunderstanding of the fundamentals of how jSPs work. Perhaps this article might help.
