Error handling with taglibs

[Mike Prader]

Hi all   My problem is, that I want to mark a textfield red and set the focus to it after I checked the fields in my from the Action Class derived class and I detected an error in this input. I want to use taglibs also.   Is there any possibility to do this in my from the ActionForm Class derived class, so that Struts will automatically set this field to another colour and set the focus to it ? If not what is the best solution to mark the attribute in my from the ActionForm Class derived Class that this field isn't ok ?   regards   mike
