Shirish By dynamically generating a form i mean querying a db table which contains information about what fields etc to produce for the user to be able to add content to their site. I'm porting an existing cms written in perl on mysql, to java and oracle. I have 2 forms: 1. Admin form that basically adds fields to an sql table (AddCustomFieldAction). E.g. What kind of field would you like, etc? 2. The content manager then uses a form that is generated by the table refered to in form 1. There appears no elegant means of using struts for form 2, as the action form cant know what to expect. The only thing i can think of is posting an array of custom field values as an array and dealing with it when i get to the action or associated logic. Please tell me if i'm wrong in this, and i'm missing something. I hate not to use something because of something I've not understood.
