I am using struts with hibernate.
I have one long application form. The application form is for filling up th personal details,employment details and others. My requirement is, for personal details I have one separate form bean and for the employment details in another form bean.

How to map more than one form bean to one action? How to achieve this in struts?

You cannot map an action to more than one form. You can create a single form that has all the data you need and then populate your database objects based on this data. Forms are part of the presentation layer and they should map closely to your web pages. It sounds like you are letting your database structure influence your forms.

Brent is right: You can't have more than one form bean for a given page. However, a possible work-around would be to use "embedded objects" in your form bean. You could, for example have two properties in your form bean: personalDetails and employmentDetails, each of which is a JavaBean containing properties that describe the respective areas. Then in your JSP, use "dot notation" to identify the properties. Example:


Note: It is a security risk to have a Hibernate controlled object as either a Struts ActionForm bean or an embedded object in a form bean. The reason is that someone could cause an unauthorized update to the database by "spoofing" the page. For example, if you have an Employee bean that is embedded in an ActionForm bean and you have a page that updates something about the employee such as date of hire, a spoofer could create a copy of that page, add "salary" as one of the input fields and succeed in updating the salary in the database.

You could have both the personal details bean and the employment details bean as fields in an employee action form and then access them.
If you want to populate the name field of the personal details bean then it can be done by:

Your employee action form will have a getter and setter for the personalDetails bean similar to any other field in the action form.

I have no clue as to how hibernate and struts work together but I think the above approach should suit your requirement.

I saw only after I posted my reply that Merrill has already answered the question
