in your struts-config.xml you can define a form-bean that has 1 property, say 'myFormBean' of type 'com.my.db.DTOBean'. you can pass the entire data object into the form property inside your action. in your jsp, you can refer to your object's properties using the reference 'myFormBean.lastName' etc. this expression language reference can be used inside the actions and validation.xml definitions as well.
