Desing Question

[deepaksawdekar]

Hello,
I have a separate Data Object and Action Form bean. In my form beans have a attribute 
which corresponds to Data Object. And had written a separate setter and getter methods 
for each attribute of Data object and some addition required for working of struts. 
Like this.
e.g.

public class CompanyForm extends ActionForm{
        /*
         * CompanyInfo object
         */                                                                            
 
        private CompanyInfo companyInfo;
        
        public String String getCompanyName(){
        return companyInfo.getCompanyName();
        }

        public void setCompanyName(String str) {
        this.companyInfo.setCompanyName(str);
        }
...

Now my question are
1. Is this a good design.
2. Do my Data object also have to implement java.io.Serializable interface so that 
they can be stored in session scope.
I am asking question 2 since some times i get the error saying CompanyInfo is not 
serializable. To remove this error i have to delete work directory from tomcat 
installation and restart the tomcat server. I thaught that i am getting this error 
since because data object CompanyInfo is not implementating java.io.Serializable.

Please advice.



Thanks and Regards
Deepak.
