Instantiating a bean in the web layer

[pranxas]

Hi

I'm making an application where I need to have a bean, containing all the user information, which can be accessed in the DB layer(DAO's). The problem is that I don't know how to create and instantiate it, since it will only be build after the user logs on.
I'll try to explain better showing the code:

-The class which I want to make a bean:


public class User_Permissions {

private User user;
private LinkedList<GroupPermOperations> listGpo;
// ...Getters and setters

}


-The controller where I want to create the bean:

public class LoginFormController extends SimpleFormController{

private UserManager userMan;
protected final Log logger = LogFactory.getLog(getClass());

public ModelAndView onSubmit(HttpServletRequest request, HttpServletResponse response,Object command, BindException errors) throws Exception{
String username=((PasswordGetter) command).getUser();
logger.info(((PasswordGetter)command).getUser());
String inputPass=((PasswordGetter) command).getPassword();
String realPass=userMan.getPassword(username);

if(realPass==null){
logger.info("user rejected");
errors.rejectValue("password","error.wrongPassword",null,"Wrong Password");
return new ModelAndView(this.getFormView(), errors.getModel());
}

else if(inputPass.equals(realPass)){
User person=userMan.getInfoList(username);
int user_id=userMan.getUserId(username);

User_Permissions up=userMan.getUserPermissions(user_id);
up.setUser(person);
//HERE IS WHERE I WANT TO MAKE THE BEAN FROM 'up'

WebUtils.setSessionAttribute(request, "activeUser", up);
ModelAndView nModel= new ModelAndView(new RedirectView(getSuccessView()));
return nModel;
}
else{
logger.info("password rejected");
errors.rejectValue("password","error.wrongPassword",null,"Wrong Password");
return new ModelAndView(this.getFormView(), errors.getModel());
}
}
}


How can I also define this bean in the servlet.xml?
Can anybody help me on this?

Thanks is advance

First of all, your bean seems an "entity" which means that you should not configure it in your servlet.xml.
Better if you configure a "UserPermissionService" with a method like "loadUserPermissions(User user)" and inject it in your controller
