Useful reference on exactly how this tag works:
http://java.sun.com/products/jsp/syntax/1.2/syntaxref12.html
http://java.sun.com/products/jsp/syntax/1.2/syntaxref1216.html#8856
sets all the properties in the bean, that have been specified in the form.
How does it do this ? Scans the incoming parameters for values that are not null/empty. Uses reflection to see if a setter for that property exists in your javabean. eg with your email textfield, it would look for the method setEmail()
The method would be invoked if there was a parameter "email=..." in the request that did not have a value of null, OR EMPTY STRING.
In what order are the beans set methods called in this instance ?Unspecified order.
Also, if I want to save the properties in the bean into a database, how would you do this ?You would have to call a helper method you write yourself. Something like myBean.save() or myBeanDAO.save(myBean)
Finally, does calling savename.jsp as the action of the form page, not go against the model/view archecture ?Yes it does - this is a Model1 technique (just using JSP pages)
If you called servlet from the form post, how would it do the same job ?The jakarta commons BeanUtils package. http://jakarta.apache.org/commons/beanutils/
It provides helper methods for this functionality - IMO better than the <jsp:setProperty> tag.
It actually handles empty string values intelligently
BeanUtils.populate(myBean, myRequest.getParameterMap());
