ActionForm subclasses have to implement Serializable?

Hello everyone,
In Jakarta struts API ActionForm, there is a sentence -- "Because ActionForms are JavaBeans, subclasses should also implement Serializable, as required by the JavaBean specification."
If I create my own super Form like this:
public abstract class MyGeneralActionForm extends ActionForm { ... }
it will still work. My question is -- do we have to implement Serializable?
Thanks a lot!

How to use Reset in Struts JSP?

Hello everyone,
If I use a form bean and <html:text property="someName" />, then Struts will put whatever the form bean's "someName" is into <html type="text" value="blah">, where blah is the value of form bean variable "someName". A Reset button won't be able to clear up the default value attribute. How can we write the JSP custom tag to have Reset clear?
Thanks in advance.

Java in General

business logic (in java or PL/SQL)?

Just what I've seen.
1. In security perspective, if you use PL/SQL, then your business logic won't be transferred over your network.
2. On the other hand, from J2EE structure point of view, each Java bean should match one table and we implement all the functionalities associated with that table inside this Java Bean. If you want to use PL/SQL, you are more flexible in reducing Java bean usage.
In the real industry, both are popular.
