Hi Brandon,
As you mean, I must code new BaseBean, which extends from ValidatorActionForm more than using default BaseBean of iBatis which extends from ActionForm?
If so, thank you very much ... may be my problem is solved by you :")
again, thank you!

"Right, like Mark said, I'm following JPetStoreExample, Rick :), when you use
DAO, ur Bean must extends from Basebean of DAO pattern."
Pham, the way you are explaining this doesn't seem quite right. The inheritence of the Presentation bean goes as such:
AccountBean <- AbstractBean <- BaseBean <- ValidatorActionForm
You Dao class inheritence goes like this:
AccountSqlMapDao (implements AccountDao) <- BaseSqlMapDao <- SqlMapDaoTemplate
Notice that your Dao has nothing do with the BaseBean. The AccountBean is PURELY presentation. It is akin to the AcitonForm. What JPetstore4 does is to conceptually combine the ActionForm and Action class while abstracting you away from the servlet spec. Since all of you presentation beans ultimately extend ValidatorActionForm you are able to perform validations as normal. Please don't confuse the Dao and Presentation layers. The Presentation layer merely calls the Service Layer which in turn calls the Dao layer. The domain/model objects are the only shared elements among the various layers.

So, if I want to do Validation, I only do it on Server. So, if I want do Validation on Client, I can not but I use javascript.
so, thank you all :)

Rick, I believe that he is referring the the JPetStore download from the
iBatis site. I am also using the additional struts helper package that comes
in that demo. So no, it really doesn't have anything to do with iBatis
except that it probably came from that web site.
Pham, if you continue to follow the JPetSoreExample then can do server side
validation the way that it does by extending the validate() method of
BaseBean. Then you can set validate="true" in your struts-config.
