Petclinic enhancement - ClassNotFoundException

[Girish Varde]

Hello Friends,

I have already deployed Petclinic example in Tomcat 4.1

I then extended it and started displaying my own form. I added to HibernateClinic.java my business which is called from onSubmit of Form class newly added).

But the Ant warfile is not generating new jar file of my application and I get above excpetion on request.

Why is the original class on modification not getting copiled?
The jar file of my apps is very small contained in war file (ant generated)

Pls help.
