In JSP 0.92, a method named processRequest() was always called on a bean
when it was created, but this is no longer the case in JSP 1.0 and 1.1.
If you want something to happen only when the bean is created, you can put
it in the body of the useBean element:
<jsp:useBean id="registerbean" scope="session" class="AMCreg.register">
<% registerbean.processRequest(request); %>
</jsp:useBean>
In JSP 1.1, you may want to change the bean into a custom action instead,
see the Tag Extension Framework section of the JSP 1.1 spec
