what's the attribute name for a FormBean?

[Weining Qi <we...@info.nl>]

Hi, all,

If I want to use <bean:define> to retrieve one property of current form bean as
a JSP bean(an attribute accessible to the remainder of the current page), how
can specify the attribute name of the form bean? I have tried the name from
struts-config.xml where I define the form bean, it is still saying: "No bean
found for attribute key xxx"(the name appearing in the xml file). How do all the
html form tags know the form bean where they find "their properties"?

Finally I have to use <jsp.useBean> to introduce the form bean before the
defining.

Thanks in advance!

The form bean is created by the html:form tag, or by an Action class,
under the attribute name given in the config file. Are you looking for
it before it is created?

But, given that the flow has passed the html:form tag, or returned from
the action, and given something like 

<form-bean name="logonForm" type="org.wxxi.gavel.action.LogonForm"/>

then

<bean:define id="username" name="logonForm" property="username"/>

should expose the property logonForm.getUsername() as a scripting
variable for the page.
