ADFBC attribute error and JSP bindings

Question

In the following code based on that in Oracle ADFToystore example the ${curBinding.name}
expression seems to be returning the name of the binding itself and not the name of the
DataControl attribute on which a JboAttrValException is thrown.
<c:forEach var="curBinding" items="${bindings.ctrlBindingList}">
<% JUControlBinding cb =
(JUControlBinding)pageContext.getAttribute("curBinding");
if (cb instanceof JUCtrlValueBinding &&
!(cb instanceof JUCtrlRangeBinding) &&
!(cb instanceof JUCtrlHierNodeBinding)) { %>
<c:set var="name" value="${curBinding.name}"/>
<html:errors property='<%= ((String)pageContext.getAttribute("name")) %>'/>
<% } %>
</c:forEach>
If my UIModel has a binding name which differs from the attribute name I do no see an error
thrown as JboAttrValException.
e.g.
<DCControl
id="Sfn"
SubType="DCTextField"
IterBinding="PayeeDataInstIterator"
ApplyValidation="false"
isDynamic="false" >
<AttrNames>
<Item Value="PayeeSfn" />
</AttrNames>
</DCControl>
curBinding.name debugs as 'Sfn'
exception thrown against 'PayeeSfn'
I can see the attribute exceptions in the JSP page if I change the code as follows;
<c:forEach var="curBinding" items="${bindings.ctrlBindingList}">
<% JUControlBinding cb =
(JUControlBinding)pageContext.getAttribute("curBinding");
if (cb instanceof JUCtrlValueBinding &&
!(cb instanceof JUCtrlRangeBinding) &&
!(cb instanceof JUCtrlHierNodeBinding)) { %>
<c:forEach var="curBindingAttrName" items="${curBinding.attributeNames}">
<html:errors property='<%= ((String)pageContext.getAttribute("curBindingAttrName")) %>'/>
</c:forEach>
<% } %>
</c:forEach>
Is this correct/safe, Is there something back when the Jbo Attribute level errors are added
as struts actionErrors that should be done ?
Anyone have any ideas on the best solution to this problem ?

An example of the useBean that does not work would be nice. Of a first guess is that your class does not appear to be in a package. As of java 1.4.2, you can not import (and therefore use) classes from the default package into a class that has a package. And your server's JSP class is in a package, therefore, it can not access your bean that is in the default package.
Put your bean in a package and try again:
//Your UserData1.java first line of code:
package my.jsp.beans;Compile, and make sure the .class file goes to:
[Application Context]/WEB-INF/class/my/jsp/beans/UserData1.class
Then your useBean will look like:
<jsp:useBean id="userData" class="my.jsp.beans.UserData1" scope="page"/>
