Sorry, I still did not explain my code very well.
I am trying to write out the properties of ThreadBean
in a "while loop" in my JSP:
<%
Collection threadRows = ( Collection
)request.getAttribute( "ThreadBeans" );
int odd = 0;
Iterator iterator = threadRows.iterator();
while( iterator.hasNext() )
{
odd = ( odd + 1 )%2;
ThreadBean threadBean = ( ThreadBean
)iterator.next();
.....
.....
<%=threadBean.getSender()%> >
<%=threadBean.getThreadReplyCount()%> >
<%=threadBean.getThreadViewCount()%>
}
%>
and the error is that cannot find threadBean in any
scope.
ThreadBeans is a collection, which is created in a
java class that extends Action. And ThreadBeans are
passed in a request scope into my JSP.
ThreadBeans, which is a collection of JavaBean(s).
Each of those JavaBean(s) is a ThreadBean with many
properties to be written out in a loop. The
ThreadBean is in a package.
In my JSP scriplet, I retrieve the collection of those
JavaBean(s) from the request scope.
Then, I enter the while loop to write out the
properties of each of those JavaBean(s).
What should I do so that my JSP knows threadBean is in
the request scope?
Thank you.
