Hi Emmanuel,
<jsp:useBean id="person" scope="session"
class="org.apache.taglibs.standard.examples.beans.Person" />
> <jsp:setProperty name="person" property="*" />
What are you trying to do with these lines?
Are you aware that what you're doing on the first line is creating a new
Person bean that has a session scope if there's no bean with "person" as its
id?
And you are setting all of the properties of that Person bean with nothing
on the second line?
I assume this is not what you wanted to do instead you want to access the
Person bean you set in servletContext which I think is called the
application scope. If you want to access that you could have used
${applicationScope.person.name.firstName} and
${applicationScope.person.name.lastName} where applicationScope sets the
server to look in application scope only instead of going thru the other
scopes first.
<table border="1">
<c:forEach var="person" items="${persons}">
<tr>
<td><c:out value="${person.name.firstName}"/> </td>
> <td><c:out value="${person.name.lastName}"/> </td>
> </tr>
> </c:forEach>
</table>
Where did you set the collection "persons"? Remember that when you use EL in
JSP it does not print null but instead an empty String if it encounters a
null value.
Regards,
Bob
