A coworker claims this is a bug in reflection when used to introspect any class called "Component" - it always thinks it's java.awt.Component. YMMV.

Will it is in his classpath indirectly it is not in his jsp unless he did a
import of it.
So it looks like this is another issue.
Unless there is a component besides java.awt.Component that I don't know of.

java.awt.Component is also in your classpath maybe c:out is trying to cast your object as that instead of x.y.z.Component?

Hi,
I am not sure if this is a struts, taglib, or jstl issue but I will
start here. I am using Struts/JSP's and am running into an error when I
try and reference my own object called Component.class with <c:out>
tag. I first load my test objects into the session in the jsp page like
this:
<% x.y.z.Component component = new x.y.z.Component();
x.y.z.Xomponent xomponent = new x.y.z.Xomponent();
session.setAttribute("comp2",component); session.setAttribute("xomp2",xomponent);
%>
Next I try and view the value of the name like this:
<c:out value="${comp2.name}"/>
Here is the error I am getting:
org.apache.jasper.JasperException: An error occurred while evaluating custom action attribute "value" with value "${comp2.name}": An error occurred while getting property "name" from an instance of class x.y.z.Component (java.lang.IllegalArgumentException: object is not an instance of declaring class)
I have played around with this a bit and set up a small test environment. Here is my application list:
Tomcat 4.1.18 Struts 1.1 rc1 Java 1.3.1_06-b01
I have found that I can use the Runtime JSTL core tag like this and it works fine:
<crt:out value="<%=((Component)session.getAttribute("comp2")).getName()%>"/>
I can also use the <jsp:useBean> tag like this and it works fine: <jsp:getProperty name="comp1" property="name"/>
I have also found that if I take the exact same class and simply rename
it to Xomponent instead of Component and keep it in the same x.y.z
package, it works. So I can then do:
<c:out value="${xomp2.name}"/>
Any ideas on this? I have my very small test beans and jsp page if someone needs them.
Thanks, John -- ******************************** ** John Thorhauer ** Web Developer ** Phoenix Color Corp. ** [EMAIL PROTECTED] ********************************
