Hello All,
Let me preface this email by saying that I only put
'EXPERTS ONLY' so you hot shot programmers would actually read this email.
If you are reading this, it worked!
I have an odd problem that I was hoping someone
could help with.
I have a servlet that all jsps in the system are
dispatched from. I create a bean in this servlet and add it to the request
object like so...
com.blah.blah.MyBean abean =
(com.blah.blah.MyBean)
Beans.instantiate(this.getClass().getClassLoader(),"com.blah.blah.MyBean");
... request.setAttribute("thename",
abean);
I have also tried this to create the
bean....
com.blah.blah.MyBean abean = new
com.blah.blah.MyBean();
and also tried to place the object in the request like so....
pageContext.setAttribute("thename", abean,
PageContext.REQUEST_SCOPE);
Anywho, I then have the following in my jsp
page...
<jsp:useBean id="thename"
scope="request" class="com.blah.blah.MyBean" />
I get a java.lang.ClassCastException from the
jsp. So, I decided to do a little error hunting in a jsp using the
following code...
<%try{
System.out.println(request.getAttribute("thename") == null);
System.out.println(request.getAttribute("thename") instanceof
com.blah.blah.MyBean);
System.out.println(request.getAttribute("thename").getClass().getName()); System.out.println(zedak.docworx.jspsupport.beans.BrandBean)request.getAttribute("thename")); }catch (ClassCastException
e){
System.out.println("CLASS CAST EXCEPTION!"); } %> The results of the code is as follows:
false
false
com.blah.blah.MyBean
CLASS CAST
EXCEPTION!
So, the attribute is present in the request object,
it is not an instance of 'com.blah.blah.MyBean'; but the object's class name is
'com.blah.blah.MyBean'. Does anyone have an idea what is going on?
How can the object's class name be 'com.blah.blah.MyBean' but not be able
to cast to 'com.blah.blah.MyBean'?
Thanks in advance!
