Class cast exception ...
I get the following error in tomcat:
java.lang.ClassCastException
at
org.apache.jsp.EditOffering_jsp._jspService(EditOffering_jsp.java:129)
I looked at EditOffering_jsp.java and it has this at line 129:
locationHelper =
(com.wavesinmotion.cw.classes.jsphelpers.LocationHelper)
pageContext.getAttribute("locationHelper", PageContext.SESSION_SCOPE);
which in the corresponding .jsp page is:
<jsp:useBean id="locationHelper"
class="com.wavesinmotion.cw.classes.jsphelpers.LocationHelper"
scope="session">
<jsp:setProperty name="locationHelper"
property="dbReader"
value="<%= session.getAttribute("DBREADER")%>" />
<jsp:setProperty name="userHelper"
property="dbWriter"
value="<%= session.getAttribute("DBWRITER")%>" />
</jsp:useBean>
Does anybody have any idea as to why i am getting this class cast
exception ?
Thanks.

Posted by Filip Hanik <ma...@filip.net>.
what happens if you translate the tags yourself to actual java code within
<% %> brackets,
do you still get classcast exceptions?

Re: Class cast exception ...
Posted by Mufaddal Khumri <mu...@wmotion.com>.
These were the values i got.
session DBWRITER = com.wavesinmotion.cw.classes.db.DBWriter@515185
session DBREADER = com.wavesinmotion.cw.classes.db.DBReader@bf1f08
This means that my DBREADER and DBWRITER are using the right classes.
Its still giving me a class cast exception. I thought maybe there is a
session object stored under the name locationHelper which is not of
type LocationHelper. But before this jsp is reached there is no
locationHelper attribute present in the session. I still cant figure
out where I am going wrong. Does anyone have any ideas ? The jsp code
is below and so is the stack Trace

Re: Class cast exception ...
Posted by Yoav Shapira <yo...@yahoo.com>.
Howdy,
Print out the value of session.getAttribute("DBREADER") before you set it: that
way you can see what its real runtime class is. It probably won't be that
locationHelper class you're trying to cast into...

Class cast exception ...
Posted by Mufaddal Khumri <mu...@wmotion.com>.
Made a typo in my previous email .. heres the corrected email:
I get the following error in tomcat:
java.lang.ClassCastException
at
org.apache.jsp.EditOffering_jsp._jspService(EditOffering_jsp.java:129)
I looked at EditOffering_jsp.java and it has this at line 129:
locationHelper =
(com.wavesinmotion.cw.classes.jsphelpers.LocationHelper)
pageContext.getAttribute("locationHelper", PageContext.SESSION_SCOPE);
which in the corresponding .jsp page is:
<jsp:useBean id="locationHelper"
class="com.wavesinmotion.cw.classes.jsphelpers.LocationHelper"
scope="session">
<jsp:setProperty name="locationHelper"
property="dbReader"
value="<%= session.getAttribute("DBREADER")%>" />
<jsp:setProperty name="locationHelper"
property="dbWriter"
value="<%= session.getAttribute("DBWRITER")%>" />
</jsp:useBean>
Does anybody have any idea as to why i am getting this class cast
exception ?
Thanks.

can you provide the complete stack trace, usually when a Class cast
exception happens it will also print out the class that fails,

have you imported the class in the JSP <% @ page import...?

no ... its just in one place neither have i reloaded the context. Even
if i did reload the context .. it should have found the correct .class
file since i have specified the complete path to it in the jsp useBean
tag right ?

any chance the class
com.wavesinmotion.cw.classes.jsphelpers.LocationHelper
resides in more than one place?
or did you reload the context?
