These were the values i got. session DBWRITER = [EMAIL PROTECTED] session DBREADER = [EMAIL PROTECTED]
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
<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>

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...

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.
