There seems to be a bug in the version 3.2.3 of tomcat 

Due to which , I am getting this exception
java.lang.ClassCastException: ClassTeacher.Registration.RegSession
at com.MindShaper.ClassTeacher.Apps.HigherEd.IIFT.Users.ProgramBuy.doPost
(ProgramBuy.java:44)
at javax.servlet.http.HttpServlet.service(HttpServlet.java:760)

Plz see the link below. My problem is similer.

this exception shows up whenever I am trying to cast an Object obtained from 
session after uploading a servlet.The details are same as discussed in the 
above link. Plz note that we need auto reloading of the servlets so it cannot 
be turned false.
Please note that this problem would be temporarily resolved once you restart 
the tomcat, but will show up as soon as I upload a servlets.


The source code of the TestServlet. 

HttpSession sess=req.getSession(false);
Object o=sess.getValue(SessionObjectDefines.KEY_REGINFO);
out.print("o.getClass() "+o.getClass()+"<br>");
ClassTeacher.Registration.RegSession regSess = 
(ClassTeacher.Registration.RegSession)o;
On running this , we see this o.getClass() prints the fully qualified class 
name as 
ClassTeacher.Registration.RegSession which is same as the object I am trying to 
cast to. 

counter is ...11
o.getClass() class ClassTeacher.Registration.RegSession

Error: 500
