Bug in HttpServletRequest

Question

Bug in HttpServletRequest
I came across this bug when I was developing my project on OC4J which is latest Orion.
I store the HttpServletRequest object in session
(Set Request is called com.evermind.server.http.EvermindHttpServletRequest@1bfb30)
and when I retrieve it later I get
(Previous request got from constants com.evermind.server.http.EvermindHttpServletRequest@1bfb30)
which is correct but problem start when I called getParameterNames() on this object.
When I make call
Enumeration enum = req.getParameterNames();
and I print this object in else I get
Request Element object is not null java.util.Collections$6@52b01b
I think it should return me Enumeration while it gave me Collection. Same code is working on
weblogic but it is giving problem on Orion.
Does anybody have clue or this is a bug.
Code Snippet is
Enumeration enum = req.getParameterNames();
if(enum==null)
System.out.println("Request Element object is " + enum);
else
System.out.println("Request Element object is not null " + enum);
while (enum.hasMoreElements())
System.out.println("Request Element " + enum.nextElement());
}

Hi Ashok,
When I was trying to port the application from weblogic to this ..I came across this.
Though it doesn't give error when I say
Enumeration enum = req.getParameterNames();
but when I print the object it is Collection and if I try to typecast the returned object it throws error. When I print
if(enum==null)
System.out.println("Request Element object is " + enum);
else
System.out.println("Request Element object is not null " + enum);
...I get collection. This problem is strange.
I changed my code and now I doesn't store the HttpRequest in session.(workaround)
Thanking you in anticipation,
regards,
Vijay
