NoSuchMethod Excp on putValue() and setAttribute methods of HttpSession

           Summary: NoSuchMethod Excp on putValue() and setAttribute methods
                    of HttpSession
           Product: Tomcat 4
           Version: 4.1.9
          Platform: PC
        OS/Version: Windows NT/2K
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: Servlet & JSP API
        AssignedTo: tomcat-dev@jakarta.apache.org
        ReportedBy: ddemil@netscape.net


Hello there

I am running the following servlet code on Tomcat 4.1.10 :

public void doGet(HttpServletRequest request,
                    HttpServletResponse response)
HttpSession sess = request.getSession();
sess.setAttribute("Test", new Object());

the last line generate NoSuchMethod exception. I get the same error at run time 
if I used the deprecated putValue instead.

If I do this : 

java.lang.reflect.Method met[] = sess.getClass().getMethods();
for (int j = 0 ; j < met.length ; j++) {
  out.println("Method " + j + " of HttpSession is " + met[j].getName() 
+ "<BR>");
}
        
This is what I get :
...
Method 10 of HttpSession is putValue
...
Method 14 of HttpSession is setAttribute

I first thought that this could be related to Tomcat not supporting the correct 
version of the Servlet API but Tomcat 4.1.10 supports Servlet 2.3 in which 
those methods are supported but with the above reflection is not so clear 
anymore.

Many Thanks in advance for your help and advices.

Best Regards - Cecil Dijoux.
