Thanks Martin for the reply. I have removed all calls to getParameter family of methods on the request object and I can still see the issue. I have checked all servlet filters - No processing has been done on request object. This issue is seen when content-type=application/x-www-form-urlencoded. Issue is not seen when content-type=text/xml.
Two questions A) How to know from where getParameter is being called from the code? B) Is it okay to use content-type=text/xml Regards, Swati -----Original Message----- From: Martin Gainty [mailto:mgai...@hotmail.com] Sent: Monday, July 27, 2009 5:23 PM To: Tomcat Users List Subject: RE: HttpServletRequest.getReader() returns nothing answered by markt here https://issues.apache.org/bugzilla/show_bug.cgi?id=47410 the 3.1 part of 2.5 Servlet Spec located at http://www.scribd.com/doc/7395371/JSP-Servlet-JSTL-Specification reads if request is a 1)http or https request 2)http method is a POST 3)content-type=application/x-www-form-urlencoded 4)servlet has made a initial call on any of getParameter family of methods on the request object if the (above) conditions are met the post-form-data will no longer be made available for reading by post objects InputStream do you expect the behaviour to be different than the spec Martin Gainty ______________________________________________ Verzicht und Vertraulichkeitanmerkung/Note de déni et de confidentialité Diese Nachricht ist vertraulich.
