Could you pls let me know How u solved this ? -----Original Message----- From: Kristofer Arnar Einarsson [mailto:[EMAIL PROTECTED] Sent: Friday, June 16, 2006 8:07 AM To: [email protected] Subject: Re: servlet-api Hi I have a very simple Hello World portlet which works fine with web app 2.3 in web.xml: <!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd";> <web-app> However, when I try to use web app 2.4 it seems to break: <?xml version="1.0" encoding="UTF-8"?> <web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd";> I have a servlet-api jar which has both 2.3 and 2.4. The error that I get in the wsrp log is attached. Using only: <web-app version="2.4"> seems to be ok but I am not sure it is actually using 2.4 or just skipping the version attribute. I have yet to add 2.4 features in my portlet.
