Can you copy it here your web.xml file? the content of web.xml is as below: | <?xml version="1.0" encoding="UTF-8"?> | <web-app id="WebApp_ID" 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/javaee/web-app_2_5.xsd"> | <display-name>Time</display-name> | <welcome-file-list> | <welcome-file>index.jsp</welcome-file> | </welcome-file-list> | <ejb-local-ref> | <ejb-ref-name>ejb/TimeBean</ejb-ref-name> | <ejb-ref-type>Entity</ejb-ref-type> | <local>net.sf.sample.TimeLocal</local> | </ejb-local-ref> | </web-app> | The xsd I use is 2.5 xsd, not 2.4.
