please help me to get rid from this error . I have tried a lot but the error message is coming .Thanks in advance .
Check out your code in web.xml, you have written,
<servlet-mapping>
<servlet-name>Faces Servlet</servlet-name>
<url-pattern>*.faces</url-pattern>
</servlet-mapping>
So you can access your page by not index.jsp but index.faces
加载中,请稍侯......
