I'm using JSF 2 to create a web app with internationalization, with a switch link between English and French. When the page is in English, the page will have a French link; when the page is in French, it will have a English link. But when the page language gets switched, the link is not refreshed, till I refresh the page.
I googled this error, it says its caused by the conflict. Tomcat has already had this jar, I then checked server lib folder, it is there, but how could my Java class reference to there?? If I remove jsp-api.jar from my own lib directory, it's a compilation error, if I ignore it and still build war file and deploy it, its still failed to start the application as error now is 'INFO: validateJarFile(/usr/local/apache-tomcat-6.0.26/webapps/my_project/WEB-INF/lib/servlet-api.jar) - jar not loaded. See Servlet Spec 2.3, section 9.7.2. Offending class: javax/servlet/Servlet.class
