Thank you,
You forgot the most important part:
Also post the contents of your userLogin.jsp file, your faces-config.xml file and your web.xml file.
please use the code button below to wrap your code
They, except for web.xml, are the SAME as on your site. But, if you wish, here they come.

First, comment out this line in your JSP file:
<f:loadBundle basename="com.jsfdemo.MessageBundle" var="bundle"/>does the page work without an exception? If so, go to your com.jsfdemo package, do you have any properties file named MessageBundle.properties or MessageBundle_<your language code>.properties? If not, you need to add one.
Per your advice commented out loadBundle.

You can uncomment the bundle line, the error with FacesContext is more a configuration issue.
Are you sure this project has JSF capabilities added to it? Please list all the JARs you have in your WEB-INF/lib directory. Something flaky is going on here.
Also, what version of Tomcat are you deploying this to?
Sure. Here’s what I have under lib:

j.bin, the problem is that you are trying to access your JSP page using the name of the file:
/userLogin.jspYou don’t want to do that, you want to access it using:
/userLogin.facesper your web.xml file you have mapped all .faces URLs to your JSFServlet, so you need to do that in order for JSF to process the request before you get to the JSP. I imported your project and did that and it worked fine.
