Eclipse & JSF & Tomcat 6: "FacesContext not found"

Using Eclipse Helios, I tried to start a JSF based project.

After having created a new workspace, I installed the web-tools-platform stuff. All using the "Install New Software" in the Help menu, this worked quite well.

To start developping for my project, I created a new project using the wizard, with which I downloaded and installed Tomcat 6.0 instance and runtime and configured it with the preset "JavaServer Faces v1.2 Project".

I created one single index.jsp-file (again with the wizard using the JSF-template) and put a JSF-outputText on it.

Deploy to the tomcat seems to work. When calling index.jsp in a browser, I get several times the following exception:

29.12.2010 18:24:00 org.apache.catalina.core.StandardWrapperValve invoke SCHWERWIEGEND: Servlet.service() for servlet jsp threw exception java.lang.RuntimeException: FacesContext not found at javax.faces.webapp.UIComponentClassicTagBase.getFacesContext(UIComponentClassicTagBase.java:321) at javax.faces.webapp.UIComponentClassicTagBase.setJspId(UIComponentClassicTagBase.java:228) at org.apache.jsp.login_jsp._jspx_meth_f_005fview_005f0(login_jsp.java:95) at org.apache.jsp.login_jsp._jspService(login_jsp.java:69) at org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:70) at javax.servlet.http.HttpServlet.service(HttpServlet.java:717) at org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:377) at org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:313) at org.apache.jasper.servlet.JspServlet.service(JspServlet.java:260) at javax.servlet.http.HttpServlet.service(HttpServlet.java:717) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:290) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:233) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:191) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:127) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:102) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:109) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:298) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:852) at org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:588) at org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:489) at java.lang.Thread.run(Thread.java:662)

Every single step I did was a standard-clicking-through-wizards process.

Any idea why this doesn't seem to work?

I can easily post screenshots or file excerpts if that helps, though I don't do it here to avoid overloading the question.

Edit: web.xml This file comes directly from eclipse, i left it unmodified except that I removed the description-tags in order to shorten the whole stuff:

Already tried setting the url-pattern to <url-pattern>/*</url-pattern> but then it's coming up with the exception "java.lang.NoClassDefFoundError: javax/servlet/jsp/jstl/core/Config"

Thanks and regards, Tobias

The user posted his answer some days ago was completely right (whyever the post was deleted).

It's necessary to add the jstl.jar-file to /WEB-INF/lib AND in eclipse, you need to add it to the build path

And I didn't understand that if the url-pattern is /faces/*, even if no such folder really needs to exist but you can call the file anyway, e.g. /faces/index.jsp

Thanks a lot
