StartupServletContextListener crashes Tomcat container

Greetings

I just joined this list tonight, as I have only started messing around
witth Java Server Faces and Tomcat.
I am working through some tutorials very slowly and I seem to be able to
work the JSP side of things
fairly well, but I cannot get Java Server Faces to work at all. I will skip
the tortuous details of how I got
to this point and simply say that I get the following error when I try to
add the StartupServletContextListener
to the web.xml file

Dec 7, 2005 4:48:43 PM org.apache.catalina.core.StandardContext start
SEVERE: Error listenerStart
Dec 7, 2005 4:48:43 PM org.apache.catalina.core.StandardContext start
SEVERE: Context [/samples] startup failed due to previous errors

As I point out above, starting Tomcat works until I add the <listener>
node. Without it, or so I gather from
googling this all day, the faces page won't work, but the server starts up
at least.

So, what exactly am I missing? (I hope this is enough info)

Hi,

please make sure that you inluded the myfaces libraries to your webapp, since
they are not in your common\lib.
The following links explain how to get started with myfaces (which is just an
implementation of JSF):

http://wiki.apache.org/myfaces/Installation_and_Configuration
http://wiki.apache.org/myfaces/Getting_Started

Take care,

Kurt

Kurt,

Thanks for your response. I had unzipped the file in the wrong place.

I have followed the instructions in the two links you sent me and have
conquered this problem to arrive at another one, which may or may not
be related. With the following JSP code

<%@ page contentType="text/html" %>
<%@ taglib uri="http://java.sun.com/jsf/html" prefix="h" %>
<%@ taglib uri="http://java.sun.com/jsf/core" prefix="f" %>

<f:view>
<h:form>
From: <h:inputText size="8" />
</h:form>
</f:view>

I get the following error
javax.servlet.ServletException:
org/apache/commons/el/ExpressionEvaluatorImpl
javax.faces.webapp.FacesServlet.service(FacesServlet.java:121)

The difference (and source of joy) is that now I am at least getting this
in the browser instead of in the startup panel in Tomcat.
My web.xml file is still as below and my newly cleaned lib directories are

common\lib
jasper-compiler-jdt.jar
jasper-compiler.jar
jasper-runtime.jar
jsp-api.jar
naming-factory-dbcp.jar
naming-factory.jar
naming-resources.jar
sample_app_1_0_2.jar
servlet-api.jar
standard.jar

sample\WEB-INF\lib
commons-beanutils.jar
commons-collections.jar
commons-digester.jar
commons-el.jar
commons-logging.jar
custom_jsf_lib_1_0_2.jar
jstl.jar
myfaces-all.jar
myfaces-api.jar
myfaces-impl.jar
struts.jar

Is this error still connected to the ServletContext problem from before?

Thanks again
Jeff

Jeff,

the error message just say that the exception occured in
FacesServler.service but doesn't tell you anything about the reason.
If you'd like to find out, you have to look into tomcat's log file for
some stacktrace telling you what caused the crash.

But anyway, since you are having trouble to get "the whole JSF thing"
running, I'd recommend you to give it a fresh start and look into one of
the different tutorials or quickstart applications like Equinox or
AppFuse. You can find them at https://equinox.dev.java.net/ and
https://appfuse.dev.java.net/ respectively.
Once these apps are running, you know your setup is fine and can start
developing your own application.

Hope that helps,

Kurt
