In IntelliJIdea, i've created a little application with just default pages auto created by ide. I've added two frameworks: spring (3) and JSF 2. The app level is java ee 2.5, because I want to deploy on a Tomcat 6.0.
I installed an Apache Tomcat 6.0, created an administrator user, and tested, it works.
But when I deploy the simple application, it seems to deploy it correctly, but accessing it, the browser gives the error:
Simple jsp page
12: <body>

java.lang.RuntimeException: FacesContext not found
The JSF component is complaining that the FacesContext cannot be found. The FacesServlet is the one responsible for creating it. So it has clearly not run. You need to ensure that the request URL as you entered in the browser address bar matches the URL pattern of the FacesServlet as it is been definied in the webapp's web.xml file (and that it is been definied in the web.xml). If it is for example
<url-pattern>*.jsf</url-pattern>
then you need to ensure that the request URL is
http://localhost:8080/contextname/page.jsf
and thus not
http://localhost:8080/contextname/page.jsp
If the request URL matches the URL pattern of the FacesServlet, then it will be invoked and it will do all the JSF jobs.
Unrelated to the problem: why the choice for JSP when you're using JSF2? Why not using its superior successor Facelets instead?
I encountered the same problem. The solution for me was to use the URL "http://localhost:8080/index.faces".

I'm building a web application running on Liberty profile 8.5, with JSF 2.0 feature enabled (jsf-2.0 in server.xml) and BIRT integration in the web app.
The web application includes all BIRT needed libs in WEB-INF/lib folder, but the only way to make it working (specially for chart report) is to set the classloader to 'parentlast' in the server.xml:
<webApplication contextRoot="MyApp" id="MyApp" location="MyApp.war" name="MyApp">
<classloader delegation="parentLast"/>
</webApplication>
In this way, I correctly see charts and reports.
But the 'parentlast' setting makes JSF not working, with this exception:
[ERROR ] SRVE0315E: An execption occurred:
com.ibm.ws.webcontainer.webapp.WebAppErrorReport:
javax.servlet.ServletException: SRVE0207E: Uncaught initialization

at [internal classes] Caused by: javax.servlet.ServletException:

more
Caused by: java.lang.IllegalStateException: No Factories configured for this Application. This happens if the faces-initialization does not work at all - make sure that you properly include all configuration settings necessary for a basic faces application and that all the necessary libs are included. Also check the logging output of your web application and your container for any exceptions!
If you did that and find nothing, the mistake might be due to the fact that you use some special web-containers which do not support registering context-listeners via TLD files and a context listener is not setup in your web.xml.
A typical config looks like this;
<listener><listenerclass>org.apache.myfaces.webapp.StartupServletContextListener</listener-class>
</listener>
Without the parentlast setting, the JSF pages are correctly shown, but BIRT charts don't work.
I understand this behaviour, as the parentlast classloading makes the application seeing at first the application libs, where JSF is not included (it's loaded at server scope).
Any suggestion?
Thank you in advance!
I am trying to deploy JSF 1.2 application on WAS 8.5 server. But it is throwing below error on deployment.
Note: In the WAS admin, Under JSF implementation use console, I have selected the "Sun Reference Implementation 1.2 " option . But still problem persist.

You should restart the application server (not just the app). You should also make sure jsf-api.api and jsf-impl.jar are not in WEB-INF/lib of your app.
I was trying to enable EL 2.2 on tomcat 6.0.41 on windows 7.
I read this: http://wiki.apache.org/myfaces/HowToEnableEl22
and this: JSF - call method with parameter (tomcat6)
and this: org.apache.jasper.JasperException: The function test must be used with a prefix when a default namespace is not specified
and also this: Can EL 2.2 capable JSF web applications be deployed to shared Tomcat 6 hosting environment?
and tried to follow them all but with no luck, I still get the following error:
org.apache.jasper.JasperException: /DashBoard.jsp(234,7) The function
setSelectedExperiment must be used with a prefix when a default
namespace is not specified
on this line of code:
action="#{dashBoardController.setSelectedExperiment(experiment)}"
I did the following:
downloaded the el jars from here:
http://download.java.net/maven/2/javax/el/el-api/2.2/el-api-2.2.jar
http://download.java.net/maven/2/org/glassfish/web/el-impl/2.2/el-impl-2.2.jar
and put them under WEB-INF/lib
I removed el-api.jar from tomcat6/lib
i added this to web.xml:
<context-param>
<param-name>com.sun.faces.expressionFactory</param-name>
<param-value>com.sun.el.ExpressionFactoryImpl</param-value>
</context-param>
all according to the guidelines in apache wiki
Yet, as I said, I get the error above.
I am planning to use Cometd library in my application that runs on JBoss AS 6. Therefore I downloaded cometd 2.4.0 and tried to deploy example war (from cometd-demo/target) to my AS. I was aware that this was not possible without modifications, so I did the changes in web.xml:
Changed to servlet 3.0 in web-app tag (it is originally 2.5). Used complete tag from CometD faq answer. Also uncommented continuation filter that was already in web.xml, based on this description
Based on faq answer, added async-supported tag. However, this causes problems: if I just uncomment it, web.xml can't be parsed. I found out that this is due to order of tags in XML, so moved async-supported tag down the order, just after load-on-startup tag. However, Jboss still throws exceptions:
ERROR
[org.apache.catalina.core.ContainerBase.[jboss.web].[localhost].[/cometd-demo-2.4.0].[cometd]]
Servlet.service() for servlet cometd threw exception:
java.lang.IllegalStateException: The servlet or filters that are being
used by this request do not support async operation
ERROR
[org.apache.catalina.core.ContainerBase.[jboss.web].[localhost].[/cometd-demo-2.4.0].[cometd]]
Servlet.service() for servlet cometd threw exception:
java.lang.ClassNotFoundException:
org.eclipse.jetty.server.AbstractHttpConnection from
BaseClassLoader#12a54b
Complete web.xml file that I use is here.
Example runs no my Jboss despite all errors reported, but by watching firebug, I can see that it does quick pooling instead of long pool. It seems that server thinks that browser has multiple connections open, which is not the case (see JSON below):
[{"id":"137","successful":true,"advice":{"interval":2000,"reconnect":"retry","multiple-clients":true,"timeout":20000},"channel":"/meta/connect"}]
Did anyone managed to make examples work with JBoss as6 and how? What I did wrong here?
remove:
<!-- Portability Filter, needed only to run on non Jetty or non Servlet-3.0 containers -->
<filter>
<filter-name>continuation</filter-name>
<filter-class>org.eclipse.jetty.continuation.ContinuationFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>continuation</filter-name>
<url-pattern>/cometd/*</url-pattern>
</filter-mapping>
from web.xml
I have the same setup and the same problem even if I remove continuation filter from web.xml.
I've found a thread on cometd-users group complaining about multiple-client issue on Tomcat 7 and the cause seems to be a Tomcat bug around Content-Type that is not set to "application/json".
However I've inspected packets and on JBossAS6 the content-type is correctly set on server responses.
UPDATE
I've give a try using Jetty 7 and the problem disappeared. The "multiple-clients" issue affects Tomcat as well as JBoss6 AS
We have an application which uses JSF2 and Spring. The application works fine when deployed. But this happens if I went through the following steps:
Open the login page of the application.
Redeployed the application on the server.
Tried to login using the previously opened login page, and it shows the following exception:

If I click on the first login page and then enter the login details the application does not break. This only occurs if I try to use the previously loaded login page with the newly deployed application.
Anyone knows the answer?
This one should have been thrown as a ViewExpiredException. It's a bug which started to manifest in Mojarra 2.0.3 and is been fixed in Mojarra 2.1.0. See also issue 1762 (note that Mojarra 2.1.0 doesn't work on Tomcat/Jetty, use at least Mojarra 2.1.1 then).
Basically, when Mojarra fails to build or restore the view, then it usually throws a specific enough exception, but due to this bug, a valid view was incorrectly been expected later in the code which in turn results in IllegalArgumentException: null source. The possible real cause would have been that the view contains a simple XML syntax error, such as a missing tag or broken attribute value, for which Mojarra would usually have thrown a FaceletException with a very detailed message with line number and position and such.
To prevent the ViewExpiredException, you would have to refresh the page by a GET request before doing any actions on it. If you're using a Mojarra version where this bug does not manifest (e.g. 2.0.2 or older, or 2.1.0 or newer), then you could gracefully handle it with an <error-page> in web.xml on the particular exception and provide a custom error page wherein the enduser is informed that the session has been expired, along with a link to the initial request URI.
This looks like http://java.net/jira/browse/JAVASERVERFACES-1758
which is not fixed in Mojarra 2.1.x
As long as javax.faces.PARTIAL_STATE_SAVING is set to false you'll receive that java.lang.IllegalArgumentException. If you set javax.faces.PARTIAL_STATE_SAVING to true (and you know what you are doing) you will get the "good old" javax.faces.application.ViewExpiredException back.
In my case turned out i had missing end tag in xhtml file for one of the jstl calls. i was using choose tag and one of the when tags in between choose did not have an end tag
