i have tried switching the the welcome-file-list to
<welcome-file-list>
<welcome-file>index.xhtml</welcome-file> <!--switched extension from html to xhtml -->
<welcome-file-list>
with this change my localhost will not crash, however I get a blank page (none of my JSF element shows up) I'm having a feeling it is because none of my JSf tags are getting parsed, however i don't really know where the problem is, can anyone please help me?
other information:
Im using Eclipse Java EE IDE for Web Developers
ICEFACES 3.3.0
Tomcat 3.0
Thanks.
update:
Changed my web.xml welcome-file-list to
<welcome-file-list>
<welcome-file>index.xhtml</welcome-file>
</welcome-file-list>
and changed my servlet-mapping to
<servlet-mapping>
<servlet-name>Faces Servlet</servlet-name>
<url-pattern>*.xhtml</url-pattern>
</servlet-mapping>
There is no crash now, but my JSF elements does not show up, i only get a blank page.
UPDATES:
Web.xml
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
<servlet-mapping>
<servlet-name>Faces Servlet</servlet-name>
<url-pattern>*.xhtml</url-pattern>
</servlet-mapping>
I have tried .jsf and .xhtml inside the url-pattern tag both no luck
index.jsp
<html>
<head>
</head>
<body>
<%
//response.sendRedirect("./index.jsf");
%>
<jsp:forward page="main.jsf"/>
</body>
</html>
after Getting my page to load up, it becomes blank, so i right click on my page and view source, and this is what i found...

Why does my BootsFaces not render anything?

I am fairly new to Coding with Frameworks. I want to build a Website using JSF and found BootsFaces as a Framework. So I downloaded BootsFaces and followed https://www.bootsfaces.net/quick-start.jsf to get everything going. I added the .jar into the Java Build Path and started a Project like the quick-start. So far so good. Then I wanted to implement some more "advanced" stuff. So I tried to add https://showcase.bootsfaces.net/forms/buttonGroups.jsf just to test if everything works. It didn't, If I copy
<b:buttonGroup>
<b:button value="Left" />
<b:button value="Middle" />
<b:button value="Right" />
</b:buttonGroup>
My Site doesnt show anything when it loads.
Here is my index.xhtml

Did I forget/not see something very basic? Or isn't BootsFaces even supposed to work like this?

Prettyfaces custom URL is not hitting

I am using pretty faces with jsf 2.0 but it is not showing output when hitting the url. I added the prettyfaces-core-3.3.2.jar. Here is the configurations i have made.

JSF is not working

I am beginner in JSF. I found one example in the Internet but it is not working besides the author said that it was right. Here it is:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:h="http://xmlns.jcp.org/jsf/html"
xmlns:ui="http://xmlns.jcp.org/jsf/facelets"
xmlns:f="http://xmlns.jcp.org/jsf/core">
<f:view>
Label Text:
<h:outputLabel value="Hello, world"/>
</f:view>
</html>
After deploying into Tomcat, I can see only "Label Text" in Chrome/Mozila. I am opening code page throught browser and see the next:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:h="http://xmlns.jcp.org/jsf/html" xmlns:ui="http://xmlns.jcp.org/jsf/facelets" xmlns:f="http://xmlns.jcp.org/jsf/core">
<f:view>
Label Text:
<h:outputLabel value="Hello, world"></h:outputLabel>
</f:view>
</html>
What is problem of mine?
Here is my web.xml
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee"

1) Probably you forget to configure JSF stuffs in web.xml.
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
version="3.0">
<servlet>
<servlet-name>Faces Servlet</servlet-name>
<servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>Faces Servlet</servlet-name>
<url-pattern>*.html</url-pattern>
<url-pattern>*.xhtml</url-pattern>
<url-pattern>*.jsf</url-pattern>
</servlet-mapping>
<context-param>
<param-name>javax.faces.PROJECT_STAGE</param-name>
<param-value>Development</param-value>
</context-param>
<context-param>
<param-name>javax.faces.DEFAULT_SUFFIX</param-name>
<param-value>.xhtml</param-value>
</context-param>
<welcome-file-list>
<welcome-file>index.html</welcome-file>
</welcome-file-list>
</web-app>
2) another option namespace can be wrong. "xmlns.jcp.org" is jsf 2.2 namescapes. are you sure to have jsf 2.2 dependencies? please try this sample:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:f="http://java.sun.com/jsf/core">
<h:body>
Label Text:
<h:outputLabel value="Hello, world"/>
</h:body>
</html>

</error-page>
However when an exception happens the user is just redirected to the default 500 error page.
The redirection will only work if I move error pages out of the WEB-INF folder
/WEB-INF/pages/errors/pageNotFound.xhtml --> /pages/errors/pageNotFound.xhtml
But this would mean that the error page can now be accessed directly. But in the Omnifaces showcase this should be possible. I don't know what I am missing please help...
Here is the web.xml of the Omnifaces showcase that shows that error pages in the WEB-INF is possible.

Summary
Redirect to error pages work if outside the WEB-INF.
Showcase shows that it should be possible.
I need help....
Thank you for your time
EDIT
It seems that "Redirect to error pages work if outside the WEB-INF." is not always true.
This error page will be displayed if outside of WEB-INF
<?xml version="1.0" encoding="ISO-8859-1" ?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"

xmlns:f="http://java.sun.com/jsf/core"
xmlns:p="http://primefaces.org/ui">
<h:body>
<h1>#{"XXXXXXXX"}</h1>
</h:body>
</html>
This error page will not be displayed even if outside of WEB-INF. This Will result in the default 404 Page
<?xml version="1.0" encoding="ISO-8859-1" ?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

xmlns:p="http://primefaces.org/ui">
<h:body>
<h1>ZZZZZZZZZ</h1>
</h:body>
</html>

It seems that the FacesExceptionFilter is actually working if I place an EL expression or jsf component on the jsf page.
For some reason this error page will not work and will produce The default 404 page.
<?xml version="1.0" encoding="ISO-8859-1" ?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

xmlns:p="http://primefaces.org/ui">

</h:body>
</html>
However this error page will work.

I get a blank page when i upload my jsf page to server host

I wrote a simple jsf web app on eclipse. My web app works fine when I run it on tomcat 7 server in eclipse. Now I am in the process of deploying it to a server host name = cheetah.arvixe.com.
to do this I have exported my web app as a war file and have unzipped this war file in the public_html folder of the arvixe server.
When I go to my website on my browswer, i get a blank page. When I look at the page source I see my index.xhtml with the jsf tags. I want to know why my page is not showing. Any ideas?
Here is my index.html code:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"

<ui:composition template="/WEB-INF/templates/BasicTemplate.xhtml">
<ui:define name="content">
<h:form>
<h:panelGrid columns="2">
<h:outputText value="Name"></h:outputText>
<h:inputText id="userid" value="#{user2.userId }"></h:inputText>
<h:outputText value="Password"></h:outputText>
<h:inputSecret id="password" value="#{user2.pincode}"
required="true" requiredMessage= "#{vm['loginBean.password']}">
<h:messages for="password" style="color:red" />
</h:inputSecret>
</h:panelGrid>
<h:commandButton value="Register" action="query_results"></h:commandButton>
</h:form>
</ui:define>
</ui:composition>
</html>
and here is my web.xml code:
