I tried to create a simple web app using ICEfaces and encountered a problem.
Here is the web page:
<!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:ui="http://java.sun.com/jsf/facelets"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:f="http://java.sun.com/jsf/core">
<h:head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<title>test</title>
</h:head>
<h:body>
<h:form>
<h:commandButton value="Action" action="#{test1.action}" />
</h:form>
</h:body>
</html>
Here is the backing bean:
#ManagedBean(name = "test1")
#SessionScoped
public class Test1 {
public Test1() {
}
public void action() {
System.out.println("action invoked");
}
}
And here is web.xml:

</context-param>
<listener>

</web-app>
The problem is that the size of the ViewState is large (checked with Firebug) and it grows each time I click "Action" button. After first request it is 32 KB, after second 61 KB, then 94 KB, 128 KB etc. (seems to me like it always saves the state of the previous request).
The behaviour changes when I set the value of javax.faces.STATE_SAVING_METHOD param to server - in this case all works fine and the ViewState remains small after each request (checked it on the server side using StateManager).
I'm using Mojarra 2.1.12 (also tried MyFaces - same result), ICEfaces 3.1.0 and Tomcat 7.0.29.
Thanks in advance.
ICEfaces requires server side state saving, so you should set the following:
<context-param>
<param-name>javax.faces.STATE_SAVING_METHOD</param-name>
<param-value>server</param-value>
</context-param>

Problem
My page renders all elements correctly. For example h:selectOneMenu and so on. But it seems that my Managed Bean is never instantiated as i don't see output on the console nor does the page render the content of foo.
I've read some other questions on SO:
Bean not instantiated - I don't beans.xml at all, I think.
JSF 2 managed bean does not get instantiated - I only have one ManagedBean which is referenced.
JSF Managed bean in jar not instantiated - My structure should be fine.
Does anyone know about issues with SessionScope maybe?
Is there something I'm missing? Or do I have to provide more, like the app-structure after deployment, more code, screenshots?
As it is #ViewScoped bean you have to implement Serializable as the implementation may decide to serialize session or view scoped beans whenever there is a need for that.
#ManagedBean(name="portal")
#ViewScoped
public class Portal implements Serializable{
In theory the NonSerializableException should occur only during the serialization itself, but maybe your environment set-up prevents the creation itself.
Anyway all your #SessionScoped / #ViewScoped should be marked like that by definition anyway.
Try using #javax.inject.Named instead of #ManagedBean.
I made a new IceFace project and tried to run it on my local host, however I got the following error message:

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>

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">

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

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: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>
