I have a JSF project and I already have an index.xhtml page which is working fine. When I try to add another XHTML page, for some reason it is not connected to my session scoped managed bean. I add the code in my new page but it doesn't work like my index.xhtml. I even copy and pasted the code from index and it still does not work. Any thoughts?
Here is some of the code I have in my new page:
Amount: <h:inputText value="#{transactionBean.amount}" style="color: Yellow; background: Teal;"/>
Price <h:inputText value="#{transactionBean.pricePaid}" style="color: Yellow; background: Teal;"/
Here is my web.xml:

You've mapped the faces servlet on /faces/* instead of *.xhtml. This means that you need to include /faces path in the URL to get the faces servlet to run.
So, you should not open the page by
http://localhost:8080/SharePortfolioJSF/companies.xhtml
but instead by
http://localhost:8080/SharePortfolioJSF/faces/companies.xhtml
Much better, however, is to just use *.xhtml as URL pattern of the faces servlet, so that you don't need to fiddle with virtual paths.
<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>*.xhtml</url-pattern>
</servlet-mapping>
<welcome-file-list>
<welcome-file>index.xhtml</welcome-file>
</welcome-file-list>
(note that your <session-timeout> of 30 minutes is the default already, just remove it)
From the comments:
Your second page isn't processed by the faces servlet. Your url pattern for the faces servlet is /faces/*. So all requests must contain the prefix /faces in order to get processed by the servlet.
It should work if you call your page with the following URL:
http://localhost:8080/SharePortfolioJSF/faces/companies.xhtml

In reference to the below questions asked on StackOverflow, I have included a class
annotated with #Configuration, #EnableResourceServer and #EnableWebSecurity.
The code is building fine but the control is not going in this class which have been annotated the aforementioned way.
Do I need resource server with Spring Security OAuth2?
I checked that Security filters were disabled in my web.xml. Now, I have enabled them. Even though I am not getting the intended result when I hit my request, I think the initial issue is fixed.
That issue got solved but now I am facing another issue:

You need to load the Spring context with org.springframework.web.context.ContextLoaderListener, not Log4jConfigListener (or try out Spring Boot)

In eclipse markers window I see following error twice: The servlet mapping "Faces Servlet" refers to a servlet that is not defined. Well, in my opinion it is defined right there. When I delete servlet-mapping nodes, error disappears, but the project is useless. I've tried to re-validate project and web.xml file, refresh dependencies from maven. I haven't succeeded in finding anything relevant in google search. Also, I used very similar web.xml file in another project(not maven) and there it worked fine.
How can I fix this error?
I learnt how to access session scoped sping beans from a jsp but got the following error:

I am building an application using Spring Framework 3.1
I am having my controllers mapped with url containing path variables that stands for some id.
But I don't want the user to tamper with the url and change the path variable value manually.
I want to restrict them from doing so.
I have already tried using the ShallowEtagHeaderFilter. But its not working the way it suppose to.
I don't know whether I missed any configuration for the filter or its not working at all.
here is my web.xml where I have configured the dispatcher servlet and filter.

Thanks in advance.
I don't understand how ShallowEtagHeaderFilter fits into this picture, I think you misunderstood its functionality. It's supposed to reduce network traffic by taking pages from the browser cache. That's a totally different scenario from yours.
Basically: if you don't want users to tamper with URLs, you will need to have a way to verify that the URL was created by your application, usually a checksum parameter of some sort with an algorithm that's not easy to guess.
e.g. /site/12/user/12345/aB where aB is calculated based on /site/12/user/12345. Now if the user changes the URL to /site/13/user/12345/aB the checksum is wrong and you can send a 404 or a 400 or whatever error you want to send.
I'd probably implement the checksum check as a Filter and write a utility method that creates URLs with checksum based on plain URLs (possibly you'll need a JSP tag as well)
