Tomcat exception - java.net.ConnectException: Connection refused: connect

Tomcat itself (v 7.0.54) is working fine, I can access and work with the manager-gui app. However, my main web app just won't work. I haven't modified the default server.xml or web.xml file at all. The WAR file (in my case, pp.war) is also automatically deployed. I have read other SO threads that pertain to port issues, but I'm stumped as the manager app is working fine. The exception shown in the browser is:

EDIT:

In faces-config.xml, version information is listed in the root node as:

<faces-config xmlns="http://java.sun.com/xml/ns/javaee"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-facesconfig_2_0.xsd"
    version="2.0>

In web.xml, the servlet configuration looks like this:

<servlet>
    <servlet-name>Faces Servlet</servlet-name>
    <servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
  </servlet>

Also, the web.xml root node:

<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xmlns="http://java.sun.com/xml/ns/javaee" 
xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" 
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" 
version="2.5">

And the servlet display nodes:

<servlet-mapping>
    <servlet-name>Faces Servlet</servlet-name>
    <url-pattern>*.jsf</url-pattern>
  </servlet-mapping>
  <servlet-mapping>
    <servlet-name>Faces Servlet</servlet-name>
    <url-pattern>*.jsp</url-pattern>
  </servlet-mapping>
  <servlet-mapping>
    <servlet-name>Faces Servlet</servlet-name>
    <url-pattern>*.xhtml</url-pattern>
  </servlet-mapping>
  <servlet-mapping>
    <servlet-name>PhpJavaServlet</servlet-name>
    <url-pattern>*.phpjavabridge</url-pattern>
  </servlet-mapping>
  <servlet-mapping>
    <servlet-name>PhpCGIServlet</servlet-name>
    <url-pattern>*.php</url-pattern>
  </servlet-mapping>

Does the web app connect to a website on a different target site at launch time? Check it. It looks like a http connection exception in the application, unless it is tomcat iteslf bug.

It seems that your application is trying to connect the url through the HttpClient, so please check your network settings i.e. proxy settings, make sure your application can access the internet!

I don't think your JSF servlet is configured correctly. If you are using Tomcat 7 yours web.xml

must specify the Servlet 3.0 specification.

<web-app xmlns="http://java.sun.com/xml/ns/javaee"  
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  
         xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
                             http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"  
         version="3.0">
