java.lang.StackOverflowError Running JSF 2 example on Weblogic 12c

问题

I followed the very basic tutorial found here example and cannot seem to get past the following error:

Error 500--Internal Server Error 
java.lang.StackOverflowError
    at weblogic.servlet.internal.ServletResponseImpl.addHeader(ServletResponseImpl.java:567)
    at javax.servlet.http.HttpServletResponseWrapper.addHeader(HttpServletResponseWrapper.java:200)
    at javax.servlet.http.HttpServletResponseWrapper.addHeader(HttpServletResponseWrapper.java:200)
    at javax.servlet.http.HttpServletResponseWrapper.addHeader(HttpServletResponseWrapper.java:200)
    at javax.servlet.http.HttpServletResponseWrapper.addHeader(HttpServletResponseWrapper.java:200)

Pressing shift + F5 a couple times I can generate a slightly different stacktrace as follows:

Error 500--Internal Server Error 
java.lang.StackOverflowError
    at com.sun.faces.application.ViewHandlerResponseWrapper.setStatus(ViewHandlerResponseWrapper.java:88)
    at javax.servlet.http.HttpServletResponseWrapper.setStatus(HttpServletResponseWrapper.java:224)
    at com.sun.faces.application.ViewHandlerResponseWrapper.setStatus(ViewHandlerResponseWrapper.java:88)
    at javax.servlet.http.HttpServletResponseWrapper.setStatus(HttpServletResponseWrapper.java:224)

I have exhausted several hours searching the web and constructing new projects with no luck. I understand that the StackOverflowError is produced from bad recursion calls and infinite loops, however I can't see this as the case here.

My current dev stack is eclipse juno, m2e-wtp, weblogic 12c, Java EE 6 using JSF 2.1

I am hoping it is something simple like a missing dependency or weblogic plugin in my pom.xml. Any help would me MUCH appreciated.

UPDATE 1: If I export the war file using eclipse (Right click the project -> Export -> WAR file) then manually deploy it via the weblogic admin counsel the app works as expected. More specifically the version of eclipse is the one from oracle (oepe-12.1.1.2.1-juno-distro-win32-x86_64.zip).

The OP wrote:

Solved the problem! After adding JSF 2.1 in the pom.xml the JSF 2.1 checkbox was checked in project facets, however it did not add the faces-config.xml to the project. I simple created a new xml file named faces-config.xml under the webapp --> WEB-INF folder and added the following xml:

<?xml version='1.0' encoding='UTF-8'?>
<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_1.xsd" version="2.1">

<application></application>

</faces-config>

I Hope this helps others!
