It is quite strange when I add faces-config.xml file in WEB-INF in my project it cause me an error "RES_NOT_FOUND"
note: I have try <link type="text/css" rel="stylesheet" href="style.css" />
and it's working fine without the faces-config.xml. I also try to move it inside resources folder
I have try to use this code to add a css file for my .xhtml page
<h:head>
<h:outputStylesheet name="styles.css" />
</h:head>
it will generate the following
<link type="text/css" rel="stylesheet" href="RES_NOT_FOUND">
I am using JSF 2.2 + Google App Engine as I follow the tutorial from this site
http://java.wildstartech.com/Java-Platform-Enterprise-Edition/JavaServer-Faces/javaserver-faces-22/configuring-jsf-22-to-run-on-the-google-app-engine-using-eclipse
the tutorial went good except until I try to import a external files like .css, .js, and image files; and when I access it directly from the link like localhost:8080/style.css the css file will display correctly.
here is my code

Can anyone point which part of my project causes the error. I really want to use faces-config.xml without having a error. My whole point is, I cannot import css, js and other file with faces-config.xml present in my project. Is there any configuration or information I missed for JSF and GAE setup.

I am studying Google Cloud Endpoints and I have some doubts about configuration.
I already work with appengine, but endpoints it is a little confuse for me.
I did this example:

The doubts are:
Whats is the purpose of service_name? I did deploy of openapi.json and appengine module but in my Google Console still appear the name of my project in "service name".
this configuration: ENDPOINTS_CONFIG_ID, I can not see anywhere in my Google Console.
I would like that my endpoints receive requets in "enpoints-module"(appengine) that is appengine, not a default module.
All requests to endpoints happen through _ah/api ?
I am trying to do a request for this path:
https://myprojectid.appspot.com/endpointsmodule/echo/v1/echo
What is the correct value to ENDPOINTS_CONFIG_ID and ENDPOINTS_SERVICE_VERSION?
The exception when appengine starts:
repackaged.com.google.api.config.ServiceConfigException: Failed to fetch default config version for service 'myserviceprefix.endpoints.myprojectid.appspot.com'. No versions exist!
The Endpoints service name is host field set in the OpenAPI specification. This has to match both the environment variable ENDPOINTS_SERVICE_NAME and the endpoints.serviceName filter parameter.
I successfully deployed a Vaadin application, but when calling it I see ERROR : NOT_FOUND
I suppose that my default page is not found,because the default page is selected wrong.
Question:
How can I point (I suppose in my web.xml) to my default page?

Vaadin eclipse plugin does not create web.xml which works for vaadin application. In the book of vaadin you can find section about web.xml - https://vaadin.com/book/vaadin7/-/page/application.environment.html
following is basic servlet definition and mapping based on the book which works fine. Just change the UI parameter to point to your UI implementation
<servlet>
<servlet-name>myservlet</servlet-name>
<servlet-class>
com.vaadin.server.GAEVaadinServlet
</servlet-class>
<init-param>
<param-name>UI</param-name>

I'm learning Struts 2 for a project requirement and I've met some issues.
Following this tutorial at:
http://www.mkyong.com/google-app-engine/google-app-engine-struts-2-example/
And what I've done extra:
Added an index.jsp into the war folder
Changed web.xml to
<?xml version="1.0" encoding="utf-8"?>

</web-app>
Now, when I rebuild and loads
http://localhost:8888
Rather then seeing the content I should have in my index.jsp, I'm getting a
Error 404 There is no Action mapped for namespace [/] and action name [] associated with context path [].
Can someone point me to the right direction? I've seen some other similar questions in SO but their solutions do not work for this specific example of Struts 2 + GAE.
My struts.xml
<struts>
<package name="user" namespace="/User" extends="struts-default">
<action name="Login">
<result>pages/login.jsp</result>
</action>
<action name="Welcome" class="com.mkyong.user.action.WelcomeUserAction">
<result name="SUCCESS">pages/welcome_user.jsp</result>
</action>
</package>
</struts>
Folder structure
I cant post images so, http://i.imgur.com/KSPmaMr.png
Exact same libraries used for download
http://www[dot]mediafire[dot]com/?utliwvcmo63o8l7
ok ,i got your problem,
change your struts.xml to this
<struts>
<package name="default" extends="struts-default" namespace="/">
<action name="Login">
<result>pages/login.jsp</result>
</action>
<action name="Welcome" class="com.mkyong.user.action.WelcomeUserAction">
<result name="SUCCESS">pages/welcome_user.jsp</result>
</action>
</package>
</struts>
I guess this will work, because filterDispatcher search for struts.xml file in root folder if you put your struts.xml file in root directory.
#Eleazar I followed the mykong tutorial link that you mentioned in your question. There is no use of index.html as far as I see that tutorial. <welcome-list> file is used when the is no action mentioned on application startup.
On step:8 in that tutorial they has provided the url which is http://localhost:8888/User/Login.action you need to run the test. Its got nothing to do with file in welcome list...
UPDATE:
You are getting that error because you have added struts2 filter as /*, and your action namespace is for /User. There is not action namespace for /. Adding package with name="default" with namespace="/" i.e <package name="default" extends="struts-default" namespace="/"></package> will resolve you issue. It will hit <welcome-file>
I'm migrating an existing app from Tomcat to GAE. When testing locally, the xhtml pages are loaded as static pages. All processing is bypassed including my filter. However, if I reference a page that doesn't exist, my security filter forwards the request to the login.xhtml and the JSF/facelet renders fine.
Any idea why the xhtml pages are getting processed?

Update:
It works if I add the following mapping and refer to the page with .jsf extension. Referring to the .xhtml directly, still loads the source. Is it typical configuration to refer to .jsf extension for a .xhtml? If so, how do you configure the app so the source isn't available when accessed via .xhtml?

If I correctly understand your needs, you should add
<static-files>
<exclude path="/**.xhtml" />
</static-files>
in appengine-web.xml
If you skip this, your web browser will get reply from "static file server", not from JSF.
Trying out the hello world tutorial for googleapp engine. But get the 500 server error when I try to go on the deployed app.
