InputText in form for JSF 2.3.1

I would like to have a input text field for a form in JSF 2.3.1 (with J2E) but I have nothing on my page, only the text H1 ...
I searched on other posts, they said because the alias should be com.sun but I don't know how to change it :(
Every comments are welcomed :)
Edit: I can't see h:commandButton neither

The output screen is
How do I have to configure my project to see the spinner?

I think you should read the documentation for a spinner in Primefaces. Spinner is primarily used to increment/decrement the value of input text. You also need to create a bean defining the setter/getter for the values.
Do have a look https://www.primefaces.org/showcase/ui/input/spinner.xhtml
Just for reference:
<h:outputLabel for="basic" value="Basic Spinner: " />
<p:spinner id="basic" value="#{spinnerView.number1}" />
Hope it helps!!

Primefaces FileUpload not working in Spring Boot

As it's specified above, I'm configuring the project to run in a tomcat 7.0.57 (Servlet 3.0 compatible) launcher. All the JSF functions are properly working, but the problem is I can't get the Primefaces p:fileUpload component work, neither the basic or the advanced versions. The file upload listener doesn't get invoked and no error thrown.
That's my bean's code:
#ManagedBean
#javax.faces.bean.ViewScoped
public class Bean {
public void handleFileUpload(FileUploadEvent event) {
FacesMessage message = new FacesMessage("Succesful", event.getFile()
.getFileName() + " is uploaded.");
FacesContext.getCurrentInstance().addMessage(null, message);
System.out.println("Uploaded!");
}
}
And that's how my xhtml file looks like, under a template:
<ui:composition template="/WEB-INF/template.xhtml"
xmlns="http://www.w3.org/1999/xhtml"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:p="http://primefaces.org/ui">
<ui:define name="content">
<h:form>
<p:fileUpload fileUploadListener="#{bean.handleFileUpload}" />
</h:form>
</ui:define>
</ui:composition>
Nothing special about the code at all, it must be a server configuration issue. When I drop the file and click on upload, the FacesServlet gets hit. So the request is performed and no javascript errors shown. But when I perform a debugging into the InvokeApplicationPhase class, where my method should be invoked, I find no events to be processed. So the FileUploadEvent is not being attached to the cycle.
Furthermore, that's the debugging stack of another project that properly performs the file upload with Tomcat 7 and that JSF version:
Here the NativeFileUploadDecoder is being called. However that's not happening in my Spring boot project and no method below FileUpload#visitTree is invoked.
I tried other choices and found out that when I use some <h:form enctype="multipart/form-data"> none of the action methods for components inside are invoked, even when I place a plain h:commandButton.

Finally, I got it working using the Apache Commons library. Similarly that what we might do in a standard web.xml file, that's my context initializer:
#Bean
public ServletContextInitializer initializer() {
return new ServletContextInitializer() {
#Override
public void onStartup(ServletContext servletContext)
throws ServletException {
servletContext.setInitParameter("primefaces.THEME", "bluesky");
servletContext.setInitParameter(
"javax.faces.FACELETS_SKIP_COMMENTS", "true");
servletContext.setInitParameter(
"com.sun.faces.expressionFactory",
"com.sun.el.ExpressionFactoryImpl");
servletContext.setInitParameter("primefaces.UPLOADER",
"commons");
}
};
}
I explicitly tell Primefaces to use the commons uploader, like said in docs (the other choice is to use native, which is not working).
Then, just adding this two dependencies to the project, we're ready to go:
<dependency>
<groupId>commons-fileupload</groupId>
<artifactId>commons-fileupload</artifactId>
<version>1.3</version>
</dependency>
<dependency>
<groupId>commons-io</groupId>
<artifactId>commons-io</artifactId>
<version>2.2</version>
</dependency>
I keep the thread opened for some response based in the native mode.

How to use PrimeFaces p:fileUpload? Listener method is never invoked or UploadedFile is null

It could be also necessary to transfer xml filter configuration to Java-based Config :
<filter-mapping>
<filter-name>PrimeFaces FileUpload Filter</filter-name>
<servlet-name>Faces Servlet</servlet-name>
</filter-mapping>
to your #Configuration
#Bean
public FilterRegistrationBean FileUploadFilter() {
FilterRegistrationBean registration = new FilterRegistrationBean();
registration.setFilter(new org.primefaces.webapp.filter.FileUploadFilter());
registration.setName("PrimeFaces FileUpload Filter");
return registration;
}
in combination with the above answer it work for me

Just to put my two cents, with Spring boot 1.4.2.RELEASE, Primefaces 6.0, OCP Soft rewrite 2.0.12.Final, JSF 2.1.29-08 and application deployed on Tomcat 8, I also need to disable spring hiddenHttpMethodFilter.
#Bean
public FilterRegistrationBean hiddenHttpMethodFilterDisabled(
#Qualifier("hiddenHttpMethodFilter") HiddenHttpMethodFilter filter) {
FilterRegistrationBean filterRegistrationBean = new FilterRegistrationBean(filter);
filterRegistrationBean.setEnabled(false);
return filterRegistrationBean;
}
I have spent with this issue almost two days and as last thing I have tried to disable spring filters one by one, so I hope it will help someone.

After deployment at OpenShift, opening JSF page ends up in "The XML file does not appear to have any style information associated with it" error

I made basic web service with two pages. I used primefaces lib and jsf. On my locallhost (jboss 6.x) the webpage works correctly. If I deployed it to openshift It looks like on the screenshot:

You're attempting to access the index.xhtml. However, your faces servlet mapping indicates that it should be /context-root/faces/index.xhtml
Also note that open shift is based on JBoss AS 7, not JBoss AS 6. If you want to verify that your application will work locally you should switch to AS7.

Warning: This page calls for XML namespace http://primefaces.prime.com.tr/ui declared with prefix p but no taglibrary exists for that namespace

I'm trying to start with Primefaces 2.2.1, but I can't. I have the following definition in pom.xml:
<repository>
<id>prime-repo</id>
<name>PrimeFaces Maven Repository</name>
<url>http://repository.primefaces.org</url>
<layout>default</layout>
</repository>
<dependency>
<groupId>org.primefaces</groupId>
<artifactId>primefaces</artifactId>
<version>2.2.1</version>
</dependency>
But I recevie the following error message:
Warning: This page calls for XML namespace http://primefaces.prime.com.tr/ui declared with prefix p but no taglibrary exists for that namespace.
with this simple code:
<?xml version='1.0' encoding='UTF-8' ?>
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:h="http://java.sun.com/jsf/html"

<h:head>
<title>Facelet Title</title>
</h:head>
<h:body>
Hello from Facelets
<p:editor />
</h:body>
</html>

Include the tag lib as :
xmlns:p="http://primefaces.org/ui"
And the dependency in pom.xml as :
<dependency>
<groupId>org.primefaces</groupId>
<artifactId>primefaces</artifactId>
<version>3.0.M4</version>

I was also facing the same issue. This solution fixed my problem.

If you have been using Eclipse's Export WAR function, you need to explicitly add the dependency into the WAR assembly.
Your answer is here: Eclipse exporting JAR in WAR

For me, this was the solution, change the old tag and instead use the following:
xmlns:p="http://primefaces.org/ui"

Their servers must be down right now because I cannot navigate to their forums either.
They are located in Turkey, I believe so they usually go down for nightly maintenance about this time.

Try use xmlns:p="http://primefaces.org/ui"
