I'm trying to use Hibernate Validator 5.0.1 and JSF2.2 but their integration seems to be broken since mojarra version 2.2.3. I've created small app to demonstrate the issue and get exception "javax.servlet.ServletException: Expression Error: Named Object: javax.faces.Bean not found." when running it on Tomcat 7.0.42.
Does anyone else have this problem?

I was able to fix it this way:
public static final String BEANS_VALIDATION_AVAILABILITY_CACHE_KEY = "javax.faces.BEANS_VALIDATION_AVAILABLE";
#PostConstruct
private void init() {
FacesContext.getCurrentInstance().getExternalContext().getApplicationMap().remove(BEANS_VALIDATION_AVAILABILITY_CACHE_KEY);
FacesContext.getCurrentInstance().getExternalContext().getApplicationMap()
.put(BeanValidator.VALIDATOR_FACTORY_KEY, Validation.buildDefaultValidatorFactory());
}
The problem seems to occur with Mojarra 2.2.3 to 2.2.6 on servlet containers like Tomcat or Jetty as Mojarra tries to load bean validation via JNDI.
I discussed this with Ed Burns at JavaLand 2014 and this issue should be fixed with Mojarra 2.2.7 (see JAVASERVERFACES-3183).
This is does work with Mojara 2.2.2 but doesn't with newer versions. Thanks to Michail for the hint. Here is another way to preconfigure Faces:
public class FacesContextBootstrap implements ServletContextListener
{
public static final String BEANS_VALIDATION_AVAILABILITY_CACHE_KEY = "javax.faces.BEANS_VALIDATION_AVAILABLE";
#Override
public void contextInitialized(ServletContextEvent sce) {
FacesContext.getCurrentInstance().getExternalContext().getApplicationMap().remove(BEANS_VALIDATION_AVAILABILITY_CACHE_KEY);
FacesContext.getCurrentInstance().getExternalContext().getApplicationMap()
.put(BeanValidator.VALIDATOR_FACTORY_KEY, Validation.buildDefaultValidatorFactory());
}
#Override
public void contextDestroyed(ServletContextEvent sce) {
}
}
Check the following:
ApplicationFactory applicationFactory = (ApplicationFactory) FactoryFinder.getFactory(FactoryFinder.APPLICATION_FACTORY);
applicationFactory.getApplication().addDefaultValidatorId(BeanValidator.VALIDATOR_ID);
applicationFactory.getApplication().addValidator(BeanValidator.VALIDATOR_ID, BeanValidator.class.getName());

I am trying to follow a very basic JSF tutorial but I am getting a null pointer in my second page (test.xhtml) if I try to read the user name there but can not find out what I am doing wrong here.
That is my bean:
import java.io.Serializable;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.SessionScoped;
#ManagedBean
#SessionScoped
public class User implements Serializable {
private static final long serialVersionUID = 1L;
private String name;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
This is my starting facelet:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:h="http://java.sun.com/jsf/html">
<h:head></h:head>
<body>
<h:form>
<h:inputText value="#{user.name}" />
<h:commandLink action="test" value="go" />
</h:form>
</body>
</html>
And I want to print the name in this facelet:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:f="http://java.sun.com/jsf/core"

<h:head></h:head>
<body>
<h:form>
<h:outputText value="#{user.name}" />
</h:form>
</body>
</html>
Whats the error here?

It seams, the problem was that the bean was in no package (or default package). Moving it to an actual package resolved the problem.

And this warning:
Typee value of the field User.greeting is not used
But there 2 strings to with same get and set but no warnings for them.
I use tomcat 7.0.54.
There's quite a bit wrong with your current code:
You're using the wrong JSF annotations
You're not using JSF-standard tags. Use:
<h:head/> instead of <head> (this is required for most ajax functionality in jsf. Without it, the necessary javascript to support ajax cannot be included on the page
<h:body> instead of <body>
An HTTP-500 is indicative of an actual bug in your code.
Don't be afraid of 500 error code. just read stack trace carefully. there were some error in your code like Null Pointer Exception. please check this code ans tell the result.
import java.io.Serializable;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.SessionScoped;
#ManagedBean
#SessionScoped
public class User implements Serializable {
private String name;
private String password;
private String greeting;
/**
* #return
*/
public String getGreeting() {
if (name == null ||name.length() == 0)
return "";
else
return "Welcome to JSF2 + Ajax, " + name + "!";
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public void setGreeting(String greeting) {
this.greeting = greeting;
}
}
also please be careful about #kolossus answer and use standard jsf tags and annotations
Try to use different annotation
import javax.faces.bean.ManagedBean;
instead of Java EE 6's
import javax.annotation.ManagedBean;

javax.el.PropertyNotFoundException: Target Unreachable, identifier 'indexMB' resolved to null
I followed the recommendations of the topic JSF2 form submit " Target Unreachable, identifier 'myModel' resolved to null ONLY on submit but did not help me.
Any help will be very useful.

Your bean is really not a CDI bean I guess your problem is caused by mixing up the imports. So try
#javax.inject.Named //defaults to "indexMB"
#javax.enteprise.context.RequestScoped
public class IndexMB {
//rest of your class here
}
I'm trying to use PrimeFaces <p:fileUpload>. I have it setup, very much the same as the showcase example, but it does not work. I never get the successful message. I get no errors or anything.
Here's my web.xml:

out.flush();
out.close();
System.out.println("New file created!");

What have I missed out?

The exception is self-explaining.
javax.el.MethodNotFoundException: /index.xhtml #15,63 fileUploadListener="#{fileUploadController.handleFileUpload(event)}": Method handleFileUpload not found
This method does indeed not exist. It's instead this one:
public void upload(FileUploadEvent event) {
Use either #{fileUploadController.upload} or rename the method to handleFileUpload.
Since yesterday I struggle with uploading a file in my jsf web application. The tutorials (one from balusC, the other one from some offical java-tutorial page) I found were very good, but somehow it still won't run. I guess there's something wrong with the web.xml, because that were the answers I found on google, but still no good results for me.
Now in details:
Firstly: I build a new project just to test the upload, so if there are too many libraries (if there is s.th. like that), pls let me know.
Secondly: it's a course projekt at my university, so there are some things, I have to use, like the h2-database and the glassfish application server.
libraries I use:
commons-el-1.0.jar
commons-fileupload.1.2.1.jar
commons-io-1.3.2.jar
commons-logging.1.1.1.jar
tomahawk20-1.1.10.jar
h2-1.2.141.jar
jboss-el-2.0.1.GA.jar

Like I said, it's just the tutorial I put together; the name of the file is shown in the textfield, but when hitting submit, there's just the exception.
Thanks in advance.
EDIT: I just thought it might be useful to know that work with the 1.6.0jdk.
I had the same problem, but worked in linux and fail in windows. To pass over this issue i found this solution:
Do not forget to add the "enctype" attribute to your Form and set this attribute to "multipart/form-data".
<h:form enctype="multipart/form-data">
