JSF Target unreachable identifier resolved to null [duplicate]

Answer 1

I want to share my experience with this Exception. My JSF 2.2 application worked fine with WildFly 8.0, but one time, when I started server, i got this "Target Unreacheable" exception. Actually, there was no problem with JSF annotations or tags.

Only thing I had to do was cleaning the project. After this operation, my app is working fine again.

I hope this will help someone!

The problem seems related to the double configuration of your managed bean with the same name:

• Annotation configuration by using @ManagedBean and @SessionScoped annotations on the class called user.
• XML configuration in faces-config.xml file through the <managed-bean> node called User.

You should have a single configuration per managed bean i.e. the name. In this case, since you basically have the same managed bean configured twice, just remove one of the configurations. I recommend removing the XML configuration since the annotation configuration is more readable and understandable.
