I’m starting to create a web application using JSF, but I try to insert some data through a form and it displays the error below:
/usuario.xhtml @19,72 value="#{usuarioBean.email}": Target Unreachable, Identifier 'usuarioBean' resolved to null
My save method:
public String salvar(){
FacesContext context = FacesContext.getCurrentInstance();
if(!this.senha.equalsIgnoreCase(this.confirmaSenha)){
context.addMessage(null,new FacesMessage(FacesMessage.SEVERITY_ERROR,"Senha confirmada incorretamente",""));
return "usuario";
}
//salva usuario
return "sucesso";
}

Uses CDI bean, JSF bean ? created get/set for properties ? leverages and puts all manageBean.

Dilnei, use JSF bean
– Felipe Januário
Use Maven? or add libs to the app’s classpath? can you add the information? @Request Scope comes from this import?
import javax.faces.bean.RequestScoped;
– Dilnei Cunha
Dilnei, I don’t use Maven. I added libs to the classpath. I added lib img to the question. ’s annotation comes from this import: import javax.faces.bean.Requestscoped;

Worse than I’m not even able to debug, to check if he’s getting into the method. I’m a beginner, and I’m developing this application through an example from the book.

Sorry so many questions but if necessary, you have configured web.xml? and created the faces, faces-config.xml configuration file?
