I'm initiating in java jsf, I created an xhtml simple to show table in localhost but I am receiving this error "This XML file does not appear to have any style information associated with it. The document tree is shown below." I don't have any idea of to solve this. My project is very simple is only to display a jsf table with records of mysql table. Below is my project.
Especialidade:
package itc.itcsystems.beans;
public class Especialidade
{
private int ID;
private String Especialidade;
public Especialidade()
{
}
public Especialidade(int ID, String Especialidade)
{
this.ID = ID;
this.Especialidade = Especialidade;
}
public int getID() {
return ID;
}
public void setID(int ID) {
this.ID = ID;
}
public String getEspecialidade() {
return Especialidade;
}
public void setEspecialidade(String Especialidade) {
this.Especialidade = Especialidade;
}
}
