Basically , in the input.xhtml there is a form which takes a username and password and if they are equal to a specific value(doesn't matter the value) the program should print a message in the browser, but this doesn't happen. To make sure of the problem i added 2 lines of "System.out.println(...)" where i print the value of the property and what i found out is that the properties are still null even after i submit. So after i click send in the console is written "null null". Any help is appreciated!
This is the UserBean class (backing bean)
package bean;
import java.io.Serializable;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.SessionScoped;
@ManagedBean
@SessionScoped
public class UserBean implements Serializable{
/**
*
*/
private static final long serialVersionUID = 1L;
private String name;
private String password;
private String output_message;
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 String go(){
output_message = "";
if(name == null && password == null){
output_message += "Both fields cannot be empty!";
}else if(name == "name" && password == "pass"){
output_message += "Success!";
}else{
output_message += "Data is wrong!";
}
System.out.println(name);
System.out.println(password);
return output_message;
}
public String getOutput_message() {
return output_message;
}
public void setOutput_message(String output_message) {
this.output_message = output_message;
}
public String ret(String r){
return r;
}
}
This is the input.xhtml file, that contains the form that will submit the data to the bean. (Ignore the url to template.xhtml, it's just a parent template that has a header and a footer other than the mid-content that input.xhtml defines)

I just solved this. the problem was with the input tag, the value attribute does not represent the value written in the textbox is just some kind of a default value or somekind of a pre-value. Anyway instead of input and form tags i used and which worked out fine h is a namespace with url xmlns:h="http://xmlns.jcp.org/jsf/html"
