JSF 1.2 not working at all inside JSP pages

 原文  2017-03-21 13:59:46  6   1    java/ spring/ jsp/ jsf/ spring-boot

Question

I'm working on an old project trying to get it back to working state with Jetty, Spring & Spring Boot, and it uses JSF 1.2 on which i'm not really familiar with. It also has ibm taglib libraries that I was suppose to get rid of, but I thought the problem was part of me missing the libraries so for the time being I added them to the project.

I'm having and major issue where as I fill the user credentials (login & password) to the page, the controller receives them as null values for some reason. It feels like actually all the #{} inside my login page are not registered to the JSF.

The exact error is

javax.faces.FacesException: # {aaController.login}: java.lang.NullPointerException

For the dependency part I have jsf-api, jsf-impl, jsf-ibm, odc-jsf for the jsf-libaries.

My web.xml looks like this :

My Controller looks like this: 

public class AaController extends BaseController {
public static final int ROLE_INTERNAL = 1;
public static final int ROLE_EXTERNAL = 2;

private loginView loginView = new loginView();
private int role;

public String login() throws OrgHallintaException {
    String result = null;
    AaFasadi aaFasadi = new AaFasadi();
    log.info("Loggin in");


    if (aaFasadi.login(loginView.getLogin(), loginView.getPassword())) {

        if (aaFasadi.getEnviroment().trim().equals("PRODUCTION")) {
            loginView.setEnviroment("        ");
        } else {
            loginView.setEnviroment(aaFasadi.getEnviroment());
        }
        result = "ok";

    } else {
        result = "error";
    }

    return result;
}

public String logout() {
    AaFasadi aaFasadi = new AaFasadi();
    aaFasadi.logout();
    return "ok";
}

public loginView getloginView() {
    return loginView;
}

public Kayttaja getUser() {
    return AaFasadi.getUser();
}

}

And the Class that Controller calls looks like this 

public class AaFasadi {

private String enviroment="";

private static final String USER_SESSION_KEY = "orgmanager.User";

public static User getUser() {
    ServletRequest req = (ServletRequest) FacesContext.getCurrentInstance().getExternalContext().getRequest();                     
    return getUser(req);
}

public static User getUser(ServletRequest req) {        
    HttpServletRequest request = (HttpServletRequest) req;

    User user = (User) request.getSession(true).getAttribute(USER_SESSION_KEY);

    return user;

}

public boolean login(String LoginName, String password) throws OrgHallintaException {

    User user = null;

    try {           
            PersonelLoginTask personelLoginTask = new PersonelLoginTask();
            PersonelLoginView personelLoginView = toimihenkiloSisaankirjausTehtava.execute(LoginName.toUpperCase(), password);

        if (personelLoginView != null) {
            if (personelLoginView.getEnviroment().trim().equals("PRODUCTION"))
                personelLoginView.setEnviroment("        ");
            User = new DefaultUserImpl(personelLoginView);
            Enviroment = personelLoginView.getEnviroment();
            }

    } catch (TehtavanHallintaException e) {
        System.out.println("User " + Usertunnus + " Login failed " + e);
    }


    if (User != null) {

        ServletRequest req = (ServletRequest) FacesContext.getCurrentInstance().getExternalContext().getRequest();                     
        HttpServletRequest request = (HttpServletRequest) req;        
        request.getSession(true).setAttribute(User_SESSION_KEY, User);

        return true;
    } else {
        return false;
    }
}

public void logout() {
    ServletRequest req = (ServletRequest) FacesContext.getCurrentInstance().getExternalContext().getRequest();                     
    HttpServletRequest request = (HttpServletRequest) req;        
    request.getSession(true).removeAttribute(User_SESSION_KEY);
    request.getSession().invalidate();               
}



public String getEnviroment() {
    return enviroment;
}

public void setEnviroment(String ymparisto) {
    this.enviroment = enviroment;
}

}

For some reason my Login.jsp pages aaController.loginView.login & aaController.loginView.password don't work at all and they are returning null values and i don't know why. the loginView has proper Get and Set methods in it's class. Is there something wrong with my JSF configuration?

My loginview looks like this 

public class loginView extends BaseView {

private String login;
private String password;
private String Enviroment;
private Date date = new Date(System.currentTimeMillis());




public String getlogin() {
    return login;
}
public void setlogin(String login) {
    this.login = login;
}
public String getpassword() {
    return password;
}
public void setpassword(String password) {
    this.password = password;
}

public String getEnviroment() {
    return Enviroment;
}

public void setEnviroment(String Enviroment) {
    this.Enviroment = Enviroment;
}


public void setDate(Date date) {
    this.date = date;
}

}

Ok the answer was quite silly, but I finally found it out. I was using the web.xml schema version 2.4, but It needed 2.5 to work.
