H2O error when calling as.factor on H2O data frame - r

When I call the following reproducible doce:
install.packages("h2o", type = "source", repos =
"http://h2o-release.s3.amazonaws.com/h2o/rel-ueno/8/R")
library(rsparkling)

sc <- spark_connect(master = "local", config = conf, version = "2.0.2")
h2o_context(sc ,strict_version_check = T)
h2o.init(nthreads = -1)
NFLPlayers <- c('Von Miller','Christian McCaffrey','Joe Thomas')
salary <- c(21000, 23400, 26800)
Valuable = c(1,1,1)
Rdata <- data.frame(NFLPlayers, salary, Valuable)
system.time(Test <- copy_to(sc, Rdata, "Rdata"))
Test1 = as_h2o_frame(sc, Test, strict_version_check = FALSE)
Test1$Valuable<-as.factor(Test1$Valuable)
On an H2O dataframe I get the following error.
ERROR: Unexpected HTTP Status code: 500 Server Error (url = http://127.0.0.1:54321/99/Rapids)
Error: lexical error: invalid char in json text.

(right here) ------^
This is brand new and it is not only happening in my computer but also on that of a colleague. I have restarted the cluster. Reinstalled sparklyr and Rsparkling. I have also changed versions and am constantly getting the same error. Any ideas?
Some of the logs:

This was a bug and is fixed in latest Sparkling Water versions for Spark 2.0, Spark 2.1 and Spark 2.2

Can't open a diferent window than default on JavaFX

The error log says that the function can't find the file ("Location is required"), and as far as I know, the fxml file name is right because it is in the same package as the main. I really don't know what to do because it works just fine with the sample fxml file created with the project.
package clfx;
import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.stage.Stage;
public class CLFX extends Application {
#Override
public void start(Stage stage) throws Exception {
Parent root = FXMLLoader.load(getClass().getResource("MenuPrincipal.fxml"));
Scene scene = new Scene(root);
stage.setScene(scene);
stage.show();
}
public static void main(String[] args) {
launch(args);
}
}
And the error log:

Problems with FXMLLoader in javaFX tutorials from Oracle

Some time ago I started javafx tutorials from Oracle website. During doing this tutorial https://docs.oracle.com/javase/8/javafx/get-started-tutorial/fxml_tutorial.htm I encountered a problem. Here is a code:
1) fxml_example.fxml
<?xml version="1.0" encoding="UTF-8"?>
<?import java.net.*?>
<?import javafx.geometry.*?>
<?import javafx.scene.control.*?>
<?import javafx.scene.layout.*?>
<?import javafx.scene.text.*?>
<GridPane fx:controller="fxmlexample.FXMLExampleController"
xmlns:fx="http://javafx.com/fxml" alignment="center" hgap="10" vgap="10">
<fx:script>
function handleSubmitButtonAction(){
actiontarget.setText("Calling the JavaScript");
}
</fx:script>
<padding>
<Insets top="25" right="25" bottom="10" left="25" />
</padding>
<Text text="Welcome" GridPane.columnIndex="0"
GridPane.columnSpan="2" GridPane.rowIndex="0" />
<Label text="User Name:" GridPane.columnIndex="0"
GridPane.rowIndex="1" />
<TextField GridPane.columnIndex="1" GridPane.rowIndex="1" />
<Label text="Password:" GridPane.columnIndex="0"
GridPane.rowIndex="2" />
<PasswordField fx:id="passwordField"
GridPane.columnIndex="1" GridPane.rowIndex="2" />
<HBox alignment="bottom_right" spacing="10"
GridPane.columnIndex="1" GridPane.rowIndex="4">
<Button text="Button" onAction="#handleSubmitButtonAction" />
</HBox>
<Text fx:id="actiontarget" GridPane.columnIndex="0"
GridPane.columnSpan="2" GridPane.halignment="RIGHT"
GridPane.rowIndex="6" />
</GridPane>
2) FXMLExample.java
package application;
import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.stage.Stage;
public class FXMLExample extends Application{
#Override
public void start(Stage stage) throws Exception {
Parent root = FXMLLoader.load(getClass().getResource("fxml_example.fxml"));
Scene scene = new Scene(root, 300, 275);
stage.setTitle("FXML Welcome");
stage.setScene(scene);
stage.show();
}
public static void main(String[] args){
launch(args);
}
}
3) FXMLExampleController.java
package application;
import javafx.event.ActionEvent;
import javafx.fxml.FXML;
import javafx.scene.text.Text;
public class FXMLExampleController {
#FXML private Text actiontarget;
#FXML protected void handleSubmitButtonAction(ActionEvent event) {
actiontarget.setText("Sign in button pressed");
}
}

Exception running application application.FXMLExample
So, is something wrong with FXMLLoader? But what? And how to fix it?

Your FXML sets the fx:controller to fxmlexample.FXMLExampleController, yet your package name is application, so the fx:controller value should be application.FXMLExampleController (or you could change your package name to fxmlexample to match the example code).

NullPointerException when trying to execute DAO... Could not initialize class ..JavaReflectionManager

I am getting a NullPointerException when I try to execute the checkCredentials function in my LoginController. I think the problem is not with my Service Implementation but with DAO Implementation. But I am not able to find what causes the issue. I am not sure if the problem is with the
#Autowired
private LoginDAO loginDAO;
or the
#Repository("loginDAO")
When I submit the login credentials I get the following

I really dont understand what is wrong with my code.
I now have the solution, which is decribed in the below answer. The second problem was actually related to dependencies.

I found the solution to the second issue (first which was solved Thanks to #JBNizet)
It was actually regarding the dependencies added in the pom.xml, which I havnt included here. What I did is I actually upgraded my hibernate version to 5.1.0 and then added hibernate-commons-annotations 5.0.1.Final. So my dependencies are now like below.
The specific, Hibernate core will have hibernate-common-annotation and this has the missing class

public void setPupilRepositories(PupilRepositories pupilRepositories) {
this.pupilRepositories = pupilRepositories;
}
...
}
PupilRepositories
package repositories;
import entities.Pupil;
import org.springframework.data.repository.CrudRepository;
public interface PupilRepositories extends CrudRepository<Pupil, Long> {
long count();
}
PupilDAOImpl class
#Repository
public class PupilDAOImpl implements PupilDAO {
private static SessionFactory sessionFactory = new Configuration().configure().buildSessionFactory();
public static Session getCurrentSession(){
Session session = sessionFactory.openSession();
session.beginTransaction();
return session;
}
public static void closeCurrentSession(Session session){
session.getTransaction().commit();
session.close();
}
/**
* Get all pupils
* #return all pupils from database
* */
public List<Pupil> getAllPupils() {
Session session = getCurrentSession();
List<Pupil> pupilList = session.createCriteria(Pupil.class).list();
closeCurrentSession(session);
return pupilList;
}

Make sure you have below dependency in your classpath:
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-entitymanager</artifactId>
<version>3.3.2.GA</version>
</dependency>
Finally after lot of refactoring got a working code with Connection Refuse to Database, which you can fork from GitHub.
Hope it helps :)

this is AlertFacade:
#Stateless public class AlertFacade extends AbstractFacade {
#PersistenceContext(unitName = "flams_pu")
private EntityManager em;
#Override
protected EntityManager getEntityManager() {
return em;
}
public AlertFacade() {
super(Alert.class);
} }
which i use in a JSF Managed bean.
is the EJB supposed to be Serializable ? I don't get it.
Please help

I would try and add to the class signature implements Serializable. Since it's a marker interface, you don't have to implement any method.
