How to implement proxy pattern?

I'm trying to understand how to make and use a proxy design pattern. I have no idea what am i doing wrong. Any suggestions would be appreciated:
Load method should simulate downloading configuration from remote server... and it kinda does. The 2 seconds delay should be launched just once, and then it should go smoothly.
public interface ConfigLoader {
String load();
}
RealObject
import lombok.Getter;
import lombok.Setter;
import org.apache.commons.lang3.RandomStringUtils;
import pl.sdacademy.prog.streams.MyExepction;
#Getter
#Setter
public class ConfigLoaderImplementation implements ConfigLoader {
private String configuration;
private String serverUrl;
public ConfigLoaderImplementation(final String serverUrl) {
this.serverUrl = serverUrl;
}
#Override
public String load() {
try {
Thread.sleep(3000);
} catch (InterruptedException e) {
throw new MyException("Sleeping canceled!", e);
}
System.out.println("Configuration from " + getServerUrl() + " downloaded successfully");
String generatedConfiguration = RandomStringUtils.randomAlphabetic(10);
setConfiguration(generatedConfiguration);
return generatedConfiguration;
}
}
Proxy
import lombok.Data;
#Data
public class ConfigLoaderProxy implements ConfigLoader {
private ConfigLoader proxy;
public ConfigLoaderProxy(String url) {
this.proxy = proxy;
}
#Override
public String load() {
if (proxy == null) {
proxy = new ConfigLoaderImplementation("www.blablA.com");
return proxy.load();
} else {
return proxy.load();
}
//todo
}
}
Test class, with main
public class ConfigLoaderDemo {
public static void main(String[] args) {
ConfigLoader proxy = new ConfigLoaderProxy("sdasd");
proxy.load();
proxy.load();
proxy.load();
}
}

public class ConfigLoaderProxy implements ConfigLoader {
private final ConfigLoader configLoader;
private String configuration;
public ConfigLoaderProxy(final ConfigLoader configLoader) {
this.configLoader = configLoader;
}
#Override
public String load() {
if (configuration == null) {
configuration = configLoader.load();
}
return configuration;
}
}

A NullPointerException is caught when I try to add a new client in a CRUD Spring boot Application

I am doing a CRUD web application using Spring boot, spring mvc and Spring Data JPA. I wanted to test my code in the main class with adding a new client. It returns me a NullPointerException. I already check my code with a debug mode. Honestly I don't see where is exactly the issue, so, if it's possible to help it will be a pleasure.
Entity class :
#Entity
#Table(name="cliente")
public class Cliente implements Serializable{
#Id #GeneratedValue
private Integer idCliente;
private String iceCliente;

System.out.println(clienteService);
}
Stacktrace :
Stacktrace

First, for your test scenario, it's better to use ApplicationRunner.
NestideasFacturasApplication must implement ApplicationRunner, and override run method. Then you can write your test scenario in run.
Code :
#SpringBootApplication
public class NestideasFacturasApplication implements ApplicationRunner {
public static void main(String[] args) {
SpringApplication.run(NestideasFacturasApplication.class, args);
}
#Override
public void run(ApplicationArguments args) {
//Your test scenario ...
}
}
Second, Change injection of ClienteService like below
#Autowired
private ClienteService clienteService;
So we have (Entire code)
#SpringBootApplication
public class NestideasFacturasApplication implements ApplicationRunner {
#Autowired
private ClienteService clienteService;
public static void main(String[] args) {
SpringApplication.run(NestideasFacturasApplication.class, args);
}
#Override
public void run(ApplicationArguments args) {
//Your test scenario
System.out.println("Application démarrée");
System.out.println(clienteService);
clienteService.agregarCliente(new Cliente("16565465", "Hassan", "JROUNDI", "Said Hajji", "0662165537", "hassan.jroundi#outlook.fr", TipoCliente.EMPREZA, "Salé"));
}
}

All JPA queries fail to find any result(even tho data is present in the MySQL DB)

I'm trying to set up javax.Persistence in my project, and I've started to use the basic approach:
EntityManagerGenerator
package olsa.amex.dao;
import javax.persistence.*;
public class EntityManagerGenerator {
private EntityManager currentSession;
private EntityTransaction currentTransaction;
public EntityManager openCurrentSession() {
if ((currentSession == null)||(currentSession != null && !currentSession.isOpen()))
currentSession = getSessionFactory().createEntityManager();
return currentSession;
}
public EntityManager openCurrentSessionwithTransaction() {
if ((currentSession == null)||(currentSession != null && !currentSession.isOpen()))
currentSession = getSessionFactory().createEntityManager();
currentTransaction = currentSession.getTransaction();
currentTransaction.begin();
return currentSession;
}
public void closeCurrentSession() {
if (currentSession != null && currentSession.isOpen())
currentSession.close();
}
public void closeCurrentSessionwithTransaction() {
if (currentSession != null && currentSession.isOpen()) {
currentTransaction.commit();
currentSession.close();
}
}
private static EntityManagerFactory getSessionFactory() {
EntityManagerFactory entityManager = Persistence.createEntityManagerFactory("JPAAmex");
return entityManager;
}
public EntityManager getCurrentSession() {
return currentSession;
}
public void setCurrentSession(EntityManager currentSession) {
this.currentSession = currentSession;
}
public EntityTransaction getCurrentTransaction() {
return currentTransaction;
}
public void setCurrentTransaction(EntityTransaction currentTransaction) {
this.currentTransaction = currentTransaction;
}
}

And here's the code I used to test out everything:
try {
logger.info("Hibernate test");
ViewAgentSsbService service = new ViewAgentSsbService();
List<ViewAgentssb> entities = service.findAll();
logger.info(entities.toString());
} catch (Exception e1) {
logger.info("Failed... " + e1.getMessage());
ErrorUtility.getError(e1);
}
And the query successfully starts, but it always returns an empty list, even tho there is data present in the MySQL DB.
EDIT: I know I can use the Repositories, but for now I just want to check if everything works as it should.

I found the problem, apparently it was all caused by the wrong jdbc connection string.
In order to generate the entities I used the following string:
jdbc:mysql://rmarjboss-001c.customer.olsa:3306/amex_digital_sbs_dev?useUnicode=yes&characterEncoding=UTF-8
What I used in my persistence.xml is this:
jdbc:mysql://rmarjboss-001c.customer.olsa:3306/amex_digital_sbs_dev
In order for everything to work correctly, I had to set the correct string in my persistence.xml:
jdbc:mysql://rmarjboss-001c.customer.olsa:3306/amex_digital_sbs_dev?useUnicode=yes&characterEncoding=UTF-8

cannot fetch the exact dto returned from ejb to liferay controller

I am doing a liferay project which use ejb at back end. so my ejb method looks like this:-
#Override
public List<RmisPaymentDetailsDto> getEpaymentDetails(String ebpCode) {
Query q = entityManager.createQuery("select s from EpaymentBo s where s.ebpCode=:ebpcode")
.setParameter("ebpcode",ebpCode);
#SuppressWarnings("unchecked")
List<ProductBo> list = q.getResultList();
Iterator<ProductBo> i = list.iterator();
List<RmisPaymentDetailsDto> rList = new ArrayList<RmisPaymentDetailsDto>();
while(i.hasNext()){
EpaymentBo ep =(EpaymentBo) i.next();
RmisPaymentDetailsDto dto = new RmisPaymentDetailsDto();
dto.setAdvertisementcode(ep.getAdvertisementcode());
dto.setAmount(ep.getAmount());
dto.setStudentmasterid(ep.getStudentmasterid());
dto.setEbpgendate(ep.getEbp_gen_date());
dto.setEbpcode(ep.getEbpCode());
dto.setPaymentstatus(ep.getPaymentstatus());
dto.setCandidatenameinnepali(ep.getCandidatenameinnepali());
rList.add(dto);
}
return rList;
}
the above method successfully fetches data from database and sets it to my RmisPaymentDetailsDto.
like this:-
now i am calling same method from my liferay controlller.
PreExaminationRemote preRef = (PreExaminationRemote) jndiContext
.lookup("PreExamination/remote");
List<RmisPaymentDetailsDto> rDto = preRef.getEpaymentDetails(ebpCode);
I am wondering how my one property(candidatenameinnepali) is lost as i return same dto from my ejb.
My dto looks like this:-
public class RmisPaymentDetailsDto implements Serializable {
private static final long serialVersionUID = 1L;
private String advertisementcode;
private String ebpcode;
private String amount;
private String studentmasterid;
private Date ebpgendate;

Cannot resolve reference Local ejb-ref

I have an issue in programming an EJB application. I search a solution but I still have the same problem in intelliJ with Glassfish4 :
" Cannot resolve reference [Local ejb-ref name=EJB.AdminEJB,Local 3.x interface =Interface.AdminInterface,ejb-link=null,lookup=,mappedName=,jndi-name=,refType=Session] because there are [2] ejbs in the application with interface Interface.AdminInterface."
And excuse-me for my english, I'm french.

Thank's very much for any help

When you have two EJBs implementing the same interface they need to be differentiated so that the container knows which one to inject.
Add the name parameter in the #Stateless annotation to all beans implementing the same interface. In the #EJB annotation, use the beanName parameter to inject the appropriate session bean implementation.
#Stateless(name="AdminEJB1")
public class AdminEJB implements AdminInterface { .... }
#EJB(beanName = "AdminEJB1")
private AdminInterface myAdminEjb;
You can also skip the name parameter in the #Stateless annotation and then use the name of the implementing class as the beanName parameter in the #EJB annotation.
#Stateless
public class AdminEJB implements AdminInterface { .... }
#EJB(beanName = "AdminEJB")
private AdminInterface myAdminEjb;

I had same error, but I didn't work with one interface for different EJBs (generated local Session Beans from entity classes). So I am putting this answer if somebody had same problem as me, as I didn't found one here. My framework generated "ejb-local-ref" tag in pom.xml on its own. After deleting it, all works perfectly.

Another cause for this problem, although uncommon, may be the delay in communicating with the JMX port. To get around this it is possible to put the key -Dhk2.parser.timeout = 300
