404 NullPointerException with AngularJs Java and Jersey - mysql

I've been asked to make an App with AngularJs, Bootstrap, Java and Tomcat as a server. I'm new with java ee so maybe my error is quite simple, but I can't find a solution.
So when I start the project I see my angular app, but when i press a button and it calls http://localhost:8080/MissingDogPoc/res/dog I get this error:
Http Status 500:

SOLUTION
First if you have a web.xml in your WEB-INF you don't need it as long as you have an "ApplicatiationConfig.java" (This is auto-generated if you follow the netbeans tutorials that are out there)
The code will be like this:
package com.gabriel.missingdogpoc.service;
import java.util.Set;
import javax.ws.rs.ApplicationPath;
import javax.ws.rs.core.Application;
#ApplicationPath("api")
public class ApplicationConfig extends Application {
#Override
public Set<Class<?>> getClasses() {
Set<Class<?>> resources = new java.util.HashSet<>();
addRestResourceClasses(resources);
return resources;
}
private void addRestResourceClasses(Set<Class<?>> resources) {
resources.add(com.gabriel.missingdogpoc.service.DogFacadeREST.class);
}
}
Then since Tomcat its a "Web-Server" and not an "Application Server" we need to manage the entities ourselves! So we have to make our Entity manager:
LocalEntityManagerFactory.java
package com.gabriel.missingdogpoc.util;
import javax.persistence.EntityManager;
import javax.persistence.EntityManagerFactory;
import javax.persistence.Persistence;
import javax.servlet.ServletContextEvent;
import javax.servlet.ServletContextListener;
import javax.servlet.annotation.WebListener;
#WebListener
public class LocalEntityManagerFactory implements ServletContextListener{
private static EntityManagerFactory emf;
#Override
public void contextInitialized(ServletContextEvent event) {
emf = Persistence.createEntityManagerFactory("com.gabriel_MissingDogPoc_war_1.0-SNAPSHOTPU");
}
#Override
public void contextDestroyed(ServletContextEvent event) {
emf.close();
}
public static EntityManager createEntityManager() {
if (emf == null) {
throw new IllegalStateException("Context is not initialized yet.");
}
return emf.createEntityManager();
}
}
And now since we have our own entity manager we need to use it in our rest service. You will probably have "Abrstract Facade" if you generated it with netbeans, and you will have to replace:
protected abstract EntityManager getEntityManager();
public void create(T entity) {
getEntityManager().getTransaction().begin();
getEntityManager().persist(entity);
getEntityManager().getTransaction().commit();
}
public List<T> findAll() {
getEntityManager().getTransaction().begin();
javax.persistence.criteria.CriteriaQuery cq = getEntityManager().getCriteriaBuilder().createQuery();
cq.select(cq.from(entityClass));
List<T> res= getEntityManager().createQuery(cq).getResultList();
getEntityManager().getTransaction().commit();
return res;
}
If you have any problems with the backend you can check my code in github /Gaabooo/MissingDogPoc/

Your problem is that you're using Tomcat, which is an implementation of the Servlet and JSP specifications.
You've tried to turn it into a JavaEE 7 web container by adding Jersey and EclipseLink to it. Unfortunately it will still be missing the integration between the components. In your case, Jersey has no idea that it needs to inject an EntityManager into your DogFacadeREST object, so you get a NullPointerException as soon as you try to call it. Additionally, the #Stateless annotation will be completely ignored because you need to include EJB support as well for this.
It's way easier to use something like WildFly, TomEE or GlassFish and then you can throw away all those dependencies (except for the javaee-web-api).

I get problem when I run Junit on my test, browser is not opening

I am new in Selenium and I have problem with Junit.
Problem is browser is not starting when I use Junit annotations, if I write the same test case without Junit, it runs with no problem. I have also tried with TestNG and I get the same problem
import org.junit.After;
import org.junit.Before;
import org.junit.Test;

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
public class Smoke {
public WebDriver driver = new ChromeDriver();
#Before
public void testSetUp() {
System.setProperty("webdriver.chrome.driver", "./Driver/chromedriver.exe");
driver.get("url");
driver.findElement(By.xpath("/html/body/p/a")).click();
}
#Test
public void aboutPage() {
driver.findElement(By.xpath("//*[#id=\"menu-item-137\"]/a")).click();
}

public void productsPage() {
driver.findElement(By.xpath("//*[#id=\"menu-item-17\"]/a")).click();
}
#After
public void testTearDown()

I get this in console:

I need help using Jsoup to display the html from a website

very new to coding, using Java writing android application. I have included my code to this point below. At this point I am just trying to get the HTML from a website. I have been googling my way to this point. I do have <uses-permission android:name="android.permission.INTERNET" />in the manifest. I call the code to get the html in the oncreate event (new URLParser). At first I tried to view the html in the logcat, the code is still there for that in the onPostExecute event. The program ran fine this way, but the html did not show up in the verbose section of the logcat. So I added a temporary button and text view to the application. The button's onClick is set to call "showHTML". The app loads up, and when I press the button it crashes. So I cannot seem to see the html in the logcat, or the textview after pressing the button.
package com.example.brewerycruiser;
import androidx.appcompat.app.AppCompatActivity;
import android.os.AsyncTask;
import android.os.Bundle;
import org.jsoup.Jsoup;
import org.jsoup.nodes.Document;
import java.io.IOException;
import android.util.Log;
import android.view.View;
import android.widget.TextView;
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
new URLParser();
}
public void showHTML (View view) {
TextView HTMLview =
view.getRootView().findViewById(R.id.textView);
HTMLview.setText(doc.toString());
}
Document doc = null;
public class URLParser extends AsyncTask<String, Void, String> {
#Override
protected String doInBackground(String... params) {
try {
doc = Jsoup.connect("https://www.coloradobrewerylist.com/brewery/").userAgent("Mozilla/5.0").get();
} catch (IOException ex) {
ex.printStackTrace();
}
return null;
}
protected void onPostExecute(Void result) {
Log.v("DATA", doc.toString());
}
}
}
The error log is below:

"java.lang.NullPointerException" when trying to click any element in a page

The code was running completely fine until yesterday. Now, when I am trying to run any test case, Selenium (using Java) throws java.lang.NullPointerException on the homepage itself. Below is a simple test case which is failing due to the error.

Kindly suggest.
WebEventListener.java:31: keep the null check, one of the elements you are using is throwing a null pointer exception.
If you can post the printed content of the WebEventListener.java on line 31, then we can better examine the problem. To do that, change this line:
public void afterFindBy(By arg0, WebElement arg1, WebDriver arg2) {
System.out.println("Find happened on " + arg1 + " Using method " + arg0);
}
As per you comment " When the control goes into homepage.clickSearchLink() method, the test ends and error comes."
check whether this method "homepage.clickSearchLink()" is returning searchpage instance.
the method should be
~public Searchpage clickSearchLink(){
//click on element to get search page
//Also check whether element is present on page or not.
return new Searchpage();
}~

Junit Test Case

I wanted to write junit for below method "createEmailTripEvent()", So i was trying to mock EmailTrip interface by using EasyMock but couldn't able to proceed.
Is it possible to use EasyMock for mocking interface or we need to go for Mockito only ?
If Mockito is the only option, then anybody can explain me how we can use ?
Please refer below class & Interface
private EmailTrip emailTrip;
public ModelAndView createEmailTripEvent (HttpServletRequest request,
HttpServletResponse response) throws Exception {
emailTrip.createEmailTripEvent(Code, emailRequest);
//Need to write junit for above method
}
public interface EmailTrip {
void createEmailTripEvent(String code, TripEmailRequest request)
throws Exception;
}
public class EmailTripImpl implements EmailTrip { }
You should include the following dependency to your maven pom (if not using maven, urgently consider doing so...). Otherwise include the EasyMock dependency to your class path.
<dependency>
<groupId>org.easymock</groupId>
<artifactId>easymock</artifactId>
<version>3.3.1</version>
<scope>test</scope>
</dependency>
After that you should be able to create your test class.
import static org.easymock.EasyMock.*;
import org.easymock.*;
import org.junit.Rule;
import org.junit.Test;
public class MyTinyTest extends EasyMockSupport {
#Rule
public EasyMockRule rule = new EasyMockRule(this);
#Mock
private EmailTrip emailTrip;
#TestSubject
private final ServletClass servlet = new ServletClass(emailTrip);
#Test
public void testCreateEmailTripEvent() {
// you should know how to create an email request instance!
EmailTripRequest emailRequest = createRequest();
// tell EasyMock what behavior is expected...
emailTrip.createEmailTripEvent("code", emailRequest);
// start testing...
replayAll();
// excute method to test...
ModelAndView result = servlet.createEmailTripEvent(servletRequest, servletResponse);
// verify if expected behavior occured.
verifyAll();
// check other assertions concerning the method result...
}
}

Can Anyone please guide me? What am I doing wrong? Why is my repository being null?
The endpoint does work, when Ii use Curl command and test, however, I'm unable to write a junit for unit testing, Please help
I meet exactly same problem.
When I run the project, it works fine.
But when I test controller some autowired variable becomes null, which failed the test.
In my code, I have a userWebController which does "signup" job. There is another class CustomedUserDetailsService which work with a JdbcTemplate object to add a new user to database. the JdbcTemplate object is autowired with a bean. When I test the controller, this JdbcTemplate object is null which means it is not injected successful.
I tried this following method(the jdbc bean is defined in class OnlineDBConfig), but does not work:
#ContextConfiguration( classes = {OnlineDBConfig.class})
I solve my problem with following solution:
1, move the failed_autowired object to the Test class (StandaloneUserControllerTest) directly.
2, pass the object to the controller class which use it.
Following is the final test class:
public class StandaloneUserControllerTest extends AbstractSpringJunit4Tests {
#Autowired
#Qualifier("jdbcOnline")
protected JdbcTemplate jdbc;
#Before
public void before(){
RestAssuredMockMvc.standaloneSetup(new UserWebController(jdbc) ) ;
if( jdbc == null )
fail("autowired failed again") ;
}
}
It is terrible, but it works.
Hope there will be better solution.
