i am getting
StartSensor Attempt to invoke virtual method 'void io.realm.ProxyState.setConstructionFinished()' on a null object reference
i try to create a new object with primarykey inside application class.
primarykeyFactory works it set the new key to "1" the database is empty at this moment.
public class SensorRecord extends MainApplication {
private final static String TAG = SensorRecord.class.getSimpleName();
private Realm mRealm;
public SensorRecord() {
Realm.init(this);
mRealm = getInstance(getRealmConfig());
}
public void StartSensor(long startTime) {
long newprimekey = PrimaryKeyFactory.getInstance().nextKey(SensorData.class);
try {
mRealm.beginTransaction();
SensorData mSensorData = mRealm.createObject(SensorData.class, newprimekey);
mSensorData.setstarted_at(startTime);
mRealm.commitTransaction();
mRealm.close();
} catch (Exception e) {
Log.v(TAG, "StartSensor " + e.getMessage());
}
}}
my main application class which init the realm config
public class MainApplication extends RealmBaseApplication {
private final static String TAG = MainApplication.class.getSimpleName();
Realm mRealm;
#Override
public void onCreate() {
super.onCreate();
Realm.init(this);

try {
Log.v(TAG, "Start PrimaryKeyFactory ");
PrimaryKeyFactory.getInstance().initialize(mRealm);
} catch (Exception e) {
Log.v(TAG, "initializePrimaryKeyFactory " + e.getMessage());
}
}}
and my realm config class
public abstract class RealmBaseApplication extends Application {
private RealmConfiguration realmConfiguration;
protected RealmConfiguration getRealmConfig() {
if (realmConfiguration == null) {
realmConfiguration = new RealmConfiguration
.Builder()
.deleteRealmIfMigrationNeeded()
.build();
}
Realm.setDefaultConfiguration(realmConfiguration);
return realmConfiguration;
}
protected void resetRealm() {
Realm.deleteRealm(getRealmConfig());
}}
kind regards
viktoria
ok fixed by myself. had add butterknife tonight. and with that i add apt to my build.gradle... i removed
classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8'
apply plugin: 'com.neenbedankt.android-apt'
and replaced
apt 'com.jakewharton:butterknife-compiler:8.5.1'
with
annotationProcessor 'com.jakewharton:butterknife-compiler:8.5.1'

I am new to unit test and I am trying to use robolectric to do the test for my android app, but I encountered some problems
DemoPresenterTest
#RunWith(RobolectricTestRunner.class)
#Config(constants = BuildConfig.class, sdk = 23)
#PowerMockIgnore({ "org.mockito.*", "org.robolectric.*", "android.*" })
#PrepareForTest(DemoPresenterImpl_.class)
public class DemoPresenterTest {
#Rule
public MockitoRule rule = MockitoJUnit.rule();
private MockDemoNetworkService mMockDemoNetworkService;
private MockLceView mLceView;
private DemoPresenterImpl_ mPresenter;
#Before
public void setup() {
mMockDemoNetworkService = Mockito.mock(MockDemoNetworkService.class);
mLceView = Mockito.mock(MockLceView.class);
PowerMockito.mockStatic(DemoPresenterImpl_.class);
mPresenter = DemoPresenterImpl_.getInstance_(RuntimeEnvironment.application);
mPresenter.service = mMockDemoNetworkService;
mPresenter.view = mLceView;
}
#Test
public void testDownloadData() {
mPresenter.downloadData();
Mockito.verify(mLceView).onError(Mockito.anyInt());
}
}
DemoPresenterImpl
#EBean
public class DemoPresenterImpl implements DemoPresenter {
#Bean(DemoNetworkService.class)
DemoService service;
protected LceView<Demo> view;
/**
* download the data from server for the first time, data will be saved into the database
* and for the next time it will query the database instead
*/
#Override
#Background(delay = 1000)
public void downloadData() {
try {
List<Demo> result = service.getDemoList();
if (result != null) {
view.setData(result);
} // add else if the result is not return empty list but null
} catch (NetworkFailException e) {
view.onError(e.getResponse().getCode());
}
}
#Override
public void attach(LceView<Demo> view) {
this.view = view;
}
}
MockDemoNetworkService
public class MockDemoNetworkService implements DemoService {
#Override
public List<Demo> getDemoList() throws NetworkFailException {
NetworkFailResponse response = new NetworkFailResponse();
response.setCode(500);
throw new NetworkFailException(response);
}
#Override
public boolean setDemoList(List<Demo> demoList) {
return false;
}
}
When I run the test it returns "Cannot subclass final class class com.*.DemoPresenterImpl_", if I change to DemoPresenterImpl, the test can run but the mLceView never get called
Wanted but not invoked: mockLceView.onError();
-> at org.robolectric.RobolectricTestRunner$2.evaluate(RobolectricTestRunner.java:245)
Actually, there were zero interactions with this mock.
am I doing something wrong?
I think you can remove #PrepareForTest, because you are not mocking the presenter, you are actually testing it. Then you should use DemoPresenterImpl_, because it is containing the needed generated code.
After unsuccessful attempts to find what is the problem with my IntentService, (reading and googling) I decide to ask at stakeoverflow. I couldn't figure our what is wrong with this code. I actually want to start a service after receiving result from another activity. I do get result from that activity then comes to the method from where i want to start this service.

Intent templateCreationIntent = new Intent(getApplicationContext(), TemplateCreationService.class);
templateCreationIntent.putExtra(TemplateCreationService.PARAM_IN_MSG,userName);

I think the name of Service in the AndroidManifest.xml is not correct. It can be:
It is not the fully qualified name.
There is some spelling mistake.
Try giving full package name with the service name and give it a try.
i'm currently have a look a springboot undertow and it's not really clear (for me) how to dispatch an incoming http request to a worker thread for blocking operation handling.
Looking at the class UndertowEmbeddedServletContainer.class, it look like there is no way to have this behaviour since the only HttpHandler is a ServletHandler, that allow #Controller configurations
private Undertow createUndertowServer() {
try {
HttpHandler servletHandler = this.manager.start();
this.builder.setHandler(getContextHandler(servletHandler));
return this.builder.build();
}
catch (ServletException ex) {
throw new EmbeddedServletContainerException(
"Unable to start embdedded Undertow", ex);
}
}
private HttpHandler getContextHandler(HttpHandler servletHandler) {
if (StringUtils.isEmpty(this.contextPath)) {
return servletHandler;
}
return Handlers.path().addPrefixPath(this.contextPath, servletHandler);
}
By default, in undertow all requests are handled by IO-Thread for non blocking operations.
Does this mean that every #Controller executions will be processed by a non blocking thread ? or is there a solution to chose from IO-THREAD or WORKER-THREAD ?
I try to write a workaround, but this code is pretty uggly, and maybe someone has a better solution:
BlockingHandler.class
#Target({ElementType.TYPE})
#Retention(RetentionPolicy.RUNTIME)
#Documented
public #interface BlockingHandler {
String contextPath() default "/";
}
UndertowInitializer.class
public class UndertowInitializer implements ApplicationContextInitializer<ConfigurableApplicationContext> {
#Override
public void initialize(ConfigurableApplicationContext configurableApplicationContext) {
configurableApplicationContext.addBeanFactoryPostProcessor(new UndertowHandlerPostProcessor());
}
}
UndertowHandlerPostProcessor.class
public class UndertowHandlerPostProcessor implements BeanDefinitionRegistryPostProcessor {
#Override
public void postProcessBeanDefinitionRegistry(BeanDefinitionRegistry beanDefinitionRegistry) throws BeansException {
ClassPathScanningCandidateComponentProvider scanner = new ClassPathScanningCandidateComponentProvider(false);
scanner.addIncludeFilter(new AnnotationTypeFilter(BlockingHandler.class));
for (BeanDefinition beanDefinition : scanner.findCandidateComponents("org.me.lah")){
try{
Class clazz = Class.forName(beanDefinition.getBeanClassName());
beanDefinitionRegistry.registerBeanDefinition(clazz.getSimpleName(), beanDefinition);
} catch (ClassNotFoundException e) {
throw new BeanCreationException(format("Unable to create bean %s", beanDefinition.getBeanClassName()), e);
}
}
}
#Override
public void postProcessBeanFactory(ConfigurableListableBeanFactory configurableListableBeanFactory) throws BeansException {
//no need to post process defined bean
}
}
override UndertowEmbeddedServletContainerFactory.class
public class UndertowEmbeddedServletContainerFactory extends AbstractEmbeddedServletContainerFactory implements ResourceLoaderAware, ApplicationContextAware {
private ApplicationContext applicationContext;
#Override
public EmbeddedServletContainer getEmbeddedServletContainer(ServletContextInitializer... initializers) {
DeploymentManager manager = createDeploymentManager(initializers);
int port = getPort();
if (port == 0) {
port = SocketUtils.findAvailableTcpPort(40000);
}
Undertow.Builder builder = createBuilder(port);
Map<String, Object> handlers = applicationContext.getBeansWithAnnotation(BlockingHandler.class);
return new UndertowEmbeddedServletContainer(builder, manager, getContextPath(),
port, port >= 0, handlers);
}
#Override
public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
this.applicationContext = applicationContext;
}
}
...
override UndertowEmbeddedServletContainer.class
public UndertowEmbeddedServletContainer(Builder builder, DeploymentManager manager,
String contextPath, int port, boolean autoStart, Map<String, Object> handlers) {
this.builder = builder;
this.manager = manager;
this.contextPath = contextPath;
this.port = port;
this.autoStart = autoStart;
this.handlers = handlers;
}
private Undertow createUndertowServer() {
try {
HttpHandler servletHandler = this.manager.start();
String path = this.contextPath.isEmpty() ? "/" : this.contextPath;
PathHandler pathHandler = Handlers.path().addPrefixPath(path, servletHandler);
for(Entry<String, Object> entry : handlers.entrySet()){
Annotation annotation = entry.getValue().getClass().getDeclaredAnnotation(BlockingHandler.class);
System.out.println(((BlockingHandler) annotation).contextPath());
pathHandler.addPrefixPath(((BlockingHandler) annotation).contextPath(), (HttpHandler) entry.getValue());
}
this.builder.setHandler(pathHandler);
return this.builder.build();
}
catch (ServletException ex) {
throw new EmbeddedServletContainerException(
"Unable to start embdedded Undertow", ex);
}
}
set initializer to the application context
public static void main(String[] args) {
new SpringApplicationBuilder(Application.class).initializers(new UndertowInitializer()).run(args);
}
finaly create a HttpHandler that dispatch to worker thread
#BlockingHandler(contextPath = "/blocking/test")
public class DatabaseHandler implements HttpHandler {
#Autowired
private EchoService echoService;
#Override
public void handleRequest(HttpServerExchange httpServerExchange) throws Exception {
if(httpServerExchange.isInIoThread()){
httpServerExchange.dispatch();
}
echoService.getMessage("my message");
}
}
As you can see, my "solution" is really heavy, and i would really appreciate any help to simplify it a lot.
Thank you
You don't need to do anything.
Spring Boot's default Undertow configuration uses Undertow's ServletInitialHandler in front of Spring MVC's DispatcherServlet. This handler performs the exchange.isInIoThread() check and calls dispatch() if necessary.
If you place a breakpoint in your #Controller, you'll see that it's called on a thread named XNIO-1 task-n which is a worker thread (the IO threads are named XNIO-1 I/O-n).
I have a simple resource like:
#Path("/")
public class RootResource {
#Context WebConfig wc;
#PostConstruct
public void init() {
assertNotNull(wc);
}
#GET
public void String method() {
return "Hello\n";
}
}
Which I am trying to use with JerseyTest (2.x, not 1.x) and the GrizzlyTestContainerFactory.
I can't work out what I need to do in terms of config to get the WebConfig object injected.
I solved this issue by creating a subclass of GrizzlyTestContainerFactory and explicitly loading the Jersey servlet. This triggers the injection of the WebConfig object. The code looks like this:
public class ExtendedGrizzlyTestContainerFactory implements TestContainerFactory {
private static class GrizzlyTestContainer implements TestContainer {
private final URI uri;
private final ApplicationHandler appHandler;
private HttpServer server;
private static final Logger LOGGER = Logger.getLogger(GrizzlyTestContainer.class.getName());
private GrizzlyTestContainer(URI uri, ApplicationHandler appHandler) {
this.appHandler = appHandler;
this.uri = uri;
}
#Override
public ClientConfig getClientConfig() {
return null;
}
#Override
public URI getBaseUri() {
return uri;
}
#Override
public void start() {
if (LOGGER.isLoggable(Level.INFO)) {
LOGGER.log(Level.INFO, "Starting GrizzlyTestContainer...");
}
try {
this.server = GrizzlyHttpServerFactory.createHttpServer(uri, appHandler);
// Initialize and register Jersey Servlet
WebappContext context = new WebappContext("WebappContext", "");
ServletRegistration registration = context.addServlet("ServletContainer", ServletContainer.class);
registration.setInitParameter("javax.ws.rs.Application",
appHandler.getConfiguration().getApplication().getClass().getName());
// Add an init parameter - this could be loaded from a parameter in the constructor
registration.setInitParameter("myparam", "myvalue");
registration.addMapping("/*");
context.deploy(server);
} catch (ProcessingException e) {
throw new TestContainerException(e);
}
}
#Override
public void stop() {
if (LOGGER.isLoggable(Level.INFO)) {
LOGGER.log(Level.INFO, "Stopping GrizzlyTestContainer...");
}
this.server.stop();
}
}
#Override
public TestContainer create(URI baseUri, ApplicationHandler application) throws IllegalArgumentException {
return new GrizzlyTestContainer(baseUri, application);
}
Notice that the Jersey Servlet configuration is being loaded from the ApplicationHandler that is passed in as a parameter using the inner Application object's class name (ResourceConfig is a subclass of Application). Therefore, you also need to create a subclass of ResourceConfig for this approach to work. The code for this is very simple:
package com.example;
import org.glassfish.jersey.server.ResourceConfig;
public class MyResourceConfig extends ResourceConfig {
public MyResourceConfig() {
super(MyResource.class);
}
}
This assumes the resource you are testing is MyResource. You also need to override a couple of methods in your test like this:
public class MyResourceTest extends JerseyTest {
public MyResourceTest() throws TestContainerException {
}
#Override
protected Application configure() {
return new MyResourceConfig();
}
#Override
protected TestContainerFactory getTestContainerFactory() throws TestContainerException {
return new ExtendedGrizzlyTestContainerFactory();
}
#Test
public void testCreateSimpleBean() {
final String beanList = target("test").request().get(String.class);
Assert.assertNotNull(beanList);
}
}
Finally, for completeness, here is the code for MyResource:
#Path("test")
public class MyResource {
#Context WebConfig wc;
#PostConstruct
public void init() {
System.out.println("WebConfig: " + wc);
String url = wc.getInitParameter("myparam");
System.out.println("myparam = "+url);
}
#GET
#Produces(MediaType.APPLICATION_JSON)
public Collection<TestBean> createSimpleBean() {
Collection<TestBean> res = new ArrayList<TestBean>();
res.add(new TestBean("a", 1, 1L));
res.add(new TestBean("b", 2, 2L));
return res;
}
#POST
#Produces(MediaType.APPLICATION_JSON)
#Consumes(MediaType.APPLICATION_JSON)
public TestBean roundTrip(TestBean s) {
return s;
}
}
The output of running the test shows that the WebConfig is loaded and the init param is now available:
WebConfig: org.glassfish.jersey.servlet.WebServletConfig#107d0f44
myparam = myvalue
The solution from #ametke worked well but wasn't picking up my ExceptionMapper classes. To solve this I simplified the start() method to:
#Override
public void start() {
try {
initParams.put("jersey.config.server.provider.packages", "my.resources;my.config");
this.server = GrizzlyWebContainerFactory.create(uri, initParams);
} catch (ProcessingException | IOException e) {
throw new TestContainerException(e);
}
}
This was based on Problems running JerseyTest when dealing with HttpServletResponse
I have run into a pretty strange error that I can't get my head around.
In short: I have an ImporterBean that should read an xml file and then do stuff.
That ImporterBean is "kickstarted" by a ImporterKicker, but when I start the app
the ApplicationBean and EntityManager in the ImporterBean class are null. They are
not injected into that bean. In the KickerBean the ImporterBean and ApplicationBean are injected properly.
See code below and please tell me what I'm doing wrong(Using seam SEAM 2.2.1.CR2).
#SuppressWarnings({"UnusedDeclaration"})
#Name("importerBean")
#AutoCreate
public class ImporterBean {
private static final FilenameFilter ONLY_XML_FILES = (FilenameFilter) new SuffixFileFilter(".xml");
public static final String IN_DIR = "IN";
public static final String ERROR_DIR = "ERROR";
public static final String PROCESSED_DIR = "PROCESSED";
#In(create = true)
public ApplicationBean applicationBean;
#In
private EntityManager entityManager;
#Asynchronous
#Transactional
public void runImport(#Duration long firstStart, #IntervalDuration long startTimer) {
log.info("<118100>");
File inDir = Doing some file stuff...
}
} catch (Exception e) {
e.printStackTrace();
}
}
}
/**
* Inner class bean to kick the background tasks.
*/
#Startup
#Scope(APPLICATION)
#Name("importerKicker")
public static class ImporterKicker {
#In(create = true)
public ImporterBean importerBean;
#In(create = true)
public ApplicationBean applicationBean;
#Create
public void scheduleOptimizer() {
final int interval = applicationBean.getImporter118checkInterval();
if (interval != 0) {
importerBean.runImport(30 * MILLIS_PER_SECOND, interval * MILLIS_PER_SECOND);
} else {
}
}
}
}
This error was a symptom of this:
FullTextHibernateSessionProxy is not visible from class loader
Since you are using an Asynchronous call, you cannot use injections like that in an event scoped component.
Instead inside the Asyncrhonous method write:
#Asynchronous
#Transactional
public void runImport(#Duration long firstStart, #IntervalDuration long startTimer) {
EntityManager entityManager = (EntityManager) Component.getInstance("entityManager");
ApplicationBean applicationBean = (ApplicationBean) Component.getInstance("applicationBean",true);
log.info("<118100>");
File inDir = Doing some file stuff...
}
} catch (Exception e) {
e.printStackTrace();
}
}
}
