I am running a test under Arquillian OSGi with this code:
An annotation:
#Target(ElementType.FIELD)
#Retention(RetentionPolicy.RUNTIME)
public #interface Size {
int min() default 0;
int max() default 2147483647;
}
This class
public class FooEntity {
#Size(min = 0, max = 100)
public int number;
public int getNumber() {
return number;
}
public void setNumber(int number) {
this.number = number;
}
}
And a validation method somewhere else:
#Override
public List<String> validateEntity(Object entity) throws IllegalAccessException {
List<String> list = new ArrayList<>();
for(Field field : entity.getClass().getDeclaredFields()) {
for (Annotation annotation : field.getDeclaredAnnotations()) {
if (annotation.annotationType().getName().equals(Size.class.getName())) {
Size size = (Size) annotation; // --> Throws 'ClassCastException' exception!!
int value = field.getInt(entity);
if (value < size.min() || value > size.max())
list.add("Error Message: Invalid size.");
}
}
}
return list;
}
When I debug this part of the code, I place this same line in the 'watch' window of the IDE and it shows the code is correct, I mean, it returns annotation as Size type, but during run-time the code just breaks. Does anybody knows why is this cast not working? And why is this annotation working under a Proxy class?
Here is the StackTrace of the exception:
java.lang.ClassCastException: com.sun.proxy.$Proxy47 cannot be cast to persistence.ext.annotation.Size

Why is this cast not working?
and
You can see what it prints from the code above:
annotationType().getName() == Size.class.getName() == "persistence.ext.annotation.Size"
I suspect, that the real reason for your problems is that you have (somehow) managed to get copies of the Size interface loaded; i.e. in different classloaders. The class names appear to be the same, but if you check the classloaders (getClass().getClassLoader()), I suspect that you will find they are different.

I'm doing some integration tests for a REST API I developed. I'm trying to use Arquillian but I can't seem to find that much information about tests on RESTful webservices. I just want to test that my API returns the right String. It's a currency converter, we give an input like "USD/10/EUR" and it converts, returning a String like "10 USD -> 8.21827744904668 EUR".
Right now, this is where I'm at with the test class:
#RunWith(Arquillian.class)
public class ExchangeRateTest {
#Deployment(testable = false)
public static JavaArchive createDeployment() {
return ShrinkWrap.create(JavaArchive.class)
.addPackage(ExchangeRate.class.getPackage())
.addAsManifestResource(EmptyAsset.INSTANCE, "beans.xml");
}
#ArquillianResource
private URL base;
private static WebTarget target;
#Before
public void setUpClass() throws MalformedURLException {
Client client = ClientBuilder.newClient();
target = client.target(URI.create(new URL(base, "webresources/rates/USD/10/EUR").toExternalForm()));
}
#Test
#RunAsClient
public void testResponse(#ArquillianResource URL base) throws InterruptedException, ExecutionException {
try {
System.out.println("URL TARGET: " + target.getUri().toURL().toString());
} catch (MalformedURLException e) {
e.printStackTrace();
}
//assertEquals("10 USD -> 8.21827744904668 EUR", target.request().get().readEntity(String.class));
}
}
The following error appears:
Could not lookup value for field private java.net.URL com.mycompany.tqshw.ExchangeRateTest.base java.lang.RuntimeException at

This is my RESTful Webservice:
#Path("rates")
public class ExchangeRate {
private final CurrencyCalculator rates;
public ExchangeRate() {
rates = new CurrencyCalculator();
}
#GET
#Path("{from}/{amount}/{to}")
#Produces(MediaType.TEXT_PLAIN)
public String getRates(#PathParam("from") String from,#PathParam("amount")
String amount, #PathParam("to") String to) {
double value = 0;
try{
value = rates.convert(from, Double.parseDouble(amount), to);
}catch(RuntimeException e){
System.err.println("Currency is not available.");
}
return amount+" "+from+" -> "+value+" "+to;
}
}
I'd be more than happy if you could point me out my mistakes with the Test Class.
I have a basic Apex stream with a Kafka input operator feeding into a Couchbase set operator. The Kafka sides works fine and have proven it by removing the couch operator. I have tried switching around versions of the Malhar library to see if it was broken in the latest.
Also I am using the DataTorrent flavor of Apex.
When I add in the couch operator I get the following exception

I'm trying to create a mock object with Mockito that can be serialized. The object is an interface implementation. When this method is called, I receive an object that I want to pass to another object, hence using the doAnswer(...)-method.
This is my code.
InterfaceClass obj = mock(InterfaceClass.class, withSettings().serializable());
doAnswer(new Answer<Object>() {
public Object answer(InvocationOnMock invocation) throws Throwable {
Object[] args = invocation.getArguments();
//Here I do something with the arguments
}
}).when(obj).someMethod(
any(someObject.class));
ByteArrayOutputStream bos = new ByteArrayOutputStream();
ObjectOutput out = null;
try {
out = new ObjectOutputStream(bos);
out.writeObject(obj);
byte[] yourBytes = bos.toByteArray();
} finally {
out.close();
bos.close();
}
As far as I can tell this should be correct (I'm fairly new to Mockito).
But when Serializing my object I get this error:

The invalidInputTestCase class is the class containing the test where I'm using this code. It looks as if the mock object references this TestCase somewhere (can't find it though).
Am I not correctly implementing this or better ideas to mock?
If you want to serialize a mock everything needs to be serializable, including the Answer.
And actually that's what the JDK is telling you :
java.io.NotSerializableException: com.trust1t.ocs.signcore.test.InvalidInputTestCase$1
where InvalidInputTestCase$1 is the name of the anonymous Answer.
To make it serializable you have to create a class implementing Answer and Serializable.
Also note that serialization across classloaders (JVM) is not yet released, at the moment you can only serialize and deserialize a mock in the same classloader.
Is there a way to ensure that the serialization of an object is done correctly?
I created an applet that I serialize with writeObject() method and I have no Exception no error.
But when I try to de-serialize it with readObject() I got a NullPointerException.
My applet is kinda complex but I ensured that all my fields are serializable.
The class of the objection have nested classes.
Any guess as to what could have happen?
the code below is in my servlet it creates a SerialTree .
` SerialTree st = new SerialTree() ;
try{
ObjectOutputStream out = new ObjectOutputStream(new FileOutputStream("/home/cof/test8"));
out.writeUnshared(st);
out.flush();
out.close();
}
Here's the stacktrace :

here the lines 70 to 106 to the applet itself ,it tries to retrieve a serilaTree object ?
`
try{
result = new ObjectInputStream(new FileInputStream("/home/cof/test8"));
}
catch(NotSerializableException e){
e.printStackTrace();
}
catch(InvalidClassException e){
e.printStackTrace();
}
catch(StreamCorruptedException e){
e.printStackTrace();
}
catch(NotActiveException e){
e.printStackTrace();
}
catch(OptionalDataException e){
e.printStackTrace();
}
Object obj =null;
try{
obj = result.readObject();
}
catch(NullPointerException e){
e.printStackTrace();
// System.out.println("lalal");
}
catch(NotSerializableException e){
e.printStackTrace();
}
catch(InvalidClassException e){
e.printStackTrace();
}
catch(StreamCorruptedException e){
e.printStackTrace();
}
To me, it doesn't make sense to ser/deser the type Applet. Try using a different class.
Update:
I have read your stacktrace, and what I see is that you tried to deserialize an applet while running an applet. I strongly suspect this to be the reason of your problem. Try moving all your variables into a different class (call it MySerializableApplet for example, and don't make it extend the class Applet), then operate your serialisation/deserialization on this one only.
