I have a GWT2.6.1 application. I uses a RPC call. I defined service, serviceAsync, serviceImpl. But I consistently got following errors:
INFO: javax.servlet.ServletContext log: logLevelServlet: ERROR: The serialization policy file '/analytics/E4322B1E292CEFFC5E147EAE677D2BFF.gwt.rpc' was not found; did you forget to include it in this deployment?

}
LogLevelServiceAysnc.java
public interface LogLevelServiceAsync {

}
I cleard browser cache, and I clear the project and rebuild it. It always give the same erorr. I suppose EPARecord file has all String attributes and it is serializable. And in remote interface, it transfer array of EPARecord, it shall be ok without customerized implementation of serializable.
i take some problem.you can remove it and run again your app,if you have "inherits name='com.google.gwt.user.theme.clean.Clean'" code line into your *.gwt.xml file.
I had this problem when I wanted to connect to the local database with the GAE application. When I recreated my applications without GAE the problem disappeared.

I am trying to get IEventBroker injected into my code to send out notifications.
Everything else works but eventBroker never gets injected. I do not get any compile time errors.
It just comes up null when the code is executed.
I've trimmed the code because it wouldn't let me submit it.
Thanks for any help in advance!
package com.test.services.internal;
imports ...
#Component
public class EnvironmentServiceImpl implements IEnvironmentService {
#Inject
private IEventBroker eventBroker;
private EntityManagerFactory entityManagerFactory;
private EntityManager entityManager;
#Activate
#SuppressWarnings("unchecked")
protected void activateComponent() {
getAll(environments -> {
if (environments.isEmpty()) {
List<Environment> initialModel = getMockEnvironments();
initialModel.forEach(this::save);
}
});
}
#Deactivate
protected void deactivateComponent() {
}
#Override
public void getAll(Consumer<List<Environment>> taskConsumer) {
eventBroker.post(EnvironmentEventConstants.TOPIC_ENVIRONMENT_LOADED,
createEventData(EnvironmentEventConstants.TOPIC_ENVIRONMENT_LOADED, updateEnvironment.getId()));
}
private Map<String, String> createEventData(String topic, String environmentId) {
}
}
I followed this example https://learn.microsoft.com/pt-br/azure/app-service/webjobs-sdk-get-started and it is working fine. What I want to do is to make the connection strings (strongly typed) available in all methods within Functions class. My Connection Strings object:
namespace MyApp.Domain
{
public class Secrets
{
public class ConnectionStrings
{
public string SqlServer {get; set;}
public string Storage {get; set;}
public string SendGrid {get; set;}
public string AzureWebJobsDashboard { get; set; }
public string AzureWebJobsStorage {get; set;}
}
}
}
In web project I use (and it works perfectly):
services.Configure<Secrets.ConnectionStrings>(Configuration.GetSection("CUSTOMCONNSTR_ConnectionStrings"));
and in the classes' constructors I use:
public class EmailController: ControllerBase
{
private readonly MyEmail _myEmail;
public EmailController(MyEmail MyEmail)
{
_myEmail = MyEmail;
}
[HttpGet]
public async Task<ActionResult<string>> SendEmail()
{
try
{
...
return await _myEmail.SendMailMI3D(myMsg);
}
catch (System.Exception ex)
{
return ex.Message + " - " + ex.StackTrace;
}
}
[HttpGet("sendgrid")]
public string GetSendGrid(long id)
{
return _myEmail.SendGridConnStr();
}
}
But this way doesn't work on webjobs (console apps).
I tried to insert a simple Console.WriteLine in Functions' constructor but it doesn't work as well. So I think this is the problem: Functions' constructor is not being called. So when I insert a message in my queue I receive this error message related to DI Connection String:
Microsoft.Azure.WebJobs.Host.FunctionInvocationException: Exception while executing function: Functions.ProcessQueueMessage ---> System.NullReferenceException: Object reference not set to an instance of an object.
Can anybody please help me? Thanks a lot.
public Functions(IOptions<Secrets.ConnectionStrings> ConnectionStrings)
{
_connectionStrings = ConnectionStrings;
Console.WriteLine("Simple line");
Console.WriteLine($"Functions constructor: ${_connectionStrings.Value.SendGrid}");
}
Microsoft.Azure.WebJobs.Host.FunctionInvocationException: Exception while executing function: Functions.ProcessQueueMessage ---> System.NullReferenceException: Object reference not set to an instance of an object.
Dependency Injection is available in WebJobs but you do need to take the extra step to create an IJobActivator to define the injection.
namespace NetCoreWebJob.WebJob
{
public class JobActivator : IJobActivator
{
private readonly IServiceProvider services;
public JobActivator(IServiceProvider services)
{
this.services = services;
}
public T CreateInstance<T>()
{
return services.GetService<T>();
}
}
}
Inside Main()
var config = new JobHostConfiguration();
config.JobActivator = new JobActivator(services.BuildServiceProvider());
That should allow the runtime to utilize the parameterized constructor.

I am getting this response :

I have given the proper url then why is it taking only half of it?
I have tried the example from https://code.tutsplus.com/tutorials/sending-data-with-retrofit-2-http-client-for-android--cms-27845. This example and the link given in the example are working fine, but if I do the same with my url then I get the above error
I Hope kindly check your parsing issues may occurred.
#Override

t.printStackTrace();
}
Change your Endpoints interface for this:
public interface Endpoints {
#POST("userregister/newuser")
#FormUrlEncoded
Call<Items> newuser(#Field("Data") String Data);
}
Note that I removed the trailing slash /. This way Retrofit appends the path you defined to the BASE_URL.
refer to the docs for Retrofit.Builder for a more detailed explanation, but pay particular attention to these bits:
Base URLs should always end in /.
A trailing / ensures that endpoints values which are relative paths
will correctly append themselves to a base which has path components.
...
Endpoint values which contain a leading / are absolute.
Absolute values retain only the host from baseUrl and ignore any
specified path components.
as presently written, the path referenced in your call to Endpoints.newuser() is absolute, and therefore the path segments after the host in your base URL are dropped (as this is the documented behavior).
therefore, you should change your Endpoints interface to use relative paths instead, like so:
public interface Endpoints {
#POST("userregister/newuser")
#FormUrlEncoded
Call<Items> newuser(#Field("Data") String Data);
}
I am trying to re-use the service registrations in an assembly that I use through a few services in my solution. I follow the example listed from the NServiceBus website to implement the solution. When following that, unless I add the IWantCustomInitialization interface, my Init method (and IoC container implementation) appears not to function. When I have that interface implemented, I get exceptions (listed in SO questions here and here). I can't seem to get it to work that there are no exceptions AND the dependencies in my MessageHandler are being populated properly. Here is my current EndpointConfig implementation.
[EndpointSLA("00:00:30")]
public class EndpointConfig : IConfigureThisEndpoint, AsA_Server, UsingTransport<Msmq>, INeedInitialization {
public void Init() {
Configure.With().ObjectBuilderAdapter();
}
}
public class ObjectBuilderAdapter : IContainer {
readonly IDependencyInjector injector;
public ObjectBuilderAdapter(IDependencyInjectionBuilder dependencyInjectionBuilder) {
injector = dependencyInjectionBuilder.Create(); //This method does all the common service registrations that I am trying to re-use
//injector.RegisterType<ExtractIncomingPrincipal, PrincipalExtractor>();
}
public void Dispose() {
injector.Dispose();
}
public object Build(Type typeToBuild) {
return injector.Resolve(typeToBuild);
}
public IContainer BuildChildContainer() {
return new ObjectBuilderAdapter(new DependencyInjectorBuilder());
}
public IEnumerable<object> BuildAll(Type typeToBuild) {
return injector.ResolveAll(typeToBuild);
}
public void Configure(Type component, DependencyLifecycle dependencyLifecycle) {
injector.RegisterType(component);
}
public void Configure<T>(Func<T> component, DependencyLifecycle dependencyLifecycle) {
injector.RegisterType(component);
}
public void ConfigureProperty(Type component, string property, object value) {
if (injector is AutofacDependencyInjector) {
((AutofacDependencyInjector)injector).ConfigureProperty(component, property, value);
} else {
Debug.WriteLine("Configuring {0} for property {1} but we don't handle this scenario.", component.Name, property);
}
}
public void RegisterSingleton(Type lookupType, object instance) {
injector.RegisterInstance(lookupType, instance);
}
public bool HasComponent(Type componentType) {
return injector.IsRegistered(componentType);
}
public void Release(object instance) { }
}
public static class Extensions {
public static Configure ObjectBuilderAdapter(this Configure config) {
ConfigureCommon.With(config, new ObjectBuilderAdapter(new DependencyInjectorBuilder()));
return config;
}
}
Note: When I use the INeedInitialization interface, I get the ComponentNotRegisteredException when it's looking for IStartableBus.
When you are trying to swap the built in container, then you need to implement IWantCustomInitialization in the same class that implements IConfigureThisEndpoint.
You can use your own container and register all your types in there and tell NSB to use that container.
For example:
public class EndpointConfig : IConfigureThisEndpoint, AsA_Server, IWantCustomInitialization
{
public void Init()
{
var container = new ContainerBuilder().Build();
Configure.With()
.AutofacBuilder(container);
}
}
I am working with an API which I do not have control on, which returns XMLs.
Basically I have directory object that can contain multiple directory and file objects which are not wrapped by any tag, among few other primitive fields.
file object contains few primitive fields, and 2 lists which are wrapped by tPathList and oPathList tags.
Below is an example of such XML:
<hwreply>
<result>1</result>
<directory>
<file>
<created>DATE</created>
<modified>DATE</modified>
<name>STRING</name>
<size>INT</size>
<tPath>STRING</tPath>
<oPath>STRING</oPath>
<aPath>STRING</aPath>
<tPathList>
<tPath>STRING</tPath>
...
</tPathList>
<oPathList>
<oPath>STRING</oPath>
...
</oPathList>
</file>
<file>...</file>
...
<directory>...</directory>
<directory>...</directory>
...
<nEntries>5</nEntries>
<created>DATE</created>
<modified>DATE</modified>
</directory>
</hwreply>
I have created Directory and File objects, and OpenDirectory which is the root. When I call
OpenDirectory od = response.getEntity(OpenDirectory.class);
I get the following exception:
Exception in thread "main" java.lang.NullPointerException

Problem is solved by OP himself, adding it as an answer.
Found the problem. If it helps anyone:
setFiles(List files) in File class, should be setFiles(List<File> files).
I also had the same exception. but the solution was different. I share it here, for future problem solvers. When you invoke JAXBContext.newInstance(), have a look at the returned object.
Usually it should be of type com.sun.xml.bind.v2.runtime.JAXBContextImpl. However if it comes from some glassfish3 library like:
jar:file.../glassfish3/glassfish/modules/jaxb-osgi.jar
that threw me the same exception. A changed the order of classpath, and finally the unmarshalling worked fine, if the JAXBContext.newInstance() finds the first implementing JAXBContext class from this jar:
jar:file:.../.m2/repository/com/sun/xml/bind/jaxb-impl/2.x.x/jaxb-impl-2.x.x.jar
