We have bought a lot of licenses, done a lot of testing with a lot of promissing results and are on the brink of our first release :).
But now we have hit a big bump on the road, meaning we might have to abandon the bus, if we cant explain and fix it :/.
Our Distributor suddenly have control error messages like the one below:

Google tells us that this might relate to some threading issues and maybe even the way that NSB is implemented using peek/receive.
The above exception relates to this file at GitHub: https://github.com/NServiceBus/NServiceBus/blob/master/src/impl/unicast/transport/NServiceBus.Unicast.Transport.Transactional/TransactionalTransport.cs
Details about our implementation:
We use a custom IManageUnitsOfWork, due to some legacy issue which means no DTC against the DB yet. I do not think that this could be the cause, but i think its worth mentioning. This is the implemenation:
public class ManagedUnitOfWorkWithDtcSuppression : IManageUnitsOfWork
{
private readonly IContainer _container;
private IUnitOfWork _unitOfWork;
private readonly TransactionScope _scope;
public ManagedUnitOfWorkWithDtcSuppression()
{
_scope = new TransactionScope(TransactionScopeOption.Suppress);
_container = ObjectFactory.GetInstance<IContainer>();
}
public void Begin()
{
_unitOfWork = _container.GetInstance<IUnitOfWork>();
}
public void End(Exception exception = null)
{
if (exception == null)
{
_unitOfWork.Commit();
}
_unitOfWork.Dispose();
_scope.Complete();
_scope.Dispose();
}
}
Also we have a special setup where we run 4 identical AppDomains inside 1 service running, which means that when we start the service as a distributor, there are actually 4 distributors running. But these are pr. definition completely isolated from one another. The IBus is unique for each AppDomain, this has been tested.
Our Distributor configuration looks like this:
return NServiceBus.Configure.With()
.DefineEndpointName(queuePrefix)
.Log4Net(ObjectFactory.GetInstance<IServiceBusLog>().Build())
.StructureMapBuilder()
.JsonSerializer()
.AsMasterNode()
.RunDistributorWithNoWorkerOnItsEndpoint()
.MsmqTransport()
.IsTransactional(true)
.DisableTimeoutManager()
.DisableSecondLevelRetries()
.UnicastBus()
.CreateBus()
.Start(() => NServiceBus.Configure.Instance.ForInstallationOn<NServiceBus.Installation.Environments.Windows>().Install());
Question:
What is going on here?
Are we screwing with NSB because we are using DTC supression, is there a MSMQ bug or is there a NSB bug?
Let me jump in with an answer a year late! :) I'm pretty sure you're seeing https://github.com/Particular/NServiceBus/pull/2250. Basically Microsoft made changes to the implementation of MessageQueue between .NET 3.5 and .NET 4, making the NSB code non-thread safe. This was fixed in https://github.com/Particular/NServiceBus/releases/tag/3.3.10

I am new to EJB.
I am using Wildfly server.
I have session stateless Ejb as below.

I am injecting SessionContext annotated with Resource in a non ejb class as below.
public abstract class AbstractBean {
protected AbstractBean() {
log = LogMgr.getFrameworkLogger();
clsLog = LogMgr.getClassLogger(FndAbstractBean.class);
if(clsLog.debug) {
clsLog.debug("Created bean [&1]", getClass().getName());
}
}
**#Resource
protected SessionContext sessionContext;**
But when I am calling String user = sessionContext.getCallerPrincipal().getName();
it is returning "anonymous" always.
How can I solve this.
I want to get caller principal as TESTCONNECT.
Hello, this seems to be an expected behavior. The only workaround I found would be to use Interceptor,so then you can propagate the information actually. Interceptors is explained here
I want to host a WCF Rest Service with multiple contracts via mono each implemented in a separate partial class. I read many posts on similar issues, yet there was no solution for mono. I incorporated or at least tested all suggestions I could find and by now my code looks a lot like other solutions, yet does not work.
The application runs successfully on my local machine but throws an error once I deploy it via mono.
Service 'MyWebServiceEndpoint' implements multiple ServiceContract types, and no endpoints are defined in the configuration file.
Here is one of the endpoints with the contract. All the others are very much like this one. They all are a partial class MyWebServiceEndpoint implementing another contract.
namespace MyServer.MyEndPoints {
public partial class MyWebServiceEndpoint : INotificationEndpoint {
public string GetNotifications(int limit) {
// Do stuff
}
}
[ServiceContract]
public interface INotificationEndpoint {
[OperationContract]
[WebGet]
string GetNotifications(int limit);
}
}
My App.config looks like this. I removed the IP and port, as they are the server address.
<system.serviceModel>
<services>
<service name="MyServer.MyEndPoints.MyWebServiceEndpoint" behaviorConfiguration="WebService.EndPoint">
<host>
<baseAddresses>
<add baseAddress="http://ip:port>"/>
</baseAddresses>
</host>
<endpoint address="/message"
binding="webHttpBinding"
contract="MyServer.MyEndPoints.IMessageEndpoint"
behaviorConfiguration="WebBehavior"/>
<endpoint address="/music"
binding="webHttpBinding"
contract="MyServer.MyEndPoints.IMusicEndpoint"
behaviorConfiguration="WebBehavior"/>
<endpoint address="/notification"
binding="webHttpBinding"
contract="MyServer.MyEndPoints.INotificationEndpoint"
behaviorConfiguration="WebBehavior"/>
<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior name="WebService.EndPoint">
<serviceMetadata httpGetEnabled="True" />
<serviceDebug includeExceptionDetailInFaults="True"/>
</behavior>
</serviceBehaviors>
<endpointBehaviors>
<behavior name="WebBehavior">
<webHttp/>
</behavior>
</endpointBehaviors>
</behaviors>
I open the service in C# like this.
WebServiceHost = new WebServiceHost(typeof(MyWebServiceEndpoint));
WebServiceHost.Open();
The Error message I receive on mono is:
Unhandled Exception:
System.InvalidOperationException: Service 'MyWebServiceEndpoint' implements multiple ServiceContract
types, and no endpoints are defined in the configuration file. WebServiceHost can set up default
endpoints, but only if the service implements only a single ServiceContract. Either change the
service to only implement a single ServiceContract, or else define endpoints for the service
explicitly in the configuration file. When more than one contract is implemented, must add base
address endpoint manually
I hope you have some hints or someone knows how to solve the issue. Thank you already for reading up to here.
I am not familiar with Mono, Does the Mono support Webconfig file? I advise you to add the service endpoint programmatically.
class Program
{
/// <param name="args"></param>
static void Main(string[] args)
{
WebHttpBinding binding = new WebHttpBinding();
Uri uri = new Uri("http://localhost:21011");
using (WebServiceHost sh = new WebServiceHost(typeof(TestService),uri))
{
sh.AddServiceEndpoint(typeof(ITestService), binding, "service1");
sh.AddServiceEndpoint(typeof(IService), binding, "service2");
ServiceMetadataBehavior smb;
smb = sh.Description.Behaviors.Find<ServiceMetadataBehavior>();
if (smb == null)
{
smb = new ServiceMetadataBehavior()
{
HttpGetEnabled = true
};
sh.Description.Behaviors.Add(smb);
}
sh.Opened += delegate
{
Console.WriteLine("service is ready");
};
sh.Closed += delegate
{
Console.WriteLine("service is closed");
};
sh.Open();
Console.ReadLine();
sh.Close();
}
}
}
[ServiceContract]
public interface ITestService
{
[OperationContract]
[WebGet]
string GetData(int id);
}
[ServiceContract]
public interface IService
{
[OperationContract]
[WebGet]
string Test();
}
public class TestService : ITestService,IService
{
public string GetData(int id)
{
return $"{id},";
}
public string Test()
{
return "Hello " + DateTime.Now.ToString();
}
}
Result.
According to the official documentation, we had better not use Partial class.
https://learn.microsoft.com/en-us/dotnet/framework/wcf/samples/multiple-contracts
Besides, we could consider launching multiple service host for every service implemented class.
Feel free to let me know if the problem still exists.
I'm following http://www.java2blog.com/2015/09/spring-restful-web-services-json-example.html and as it's suggested in the article when I deploy my application to tomcat I get the warning:
WARNING: [SetContextPropertiesRule]{Context} Setting property 'source' to 'org.eclipse.jst.j2ee.server:restordering' did not find a matching property.
(restordering is my application context)
And when I try to access my application I get this warning:
WARNING: No mapping found for HTTP request with URI [/restordering] in DispatcherServlet with name 'restordering'
and I see a 404 error page!
I've tested this on tomcat 7 and 8. I've created the war and deployed outside of eclipse and followed all suggested solution including change in server definition (publish module context to separate XML files) and removing and adding and doing all the tricks it's described in the above article and on stackoverflow but nothing has worked so far.
Before I get "this is a warning and ..." yes it is a warning but also I get 404 error and can't access my services.
And yes I have the correct package name in my restordering-servlet.xml ( context:component-scan base-package="com.obp.restordering.controller" ).
As requested here is my web.xml:
<!DOCTYPE web-app PUBLIC
"-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"

</servlet>
<servlet-mapping>
<servlet-name>restordering</servlet-name>
<url-pattern>/*</url-pattern>
</servlet-mapping>
</web-app>
and restordering-servlet.xml is:
<beans xmlns="http://www.springframework.org/schema/beans"

<mvc:annotation-driven />
<context:component-scan base-package="com.obp.restordering.controller" />
</beans>
and my controller file is this:
package com.obp.restordering.controller;
import java.util.ArrayList;
import java.util.List;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;

import com.obp.restordering.bean.Country;
#RestController
public class CountryController {
#RequestMapping(value = "/countries", method = RequestMethod.GET, headers = "Accept=application/json")
public List<Country> getCountries() {
List<Country> listOfCountries = new ArrayList<Country>();
listOfCountries = createCountryList();
return listOfCountries;
}
#RequestMapping(value = "/country/{id}", method = RequestMethod.GET, headers = "Accept=application/json")
public Country getCountryById(#PathVariable int id) {
List<Country> listOfCountries = new ArrayList<Country>();
listOfCountries = createCountryList();
for (Country country : listOfCountries) {
if (country.getId() == id)
return country;
}
return null;
}
// Utiliy method to create country list.
public List<Country> createCountryList() {
Country indiaCountry = new Country(1, "India");
Country chinaCountry = new Country(4, "China");
Country nepalCountry = new Country(3, "Nepal");
Country bhutanCountry = new Country(2, "Bhutan");
List<Country> listOfCountries = new ArrayList<Country>();
listOfCountries.add(indiaCountry);
listOfCountries.add(chinaCountry);
listOfCountries.add(nepalCountry);
listOfCountries.add(bhutanCountry);
return listOfCountries;
}
}
Any idea?
This is embarrassing but I need to come clean and admit and provide an answer so if others have the same issue they don't circle around days as I did.
Arpit the author of the mentioned tutorial responded to my request for help and after checking my code confirmed all works as expected!
The issue was in how I was trying to access my service! If I go to /restordering/countries I get the 404 error. To access the service I need to go to /restordering/restordering/countries! As simple as that.
The warnings I still get and I can't resolve them at this time but at least the service is working and this seems more of a deployment/setting issue than actual spring development issue.
Anyways, I thought this may help some others.
Cheers
I tried to develop a rest service and expose the same via Apache Camel's CXFRS. I followed all the steps given in http://camel.apache.org/cxfrs.html and also referred to many samples given. I already referred to the question Can't find the the request for url Observer, but in my case it is a simple rest request. Below are the Service class, Route class, and cxf context used:
<?xml version="1.0" encoding="UTF-8"?>

</camel:camelContext>
</beans>
The Service Class:
package org.camelsample.rest.service;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
public class SampleRestService {
#GET
#Path("/")
public String sampleService() {
return null;
}
}
The Route Class:
package org.camelsample.rest.route;
import org.apache.camel.spring.SpringRouteBuilder;
public class SampleRestRoute extends SpringRouteBuilder {
#Override
public void configure() throws Exception {
// TODO Auto-generated method stub
from("cxfrs:bean:rsServer").log("Into Sample Route").setBody(constant("Success"));
}
}
But when I try to hit and test using http://localhost:8080/rest, I always get the following error message:
2015-05-29 13:38:37.920 WARN 6744 --- [nio-8080-exec-2] o.a.c.t.servlet.ServletController : Can't find the the request for http://localhost:8080/favicon.ico's Observer

Am using Spring boot to test the rest sample.
Does it work with this URL instead ?
http://localhost:8181/cxf/rest
If you just use address="/rest" as your address then you will probably get the default Jetty port 8181 and default CXF servlet path /cxf as the base URL.
If you specifically want to use the URL you have given then try this instead:
address="http://0.0.0.0:8080/rest"
I'm trying to write a RouteTest class for my camel jpa example and it does not work as expected because of the following line :
Bundle RouteTest is waiting for namespace handlers [http://aries.apache.org/xmlns/jpa/v1.1.0]

}

public void testRoute() throws Exception {
getMockEndpoint("mock:result").expectedMinimumMessageCount(1);
ProducerTemplate producerTemplate = new DefaultCamelContext().createProducerTemplate();
Person person = new Person();
person.setName("Bob");
producerTemplate.sendBody("direct:persist", person);
// assert expectations
assertMockEndpointsSatisfied();
}
}
you need to provide Aries Blueprint, and especially you need to provide the aries JPA dependencies. How do you Test your Routes? I'd suggest using Pax-Exam or probably better to use Pax-Exam-Karaf and intall the aries jpa features.
