Neuron ESB User Network

The Service Bus for the Connected Business



I am new to Neuron ESB and I am practising the

Neuron Web Services resource material.

I am having issues with the

ServiceFacade and I am getting the below error:

This error just tells us that the unit test is unable to reach the Web Service hosted by Neuron.  There are several reasons why this could happen, so here's a list of things to check:

1.  Is the Neuron ESB Service properly configured?  The easiest way to check is to open ESB Explorer (run as an Administrator), and in the top toolbar there is a button labeled "Configure Server".  Click on this and the configure server dialog will open.  Verify that the ESB Configuration Folder is pointing to the folder where the ESB Solution is located.  Once verified, click OK. 

2.  Is the Neuron ESB Service started?  To check, in the same toolbar in ESB Explorer there is a dropdown that will say either Stopped, Starting or Running.  If it says Running. pick the dropdown and select Restart.  If it says Stopped, select Start from the dropdown.

3.  Verify the URL of the client connector the unit test is connecting to.  In ESB Explorer, navigate to Connections->Service Endpoints.  Verify the Orders client connector has the correct URL.

4.  Verify the Client Connector is started.  Navigate to Activity->Endpoint Health and client the Start Monitoring button.  You should see the Orders client connector in the list.  Is it in the Started or Stopped state?

If it's in the Stopped state, it may be that you already have something on your computer that is using port 80 (like IIS).  You could resolve this by changing the URL in the client connector to http://localhost:81/facade (or use some other port).  You'll also have to update this URL in the VS project.

Let me know if these steps help!


Thanks Joe for your help.

1.Neuron is configured properly. It is pointing to the proper configuration folder.
2.Neuron ESB is started and it is running state.
3. Client connector in service end point url matches with the Unit tests URL.
4. I have checked the end point health , the orders client connector is stopped state and tried to restart , but it is going back to stopped state again.

I have tried to change the port of the client connector both in the Neuron client connector end point and in the unit tests.

Much appreciated for your help.

It's still not working?  When you changed the URL in Neuron, make sure you save the solution (File->Save), and then restart Neuron ESB Service (again - I want you to do this to generate new event log/app log information).

Neuron has it's own event log.  Open the Event Viewer, then navigate to Applications and Services Logs->Neuron ESB v3.  After the restart is completed, try the test again.  Then refresh the event viewer and let me know which errors are there.

Thanks Joe,

Figured out the problem, The ESB instance doesn't have enough privileges to run. giving enough privileges solved the problem.

Adding the Order.dll to GAC , referencing the Order.dll in the process , I am having issues.

Thanks for your help.

FYI, I am using Windows server 2012 R2.

Once again thanks
