Connection Refused Error in User Guide Sample Client -- regardless of EPR

Hello!

We're trying to develop our own small axis web client. We have started by
running the client from the user guide. However, it's not cooperating. It seems
that it is not even trying to connect to the server yet, since the error message
("Connection Refused") is the same regardless of the URL we enter in the
EndpointReference targetEPR = new
EndpointReference("http://localhost/axis2/services/MyService")

We have downloaded the latest release, 0.94 of AXIS2 as a WAR file and inserted
it into Tomcat 5.5.15, which works fine. The WSDL is generated, but directing
the Browser itself to the EPR gives us a 500 HTTP error (probably no cause for
concern). Therefore we conclude that the error has to be on the client side.

We have also followed instructions from other mailing list posts telling us to
copy the addressing.mar file to the ~/.axis/modules directory, which didn't
change the error message below.

Thank you for your time.

Regards,

-- Chris & Sebastian

Hi Robert,

thanks for your fast reply. Our problem is solved now, but it wasn't due to a
faulty service. The following is only for users having the same error message:

We had changed the port to 80 on the local machine (tunneling) and recompiled
the source (That's why we didn't use localhost:8080, as Habib suggested). Then
we noticed that the .sh or .bat files of the example actually call the class
files stored in the .jar and not the ones in the directories (maybe that's a
java setting?)

After we fixed that, the test went through ok, both under Linux and Windows, on
the host where the server runs and on a remote machine.

Thanks for your help!

Re: Connection Refused Error in User Guide Sample Client -- regardless of EPR

Posted by robert <ro...@gmail.com>.

Try: 

http://localhost/axis2/listServices

When you see your service, it may be listed as faulty. Click on it, and you 
may see a stack trace. Your 500 error is probably a strong clue. You should 
also verify the results of listServices shows the Service EPR's as matching 
what you set on the client. 

Another option is to turn on logging at the debug level on both the client and 
server side. 

Lastly, you could try tcpmon or the soap monitor to see the headers comming in 
and out - probably not helpful in this case but keep it in mind for future 
problems. 

HTH,
Robert

Try using your port number as in localhost:8080
