I have written a simple hello application in Axis2 JAX-WS and when I run my
client I am getting an error that the service class cannot be found. In this
email I'm including the exact message, my services.xml file, a jar output of
my aar file, my wsdl file, my schema file, a snippet from the available
services webpage and a stacktrace from catalina.out.
I wrote the services.xml, the schema and the wsdl files by hand and
generated all the classes (except HelloClient, my client class) by "wsimport
-keep -verbose hello.wsdl".
I have tried every Google search I can think of and have looked at several
tutorials and dozens of mail archives without finding out the answer. If you
can help, I would really appreciate it.
------------------------------------------------------------------------------------------------------------------------------------------------------
The error message I get when I run the client (java -cp HelloService.jar
com/wb/hello/HelloClient) is:
"Exception in thread "main" javax.xml.ws.soap.SOAPFaultException:
java.lang.RuntimeException: The service class cannot be found for this
AxisService."
------------------------------------------------------------------------------------------------------------------------------------------------------
My services.xml file is simple:
<service name="HelloService">
<parameter name="ServiceClass">com.wb.hello.HelloService</parameter>
<operation name="hello">
<messageReceiver mep="http://www.w3.org/2004/08/wsdl/in-out";
class="org.apache.axis2.jaxws.server.JAXWSMessageReceiver"/>
</operation>
</service>
------------------------------------------------------------------------------------------------------------------------------------------------------
When I go to /cygdrive/c/tomcat-6.0.20/webapps/axis2/WEB-INF/services and
jar the aar file, the service class is there:
$ jar tvf HelloService.aar
