Problems using java annotations
Hi,
trying to use the java annotations instead of xml files to deploy a web
service some problems arise.
The web service is a simple hello world :
@javax.jws.WebService()
public class ServiceTest
{
@javax.jws.WebMethod()
public String hello()
{
return "Hello world";
}
}
It is compiled this way :
javac -cp
/usr/local/tomcat/webapps/axis2/WEB-INF/lib/axis2-jaxws-api-1.4.jar
ServiceTest.java
And deployed in a directory named "pojo" under the WEB-INF directory of the
Axis2 web application inside Tomcat :
cp ServiceTest.class /usr/local/tomcat/webapps/axis2/WEB-INF/pojo
In the "axis2.xml" configuration file :
<deployer extension=".class" directory="pojo"
class="org.apache.axis2.deployment.POJODeployer"/>
So the pojo seems to be well deployed according to the Tomcat logs :
[INFO] Deploying pojo: ServiceTest -
/usr/local/tomcat/webapps/axis2/WEB-INF/pojo/ServiceTest.class
The service and its method "hello" appear in the services list at
"http://127.0.0.1:8080/axis2/services/listServices".
But when trying to access the wsdl description file of the service at
"http://127.0.0.1:8080/axis2/services/ServiceTestService?wsdl" the result is
:
<error><description>Unable to generate WSDL 1.1 for this
service</description><reason>If you wish Axis2 to automatically generate the
WSDL 1.1, then please +set useOriginalwsdl as false in your
services.xml</reason>javax.xml.ws.WebServiceException: Error occurred

... 19 more
</error>
However the wsdl2 is available at
"http://127.0.0.1:8080/axis2/services/ServiceTestService?wsdl2".
Moreover when trying to invoke the service by using the url call
"http://127.0.0.1:8080/axis2/services/ServiceTestService/hello" the result
is :
<faultstring>Incoming message protocol does not match endpoint
protocol.</faultstring>
The same service without annotations and deployed with a "services.xml" file
as an "aar" archive in the "services" directory works fine.
So how to enable the use of annotated services by Axis2 ?
Thanks by advance for your help.

I have the same exact problem as seriousme. Were you able to find it's
solution?
It is my understanding as well that the annotations replace the need for the
"service.xml."
I just downloaded the http://metro.java.net/ metro packet; it is supposed
to gather libraries needed to use jax-ws services. I'll report here if it
solves the problem.

Thanks for your answer.
There is no "services.xml" configuration file, only the ".class" file
deployed in the "pojo" directory.
The purpose of using annotations was to avoid writting the "services.xml"
file.
Is this file mandatory even with annotations in the service implementation ?
Is it possible to put all the necessary configuration informations in the
source file ?
Thanks by advance.

please display the useOriginalWSDL param from your services.xml is should look something like
<parameter name="useOriginalwsdl">false</parameter>
thanks,
