That sounds a lot like the dependencies aren't quite correct. We've actually just started talking about this on the dev list to come up with a way to make this much easier for app developers. Anyway, if you take a look at the helloworld sample i just committed [1] that shows about the simplest i could come up with that shows how to do what you want. You can call that webapp service by using the tuscany helloworld-ws-reference sample by changing the wsdl port location to be: http://localhost:8080/sample-helloworld-ws-service-webapp/SCA/HelloWorldComponent/HelloWorldService
I'll go try to get the calculator-webapp-ws sample working as well so there's two examples. ...ant [1] https://svn.apache.org/repos/asf/incubator/tuscany/java/sca/samples/helloworld-ws-service-webapp On 7/26/07, Radim Kolarik <[EMAIL PROTECTED]> wrote:
Hi, I made some progress with this, but it doesn't do exactly what I need it to do. In my META-INF folder, I have sca-contribution.xml file, which looks like this: <contribution xmlns="http://www.osoa.org/xmlns/sca/1.0"; targetNamespace="http://helloworld"; xmlns:sample="http://helloworld";> <deployable composite="sample:helloworldws"/> </contribution> This is my .composite file: <composite xmlns="http://www.osoa.org/xmlns/sca/1.0"; targetNamespace="http://helloworld"; xmlns:hw="http://helloworld"; name="helloworldws"> <component name="HelloWorldServiceComponent"> <service name="HelloWorldService"> <interface.java interface="helloworld.HelloWorldService"/> <binding.ws wsdlElement=" http://helloworld#wsdl.port(HelloWorldService/HelloWorldSoapPort)"/> </service> <implementation.java class="helloworld.HelloWorldImpl" /> </component> </composite> The important section in the WSDL file is: <wsdl:service name="HelloWorldService"> <wsdl:port binding="tns:HelloWorldSoapBinding" name="HelloWorldSoapPort"> <wsdlsoap:address location=" http://localhost:8090/helloworldServiceWAR/HelloWorldServiceComponent/HelloWorldService "/> </wsdl:port> </wsdl:service> Now my Tomcat is running on port 8080. As you can see, I had to specify port 8090 in WSDL, which made my service WSDL accessible via: http://localhost:8090/helloworldServiceWAR/HelloWorldServiceComponent/HelloWorldService?wsdl When I had the port in WSDL file set to 8080, I got an exception: java.net.BindException: Address already in use: bind That would suggest that some "standalone" engine is being inicialized which binds the service to port specified in WSDL. But what if I wanted the service to be handled directly by Tomcat? Would it be possible? By the way, my webapp uses the same JAR files in its WEB-INF/lib directory as were created using maven build of calculator-webapp-ws sample (I understand that I shouldn't have tuscany-sca-all-0.90-incubating.jar in web application class path).
