    Client web-service deployed in jboss ass fails: Can not connect http client invoker. Connection refused:connect

    christophe girardin Newbie

      Hi,

       

      I am trying to execute a web-service call within jboss 4.2.3 but i did not succeed.

       

      I used cxf-plugin to generate stubs (maven):

       

      <plugin>
                      <groupId>org.apache.cxf</groupId>
                      <artifactId>cxf-codegen-plugin</artifactId>
                      <version>${cxf.version}</version>
                      <executions>
                          <execution>
                              <phase>generate-sources</phase>
                              <configuration>
                                  <sourceRoot>${basedir}/target/jaxws</sourceRoot>
                                  <wsdlOptions>
                                      <wsdlOption>
                                          <wsdl>${basedir}/src/main/resources/topologyDiscovery.wsdl</wsdl>
                                          <extraargs>
                                              <extraarg>-verbose</extraarg>
                                          </extraargs>
                                      </wsdlOption>
                                  </wsdlOptions>
                              </configuration>
                              <goals>
                                  <goal>wsdl2java</goal>
                              </goals>
                          </execution>
                      </executions>
                  </plugin>

       

      My topologyDiscovery.wsdl file looks like:

      <?xml version="1.0" encoding="UTF-8"?>
      <wsdl:definitions targetNamespace="http://disco.lte.spi.cms.ov.hp.com" xmlns:impl="http://disco.lte.spi.cms.ov.hp.com" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:apachesoap="http://xml.apache.org/xml-soap" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:xsd="http://www.w3.org/2001/XMLSchema">

              </wsdl:port>
          </wsdl:service>
      </wsdl:definitions>

       

      and the schema file looks like:

      <?xml version="1.0" encoding="UTF-8"?>

      So the following has been generated:

      ...

           ComponentType.java

           ListTopologyResponse.java

           ObjectFactory.java

           TopologyDiscovery.java

           TopologyDiscoveryService.java

           TopologyElement.java

           TopologyElementArray.java

           TopologyFilter.java

       

      The class TopologyDiscoveryService.java is well defined based on javax.xml.ws.Service as follows:

       

      import javax.xml.namespace.QName;
      import javax.xml.ws.WebEndpoint;
      import javax.xml.ws.WebServiceClient;
      import javax.xml.ws.WebServiceFeature;
      import javax.xml.ws.Service;

       

      @WebServiceClient(name = "TopologyDiscoveryService",
                        wsdlLocation = "file:/C:/telco-spi/hpovcms-lte-spi/trunk/dev/hpovcms-lte-spi-content/src/main/resources/topologyDiscovery.wsdl",
                        targetNamespace = "http://disco.lte.spi.cms.ov.hp.com")
      public class TopologyDiscoveryService extends Service {

       

      My client is a piece of code running in my jboss 4.2.3 and executed on scheduler periodic time:

      LteDiscoScheduler.java

       

      public class LteDiscoScheduler implements Schedulable
      {
          private static final Log log = LogFactory.getLog(LteDiscoScheduler.class);

       

          private static String DISCO_URL = "classpath:/topologyDiscovery.wsdl";
          private String name;
          private long value;
          private String url;
         
          private DiscoveryService service = null;

       

          /**
           * Used ctor
           */
          public LteDiscoScheduler(String name, long value, String url)
          {
              log.info("ctor, name: " + name + ", value: " + value);
              this.name = name;
              this.value = value;
              this.url = url;
             
              // Initialize the Service class
              service = new DiscoveryService(url);
              log.info("creation TopologyDiscoveryService");
          }

       

          /**
           * Callback method invoked each iteration
           */
          public void perform(Date now, long remainingRepetitions)
          {
              log.info("perform, now: " + now +
                       ", remainingRepetitions: " + remainingRepetitions +
                       ", name: " + name + ", value: " + value);
             
              service.executeCall();
          }

       

      DiscoveryService.java

       

      public class DiscoveryService {

          private static final Log log = LogFactory.getLog(DiscoveryService.class);

       

          TopologyDiscovery discoService;

          String url;

       

          public DiscoveryService(String url) {

              log.info("DiscoveryService constructor");

              this.url = url;

              initializeService(url);

          }

       

          // Create the service client with specified wsdlurl

          private void initializeService(String url) {

              URL wsdlUrl = null;

              try {

                  wsdlUrl = new URL(url);

              } catch (MalformedURLException e) {

                  // TODO Auto-generated catch block

                  e.printStackTrace();

              }

              TopologyDiscoveryService topoDiscoService = new TopologyDiscoveryService(

                      wsdlUrl);

              discoService = topoDiscoService.getTopologyDiscoveryRequest();

          }

       

          public void executeCall() {

       

              log.info("executeCall: endPoint=" + url);

              TopologyFilter param = new TopologyFilter();

              param.setFilter("*"); // hard-coded for now

              log.info("Sending executeCall request");

              ListTopologyResponse resp = discoService.getTopology(param);          => ERROR GENERATED

              log.info("Response received");

       

              TopologyElementArray array = resp.getList();

              List<TopologyElement> list = array.getTopologyList();

              for (TopologyElement element : list) {

                  log.info("One Topology object: id=" + element.getId() + "name="

                          + element.getName() + "type=" + element.getType()

                          + "location=" + element.getLocation() + "RANname="

                          + element.getRANname());

       

                  // Access to DAO

              }

          }

       

      I package all this into my ear and deploy it in JBOSS_HOIME/.../deploy

       

      When the service is invoked, following error occurs:

      Additional Info:

      I did not add any other libs to my jboss. Do i need to add jboss sw lib ?

      I di not specify any config file (xml file) about my code to be able to make ws call where the service is implemented by other web-service ESB based. Do i need to specify any config file ?

       

      Hope someone may help me,
