    Call a web service

    Sara Rodríguez Dorrego Novice

      Hello!

      I'm new in JbossWS. I have been looking into the documentation but... I'm a bit lost. I've generated a web service that I can see at http://localhost:8080/jbossws/services. My problem is how I can access form a client application ... and if I have to produce something with wstools.

      I notice that wsdl file is automaticaly created in data folder of Jboss 4.2.2. But what happens with wsconsume tools? I've executed and this created me several files. I have to use them to call my web service? or ... I have to do something similar to

       String urlstr = "http://127.0.0.1:8080/proyecto/JbpmService?wsdl";
      
       URL url = new URL(urlstr);
      
       QName qname = new QName("http://ws/",
       "JbpmService");
      
      
       ServiceFactory factory = ServiceFactory.newInstance();
       Service service = factory.createService(url, qname);
      
      


      This second option doesn't works for me because the following exception is thrown:
      Exception in thread "main" java.lang.IllegalArgumentException: Cannot obtain wsdl service: {http://ws/}JbpmService

      how I could solucionate this problem?

      Thanks

          Yes, you use the files generated by wsconsume in your client. As an example, say you have a hello web service (I am not sowing all the code):

          class Hello {
           public String sayHello(String name) {...}
          }


          wsconsume will create an interface named Hello and a class named HelloService (and possibly other classes). The code for the client is:

          public class Client {
           public static void main(String[] args) {
           HelloService svc = new HelloService();
           Hello hello = svc.getHelloPort();
           System.out.println(hello.sayHello(args[0]));
           }
          }


          Compile the client with the classes generated by wsconsume, and package the client and the wsconsume classes info a jar file. Then use wsrunclient to run it:

          wsrunclient -classpath client.jar Hello me

            Can you make sure that the url for the wsdl is accessible? For example you can put the url in a browser location bar and make sure it shows up.

              Thanks for yours answers but I should make sth bad because it doesn't work.

              1) rphadnis: Yes, the url for the wsdl is accessible. I could see in the browser.

              2) PeterJ: I have some problems. I follow the steps you've mencionated but I don't know what's wrong. This is what occurs when I try to execute the client.

                I've put jaxb-api.jar in the lib/endorsed folder but it doesn't work.

                Any ideas?

                  The before exception was solucionated putting the libraries into the endorsed lib folder of my JAVA_HOME. But now I have another problem. I was looking information about that in google and I think that is a problem of bad situation of my files I don't now exactly. This is the exception:

                    I don't know why it's looking into ws.jaxws.Hola directory because it doesn't exist! I built it and to check what happens and now the exception is :

                    This is right. I haven't got the interface there, I have the class. So, how I have to put the files to this work fine??? Have I to create the jaxws manually to this works fine??

                      Peter Johnson Master

                      Be careful because after you use wsconsume to generate the stubs, you will have to items named ws.JbpmService. One is the web service class, the other is the interface generated by wsconsume. You want to include only the generated interface in your client's classpath.

                      Also,m are you suing wsrunclient to run the client? It build the correct classpath, you need to add in only the jar file containing your client code and the generated stubs.

                        Hello!

                        Now I'm executing from Eclipse, because I'm building an .ear that contains a dinamic web project where the web service is inside. But I got the following error:

                          Hello!!

                          I've get to call the web service from a Java application in Eclipse. I've solucionated the before error adding the library saaj-impl.jar.

                          Now I have a problem. I have jbpm-jpdl.3.2.2 installed in a remote machine.I would like to call this web service from here. But jbpm uses Jboss 4.0.4. I've added some libraries to the lib directory and I've copy the files that I've generated in the other machine (Jboss 4.2.2). I've modified the files replacing localhost with the IP where the webService exist. But it seems that it doesn't find the wsdl. I can do pings to my remote machine but if I put http://x.x.x.x:8080/proyecto/JbpmService?wsdl in the browser the system doesn't find anything.

                          Exception in thread "main" javax.xml.ws.WebServiceException: Failed to access the WSDL at: http://x.x.x.x:8080/proyecto/JbpmService?wsdl. It failed with:
