Confusion over JBossWS

[Krithi Raghu]

Hi everyone...

I am trying to develop a sample web service using JBOSS. When i searched in Google, i could see that webservices in JBOSS could be developed using AXIS, JBOSSWS and WS4EE. What are all these exactly? How do we determine which one we should use for our purpose? Please throw some light on this...
I have used weblogic before and we are migrating to JBOSS now. I am still unable to develop a helloworld web service using JBOSS.

Awaiting eagerly for some reply on this...

Whitch version of JBoss do you use?

If you are using version 4.2+ you can use this User Guide for JBossWS - and it works

Just remember that this is "The JBoss way" of using the JavaEE webservice implementation, but it is almost like the real standard SUN (Glassfish) implementation.

When i compile my java class, i get this error...

An exception has occurred in the compiler (1.5.0_15). Please file a bug at the Java Developer Connection (http://java.su
n.com/webapps/bugreport)  after checking the Bug Parade for duplicates. Include your program and the following diagnosti
c in your report.  Thank you.
com.sun.tools.javac.code.Symbol$CompletionFailure: file org\jboss\lang\Annotation.class not found    

I am using JBOSS4.2.2

This is my webservice interface

package org.jboss.samples;
 
import java.rmi.Remote;
 
public interface HelloWorldInterface extends Remote {
  public String sayHello(String toWhom);
}

This is the annotated WS

package org.jboss.samples;
 
import javax.jws.WebMethod;
import javax.jws.WebService;
import javax.jws.soap.SOAPBinding; 
import javax.jws.soap.SOAPBinding.Use;
 

@WebService(name = "HelloWorld", targetNamespace="http://com.burrsutter.jbossws/helloworld")
@SOAPBinding(style = SOAPBinding.Style.RPC)
public class HelloWorldWS implements HelloWorldInterface
{
   @WebMethod
   public String sayHello(String toWhom)
   {
     System.out.println("I'm Hit! " + toWhom);
      return "Hello World: " + toWhom + " on " + new java.util.Date();
   }
}

To be able to compile your WS code, you need to add the right JBoss WS jar files to the compile classpath. Because your hello world code does not contain any JBoss specific WS code, I just used my normal 'javaee.jar' (GlassFish implementation) as the only one in the classpath - beside the JDK.

Your HelloWorld code did not work as it was (could not deploy), but I did not get any compiler errors.

I needed to add then "@Stateless" annotation to the HelloWorldWS - then the webservice could deploy on a JBoss v2.4.1.

package org.jboss.samples;
 
import javax.ejb.Stateless;
import javax.jws.WebMethod;
import javax.jws.WebService;
import javax.jws.soap.SOAPBinding; 
 
@Stateless
@WebService(name = "HelloWorld", targetNamespace="http://com.burrsutter.jbossws/helloworld")
@SOAPBinding(style = SOAPBinding.Style.RPC)
public class HelloWorldWS implements HelloWorldInterface
{
   @WebMethod
   public String sayHello(String toWhom)
   {
     System.out.println("I'm Hit! " + toWhom);
      return "Hello World: " + toWhom + " on " + new java.util.Date();
   }
}

And it gave me this WSDL:

<definitions name="HelloWorldService" targetNamespace="http://com.burrsutter.jbossws/helloworld" xmlns="http://schemas.xmlsoap.org/wsdl/" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:tns="http://com.burrsutter.jbossws/helloworld" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
 <types/>
 <message name="HelloWorld_sayHelloResponse">
  <part name="return" type="xsd:string"/>
 </message>
 <message name="HelloWorld_sayHello">
  <part name="arg0" type="xsd:string"/>
 </message>
 <portType name="HelloWorld">
  <operation name="sayHello" parameterOrder="arg0">
   <input message="tns:HelloWorld_sayHello"/>
   <output message="tns:HelloWorld_sayHelloResponse"/>
  </operation>
 </portType>
 <binding name="HelloWorldBinding" type="tns:HelloWorld">
  <soap:binding style="rpc" transport="http://schemas.xmlsoap.org/soap/http"/>
  <operation name="sayHello">
   <soap  :-o	  peration soapAction=""/>
   <input>
    <soap:body namespace="http://com.burrsutter.jbossws/helloworld" use="literal"/>
   </input>
   <output>
    <soap:body namespace="http://com.burrsutter.jbossws/helloworld" use="literal"/>
   </output>
  </operation>
 </binding>
 <service name="HelloWorldService">
  <port binding="tns:HelloWorldBinding" name="HelloWorldPort">
   <soap:address location="http://127.0.0.1:80/HelloWorldWSService/HelloWorldWS"/>
  </port>
 </service>
</definitions>

Thanks Larsen...
I still could not resolve the annotation issue. However i could develop a sample web service without using annotation. I tried writing a sample client program to invoke the web service. This was done using HttpURLConnection. But this gives the following error in the server.

I could not guess what exactly is going wrong?
A snippet of my sample client program

                Properties sysProperties = System.getProperties();
               sysProperties.put("proxyHost", "localhost");
               sysProperties.put("proxyPort", "8080");
               sysProperties.put("proxySet",  "true");
   
           String HostUrl = "localhost";
           String SoapActionUrl = "http://127.0.0.1:8080/echo/Echo?wsdl";
          
           URL url = new URL(SoapActionUrl);
               URLConnection urlconnection = url.openConnection();
               httpurlconnection = (HttpURLConnection)urlconnection;
               
               StringBuffer stringbuffer = new StringBuffer();
               
               stringbuffer.append("<SOAP-ENV:Envelope xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:SOAP-ENV=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\">");
               stringbuffer.append("<SOAP-ENV:Body>");
               stringbuffer.append("<ns1:echo xmlns:ns1=\"http://127.0.0.1:8080/\">");
               stringbuffer.append("<arg0 xsi:type=\"xsd:string\">World</arg0>");
               stringbuffer.append("</ns1:echo></SOAP-ENV:Body></SOAP-ENV:Envelope>");     
               System.out.println(stringbuffer.toString());
               byte abyte0[] = stringbuffer.toString().getBytes();
   httpurlconnection.addRequestProperty("Host", HostUrl);
               httpurlconnection.addRequestProperty("Content-Length", String.valueOf(abyte0.length));
               httpurlconnection.addRequestProperty("Content-Type", "text/xml; charset=UTF-8");
               httpurlconnection.addRequestProperty("SOAPAction", SoapActionUrl);
               httpurlconnection.setInstanceFollowRedirects(true);
               httpurlconnection.setRequestMethod("POST");
               httpurlconnection.setDoOutput(true);
               httpurlconnection.setDoInput(true);
               
               
               OutputStream outputstream = httpurlconnection.getOutputStream();
               outputstream.write(abyte0);
               outputstream.close();
   

Please guide me. In weblogic, i was able to send my xml using this program. But in JBOSS, it is giving me this error.

Hi,

If I use the webservice 'HelloWorldWS', with the '@Stateless' added to it - and I modified the SOAP to match that WSDL - everything works.

To see how the SOAP should look like, you can use SOAP UI as a client

I have modified these lines, with the right SoapActionUrl, webservice method name and namespace:

String SoapActionUrl = "http://127.0.0.1:8080/HelloWorldWSService/HelloWorldWS?wsdl";
 
stringbuffer.append("<ns1:sayHello xmlns:ns1=\"http://com.burrsutter.jbossws/helloworld\">");
 
stringbuffer.append("</ns1:sayHello></SOAP-ENV:Body></SOAP-ENV:Envelope>");

Finally I added an InputStream to be able to read from the HttpURLConnection:

InputStream in = httpurlconnection.getInputStream();
BufferedReader br = new BufferedReader(new InputStreamReader(in));
String str = "";
while ((str = br.readLine()) != null) {
   System.out.println(str);
}
in.close();
br.close();

Thanks Larsen. I could make this working now.
