Must include type attribute for handler deployment message

[sthalkidis]

Dear programmers,

I think I have sucessfully deployed a simple HelloWorld service
because by using the URL for the .wsdl file I can see it in a web
browser. However, the client for this simple service does not work.
I try to use Dynamic Invocation Interface and I always get
the org.jboss.axis.deployment.wsdd.WSDDException "Must include type attribute for handler deployment!"

I include source code for HelloClient.java the .wsdl file and the .wsdd file
below. Excuse my ignorance. Any help is valuable.

Sorry,

the code for the .wsdl and .wsdd files was not properly
shown. I repeat all of the files here for convenience.

Forgot to mention that my aim is to use a stateless EJB
as a web service. I also used the code from Wiki for
DII and get the same problem. I guess that a parameter
in the creation of the Service object is not correct
but I can not find the correct values.

Thanks in advance,

Spyros Halkidis

P.S. I am new to web services (I started taking a look
two days ago)

[thomas.diesler]

Have you looked at the samples that are attached to the wiki?

[sthalkidis]

Dear Thomas Diesler,

I took a look now at the wiki "mafia" sample and I saw that a
variable axis.home is used in the build.xml files. Isn't axis built
inside jboss-4.0.3? If not, how should I install axis inside jboss?
If yes, how should someone determine the correct axis.home
variable?

Thanks in advance,

Spyros Halkidis

I try to build the examples from Wiki for JBossWS with jboss-4.0.3
and get the following error:
Error opening C:\jboss-4.0.3\client\auth.conf: java.util.zip.ZipException
error opening zip file.

Thanks. I've seen the SLSB example and the web client for it from
the samples.
Though it is not very clear to me yet, how a simple java client and not a web client for the SLSB should be structured.
For example have noticed that when the ws4ee-samples-client.jar is deployed there is no jndi name bound to the service when I look at the logs of the server. I do not understand how the service is looked up.

Furthermore I have noticed that the ws4ee-samples-client-appl.jar does
not have any main function in the classes included. How does this client
work?

Here's a good place for you to start at:

A simple java client should have a main function or not?
My question is how does a simple java client for an SLSB
working as a web service. I am not new to J2EE,
I am new to web services.

Depends on how you gonna run your client. In the examples you've looked at the client is ran as a JUnit Test Case. If you want to run your client stand-alone, of course you will need a main method.

If you deploy ws4ee-samples-server-jse.war from the examples and you want to write a a simple java client the consumes it

Use wscompile to generate the needed artifacts from the wsdl file.
Write you main class and use of the generated artifacts

config.xml for wscompile

<configuration
 xmlns="http://java.sun.com/xml/ns/jax-rpc/ri/config">
 <wsdl location="http://localhost:8080/ws4ee-samples-server-jse/Organization?wsdl"
 packageName="show.me">
 </wsdl>
</configuration>

Your main class:

package show.me;

/**
 * A SimpleWSClient.
 *
 */
public class SimpleWSClient
{

 public static void main(String[] args)
 {
 try
 {
 OrganizationService_Impl srv = new OrganizationService_Impl();
 Organization port = srv.getOrganizationPort();
 System.out.println(port.getContactInfo("Test"));
 }
 catch (Exception e)
 {
 e.printStackTrace();
 }
 }
}

output:

The 'Test' boss is currently out of office, please call again.
