    quickstart helloworld client

    Roland Wiesemann Newbie

      Hello,

      i have attempt the esb sample quickstart->helloworld on a jboss environment JBaoss-AS-4.2.0. It works excellently.

      Now, i want to refactor the sample 'SendEsbMessage' from the ant launcher to my own console-client like:

      public class SendEsbMessage
      {
       public static void main(String args[]) throws Exception
       {
      // Setting the ConnectionFactory such that it will use scout
       System.setProperty( "javax.xml.registry.ConnectionFactoryClass" ,"org.apache.ws.scout.registry.ConnectionFactoryImpl");
      
       Message esbMessage = MessageFactory.getInstance().getMessage();
      
       esbMessage.getBody().setByteArray( "Hello - Straight to ESB listener - no Gateway".getBytes());
      
       new ServiceInvoker("FirstServiceESB", "SimpleListener").deliverAsync(esbMessage);
       }
      }
      

      It is exactly the 'quickstart->helloworld' sample.

      To start the application, i have to provide all necesary libraries for a JBoss-Esb client sending esb messages.

      The sample from the ant context use a very big class-path:
      classpath refid="exec-classpath".
      I have printed this content with
      <pathconvert property="formatted-path" refid="exec-classpath"
       pathsep="${line.separator}" />
      <echo message="path = ${formatted-path}" />
      

      and found nearly all jars on server side.

      Can you tell me, what is the necessary subset of jar files for this sample?

      I have provide all this jar files to my sample and the configuration files:
      - jbossesb-properties.xml
      - jndi.properties
      - juddi.properties
      - log4j.xml
      from the 'quickstart->helloworld' sample.
      But the result is not the same as from 'quickstart->helloworld'.
      The result is a exception:

      Can you tell me, what is the reason for this?

      Thank you.

          if you look at the helloworld quickstart sample, you'll find a few additional files in the "root" of the project.
          jbossesb-properties.xml
          jndi.properties
          juddi.properties
          log4j.xml

          I believe all 4 of these are required for the client you are trying to build. And you are right, we should clearly indicate which jar files are needed by a remote client. That is something we'll need to work on.
