[Resolved] Standalone JAVA client to connect to the Bonita execution engine

I have a java class intending to conenct to the process engine via api-type "EJB3".
I have checked through the conf.bat file and have verified the properties of

a. initial context factory,
b. provider url
c. api-type

The Jaas config file contains the following entry-
BonitaAuth {
  org.ow2.bonita.identity.auth.BonitaIdentityLoginModule required;
};

BonitaStore {
  org.ow2.bonita.identity.auth.BonitaRemoteLoginModule required;
  org.jboss.security.ClientLoginModule required password-stacking=useFirstPass;
};

The exception I get here is -

Mar 27, 2012 4:44:07 PM org.ow2.bonita.util.AccessorUtil resetContext
INFO: API-Type: EJB3 has been specified through property: org.ow2.bonita.api-type

The java code for the client is -

private static final String LOGIN = "admin";
    private static final String PSSWD = "bpm";
    private static final String jaasFile = "jaas-jboss.cfg";

    public static void main(String[] args) throws Exception {
   
    //set system properties
    System.setProperty(BonitaConstants.API_TYPE_PROPERTY, "EJB3");
    /*System.setProperty(BonitaConstants.INITIAL_CONTEXT_FACTORY_PROPERTY, "org.jnp.interfaces.NamingContextFactory");
    System.setProperty(BonitaConstants.PROVIDER_URL_PROPERTY, "jnp://127.0.0.1:1099");*/
    System.setProperty(BonitaConstants.JAAS_PROPERTY, jaasFile);
   
    System.setProperty("java.naming.factory.initial", "org.jnp.interfaces.NamingContextFactory");
    System.setProperty("java.naming.provider.url", "jnp://localhost:1099");
   
    //login
    //verify the user exists
    LoginContext loginContext = new LoginContext("BonitaStore",
        new SimpleCallbackHandler(LOGIN, PSSWD));
    loginContext.login();
   
    //get he APIs
    //final ManagementAPI managementAPI = AccessorUtil.getManagementAPI();
    final RuntimeAPI runtimeAPI = AccessorUtil.getAPIAccessor().getRuntimeAPI();
    final QueryRuntimeAPI queryRuntimeAPI = AccessorUtil.getAPIAccessor().getQueryRuntimeAPI();
    final QueryDefinitionAPI queryDefinitionAPI = AccessorUtil.getAPIAccessor().getQueryDefinitionAPI();
   
    try {
       
        ProcessDefinitionUUID processUUID = new ProcessDefinitionUUID("ExternalWebAppIntegratn", "1.0");   
        ProcessDefinition process = queryDefinitionAPI.getProcess(processUUID);
        System.out.println("BonitaClientApp.main() [" + process + "]");
        //instantiate process
        ProcessInstanceUUID instanceUUID = runtimeAPI.instantiateProcess(processUUID);
        System.out.println("----------------\nNew process instance Created\n----------------");
     
        final Collection<LightTaskInstance> taskList = queryRuntimeAPI.getLightTaskList(instanceUUID, ActivityState.READY);
        if (taskList.size() != 1) {
            throw new Exception("Incorrect list size. Actual size: " + taskList.size());
        }
     
        //execute task
        final LightTaskInstance taskInstance = taskList.iterator().next();
        runtimeAPI.executeTask(taskInstance.getUUID(), true);
        System.out.println("----------------\nTask executed\n----------------");
     
        final InstanceState state = queryRuntimeAPI.getProcessInstance(instanceUUID).getInstanceState();
        /*if(!state.equals(InstanceState.FINISHED)){
            throw new Exception("Incorrect state. Actual state: " + state);
        }*/
     
        System.out.println("----------------\nApplication executed sucessfully\n----------------");
   
    } catch (Exception e) {
        e.printStackTrace();
    } finally {
      loginContext.logout();
    }
   
  }

Kindly let me knwo what I am doing wrong here.
