Submit batch jobs using the job scheduler web services interface

The job scheduler web services interface is used to programmatically submit and manipulate a batch job.

The job scheduler supports programmatic access to its functions over both an EJB interface for Java EE applications and a web services interface for both Java EE and non-Java EE applications. The Web Services Description Language (WSDL) describes the web services interface for the job scheduler that is listed under the job scheduler web services interface.

Develop and install your batch applications. This topic describes how to submit a batch job to the job scheduler. It includes a code example that demonstrates how to invoke the job scheduler web services interface.

Procedure

1. Create a program for submitting batch work.

   The following example demonstrates how to invoke the job scheduler web services interface to submit a batch job.

   Some statements are split on multiple lines for printing purposes.

   import javax.xml.namespace.QName;
    import javax.xml.rpc.Call;
    import javax.xml.rpc.ParameterMode;
    import javax.xml.rpc.Service;
    import javax.xml.rpc.ServiceException;
    import javax.xml.rpc.ServiceFactory;
    import javax.xml.rpc.encoding.XMLType;
   
       Call call = null;
    String lrsHostName = "localhost";
    String lrsPort = "9080";
   
    private String readXJCL() throws FileNotFoundException, IOException {
     // Code to read xJCL file into a String  }
   
         public void submitJob() {
          String endPoint =
             "http://"+lrsHostName+":"+lrsPort+"/LongRunningJobSchedulerWebSvcRouter/
               services/JobScheduler";
          try {
              ServiceFactory serviceFactory = ServiceFactory.newInstance();
              Service service = serviceFactory.createService(new
                 QName("http://longrun.websphere.ibm.com", "JobSchedulerService"));
   
              call = (Call) service.createCall();
           call.setProperty(Call.ENCODINGSTYLE_URI_PROPERTY,
               "http://schemas.xmlsoap.org/soap/encoding/");
           call.setProperty(Call.OPERATION_STYLE_PROPERTY, "wrapped");
           call.setPortTypeName(new
               QName("http://longrun.websphere.ibm.com", "JobSchedulerService"));
           call.setTargetEndpointAddress(endPoint);
   
           //remove all parameters from call object
   call.removeAllParameters();
           call.setReturnType(XMLType.SOAP_STRING, null);
           call.addParameter("arg", XMLType.SOAP_STRING, ParameterMode.IN);
           call.setOperationName(new QName("http://longrun.websphere.ibm.com","submitJob"));
   
      String xjcl = readXJCL(); // Method to read xJCL file into a string
   
           call.invoke(new Object[] {xjcl});
          } catch (ServiceException se) {
           System.out.println("Service Exception: " + se.getMessage());
           se.printStackTrace();
          } catch (java.rmi.RemoteException re) {
           System.out.println("Remote Exception: " + re.getMessage());
           re.printStackTrace();
          }
         }
   

2. Run the program to submit batch work.
