NOTE, the instructions here have been updated a little for GlassFish ESB v2.1 since its release.

A lot of the demos until this point have illustrated Scheduler BC consuming a BPEL SE, so how 'bout consuming a 'cup of Jo' instead?  POJO that is. 

We'll now show how to have Scheduler BC trigger a POJO SE to execute a Windows (2000, XP, Vista) command that pops up a dialog with some greeting.  Of course, you can adapt this to do more useful things like 'downloading a file from some remote site so that File BC can pick it up and send it to BPEL SE for processing'...but then that'll be work and fun is good!

Prerequisites: Scheduler BC now comes pre-installed with GF ESB v2.1, but you'll need to install POJO SE (installer here).

1. Create a Java (SE) Application project, keeping the default Main class, although it won't be used here (but it's needed due to a POJO SE project idiosyncrasy):

   

2. Right-click the schedpojodemo package and add a New | Other | ESB | POJO for Binding:

   

3. Specify that the POJO SE is to work with Scheduler BC by:

   

4. Select Next and Add a Simple Trigger:

   

   The Windows command chosen here in the trigger Message is long so you can copy it from here:

   echo MsgBox "Howdy ${user.name}, it's ${org.glassfish.openesb.scheduler.inbound.date} and all's well!", 0, "Sched POJO Demo" > ${java.io.tmpdir}\howdy.vbs & wscript.exe ${java.io.tmpdir}\howdy.vbs

   

5. Select Next and Choose Node for the Input Argument Type in the POJO method that will be doing the providing:

   

6. Select Finish and in the SchedPojoBinding.java Java editor that shows up, fix the package import warning for Node (answer: org.w3c.dom.Node):

   

7. Copy the imports below into the same class, pasting it before the first import statement that's already there:

   import java.io.BufferedReader;
   import java.io.IOException;
   import java.io.InputStream;
   import java.io.InputStreamReader;
   import java.util.ArrayList;
   import java.util.List;
   import java.util.logging.Level;
               

8. Copy the code below into the same class, pasting it just above the line that declares "private static final Logger logger":

       private void FireTriggerOperation(String input) {
           List args = new ArrayList();
           if (System.getProperty("os.name").toLowerCase()                 //NOI18N
                   .startsWith("windows")) {                               //NOI18N
               args.add("cmd.exe");                                        //NOI18N
               args.add("/c");                                             //NOI18N
           }
           args.add(input);
           ProcessBuilder procBuilder = new ProcessBuilder(args);
           try {
               Process proc = procBuilder.start();
               StreamEater stdOutEater =
                       new StreamEater(proc.getInputStream(), "StdOut");   //NOI18N
               StreamEater stdErrEater =
                       new StreamEater(proc.getErrorStream(), "StdErr");   //NOI18N
               stdOutEater.start();
               stdErrEater.start();
               int rc = proc.waitFor();
               logger.info("Command \"" + input + "\" exit code: " + rc);  //NOI18N
           } catch (IOException ex) {
               logger.log(Level.SEVERE, "Unknown command? " + input, ex);  //NOI18N
               return;
           } catch (InterruptedException ie) {
               logger.log(Level.WARNING, "Command aborted!");              //NOI18N
           }
       }
   
       private class StreamEater extends Thread {
   
           private BufferedReader rdr;
           private String name;
   
           public StreamEater(InputStream is, String name) {
               super(name + "-Eater");                                     //NOI18N
               rdr = new BufferedReader(new InputStreamReader(is));
               this.name = name;
           }
   
           @Override
           public void run() {
               String line = null;
               try {
                   while ((line = rdr.readLine()) != null) {
                       logger.info(name + "> " + line);                    //NOI18N
                   }
               } catch (IOException ex) {
                   logger.log(Level.SEVERE, "Problem reading " + name, ex);//NOI18N
               }
               try {
                   rdr.close();
               } catch (IOException ex) {
                   // ignore
               }
               rdr = null;
           }
       }
   
       public static void main(String[] args) throws Throwable {
           SchedPojoBinding spb = new SchedPojoBinding();
           spb.FireTriggerOperation("echo MsgBox \"Howdy, all's well!\", " //NOI18N
                   + "0, \"Scheduler POJO Demo\" > C:\\temp\\howdy.vbs & " //NOI18N
                   + "wscript.exe C:\\temp\\howdy.vbs");                   //NOI18N
       }
   

9. In the FireTriggerOperation(Node inupt) method, add this call:

   

10. From here on, it's pretty much mundane...Save this project and create a new Composite Application project
11. Drag the SchedPojoDemo project into the Service Assembly canvas and do a Build Project
12. Deploy the CASA project and voila, you got your popup!
