SpaceDataEvent does not execute on client


i am stuck with this problem of trying to have my data event handler on the client application execute on stock update event, which happens on the server (all done on the same machine).

The strange thing is that I have tried out 2 versions - the first all done in code (no xml configuration files, the second with xml configuration files) - and only the pure-code version works.

I am using gigaspaces-xapcommunity-6.5.0-ga. I would appreciate if anyone could suggest at how I else should try debug it or hint at a likely mistake?

Here are the code excerpts:

StockClientCode.java (1 file, executes and runs fine, updated stocks are displayed in the console)

package mypackage;

import org.openspaces.core.GigaSpace; import org.openspaces.core.GigaSpaceConfigurer; import org.openspaces.core.space.UrlSpaceConfigurer; import org.openspaces.events.notify.SimpleNotifyContainerConfigurer; import org.openspaces.example.stock.common.Stock;

public class StockClientCode {

public static void main(String args[]) throws InterruptedException {

    UrlSpaceConfigurer urlSpaceConfigurer = new UrlSpaceConfigurer(
    GigaSpace space = new GigaSpaceConfigurer(urlSpaceConfigurer.space())

    new SimpleNotifyContainerConfigurer(space).template(new Stock())
            .eventListenerAnnotation(new StockEventReporter()).fifo(true)




DOES NOT EXECUTE, three files, it seems that the event does not get called at all


package mypackage;

import org.openspaces.example.stock.common.GigaSpaceStockDao; import org.springframework.beans.factory.xml.XmlBeanFactory; import org.springframework.core.io.UrlResource;

public class StockClient {

public StockClient() {
    System.out.println("StockClient instantiated");

public static void main(String args[]) throws InterruptedException {

    XmlBeanFactory factory = new XmlBeanFactory(new UrlResource(

    GigaSpaceStockDao dao = (GigaSpaceStockDao) factory.getBean("stockDao");
    System.out.println("Stocks with I: "
            + dao.getStocksByFilter("I").length);

    // ((SimpleNotifyEventListenerContainer)
    // factory.getBean("accountDataNotifyContainer")).start();



package mypackage;

import org.openspaces.events.adapter.SpaceDataEvent;

public class StockEventReporter {

public StockEventReporter() {
    System.out.println("*StockEventReporter INITIALIZED*");

public void dataProcessed(Object data) {
    System.out.println("***EVENT with Spring:***: " + data);

Can you post your org.openspaces.example.stock.common.Stock?


  1. spaceantevent.xml
  2. StockClient.java

Sure, it is actually from the StockDemo example at [ http://openspaces.org/display/DAE/Ope... ]. I am trying to change the client side of the application.

You should have used Spring's ClasspathXmlApplicationContext in your StockClient. Also, the configuration for the GigaSpaceStockDao in your xml file was missing (you didn't set the localGigaSpace variable). I attached the corrected versions of these two files to this post.

I have applied your changes to the files. Everything works just fine.

Many thanks!
