Copy Files with Repository Service

Question

Hello together,
I'm a Newbie in SAP Netweaver. I have the task to create e Repository Service, that listen to one Folder and if a document is uploaded, copies the file in another folder:
Here my Code:
public class NewsTest extends AbstractRepositoryService implements IReconfigurable, IResourceEventReceiver {
     private static final String TYPE = "service.sap.com.NewsTest";
     private Collection repositoryManagers;
     private static ResourceFactory resourceFactory;
     public NewsTest() {
          super();
          // Do not add code here. Add it to startUpImpl() instead
     public String getServiceType() {
          return NewsTest.TYPE;
     protected void startUpImpl(Collection repositoryManagers)
          throws ConfigurationException, StartupException {
          this.repositoryManagers = repositoryManagers;
          for (Iterator lIt = repositoryManagers.iterator(); lIt.hasNext();) {
               IRepositoryManager lReposMgr = (IRepositoryManager) lIt.next();
               try {
                    addRepositoryAssignment((IRepositoryManager) lIt.next());
               //     resourceFactory = ResourceFactory.getInstance();
               } catch (ServiceNotAvailableException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
     protected void shutDownImpl() {
          Iterator it = repositoryManagers.iterator();
          while (it.hasNext()) {
               try {
                    removeRepositoryAssignment((IRepositoryManager) it.next());
               } catch (WcmException e) {
                    e.printStackTrace();
     protected void addRepositoryAssignment(IRepositoryManager mgr)
          throws ServiceNotAvailableException {
          // Implement this method: Usually the service registers itself for certain events at the repository manager.
          try {
               mgr.getEventBroker().register(this, new ResourceEvent(ResourceEvent.CREATE_CHILD, null));
          } catch (WcmException e) {
               // TODO Auto-generated catch block
               e.printStackTrace();
     protected void removeRepositoryAssignment(IRepositoryManager mgr)
          throws WcmException {
          // Implement this method: Usually the service must unregister itself as an event handler.
          mgr.getEventBroker().unregister(this, new ResourceEvent(ResourceEvent.CREATE_CHILD, null));
     public void reconfigure(IConfiguration config)
          throws ConfigurationException {
          this.stateHandler.preReconfigure();
          // check the new configuration data
          try {
          catch (ConfigurationException ex) {
            this.stateHandler.postReconfigure(ex);
            throw ex;
          this.config = config;
          this.stateHandler.postReconfigure();
     public void received(IEvent event) {
          IUser userid = null;
          try {
                 userid = WPUMFactory.getUserFactory().getUser("j2ee_admin");
               } catch (UserManagementException e2) {
                    // TODO Auto-generated catch block
                    e2.printStackTrace();
          RID rid = RID.getRID("/optestDB");
             ResourceContext ctx = new ResourceContext(userid);
          try {
                     IResource resource = ResourceFactory.getInstance().getResource(rid, ctx);
                     if(resource != null){
                     ICopyParameter param = new CopyParameter(true);
                     IResource copied = resource.copy(RID.getRID("/optestDB/Ziel"),param);
                     else {
                    //Resource not found
               } catch (ResourceException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
1)Why it doesn't work??The Method received(IEvent event) is called but no document will be copied...
2) Is there any way to deploy a repository service hot?? For every change i had to restart the server...
I'm Looking forward for Help!!
Regards Theresa

Theresa,
This should have been the code.
IResource resource = (IResource)event.getParameter();
Sorry for that ...
Try the modified code below....
public void received(IEvent event) {
          IUser userid = null;
          try {
               userid = WPUMFactory.getUserFactory().getUser("j2ee_admin");
          } catch (UserManagementException e) {
               // TODO Auto-generated catch block
               e.printStackTrace();
          RID rid = RID.getRID("/optestDB");
          ResourceContext ctx = new ResourceContext(userid);
//actual Document, that creates the event
          IResourceEvent myEvent = (IResourceEvent)event;
          // Wrong code IResource uploadres = myEvent.getResource();
               IResource uploadedResource = (IResource)event.getParameter();
          try {
               IResource resource = ResourceFactory.getInstance().getResource(rid, ctx);
               if(resource != null){
                    ICopyParameter param = new CopyParameter(true);
                    //IResource copied = resource.copy(RID.getRID("/optestDB/Ziel"),param);
                   IResource copied_test = uploadedResource.copy(RID.getRID("/optestDB/Ziel"),param);               
               else{
                    //resource not forund...
          } catch (ResourceException e1) {
               // TODO Auto-generated catch block
               e1.printStackTrace();
