SAP Repository Framework Events

[Former Member]

Hi all,

I created a respository service to update a custom km property when I received the event checkIn. The problem is it execute es very slow and after I have this error:

This is the method and I don't understand where is the problem...

public void received(IEvent event) {

  try {

  if (event!=null){

       IResourceEvent myEvent = (IResourceEvent) event;

           IResource res = myEvent.getResource();

           PropertyName propertyNamePublicado =

                        new PropertyName("namespace","prp_Publicado");

       IProperty propPublicado = res.getProperty(propertyNamePublicado);

          if (myEvent.getType() == ResourceEvent.CHECKIN)

            {

        if(propPublicado!=null){

            boolean pub=false;

        IMutableProperty mutableProperty = propPublicado.getMutable();

        mutableProperty.setBooleanValue(pub);

        res.setProperty(mutableProperty);

         }

        else{

           IProperty proPublic = new Property(propertyNamePublicado,Boolean.FALSE);

           res.setProperty(proPublic);

          }//else

            }//if  checkin

  }//IF   event null 

   }//try

  catch (ResourceException e) {

  e.printStackTrace();

  }

Thanks and regards

Hi,

I have modified my method this is the source code:

public void received(IEvent event) {

  try {

  if (event!=null){

       IResourceEvent myEvent = (IResourceEvent) event;

           IResource res = myEvent.getResource();

           IPropertyName propertyNamePublicado =

                        new PropertyName("namespace","prp_Publicado");

       IProperty propPublicado = res.getProperty(propertyNamePublicado);

          if (myEvent.getType() == ResourceEvent.CHECKIN)

            {

       // IMutableProperty mutableProperty = propPublicado.getMutable();

       // mutableProperty.setBooleanValue(false);

       //  res.setProperty(propPublicado); 

            }//if  checkin

  }//IF   event null  

   }//try

  catch (ResourceException e) {

  e.printStackTrace();

  }

  }

I commented the 3 lines where I modify the property and I tested again it is the trace error:

The source you provided seems to doesnt match the exception, Im not able to see any use of InputStream. You have to take a look to at com.sap.util.monitor.grmg.GrmgRequest.<init>(GrmgRequest.java:75). The service you have wrote seems to provocate this somehow, so it has to be presented in the stack trace, if I got you properly. Hang in there with NWDS and debug if you are not sure whats going wrong. The trace is a bit too short, you are not able to more in the logs regarding this issue? No "caused by" or any attendant exceptions?

Hi,

Yes the trace was about a problem with nwa.

Now I can read the event check-in , I need to change the property value to false.

When is receiving the event checkin, the property change but the property value  is not saving in my IResource..

I following this page: http://help.sap.com/saphelp_nw73/helpdata/en/43/9cbe501fa925b3e10000000a1553f7/content.htm

if (myEvent.getType() == ResourceEvent.CHECKIN)

            {

                      IMutableProperty mutableProperty = propPublicado.getMutable();

                       mutableProperty.setBooleanValue(false);

                       res.setProperty(propPublicado);

            }//if  checkin

I haven't any error, the property seems to have changed but when I refresh my KM or I work with other document,the property reverts to the previous value.

what is the problem??

Thanks! and regards

Mónica
