Problem Query/Retrieve wirt dcm4che 3

[Andreas Beckers]

Hi,

I have a server which is offering pacs functionallity by using dcm4che 3. Everything work well if I use OsiriX to access my server. But with Query/Retrieve I have some problems when I use an other clean than OsiriX. When I use K-PACS or Synedra Personal, the query part works, but when I request to send the images a new Association is initiated, negociation ok, data is send. But when all data is send, I get no Respone. Sometimes I get an abort.

Here is my code to build the new Association:

    Association associateToTarget(Association as, Attributes rq) throws SQLException, DicomServiceException, IOException, InterruptedException,
            IncompatibleConnectionException, GeneralSecurityException {
        String destName = rq.getString(Tag.MoveDestination);
        DcmFacilityPdm node = IDicomTX.FACTORY.get().findFacilityByAETitle(destName);
        if (node == null) {
            throw new DicomServiceException(Status.MoveDestinationUnknown, destName + " not registered in ixserv");
        }
        ApplicationEntity destAE = new ApplicationEntity(destName);
        Connection conn = new Connection(destName, node.getDfcHost(), node.getDfcPort());
        destAE.addConnection(conn);
        Device device = new Device(destAE.getAETitle());
        device.addConnection(conn);
        device.addApplicationEntity(destAE);
        AAssociateRQ ac = new AAssociateRQ();
        ac.setCalledAET(destName);
        ac.setCallingAET(as.getCalledAET());
        int idx = 0;
        for (String cuid : SCU_CLASSES) {
            ac.addPresentationContext(new PresentationContext(++idx, cuid, DcmSCP.NON_RETIRED_LE_TS));
        }
        Association dest = as.getApplicationEntity().connect(destAE, ac);
        return dest;
    }

I use an implementation of org.dcm4che.net.service.RetrieveTask which is mostly a copy of org.dcm4che.net.service.BasicRetrieveTask but with the Instance-Locator replaced by my own infrastructure.
One thing I had to change, was to add an role selection in the run method:

                    if (pendingRSP)
                        writePendingRSP();
                    try {
                        storeas.getAAssociateAC().addRoleSelection(new RoleSelection(inst.getCUID(), true, true));
                        cstore(storeas, inst);
                    }
                    catch (Exception e) {
                        failed.add(inst.getIUID());
                        status = Status.UnableToPerformSubOperations;
                        LOG.warn(as + ": Unable to perform sub-operation on association to " + storeas.getRemoteAET(), e);
                    }

Has anybody an idea what I am doing wrong?

Yours, Andreas
