Example 1 with Participant

use of org.jboss.narayana.rest.integration.api.Participant in project narayana by jbosstm.

the class RecoveryManager method recreateParticipant.

private Participant recreateParticipant(final InputObjectState inputObjectState, final String applicationId) throws IOException {
    final ParticipantDeserializer deserializer = deserializers.get(applicationId);
    final byte[] participantBytes = inputObjectState.unpackBytes();
    Participant participant = deserializer.recreate(participantBytes);
    if (participant == null) {
        final ByteArrayInputStream byteArrayInputStream = new ByteArrayInputStream(participantBytes);
        final ObjectInputStream objectInputStream = new ObjectInputStream(byteArrayInputStream);
        participant = deserializer.deserialize(objectInputStream);
    }
    return participant;
}

Example 2 with Participant

use of org.jboss.narayana.rest.integration.api.Participant in project narayana by jbosstm.

the class RecoveryManager method recreateParticipantInformation.

private ParticipantInformation recreateParticipantInformation(final RecoveryStore recoveryStore, final Uid uid) throws ObjectStoreException, IOException {
    final InputObjectState inputObjectState = recoveryStore.read_committed(uid, PARTICIPANT_INFORMATION_RECORD_TYPE);
    final String id = inputObjectState.unpackString();

        // Participant is already loaded.
        return null;
    }
    final String applicationId = inputObjectState.unpackString();
    if (!deserializers.containsKey(applicationId)) {
        // There is no appropriate deserializer.
        return null;
    }
    final String status = inputObjectState.unpackString();
    final String recoveryUrl = inputObjectState.unpackString();
    final Participant participant = recreateParticipant(inputObjectState, applicationId);
    if (participant == null) {
        // Deserializer failed to recreate participant.
        return null;
    }
    final ParticipantInformation participantInformation = new ParticipantInformation(id, applicationId, recoveryUrl, participant, status);
    if (!synchronizeParticipantUrlWithCoordinator(participantInformation)) {
        try {
            participant.rollback();
            removeParticipantInformation(participantInformation);
        // TODO is it OK to leave participant not rolled back in case of Exception?
        } catch (HeuristicException e) {
            LOG.warn(e.getMessage(), e);
        } catch (ParticipantException e) {
