Example 1 with WonMessageBuilder

use of won.protocol.message.WonMessageBuilder in project webofneeds by researchstudio-sat.

the class NeedManagementService method deactivateNeed.

public void deactivateNeed(URI needURI, String optionalMessage) {
    if (needURI == null) {
        logger.warn("deactivateNeed called but needUri is null - doing nothing");
        return;

    logger.debug("Deactivating need {}", needURI);
    // check if we have that need (e.g. it's not a need living on another node, or does not exist at all)
    Need need = needRepository.findOneByNeedURI(needURI);
    if (need == null) {
        logger.debug("deactivateNeed called for need {} but that need was not found in the repository - doing nothing");

the class VerifyAndSignExamples method ownerCreateNeedMsg.
