Examples with HEAD javax.ws.rs.HEAD used on opensource projects

Example 1 with HEAD

use of javax.ws.rs.HEAD in project OpenOLAT by OpenOLAT.

the class UserWebService method getPortraitHead.

/**
 * Retrieves the portrait of an user
 * @response.representation.200.mediaType application/octet-stream
 * @response.representation.200.doc The portrait as image
 * @response.representation.404.doc The identity or the portrait not found
 * @param identityKey The identity key of the user being searched
 * @return The image
 */
@HEAD
@Path("{identityKey}/portrait")
@Produces({ "image/jpeg", "image/jpg", MediaType.APPLICATION_OCTET_STREAM })
public Response getPortraitHead(@PathParam("identityKey") Long identityKey) {
    try {
        IdentityShort identity = BaseSecurityManager.getInstance().loadIdentityShortByKey(identityKey);
        if (identity == null) {
            return Response.serverError().status(Status.NOT_FOUND).build();
        }
        File portrait = DisplayPortraitManager.getInstance().getBigPortrait(identity.getName());
        if (portrait == null || !portrait.exists()) {
            return Response.serverError().status(Status.NOT_FOUND).build();
        }
        Date lastModified = new Date(portrait.lastModified());
        return Response.ok().lastModified(lastModified).build();
    } catch (Throwable e) {
        throw new WebApplicationException(e);
    }
}

Example 2 with HEAD

use of javax.ws.rs.HEAD in project narayana by jbosstm.

the class LoggingRestATResource method headParticipant.

/**
 * Returns links to the participant terminator.
 *
 * @return Link to the participant terminator.
 */
@HEAD
public Response headParticipant(@Context UriInfo uriInfo) {
    LOG.info("LoggingRestATResource.headParticipant()");
    invocations.add("LoggingRestATResource.headParticipant()");
    String serviceURL = uriInfo.getBaseUri() + uriInfo.getPath();
    String linkHeader = new TxSupport().makeTwoPhaseAwareParticipantLinkHeader(serviceURL, false, null, null);
    return Response.ok().header("Link", linkHeader).build();
}

Example 3 with HEAD

use of javax.ws.rs.HEAD in project ovirt-engine by oVirt.

the class V3SystemServer method head.

@HEAD
public Response head() {
    // We need the V4 response for the GET method, as the response for the HEAD response doesn't contain an entity
    // and thus doesn't contain the links:
    Response response = adaptResponse(getDelegate()::get);
    // Replace the "Link" header with links calculated from the response body:
    response = replaceLinkHeader(response);
    // Clear the response body:
    response = Response.fromResponse(response).entity(null).build();
    return response;
}

Example 4 with HEAD

use of javax.ws.rs.HEAD in project OpenOLAT by OpenOLAT.

the class CertificationWebService method getCertificateInfo.

@HEAD
@Path("{identityKey}")
@Produces({ "application/pdf" })
public Response getCertificateInfo(@PathParam("identityKey") Long identityKey, @PathParam("resourceKey") Long resourceKey, @Context HttpServletRequest request) {
    if (!isAdmin(request)) {
        return Response.serverError().status(Status.UNAUTHORIZED).build();
    }
    CertificatesManager certificatesManager = CoreSpringFactory.getImpl(CertificatesManager.class);
    BaseSecurity baseSecurity = CoreSpringFactory.getImpl(BaseSecurity.class);
    Identity identity = baseSecurity.loadIdentityByKey(identityKey);
    if (identity == null) {
        return Response.serverError().status(Response.Status.NOT_FOUND).build();
    }
    OLATResourceable courseOres = OresHelper.createOLATResourceableInstance("CourseModule", resourceKey);
    OLATResourceManager resourceManager = CoreSpringFactory.getImpl(OLATResourceManager.class);
    OLATResource resource = resourceManager.findResourceable(courseOres);
    if (resource == null) {
        resource = resourceManager.findResourceById(resourceKey);
    }
    if (resource == null) {
        return Response.serverError().status(Response.Status.NOT_FOUND).build();
    }
    Certificate certificate = certificatesManager.getLastCertificate(identity, resource.getKey());
    if (certificate == null) {
        return Response.serverError().status(Response.Status.NOT_FOUND).build();
    }
    VFSLeaf certificateFile = certificatesManager.getCertificateLeaf(certificate);
    if (certificateFile == null || !certificateFile.exists()) {
        return Response.serverError().status(Response.Status.NOT_FOUND).build();
    }
    return Response.ok().build();
}

Example 5 with HEAD
