String modelId = "aModelId";
String participantId = "aParticipantId";
String departmentId = "aDeparmentId";
ParticipantInfo participantInfo = getQueryService().getParticipant(participantId);
if (participantInfo instanceof OrganizationInfo) {
     OrganizationInfo organizationInfo = (OrganizationInfo) participantInfo;
     if (organizationInfo.isDepartmentScoped()) {
        Department department = getQueryService().findDepartment(null,
               departmentId, (OrganizationInfo) participantInfo);
         participantInfo = ParticipantInfoUtil.newModelParticipantInfo(
               modelId, participantId, department);
     }
}
 ActivityInstanceQuery query = ActivityInstanceQuery.findAll();
 query.getFilter().add(ActivityStateFilter.PENDING);
 query.getFilter().add(PerformingParticipantFilter.forParticipant(participantInfo));
 ActivityInstance aInstance = getQueryService().findFirstActivityInstance(query);
