検索サービス (AbstractService) を含む osgi バンドルを実装しています。このサービスには、コンテンツ ノードのリストを NodeIterator オブジェクトとして取得するメソッドが含まれています。
public NodeIterator getNodes(Session session, String query, long count) throws RepositoryException{
NodeIterator nodeIterator = null;
QueryManager queryManager = session.getWorkspace().getQueryManager();
Query qry = queryManager.createQuery(query, Query.SQL);
qry.setLimit(count);
QueryResult result = qry.execute();
nodeIterator = result.getNodes();
return nodeIterator;
}
オンラインでエラーがあります：
QueryManager queryManager = session.getWorkspace().getQueryManager();
