Problema, Domanda

Ottieni la seguente eccezione quando tenti di eseguire una query xpath che contiene un nodo che ha un nome che inizia con una cifra.

Causato da: javax.jcr.query.InvalidQueryException: Parse error: data is not a RelationQueryNode at org.apache.jackrabbit.core.query.xpath.XPathQueryBuilder.visit(XPathQueryBuilder.java:504) at org.apache.jackrabbit.core.query.xpath.SimpleNode.jjtAccept(SimpleNode.java:80) at org.apache.jackrabbit.core.query.xpath.SimpleNode.childrenAccept(SimpleNode.java:89) at org.apache.jackrabbit.core.query.xpath.XPathQueryBuilder.visit(XPathQueryBuilder.java:551) at org.apache.jackrabbit.core.query.xpath.SimpleNode.jjtAccept(SimpleNode.java:80) at org.apache.jackrabbit.core.query.xpath.SimpleNode.childrenAccept(SimpleNode.java:89) at org.apache.jackrabbit.core.query.xpath.XPathQueryBuilder.visit(XPathQueryBuilder.java:551) at org.apache.jackrabbit.core.query.xpath.SimpleNode.jjtAccept(SimpleNode.java:80) at org.apache.jackrabbit.core.query.xpath.SimpleNode.childrenAccept(SimpleNode.java:89) at org.apache.jackrabbit.core.query.xpath.XPathQueryBuilder.visit(XPathQueryBuilder.java:551) at org.apache.jackrabbit.core.query.xpath.SimpleNode.jjtAccept(SimpleNode.java:80) at org.apache.jackrabbit.core.query.xpath.SimpleNode.childrenAccept(SimpleNode.java:89) at org.apache.jackrabbit.core.query.xpath.XPathQueryBuilder.visit(XPathQueryBuilder.java:551) at org.apache.jackrabbit.core.query.xpath.SimpleNode.jjtAccept(SimpleNode.java:80) at org.apache.jackrabbit.core.query.xpath.SimpleNode.childrenAccept(SimpleNode.java:89) at org.apache.jackrabbit.core.query.xpath.XPathQueryBuilder.visit(XPathQueryBuilder.java:551) at org.apache.jackrabbit.core.query.xpath.SimpleNode.jjtAccept(SimpleNode.java:80) at org.apache.jackrabbit.core.query.xpath.SimpleNode.childrenAccept(SimpleNode.java:89) at org.apache.jackrabbit.core.query.xpath.XPathQueryBuilder.visit(XPathQueryBuilder.java:551) at org.apache.jackrabbit.core.query.xpath.SimpleNode.jjtAccept(SimpleNode.java:80) at org.apache.jackrabbit.core.query.xpath.SimpleNode.childrenAccept(SimpleNode.java:89) at org.apache.jackrabbit.core.query.xpath.XPathQueryBuilder.visit(XPathQueryBuilder.java:551) at org.apache.jackrabbit.core.query.xpath.SimpleNode.jjtAccept(SimpleNode.java:80) at org.apache.jackrabbit.core.query.xpath.SimpleNode.childrenAccept(SimpleNode.java:89) at org.apache.jackrabbit.core.query.xpath.XPathQueryBuilder.createPathQueryNode(XPathQueryBuilder.java:734) at org.apache.jackrabbit.core.query.xpath.XPathQueryBuilder.visit(XPathQueryBuilder.java:372) at org.apache.jackrabbit.core.query.xpath.SimpleNode.jjtAccept(SimpleNode.java:80) at org.apache.jackrabbit.core.query.xpath.XPathQueryBuilder.<init>(XPathQueryBuilder.java:297) at org.apache.jackrabbit.core.query.xpath.XPathQueryBuilder.createQuery(XPathQueryBuilder.java:331) at org.apache.jackrabbit.core.query.xpath.QueryBuilder.createQueryTree(QueryBuilder.java:39) at org.apache.jackrabbit.core.query.QueryParser.parse(QueryParser.java:57) at org.apache.jackrabbit.core.query.lucene.QueryImpl.<init>(QueryImpl.java:91) at com.day.crx.query.lucene.CRXExecutableQueryImpl.<init>(CRXExecutableQueryImpl.java:64) at com.day.crx.query.lucene.LuceneHandler.createExecutableQuery(LuceneHandler.java:381) at org.apache.jackrabbit.core.query.QueryImpl.init(QueryImpl.java:127) at org.apache.jackrabbit.core.SearchManager.createQuery(SearchManager.java:305) at org.apache.jackrabbit.core.query.QueryManagerImpl.createQuery(QueryManagerImpl.java:94)

Risoluzione, risposta

Usa questo metodo per codificare il nome del nodo numerico usando il seguente metodo: org.apache.jackrabbit.util.ISO9075.encode(name)
O in alternativa usa JCR SQL invece di XPath.

Si applica a

CRX 1.x
