Ich versuche Lucene Suche nach meinem Dienstprogramm zu verwenden. Die Anwendung läuft auf jboss und der Suchcode wird in eine ejb-Bean geschrieben.IllegalAccessError: org/apache/lucene/index/DirectoryReader
public List<String> textSearch(String text,String folder,String subfolder) throws IOException, RemoteException{
final String indexloc="/index/"+folder+"/"+subfolder;
IndexReader reader = DirectoryReader.open(FSDirectory.open(new File(indexloc)));
List<String> data = new ArrayList<String>();
String fileList;
try {
IndexSearcher searcher = new IndexSearcher(reader);
TopScoreDocCollector collector = TopScoreDocCollector.create(500, true);
Query q = new QueryParser(Version.LUCENE_CURRENT, "contents", analyzer).parse(text);
searcher.search(q, collector);
ScoreDoc[] hits = collector.topDocs().scoreDocs;
for(int i=0;i<hits.length;++i) {
int docId = hits[i].doc;
Document d = searcher.doc(docId);
data.add(d.get("FileName"));
}
}catch(ParseException pe)
{}
catch(Exception e) {
logger.log(Level.SEVERE,"Error:" + e);
}
return data;
}
Bei Anwendung wird die Remote-Funktion im Inneren Bean aufrufen, erhalte ich Fehler folgende:
