Re: [xwiki-users] Search problem

Hi, I installed xwiki on WebSphere/Oracle environment. But search function does not work properly.. It just responds as "Error 500: ". In the log file I saw the following exceptions (I didn't paste all of the stack trace) It seems Lucene does not work, and there is also a datatypes related ORACLE problem.. I'm not sure whether they are related.. Any idea? thanks, Tamer PS: XWiki version is : 1.4.1.10194 2008-08-01 21:13:51,373 [Lucene index rebuilder thread] [Lucene Index Rebuilder] ERROR lucene.IndexRebuilder - Error in lucene rebuild thread java.lang.NullPointerException at com.ibm.ws.webcontainer.srt.SRTServletRequest $SRTServletRequestHelper.access$1600(SRTServletRequest.java:2232) at com .ibm .ws .webcontainer .srt.SRTServletRequest.getQueryString(SRTServletRequest.java:1207) at com .xpn .xwiki .web.XWikiServletRequest.getQueryString(XWikiServletRequest.java:193) at com .xpn .xwiki .render .DefaultXWikiRenderingEngine.getKey(DefaultXWikiRenderingEngine.java: 335) .... 2008-08-01 21:14:18,646 [Lucene index updating thread] [Lucene Index Updater] ERROR lucene.ObjectData - error extracting fulltext for do cument xwiki:Main.AllDocs.default.objects java.lang.ClassCastException: com.xpn.xwiki.objects.StringProperty incompatible with com.xpn.xwiki.objects.ListProperty at com .xpn.xwiki.objects.BaseCollection.getListValue(BaseCollection.java: 327) ..... 2008-08-01 21:13:50,795 [http://wiki.test/bin/view/Main/] [Default : 0] ERROR impl.StatsUtil - Failed to search visit object in t he database from cookie com.xpn.xwiki.XWikiException: Error number 3223 in 3: Exception while searching documents with sql from VisitStats as obj where obj.cookie=? and obj.e ndDate > ? order by obj.endDate desc Wrapped Exception: could not execute query at com .xpn.xwiki.store.XWikiHibernateStore.search(XWikiHibernateStore.java: 2121) at com .xpn.xwiki.store.XWikiHibernateStore.search(XWikiHibernateStore.java: 2056) .....
