[xwiki-users] Failed to change the Lucene Index Dir

I installed XWiki 1.4.1 with tomcat and mysql. I followed http://code.xwiki.org/xwiki/bin/view/Plugins/LucenePlugin to change the index directory. For example, xwiki.plugins.lucene.indexdir=D:/lucene . I changee the dir, saved xwiki.cfg and restarted xwiki. But the index still in the tomcat/work/lucene. Then I tried first deleted the existing index folder and files in tomcat/work. Restarted again, XWiki created new lucene folder and index files in tomcat/work. I tried several different dirs, but all the results were same. Anyone could tell me why, am I missing something? _________________________________________________________________ Windows Live Photo gallery 数码相机的超级伴侣，轻松管理和编辑照片，还能制作全景美图！ http://get.live.cn/product/photo.html
