[xwiki-users] Importing a xar fike and indexing by lucene

Hello, I've build my own XAR file to import pages from Oracle Database into Xwiki. The importation is OK but the pages are never indexed by Lucene. Even if I use the administration form and re-buil the index, it doesn't work. If I create a new page directly in my Xwiki, it is indexed without any problem. What's wrong with the importation ? I use the stand alone installation. Thank you very much for help Françoise Cadin
