http://issues.apache.org/bugzilla/show_bug.cgi?id=30538 Deleting of non-empty-collections does not work [EMAIL PROTECTED] changed: What |Removed |Added ---------------------------------------------------------------------------- Severity|Critical |Major Summary|SymbolTables get lost |Deleting of non-empty- |sometimes |collections does not work ------- Additional Comments From [EMAIL PROTECTED] 2004-08-17 16:34 ------- After hours of investigation I found a reason. The following happened: At first my system tries to delete some collection 'name' (which is not empty and may have subcollections) within a collection 'path' by col = org.xmldb.api.DatabaseManager.getCollection(m_dbURL + path); CollectionManagementService service = (CollectionManagementService) col.getService("CollectionManagementService", "1.0"); service.removeCollection(name); After that I want to import the same collection, resources again, but before I do this I check if these files exist by checking if org.xmldb.api.DatabaseManager.getCollection(m_dbURL + path).getResource(id) != null This returns true for the resources within my collection I thought I had deleted, resulting in the situation that the collection is created again (containing the old documents, which somehow have not been deleted completely), but the SymbolTable is empty, which then leads to NullPointerExceptions if accessing these documents. To make this even more confusing this seems only to happen if I reload my webapplication (XIndice is running embeded under Tomcat 5) before I start deleting the collection. If I restart the whole Tomcat server this does not happen. A workaround I found out is now to recursively delete all subcollections and resources within the collection first and then removing the empty collection. Bjoern Eickvonder
