Has been reported as such, and usually rejected, e.g.: https://hibernate.atlassian.net/browse/HHH-3715 I feel that the problem is that the XWQL-Query is not translated to HQL properly > The query we send is: > > "where doc.object(XWiki.XWikiServerClass).server = :wikiAlias and doc.name > like 'XWikiServer%’" > This is a XWQL query, however, and the HQL that is created from it (I guess its created from the query, as that is what is shown in the error message): select doc.fullName from XWikiDocument as doc , BaseObject as _o1 where ( doc.object ( XWiki.XWikiServerClass ) . server = :wikiAlias and doc.name like 'XWikiServer%' ) and doc.fullName=_o1.name and _o1.className='XWiki.XWikiServerClass' Of course the "( doc.object ( XWiki.XWikiServerClass ) . server" is not proper HQL, something must have gone amiss when translating the XWQL to HQL. What puzzles me is why this has something to do with the Oracle driver (It is no general bug for sure, otherwise it would have blocked any development ...) I just checked and I get basically the same error message when I try to execute the generated HQL "manually" (from a groovy script in a page), but of course no such error when executing the XWQL (would not have been able to start the server then). Is it possible to direct the installation temporarily to e.g. HSQL-DB (something along http://platform.xwiki.org/xwiki/bin/view/AdminGuide/InstallationHSQL ) - just for testing if the issue goes away then? (It is sure not useful for production use that way until switched back to Oracle ...) If the issue does not go away, then it must be something else ... > Do you still have the problem? > > Could you provide the exact JDBC driver and Oracle versions you use? > > Thanks > -Vincent > > [snip] > > _______________________________________________ > users mailing list > [email protected] > http://lists.xwiki.org/mailman/listinfo/users > _______________________________________________ users mailing list [email protected] http://lists.xwiki.org/mailman/listinfo/users
