Hi, For some reasons, I build XWiki Enterprise with netbeans and maven. I checkout http://svn.xwiki.org/svnroot/xwiki/enterprise/trunk, I choose project "XWiki Products - Enterprise - Web (war)", I run, and I see in my navigator : Etat HTTP 500 - javax.servlet.ServletException: com.xpn.xwiki.XWikiException: Error number 3 in 0: Could not initialize main XWiki context Wrapped Exception: Error number 3001 in 3: Cannot load class com.xpn.xwiki.store.migration.hibernate.XWikiHibernateMigrationManager from param xwiki.store.migration.manager.class Wrapped Exception: Error number 0 in 3: Exception while hibernate execute Wrapped Exception: Hibernate Dialect must be explicitly set I read in googled world there is a hibernate.cfg.xml. In my checkouted directory, there is a checkout/trunk/web/src/main/webapp/WEB- INF/hibernate.cfg.xml, but this file is empty ? Is it this file ? I read some parts on http://platform.xwiki.org/xwiki/bin/view/AdminGuide/InstallationHSQL but I can't see a complete model hibernate.cfg.xml Thanks for your help.
