Re: [xwiki-devs] I'm updating from 2.1M1 to 2.1 Final release, and encountered an error.

Hi: I'm updating from 2.1M1 to 2.1 Final release, and encountered an error.  Please someone help me out. Many thanks. I did the following things. 1. Export everything from 2.1M1 to backup.xar 2. Import backup.xar to 2.1Final 3. Import official XE XAR, effectively overwrite the things in backup.xar, with the exception of XWiki.XWikiPreference and ***.WebPreference. 4. So far so fine. But after restarting the server, I encounter the following error: HTTP ERROR 500 Problem accessing /xwiki/bin/view/Main/. Reason:    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: Could not create a DBCP pool. There is an error in the hibernate configuration file, please review it. -- -- Zhaolin Feng -- www.mapbar.com -- Currahee! We stand alone together!
