Dear Group, after following the guide on http://platform.xwiki.org/xwiki/bin/view/AdminGuide/InstallationGlassFish I seem to be getting an error message (see below); so far I have tried installation using GlassFish 3.0.1 on Amazon Linux and Ubuntu 11.04: both times I get the error. Any ideas? Do I have to set up a database first? Thank you in advance for useful hints, Sandor -- Error message start --- type Exception report message descriptionThe server encountered an internal error () that prevented it from fulfilling this request. exception 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: Could not create a DBCP pool.
