[xwiki-devs] Blank Xwiki after upgrading from 2.7.33656 to 4.3-milestone-1

I am upgrading from Xwiki 2.7.33656 to Xwiki 4.3-milestone-1. I also upgraded from Tomcat 5.5.33 to Tomcat 7.0.32. I installed the Xwiki as a WAR in the new instnace of Tomcat. I modified the hibernate.cfg.xml file as indicated in the install instructions. When trying to access the new Xwiki it just sits on a blank page with reference to http://localhost:8080/xwiki/bin/view/Main/. I did try to run the MYSQLDUMP file from the older Xwiki instance in the newer Xwiki instance. But each time it fails with "lost connect to mysql". Is there some difference between the MySQL databse instances of Xwiki 2.7.* and Xwiki 4.3* that could be causing this problem? Some of the log files are below... *catalina*.log *Nov 14, 2012 11:24:24 AM org.apache.catalina.startup.Catalina start INFO: Server startup in 29542 ms *localhost_access_log* 0:0:0:0:0:0:0:1 - - [14/Nov/2012:11:41:36 -0600] "GET /xwiki/ HTTP/1.1" 302 - 0:0:0:0:0:0:0:1 - - [14/Nov/2012:11:41:36 -0600] "GET /xwiki/bin/view/Main/ HTTP/1.1" 200 - *localhost.log* Nov 14, 2012 11:23:55 AM org.apache.catalina.core.ApplicationContext log INFO: ContextListener: attributeAdded('org.apache.jasper.compiler.TldLocationsCache', 'org.apache.jasper.compiler.TldLocationsCache@2b9406') -- View this message in context: http://xwiki.475771.n2.nabble.com/Blank-Xwiki-after-upgrading-from-2-7-3365… Sent from the XWiki- Dev mailing list archive at Nabble.com.
