Comment I posted to http://blog.jelastic.com/2012/02/21/how-to-deploy-xwiki-to-jelastic-cloud-s… stating a few additional steps needed for http://platform.xwiki.org/xwiki/bin/view/AdminGuide/Installation ............................. Thanks for making this available. Jelastic is fantastic and your description got me 99% of the way there…. However, after setting up Xwiki and starting tomcat, you also need to upload, via ‘bin/import/XWiki/XWikiPreferences’ , xwiki-enterprise-ui-all-3.5.xar . However, uploading this large file into the “empty” Xwiki dies with an error that suggests max_allowed_packet is too small. http://platform.xwiki.org/xwiki/bin/view/AdminGuide/InstallationMySQL#HMySQ… changing mysql config my.cnf file from 1M to 32M ‘max_allowed_packet’ “If an empty Xwiki starts with no errors, but you unable to upload the default set of pages (XAR file) also try to increase “max_allowed_packet” parameter as shown above. ” So I changed my.cnf max_allowed_packet = 32M Then I restarted mysql while the Xwiki/tomcat instance was running. Now I’m able to upload the XAR successfully, then import the default Xwiki environment. After changing the default Xwiki ‘Admin’ password I now have a working Xwiki instance http://nielsmayer.jelastic.servint.net/ .................. I was also easily able to get "domain forwarding with masking" ( http://support.godaddy.com/help/422 ) seemingly "out of the box" as well: http://trainspodder.com/ All pretty good for a few hours of highly interrupted work. Amazing progress across-the-board both in XWiki and also easy cloud-deployment of the platform .... Especially because I've been off doing C++/QML/Javascript work using http://qt-project.org for MeeGo/Harmattan/Symbian devices, e.g. http://voicetogoog.googlecode.com http://mediatator.googlecode.com and haven't touched anything Java-related in a while. (/me breathes sigh of relief I've not been seeing inscrutable java backtraces all morning :-) ) -- Niels http://nielsmayer.com PS: For more info:on Jelastic: https://blogs.oracle.com/theaquarium/entry/jelastic_leveraging_glassfish_cl… http://www.devshed.com/c/a/Java/Jelastic-Java-PaaS-Availability-and-Pricing… http://javamomentum.be/2012/03/java-and-cloud-in-10-minutes-jelastic/ http://whyjava.wordpress.com/2012/03/05/say-hello-to-jelastic/ http://cloud.dzone.com/articles/build-cloud-jelastic-maven http://blog.jelastic.com/2012/03/19/jelastic-holy-grail-of-java-hosting/
