Re: [xwiki-devs] Using Glassfish managed datasource

Hi, i managed to solve the problems i had trying to use a Glassfish defined DataSource. Here's how: -Do not be creative giving JNDI names in your app server, you must create a DataSource named exactly jdbc/XWikiDS, which is the name that appears inside WEB-INF/web.xml and probably is the name used inside XWiki code -Uncomment the <resource-ref> element inside WEB-INF/web.xml <resource-ref> <description>DB Connection</description> <res-ref-name>jdbc/XWikiDS</res-ref-name> <res-type>javax.sql.DataSource</res-type> <res-auth>Container</res-auth> </resource-ref> -Use the following connection.datasource property inside WEB-INF/hibernate.cfg.xml: <property name="connection.datasource">java:comp/env/jdbc/XWikiDS</property> -Do not forget to use this (inside WEB-INF/hibernate.cfg.xml), don't comment it out, as was nicely explained in the documentation link below. <property name="dialect">org.hibernate.dialect.MySQLDialect</property> -Do not comment out the <mapping> elements inside WEB-INF/hibernate.cfg.xml <mapping resource="xwiki.hbm.xml"/> <mapping resource="feeds.hbm.xml"/> <mapping resource="activitystream.hbm.xml"/> And now it works, using XWiki Enterprise stable 2.1.1 and Glassfish v3 build 74.2 I hope you don't mind i modified the documentation here http://platform.xwiki.org/xwiki/bin/view/AdminGuide/Installation so that it's more clear about the JNDI name to use and not commenting out the <mapping> elements Thank you !

In short, does anyone know how to tweak WEB-INF/hibernate.cfg.xml so that Hibernate uses a JNDI resource that has been configured in Glassfish? (for instance, i've defined jdbc/xwiki in Glassfish and would like Hibernate to use it instead of the settings provided inside WEB-INF/hibernate.cfg.xml). The long version: I'm trying to do a manual installation (as in: http://platform.xwiki.org/xwiki/bin/view/AdminGuide/Installation#HInstallin… ) on a Glassfish v3 app server, and would like to use a Glassfish managed datasource (let's say using JNDI jdbc/xwiki as javax.sql.DataSource). I haven't found explicit details on how to do this, so i started by commenting out line xwiki.store.hibernate.path=/WEB-INF/hibernate.cfg.xml inside file WEB-INF/xwiki.cfg and uncommenting the following inside WEB-INF/web.xml so that it's used instead: <resource-ref> <description>DB Connection</description> <res-ref-name>jdbc/xwiki</res-ref-name> <res-type>javax.sql.DataSource</res-type> <res-auth>Container</res-auth> </resource-ref> But this gave me the following error when, after deploying to Glassfish, i tried to go to http://localhost:8080/xwiki/bin/view/Main/ Glassfish logs contain the following two logs of this error: and also They seem to show that i need to use WEB-INF/hibernate.xml.cfg to set up the proper vendor Dialect So i modified WEB-INF/xwiki.cfg so to use the line: xwiki.store.hibernate.path=/WEB-INF/hibernate.cfg.xml Then, inside WEB-INF/hibernate.cfg.xml i ONLY uncommented the line <property name="dialect">org.hibernate.dialect.MySQLDialect</property> keeping all others (connection.username, connection.password ...) commented so to check that the ones provided by Glassfish are being used instead. After undeploying previous and deploying this modified version i get a different error when trying to visit http://localhost:8080/xwiki/bin/view/Main And in Glassfish logs: and seven more like this one (i truncated the whole stack) that match the errors in named queries reported above (listGroupsForUser, getSpaceDocsName,getAllUsers,getAllDocuments,getSpaces,getAllPublicDocuments and getAllSpaceDocuments) : This time the errors seem related to the searches themselves... I think that what might be happening is that Hibernate is not really configured to be using Glassfish datasource, but instead it expects to use the connection.username, connection.password, connection.driver_class, connection.pool_size ... properties defined in WEB-INF/hibernate.cfg.xml that i've commented out because i'd like to use Glassfish-configured datasource. I need help, so as to keep the properties that Hibernate reads from WEB-INF/hibernate.cfg.xml to a minimum and pointing it to Glassfish-defined JNDI resource instead. Thank you very much !
