Hi,
I need some help configuring Glassfish-managed DataSource for XWiki
Enterprise (stable 2.1.1).
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#HInstallinā¦
)
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/
HTTP Status 500 -
type Exception report
message
descriptionThe server encountered an internal error () that prevented
it from fulfilling this request.
exception

Wrapped Exception: Hibernate Dialect must be explicitly set
Glassfish logs contain the following two logs of this error:
53:44,236 [
http://localhost:8080/xwiki/bin/view/Main/]
WARN
UserSuppliedConnectionProvider - No connection properties specified -
the user must supply JDBC connections
and also
53:44,269 [
http://localhost:8080/xwiki/bin/view/Main/]
WARN
action.RequestProcessor - Unhandled Exception thrown: class
com.xpn.xwiki.XWikiException
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
HTTP Status 500 -
type Exception report
message

And in Glassfish logs:

WARN

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) :
19:05,013 [
http://localhost:8080/xwiki/bin/view/Main/]
ERROR
impl.SessionFactoryImpl - Error in named query: listGroupsForUser
org.hibernate.hql.ast.QuerySyntaxException: XWikiDocument is not mapped
[ select distinct doc.fullName from XWikiDocument as doc, BaseObject as
obj, StringProperty as prop where obj.name = doc.fullName and
obj.className='XWiki.XWikiGroups' and obj.id = prop.id.id and
prop.id.name='member' and (prop.value=:username or
prop.value=:shortname or prop.value=:veryshortname) ]
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 !
