jboss 4.2.3 GA, java version "1.6.0_15", c3p0-0.9.1.2.jar, linux
I am trying to use c3p0 as only datasource and I want to get rid of hsqldb-ds
and mysql-ds.
c3p0-service.xml is default
| <server>
| <mbean code="com.mchange.v2.c3p0.jboss.C3P0PooledDataSource"
| name="jboss:service=PooledDS">
| <attribute name="JndiName">PooledDS</attribute>-->
| <attribute name="JdbcUrl">URL</attribute>
| <attribute name="DriverClass">com.mysql.jdbc.Driver</attribute>
| <attribute name="User">USER</attribute>
| <attribute name="Password">PWD</attribute>
| </mbean>
| </server>
|
I set ejb-deployer.xml - EJBTimerService to depend on this DS by change
| <depends optional-attribute name="DataSorce">
jboss.jca:service=DataSourceBinding,name=DefaultDS </depends>
|
to
| <depends>jboss.jca:service=DataSourceBinding,name=PooledDS</depends>
|
However I realize that c3p0 is not bound to jca, so I changed JNDI name of c3p0
bean to
| <mbean code="com.mchange.v2.c3p0.jboss.C3P0PooledDataSource"
| name="jboss.jca:service=DataSourceBinding,name=PooledDS">
|
This worked, but EJBTimerSerivce try look up DataSource with null:
| ObjectName: jboss.ejb:service=EJBTimerService,persistencePolicy=database
| State: FAILED
| Reason: java.sql.SQLException: Failed to lookup data source: null
| I Depend On:
| jboss.jca:service=DataSourceBinding,name=PooledDS
|
This look like that EJBTimerService do not receive any DS. Putting back
optional-argument=DataSource, helpd. Error message changed to:
| ObjectName: jboss.jca:service=DataSourceBinding,name=PooledDS
| State: NOTYETINSTALLED
| Depends On Me:
| jboss.ejb:service=EJBTimerService,persistencePolicy=database
|
I find out that I am not alone with this problem. For example in jboss forum

http://www.jboss.org/index.html?module=bb&op=viewtopic&p=3983368#3983368 [/url]
Which lead to inetersting solution
http://www.nabble.com/c3p0-vs-JPA-injections-on-JBoss-td23722441.html . This
helped me to fix EJBTimerService dependency on Pooled JNDI name.
I am just thinging is it possible to live completly without any -ds.xml data
source?
