On my karaf 4.0.8 I've installed the feature pax-jdbc-postgresql. The DataFactory for PostgreSQL is installed:
org.osgi.service.jdbc.DataSourceFactory]
osgi.jdbc.driver.class org.postgresql.Driver
osgi.jdbc.driver.name PostgreSQL JDBC Driver
osgi.jdbc.driver.version PostgreSQL 9.4 JDBC4.1 (build 1203)
service.bundleid 204
service.scope singleton
Using Bundles com.eclipsesource.jaxrs.publisher (184)
I've create the file etc/org.ops4j.datasource-psql-sandbox.cfg:
osgi.jdbc.driver.class=org.postgresql.Driver
osgi.jdbc.driver.name=PostgreSQL
url=jdbc:postgresql://localhost:5432/sandbox
dataSourceName=psql-sandbox
user=sandbox
password=sandbox
After that, I see the confirmation in karaf.log that the file was processed:
2017-02-10 14:54:17,468 | INFO | 41-88b277ae0921) | DataSourceRegistration | 154 - org.ops4j.pax.jdbc.config - 0.9.0 | Detected config for DataSource psql-sandbox. Tracking DSF with filter (&(objectClass=org.osgi.service.jdbc.DataSourceFactory)(osgi.jdbc.driver.class=org.postgresql.Driver)(osgi.jdbc.driver.name=PostgreSQL))
However, I see no new DataSource in services list in console. What went wrong? I see no exceptions in log ....
The log message tell you that the config was processed and it is now searching for a suitable DataSourceFactory OSGi service.
The problem in your case is that it does not find such a service. So to debug this you should list all DataSourceFactory services and check their properties.
service:list DataSourceFactory
In my case it shows this:
[org.osgi.service.jdbc.DataSourceFactory]
-----------------------------------------
osgi.jdbc.driver.class = org.postgresql.Driver
osgi.jdbc.driver.name = PostgreSQL JDBC Driver
...
As you see it does not match the filter you see in the log. Generally you should only provide either osgi.jdbc.driver.class or osgi.jdbc.driver.name not both. If you remove the osgi.jdbc.driver.name line the config will work.
There is no error message as the system can not know if the error is transient or not. Basically as soon as you install a matching OSGi service the DataSource will be created.
