PDI logging in biserver

Hi All,

I am stuck with a new Installation of biserver-ce (5.4.0.0-128). I am trying to execute a PDI Job stored in a rdbms repository, but somehow it fails while connecting to the PDI repository. My question however is quite general:

How do I get to see the output of log messages of the form

if ( log.isDetailed() ) {
log.logDetailed( "New database connection defined" );
}

in any of the biserver logfiles?

(e.g. from org.pentaho.di.core.database.Database.java)

I tried fiddling with log4j.xml, logging.properties and settings in xaction file without success plus I did quite a bit of searching. All without success. Now turning to the forum for help.

Thanks,
Markus
