Improve log messages when using an UDAF without the required classes defined in VDB ----------------------------------------------------------------------------------- Key: TEIID-4756 URL: https://issues.jboss.org/browse/TEIID-4756 Project: Teiid Issue Type: Enhancement Components: Server Affects Versions: 9.1.2 Environment: * WildFly 10 * Teiid 9.1.2 * CentOs 7 Reporter: Pedro Inácio Assignee: Steven Hawkins When using an _UDAF_ in a _VDB_, the required *JAVA_CLASS* and *JAVA_METHOD* are specified in the _VDB_. When for some reason the _JAVA_CLASS_ or _JAVA_METHOD_ do not exist in the library, the message from the system is quite imperceptible. In the following log excerpt, _GlobalTitleRangeCheck_ class does not exist in the _jar_ _rangecreator_. The model name that is defining the _VIRTUAL FUNCTION_ is _RangeGroupConcat_. The _VDB_ name is _CountryServiceListVDB_. {panel:title=Log excerpt} DEBUG [org.teiid.RUNTIME] (Worker53_async-teiid-threads203) TEIID50104 VDB CountryServiceListVDB.1 model "RangeGroupConcat" Using translator null and connection null to load metadata. ... INFO [org.teiid.RUNTIME] (Worker53_async-teiid-threads203) TEIID40073 The metadata for the VDB CountryServiceListVDB.1 is loaded, however it is not valid. Check models for errors. Correct the metadata and re-deploy. INFO [org.teiid.RUNTIME.VDBLifeCycleListener] (Worker53_async-teiid-threads203) TEIID40003 VDB CountryServiceListVDB.1 is set to FAILED {panel} As observed from the log excerpt, the only possible hint to know what the problem is with the _FAILED_ deploy might be: _model "RangeGroupConcat" Using translator null and connection null to load metadata._ But this is a normal logging message that doesn't have nothing to do with the real problem. When putting the entire system logging _ALL_ levels, then is easy to see what the problem is: {panel:title=Log excerpt} DEBUG [org.teiid.RUNTIME] (Worker52_async-teiid-threads202) TEIID50104 VDB CountryServiceListVDB.1 model "RangeGroupConcat" Using translator null and connection null to load metadata.
