Nullpointer occurs using the Stream Database operator
Hello
I want to use the Stream Database operator and get the following Error-log
Mar 21, 2012 12:04:54 AM CONFIG: Connecting to jdbc:postgresql://localhost:5432/postgres as postgres.
Mar 21, 2012 12:04:54 AM SEVERE: Process failed: operator cannot be executed. Check the log messages...
Mar 21, 2012 12:04:54 AM SEVERE: Here: Process[1] (Process)
subprocess 'Main Process'
==> +- Stream Database[1] (Stream Database)
Mar 21, 2012 12:04:54 AM SEVERE: java.lang.NullPointerException
Working on a 64bit-machine with Linux and 64bit JDK 1,6
No clue about the RapidMiner-architekture i use. its the "Other systems"-version.
At work - using Win7 i get same error.
Sometimes the error only appears wile using rapidminer on the Database - host (using the local database)
the Read Database operator works without any error
Any ideas?
