+	* src/main/java/de/intevation/gnv/artifactdatabase/client/DefaultArtifactDatabaseClient.java (publishWMS),
+	  src/main/java/de/intevation/gnv/artifactdatabase/client/ArtifactDatabaseClient.java (publishWMS),
+	  src/main/java/de/intevation/gnv/action/WMSAction.java (execute): 
+	  Improved ExceptionHandling during WMS-Publishing.
+	  The responsedocument will be scanned for Exceptionreports.
+	  Also if no URL, Mapfile or Layer was retrieved from the Responsedocument 
+	  the Exceptionpage will be visualized instead an corrupt Openlayersclient.
