+
+	* src/main/webapp/scripts/viewport.jsp: 
+	  Put the bboxx from the mapservice-object and write it to an 
+	  javascript-variable. This variable will be used to center the map to
+	  the extend of the data which should be visualized.
+
+	* src/main/java/de/intevation/gnv/artifactdatabase/objects/map/DefaultMapService.java (getBBoxValue),
+	  src/main/java/de/intevation/gnv/artifactdatabase/objects/map/MapService.java (getBBoxValue):
+	  Added a method for getting the bbox as a string from the mapservice-object.
+
+	* src/main/java/de/intevation/gnv/action/WMSAction.java (execute):
+	  Read the bbox from the retrieved meta-document and out it into the 
+	  mapservice-object which is used to represent the WMS in the client.
