+
+	* src/main/java/de/intevation/flys/client/server/MapPrintServiceImpl.java:
+	  Call MapFish print via Apache Commons Http Client to re-establish
+	  LGPL conformance.
+
+	* src/main/webapp/WEB-INF/web.xml: Configured the MapFish Print servlet
+	  again. You need to adjust the init parameter 'print-url' of the 
+	  servlet MapPrintService to point to the MapFish Print servlet.
+
+	* pom.xml: Added dependency to Apache Commons Http Client 3.1
