	  src/main/java/de/intevation/gnv/geobackend/base/connectionpool/ConnectionPoolFactory.java (initializeConnectionPool): 
	  Removed Encodingerrors from listed Files. All Files are now UTF-8 compliant.

2010-01-05  Tim Englich  <tim.englich@intevation.de>

	* src/main/java/de/intevation/gnv/geobackend/sde/datasources/RasterObject.java:
	  Made it serializable to be cachable beyond reboot.

2010-01-05  Tim Englich  <tim.englich@intevation.de>

	* src/main/java/de/intevation/gnv/geobackend/sde/datasources/ArcSDEStatement.java (handleResultSet): 
	  Switched to return the RasterObject instead of the depth in an Rasterquery.
	  This should help to get a better performance.
	* src/main/java/de/intevation/gnv/geobackend/sde/datasources/RasterObject.java (RasterObject): 
	  Added new Object for Caching Rastertiles and all Informations that are
	  required for calculating the Depth to a given Coordinate.

2010-01-04  Tim Englich  <tim.englich@intevation.de>

	* src/main/java/de/intevation/gnv/geobackend/sde/datasources/ArcSDEStatement.java (handleResultSet): 
	  Added Rasterdatasupport to the ARCSDESTATEMENT.
	  Now it is possible to Query the Value of an Pixel like that:
	  SELECT ST_ASTEXT(RASTER) FROM MEDIAN.TOPO_BS_D_6X10SEC where INTERSECTS(RASTER, "POINT( 12.084721594184593 54.35583351483295)")

2009-12-19	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* contrib/sql-cache.xml: Configured disk storage to survive restarts.

	* src/main/java/de/intevation/gnv/geobackend/base/query/QueryExecutorFactory.java:
	  Added explicit shutdown hook.

	* src/main/java/de/intevation/gnv/geobackend/base/query/CachingQueryExecutorFactory.java:
	  Fixed spelling of cacheResults() which prevented results to be stored in cache.
	  Added some logging.

2009-12-18	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	Experimental caching of SQL results via Ehcache

	* pom.xml: Added dependency to Ehcache

	* src/main/java/de/intevation/gnv/geobackend/base/query/QueryExecutor.java:
	  Extended interface to support caching by SQL statements as Strings.

	* src/main/java/de/intevation/gnv/geobackend/base/query/QueryExecutorBase.java:
	  Implements new interface with no caching
	
	* src/main/java/de/intevation/gnv/geobackend/base/query/container/QueryContainerFactory.java:
	  synchronized access to singleton.

	* src/main/java/de/intevation/gnv/geobackend/base/query/DefaultQueryExceutor.java:
	  calls caching methods of base class.

	* src/main/java/de/intevation/gnv/geobackend/base/query/QueryExecutorFactory.java:
	  When system property 'query.executor.factory' is given the value is used as
	  a class name to be instantiated as a sub class of QueryExecutorFactory.
	  This happens if the singleton of QueryExecutorFactory is created. With the
	  mechanism it is possible to replace the standard behavior of creating QueryExecutors.

	* src/main/java/de/intevation/gnv/geobackend/base/query/CachingQueryExecutorFactory.java:
	  New: This class extends QueryExecutorFactory and can be used as replacement for
	  the standard QueryExecutorFactory. Usage: 

	  -Dquery.executor.factory=de.intevation.gnv.geobackend.base.query.CachingQueryExecutorFactory

	  If you pass in another system property 'caching.query.executor.config' you can
	  customize the caching. The value is used as a file name to an XML file with 
	  Ehcache configuration.

	* contrib/sql-cache.xml: Demo configuration for sql caching. Usage:

	  -Dquery.executor.factory=de.intevation.gnv.geobackend.base.query.CachingQueryExecutorFactory
	  -Dcaching.query.executor.config=contrib/sql-cache.xml
