	* src/main/java/de/intevation/flys/artifacts/model/SessionHolder.java:
	  Bugfix: Call correct method to retrieve an instance of
	  SessionFactoryProvider.

2011-04-14	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/model/SessionHolder.java:
	  New. Contains thread local session holder for hibernate sessions.
	* src/main/java/de/intevation/flys/artifacts/model/RiverFactory.java:
	  Uses session from SessionHolder.

	* src/main/java/de/intevation/flys/artifacts/context/SessionCallContextListener.java:
	  Interacts with SessionHolder now.
	
	* src/main/java/de/intevation/flys/exports/ChartExportHelper.java:
	  Removed superfluous import.
	
2011-04-14  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/context/SessionCallContextListener.java:
	  Implementation of a CallContext.Listener to open/close Hibernate
	  Sessions for each request.

2011-04-14  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/WINFOArtifact.java,
	  src/main/java/de/intevation/flys/artifacts/states/DefaultState.java:
	  Some modifications related to the last commit - modification of the
	  describe() signature of a State.

2011-04-14  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/states/GaugeSelect.java:
	  Removed. We do not need a state to select a gauge - the selection takes
	  place by choosing a start and an end point.

2011-04-13  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/states/RiverSelect.java:
	  Bugfix: added missing label node to root node and a namespace to the
	  data node.

2011-04-12  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/WINFOArtifact.java:
	  The name of the artifact 'winfo' is written into the DESCRIBE document
	  now. We need this to have a proper way to distinguish between different
	  artifacts in the UI.

2011-04-12  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/WINFOArtifact.java: Bugfix:
	  States are filled with data before they describe themself.

2011-04-11  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/model/AnnotationsFactory.java:
	  New. A factory that returns the annotations of a specific river.

	* src/main/java/de/intevation/flys/artifacts/services/DistanceInfoService.java:
	  New. This service provides a document that contains information about
	  distances of a river.

	* doc/conf/conf.xml: Registered the DistanceInfoService.

2011-04-06  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/collections/FLYSArtifactCollection.java:
	  This collection overrides the out() operation now. The incoming request
	  document is read and the related OutGenerator is used to create the
	  output.

	* src/main/java/de/intevation/flys/artifacts/WINFOArtifact.java: Removed
	  the code to create discharge curves. It has moved to the
	  DischargeCurveGenerator which now does this work.

2011-04-06  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/exports/OutGenerator.java: The
	  generate() method throws an IOException now.

	* src/main/java/de/intevation/flys/exports/DischargeCurveGenerator.java:
	  New. This OutGenerator creates discharge curves.

2011-04-06  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/FLYSArtifact.java: Changed
	  the visibility of the getData() method. It's now public, because the
	  OutGenerator needs an artifact's data.

2011-04-03	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* src/**/*.java: Removed trailing whitespace.

2011-04-03	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/collections/FLYSArtifactCollection.java:
	  Make project compilable again by
	  commenting out a not existing XMLDebug reference.

2011-03-31  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/context/FLYSContextFactory.java:
	  Added code to parse the configured OutGenerators and to save them (in a
	  map) in the FLYSContext.

	* src/main/java/de/intevation/flys/artifacts/context/FLYSContext.java:
	  Added a key that is used to save the OutGenerators Map in the context.

2011-03-31  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/exports/OutGenerator.java:
	  New. This interface is used to generator different types of output.
	  ArtifactCollections will make use of this interface to create a
	  collected output of all its artifacts.

2011-03-30  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/collections/FLYSArtifactCollection.java:
	  Removed the Backend from FLYSArtifactCollection - used ArtifactDatabase
	  operations instead.

	* TODO: Removed 'remove Backend reference' TODO.

2011-03-30  Ingo Weinzierl <ingo@intevation.de>

	* doc/conf/artifacts/winfo.xml: Enhanced the configuration of the
	  discharge curve output mode. This output now provides three facets - W,
	  Q and the curve itself.

2011-03-30  Ingo Weinzierl <ingo@intevation.de>

	Tagged RELEASE 0.1

2011-03-30  Ingo Weinzierl <ingo@intevation.de>

	* doc/conf/artifacts/winfo.xml: Renamed an output mode in the WINFO
	  artifact configuration.

2011-03-29  Ingo Weinzierl <ingo@intevation.de>

	* src/main/resources/messages_de_DE.properties,
	  src/main/resources/messages_de.properties: Changed a german string.

2011-03-29  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/states/CalculationSelect.java:
	  Modified the available calculation modes and its order in the DESCRIBE
	  document.

	  src/main/resources/messages_de_DE.properties,
	  src/main/resources/messages_en.properties,
	  src/main/resources/messages_de.properties: Adapted the names of
	  calculation modes.

2011-03-28  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/collections/FLYSArtifactCollection.java:
	  Added the hash code of an artifact to the artifact part of the
	  collection's DESCRIBE document.

2011-03-28  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/WINFOArtifact.java: Changed
	  the background color of discharge curves to white.

2011-03-28	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/model/DischargeTables.java:
	  Cache the scale, too. Otherwise two calls to getValues() with
	  different arguments will result in the same output.

2011-03-28  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/model/DischargeTables.java:
	  Introduced a 'scale' parameter in the getValues() method.

	* src/main/java/de/intevation/flys/artifacts/WINFOArtifact.java: Filled
	  the out() operation with code that draws a discharge table of one or
	  more gauges specified by the given range in entered in a previous state.

2011-03-28  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/exports/ChartExportHelper.java:
	  New. A helper class to exports charts.

	* pom.xml: Added dependencies to iText, Batik and JFreeChart.

2011-03-28	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/importer/PegelGltParser.java:
	  Fixed swap of operands.

2011-03-28	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/model/GaugesFactory.java:
	  New. Load gauges for a river and filter them for given
	  ranges.

2011-03-25	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/model/DischargeTables.java:
	  Store data in a double [][] instead of interleaved double []
	  to be compatible with org.jfree.data.xy.DefaultXYDataset.

2011-03-25  Ingo Weinzierl <ingo@intevation.de>

	* TODO: Removed 'i18n' and 'step-back' TODOs and added an issue to remove
	  the Backend reference from FLYSArtifactCollection.

2011-03-25  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/collections/FLYSArtifactCollection.java:
	  Added missing artifact namespace of an attribute in the DESCRIBE
	  document.

2011-03-24  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/collections/FLYSArtifactCollection.java:
	  New. This ArtifactCollection overrides the DefaultArtifactCollection to
	  implement FLYS specific describe() and out() operations.

	* doc/conf/conf.xml: Use the FLYSArtifactCollection instead of the
	  DefaultArtifactCollection for this application.

2011-03-24	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/model/DischargeTables.java:
	  New. Fetches values of discharge tables in form of packed
	  w/q double arrays for given gauges.

	* src/main/java/de/intevation/flys/artifacts/model/RiverFactory.java:
	  Removed needless import.

2011-03-24  Ingo Weinzierl <ingo@intevation.de>

	* src/main/resources/messages_de_DE.properties: Added a german resource
	  bundle to avoid exceptions in the flys artifacts. Sometimes, the
	  Resources class is not able to find a 'de_DE' bundle and throws an
	  exception. This is really strange, because it should use the 'de' bundle
	  in that case, but it doesn't.

2011-03-23  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/WINFOArtifact.java: Added
	  some code to append the output modes of previous states to the DESCRIBE
	  document.

	  TODO: Determine if the current state is already filled with data and
	  append its output modes as well!

2011-03-22  Ingo Weinzierl <ingo@intevation.de>

	* doc/conf/artifacts/winfo.xml: Enhanced the location_distance state with
	  an output mode 'discharge_table'.

2011-03-21  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/states/DefaultState.java:
	  Write human readable strings as label attribute into the DESCRIBE
	  output. Those labels are used to be displayed in the GUI.

2011-03-21  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/states/CalculationSelect.java:
	  Added some further calculation types.

	* src/main/resources/messages.properties,
	  src/main/resources/messages_en.properties,
	  src/main/resources/messages_de.properties: Added i18n strings for the
	  calculation types

2011-03-21  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/FLYSArtifact.java:
	  Implemented the step-back part of the advance() operation.

2011-03-21  Ingo Weinzierl <ingo@intevation.de>

	* src/main/resources/messages_de.properties: Fixed a german umlaut.

2011-03-18  Ingo Weinzierl <ingo@intevation.de>

	* doc/conf/artifacts/winfo.xml: Added new states for entering a
	  location/distance and w/q.

	* src/main/resources/messages.properties,
	  src/main/resources/messages_en.properties,
	  src/main/resources/messages_de.properties: New string for the
	  location/distance and w/q input states.

2011-03-18  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/states/WQSelect.java:
	  New. A state for the W/Q input of the WINFO parameterization.

2011-03-18  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/states/DefaultState.java:
	  Append an attribute 'uiprovider' to the dynamic UI node.

	* src/main/java/de/intevation/flys/artifacts/states/LocationDistanceSelect.java:
	  New. A state for the location/distance selection of the WINFO
	  parameterization.

2011-03-17  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/states/DefaultState.java:
	  Added a new method getUIProvider() that might be overriden by concreted
	  subclasses that should be rendered with a specific UIProvider.

2011-03-17  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/WINFOArtifact.java:
	  The static UI part is created by the previous states now. This makes it
	  possible to group the data objects (which is necessary to group the
	  objects in the ui).

	* src/main/java/de/intevation/flys/artifacts/states/DefaultState.java:
	  Added a describeStatic() method that creates a node that contains the
	  data of that state.

2011-03-17  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/services/RiverService.java:
	  Removed TODO: the document contains the rivers provided by the backend
	  now.

2011-03-17	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* pom.xml: Added dependency to flys backend.

	* src/main/java/de/intevation/flys/artifacts/model/River.java:
	  Removed. We are using the backend model now.

	* src/main/java/de/intevation/flys/artifacts/model/RiverFactory.java:
	  Fetches the rivers from the backend.

	* src/main/java/de/intevation/flys/artifacts/states/RiverSelect.java:
	  Import fixes.

2011-03-15	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* doc/conf/conf.xml: Added section for database backend configuration.

2011-03-15	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/context/FLYSContextFactory.java:
	  Fixed build error coming from different import of XMLUtils.

2011-03-14  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/states/DefaultState.java:
	  Appended the missing label node that contains the human readable name of
	  the data item.

2011-03-14  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/WINFOArtifact.java,
	  src/main/java/de/intevation/flys/artifacts/states/DefaultState.java:
	  I18N of strings for the DESCRIBE document.

	* src/main/resources/messages.properties,
	  src/main/resources/messages_en.properties,
	  src/main/resources/messages_de.properties: I18N strings for the
	  calculcation mode state.

2011-03-14  Ingo Weinzierl <ingo@intevation.de>

	* doc/conf/artifacts/winfo.xml: Modified the winfo states.

	* src/main/java/de/intevation/flys/artifacts/WINFOArtifact.java: Adapted
	  the artifact regarding the changes of the last commit. The states
	  describe() method creates the dynamic UI node - the artifact needs to
	  apply this node.

	* src/main/java/de/intevation/flys/artifacts/states/CalculationSelect.java:
	  New. The state for choosing the calculation mode.

	* src/main/resources/messages.properties,
	  src/main/resources/messages_en.properties,
	  src/main/resources/messages_de.properties: Added i18n strings for the
	  calculation mode state.

2011-03-14  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/states/DefaultState.java:
	  New. This is the base state for the FLYS application. It provides a
	  method that creates the dynamic ui node for the DESCRIBE.

	* src/main/java/de/intevation/flys/artifacts/states/RiverSelect.java,
	  src/main/java/de/intevation/flys/artifacts/states/GaugeSelect.java: Both
	  classes extend the abstract base class DefaultState.

2011-03-14  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/resources/Resources.java:
	  New. This class retrieves the i18n strings from a ResourceBundle.

	* src/main/resources/messages.properties,
	  src/main/resources/messages_en.properties,
	  src/main/resources/messages_de.properties: Resource files for german and
	  english translation.

2011-03-10  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/WINFOArtifact.java: Appended
	  the data that have been inserted in former states into the static node
	  of the DESCRIBE.

2011-03-10  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/FLYSArtifact.java: The
	  operations feed() and advance() return the description of the artifact
	  using the describe() operation. This avoids additional server round trips
	  in the client - the clients gets to know about the new state of the
	  artifact immediately.

2011-03-10  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/FLYSArtifact.java:
	  Implemented a part (step forward) of the advance operation.

	* TODO: Implement Step-Back in advance operation.

2011-03-09  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/WINFOArtifact.java:
	  Implemented the abstract method getName(). It returns the constant
	  'winfo' string.

	* src/main/java/de/intevation/flys/artifacts/FLYSArtifact.java:
	  Implemented the feed action. The data of an incoming feed() operation is
	  stored in StateData objects that are saved in a map in the artifact.

	  NOTE: There is no input validation and no i18n of error messages (see
	  TODO).

2011-03-09  Ingo Weinzierl <ingo@intevation.de>

	* TODO: This file contains some open points that need to be done.

2011-03-09  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/FLYSArtifact.java: New. This
	  artifact serves as the default artifact for the FLYS application.

	* src/main/java/de/intevation/flys/artifacts/WINFOArtifact.java: This
	  artifact now inherits from FLYSArtifact. Furthermore, there is one big
	  change: we don't store the State objects itself in the artifact, but
	  just the identifier of those. This makes the artifact smaller and more
	  compatible agains previous versions of the software.

2011-03-08  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/services/RiverService.java:
	  New. This service will retrieve a list of provided rivers.

	* doc/conf/conf.xml: Added a configuration for the RiverService.

2011-03-07  Ingo Weinzierl <ingo@intevation.de>

	* doc/conf/conf.xml: Added a section user-factory and collection-factory in
	  the factories part of the configuration.

2011-03-01  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/states/RiverSelect.java:
	  Replaced the 'special' attribute from DESCRIBE with a 'uiprovider'
	  attribute.

2011-02-08  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/WINFOArtifact.java: The
	  RiverSelect state is called to create the UI part of the describe
	  document.

	* src/main/java/de/intevation/flys/artifacts/states/RiverSelect.java:
	  Implemented the dynamic UI part of describe(). The static part is not
	  inserted into the describe document at the moment. We need a reference to
	  the previous states for this.

2011-02-08  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/model/RiverFactory.java,
	  src/main/java/de/intevation/flys/artifacts/model/River.java: New. A model
	  class that represents a river and its factory to create concrete river
	  instances.
	  NOTE: Currently, this is just a mockup. The factory just returns two
	  static rivers "Mosel" and "Saar" without a connection to a backend.

2011-02-07  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/states/StateFactory.java: The
	  input data of a state is initialized with empty StateData objects after
	  the State has been created.

	* doc/conf/artifacts/winfo.xml: Renamed the input data nodes of the states
	  which now fits better to the class name of the implementation.

2011-02-07  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/WINFOArtifact.java: The
	  describe document returned by this artifact now contains the current state
	  and the reachable states.

2011-02-07  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/context/FLYSContextFactory.java:
	  The transitions are put into the TransitionEngine with the ID of the state
	  - not longer with the artifact name. On this way, we are able to fetch
	  just the transitions for a specific state, instead of all the transitions
	  of an artifact.

2011-02-04  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/WINFOArtifact.java: Describe()
	  returns the artifact's uuid and hash value. The whole implementation of
	  describe() is still outstanding.

2011-02-04  Ingo Weinzierl <ingo@intevation.de>

	* doc/conf/artifacts/winfo.xml: Removed useless config stuff.

	* src/main/java/de/intevation/flys/artifacts/WINFOArtifact.java: Removed
	  useless methods, and improved the init process - the first state is set as
	  the current state for this artifact.

	* src/main/java/de/intevation/flys/artifacts/states/RiverSelect.java,
	  src/main/java/de/intevation/flys/artifacts/states/GaugeSelect.java: New.
	  The states are used in the first two steps of the WINFOArtifact.
	  Currently, they just implement stubs of the necessary methods setup() and
	  describe().

2011-02-04  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/states/State.java,
	  src/main/java/de/intevation/flys/artifacts/transitions/TransitionEngine.java,
	  src/main/java/de/intevation/flys/artifacts/transitions/Transition.java:
	  Removed. These classes are placed in the artifact-database now.

	* src/main/java/de/intevation/flys/artifacts/transitions/DefaultTransition.java,
	  src/main/java/de/intevation/flys/artifacts/transitions/TransitionFactory.java:
	  Adapted imports of Transition.

	* src/main/java/de/intevation/flys/artifacts/states/StateFactory.java: New.
	  This factory should be used to create concrete State objects.

	* src/main/java/de/intevation/flys/artifacts/context/FLYSContext.java: Added
	  a constant key to store the StateEngine in the context.

	* src/main/java/de/intevation/flys/artifacts/context/FLYSContextFactory.java:
	  New method that initializes the states at application start.

2011-02-03  Ingo Weinzierl <ingo@intevation.de>

	* src/main/java/de/intevation/flys/artifacts/states/State.java: New. The
	  interface description of a state.

	* src/main/java/de/intevation/flys/artifacts/transitions/Transition.java,
	  src/main/java/de/intevation/flys/artifacts/transitions/DefaultTransition.java:
	  New. The interface description and a default implementation of a
	  transition.

	* src/main/java/de/intevation/flys/artifacts/transitions/TransitionEngine.java:
	  New. The TransitionEngine stores all transitions for each artifact and
	  should be used to determine, if an artifact can advance from one state to
	  another.

	* src/main/java/de/intevation/flys/artifacts/transitions/TransitionFactory.java:
	  New. Transitions should be created by using this class.

	* src/main/java/de/intevation/flys/artifacts/context/FLYSContext.java: New.
