+2009-09-14	Tim Englich	<tim.englich@intevation.de>
+
+	* src/main/java/de/intevation/artifacts/ArtifactFactory.java Edited:

+
+	* src/main/resources/sql/org-h2-driver.properties: 
+	Bug Fixed in SQL-Query
+
+2009-09-13	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	Refactored the persistent handling of the artifacts in the 
+	artifact database. When an artifact is called (describe, feed,
+	advance, out) a new CallContext is given instead of the
+	old Object context. CallContext.globalContext() returns the
+	old Object context now. CallContext.afterCall() may be
+	called from inside describe, feed, advance and out to tell
+	the artifact database what to do after the processing of
+	the specific call.
+	
+	The accepted values are:
+		- NOTHING    for doing nothing
+		- TOUCH      for just update the last access time
+		- STORE      for persisting the artifact.
+		- BACKGROUND to signal that the artifact has started
+		             a background operation.
+
+	After the background operation the artifact has to call
+	CallContext.fromBackground() to signal the artifact 
+	database that the artifact needs to be touched or stored.
+
+	!!! Without this call the artifact database assumes there
+	!!! is still some background operation on this artifact
+	!!! which prevents reclaiming resources
+
+	* artifacts/src/main/java/de/intevation/artifacts/CallContext.java:
+	New. New API to cope with background processing.
+
+	* artifacts/src/main/java/de/intevation/artifacts/Artifact.java:
+	Replaced old Object context with CallContext context.
+
+	* artifact-database/src/main/java/de/intevation/artifactdatabase/DefaultArtifact.java:
+	Adjusted.
+
+	* artifacts/src/main/java/de/intevation/artifacts/ArtifactDatabase.java:
+	For a better encapsulation of the persistence operations of the
+	artifacts the database does not return artifacts any more. It delegates
+	the describe, feed, advance and out call to internal structures.
+
+	* artifacts/src/main/java/de/intevation/artifacts/ArtifactDatabaseException.java:
+	New. Simplifies handling of error conditions inside of artifact database.
+
+	* artifact-database/src/main/java/de/intevation/artifactdatabase/ArtifactDatabaseImpl.java:
+	Adjusted to new interface. Internally it handles the background API.
+
+	* artifact-database/src/main/java/de/intevation/artifactdatabase/rest/ArtifactResource.java,
+	artifact-database/src/main/java/de/intevation/artifactdatabase/rest/FactoriesResource.java,
+	artifact-database/src/main/java/de/intevation/artifactdatabase/rest/OutRepresentation.java,
+	artifact-database/src/main/java/de/intevation/artifactdatabase/rest/CreateResource.java,
+	artifact-database/src/main/java/de/intevation/artifactdatabase/rest/ArtifactOutResource.java:
+	Adjusted to new artifact database interface (which greatly simplifies things)
+
+	* artifact-database/src/main/java/de/intevation/artifactdatabase/DatabaseCleaner.java:
+	Artifacts in background are not removed from database any longer.
+
+	* artifact-database/src/main/java/de/intevation/artifactdatabase/App.java: Little
+	re-wirering need for new cleanup.
+
+	* artifact-database/src/main/java/de/intevation/artifactdatabase/Backend.java: 
+	Simplified to do the SQL stuff only. The most infrastructure stuff is now done
+	in ArtifactDatabaseImpl.
+
+	* artifact-database/src/main/java/de/intevation/artifactdatabase/Id.java:
+	New. Helper base class to enable filtering of background artifacts by there
+	database id.
+
+	* artifact-database/src/main/resources/sql/org-h2-driver.properties:
+	Modified the INSERT statement to write the serialized artifact, too.
+
+2009-09-12	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	* artifacts/src/main/java/de/intevation/artifacts/Artifact.java(out):
+	out() is now called with an java.io.Outputstream to place
+	the output.
+
+	* artifact-database/src/main/java/de/intevation/artifactdatabase/DefaultArtifact.java,
+	artifact-database/src/main/java/de/intevation/artifactdatabase/Backend.java,
+	artifact-database/src/main/java/de/intevation/artifactdatabase/rest/OutRepresentation.java:
+	Adjusted.
+
+2009-09-11	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	* artifact-database/doc/example-conf/conf.xml: Added
+	sleep time for cleanup thread.
+
+	* artifact-database/src/main/java/de/intevation/artifactdatabase/App.java:
+	Start cleanup thread at startup.
+
+	* artifact-database/src/main/java/de/intevation/artifactdatabase/Backend.java:
+	Make artifact restoring bit more robust, added ref to
+	cleanup thread to do an immediate cleanup when dead artifact
+	is found by lookup.
+
+	* artifact-database/src/main/java/de/intevation/artifactdatabase/DatabaseCleaner.java:
+	New. The cleanup thread. It cleans up the artifact database
+	perodically and calls the endOfLife() methods of the dead
+	artifacts. Default cleanup interval is 5 minutes.
+
+	* artifact-database/src/main/resources/sql/org-h2-driver.properties:
+	Tuned SQL a bit to fetch only a 50 artifacts in search for
+	outdated artifacts to avoid too much memory consumption.
+
+	* contrib/run.sh: Little tweak to work with more than one
+	commons-pool version installed.
+
+	* TODO: Removed remarks about the now implemented killer 
+	thread and the moves XML stuff.
+
+	* README: Changed text how to create a H2 database from
+	command line only. XXX: This is still broken. The best
+	way to set up the database by now is to start the Console 
+	client, connect to the database, c&p the schema.sql 
+	into the SQL text area and execute it.
+
+2009-09-10	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

+2009-09-07  Tim Englich  <tim.englich@intevation.de>
+
+	* src/main/java/de/intevation/artifactdatabase/FactoryBootstrap.java: edited
+	Bug fixed in XPath Expression. Now the Nodes and not the Text of the Nodes will
+	be used instantiating the ArtifactFactory.

+2009-09-07	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	* artifact-database/src/main/java/de/intevation/artifactdatabase/Backend.java:
+	Implemented loading of artifacts from database. If the last access of an 
+	artifact is too long ago for its time to life, null is returned.
+
+	* TODO: Added remark to implement a "killer" thread which periodically cleans the
+	database from outdated artifacts and calls the endOfLife() method on those.

+2009-09-07	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	* artifact-database/src/main/java/de/intevation/artifactdatabase/SQL.java:
+	Properties wrapper for SQL statements. The properties are looked up
+	in resorces /sql/DRIVER.properties (DRIVER is the name of the db driver class,
+	lowercased and '.' replaced by '-'. 'org.h2.Driver' turns to
+	'org-h2-driver.properties', e.g.
+
+	* artifact-database/src/main/resources/sql/org-h2-driver.properties:
+	SQL statements for H2 database.
+
+	* artifact-database/src/main/java/de/intevation/artifactdatabase/Backend.java:
+	Artifacts are proxies/wrapped by an special Artifact implementation
+	to bound db activities transparentely to the Artifact. XXX: It has
+	to be evaluated if a more direct concept like extending the Artifact API
+	to store itself would be more robust for future implementations.
+	TODO: Loading Artifact from db is not implemented yet.
+
+2009-09-06	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	* artifact-database/src/main/java/de/intevation/artifactdatabase/Backend.java:
+	New. Used to wrap database presentations of artifacts into artifacts.
+
+	* artifact-database/src/main/java/de/intevation/artifactdatabase/ArtifactDatabaseImpl.java:
+	New. Implements a ArtifactDatabase backed by Backend.
+
+	* artifact-database/src/main/java/de/intevation/artifactdatabase/Config.java:
+	Removed empty last line.
+	
+	* artifact-database/src/main/java/de/intevation/artifactdatabase/App.java:

+
+	* artifacts/src/main/java/de/intevation/artifacts/Artifact.java(setup):
+	Added the setup() method to have symmetric counter part to endOfLife().
+
+	* artifacts/src/main/java/de/intevation/artifacts/ArtifactFactory.java(timeToLiveUntouched):
+	Added this method to let the factory decide how long an artifact should live in ms.
+	This is not a part of the Artifact itself because this is only evaluated once when
+	the artifact is created.
+
+	* artifact-database/src/main/java/de/intevation/artifactdatabase/DefaultArtifact.java:
+	New. Simple base class implementation of the Artifact interface.
+
+	* artifact-database/src/main/java/de/intevation/artifactdatabase/DefaultArtifactFactory.java:
+	New. Simple base class implementation of the ArtifactFactory interface. When setup()
+	on instances of this class is called, it pull ttl, name, description and
+	the artifact class name from the node given. See artifactdb-example-conf.xml
+	for examples.
+
+	* artifact-database/pom.xml: Cleaned up XML. 
+	Introduced dependency to apache commons dbcp, used for pooling of the 
+	database connections to artifact db. 
+	Added parameters for the exec:exec goal to make the project
+	startable without building packages.
+
+	* artifact-database/doc/schema.sql: Removed AUTO_INCREMENT from primary key
+	to avoid compatibility issues with other non-H2 databases (PostgreSQL, Oracle, ...)
+	which have no or limited support for generated keys in the JDBC driver. Now
+	using an explicit sequence. TTL ist now big int to bring the resolution to ms.
+
+	* artifact-database/src/main/java/de/intevation/artifactdatabase/Config.java:
+	Refactored a bit to make the XPath access function usable on arbitrary XML
+	documents and parts of.
+
+	* artifact-database/src/main/java/de/intevation/artifactdatabase/DBConnection.java:
+	New. Exposes DataSource from a apache dbcp connection pool configured by the
+	global configuration file. See artifactdb-example-conf.xml for examples.
+	TODO: Write some documentation about this.
+
+	* artifact-database/doc/artifactdb-example-conf.xml: Adjusted to be a more realistic
+	example config file. Added references to DefaultArtifact/DefaultArtifactFactory and
+	demonstrate how to configure the connection pool.
+
+	* TODO: Add remark to document the connection file.
+
+	* artifact-database/src/main/java/de/intevation/artifactdatabase/FactoryBootstrap.java:
+	Do not crash when config does not contain any factories.
+
+2009-09-04	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	* artifact-database/src/main/java/de/intevation/artifactdatabase/Config.java (getNodeXPath):
+	New method to get a single node from configuration.
+
+	* artifacts/src/main/java/de/intevation/artifacts/Artifact.java (endOfLife):
+	New method called when artifact is going to be removed from artifact data base.

+	* artifact-database/src/main/java/de/intevation/artifactdatabase/App.java: Bootstrap
+	factories.
+
+	* artifact-database/src/main/java/de/intevation/artifactdatabase/Config.java: New.
+	Loads configuration as XML from a file. The file is specified by the system
+	property "artifact.database.config" and defaults to "artifactdb-conf.xml".
+	The configuration can be searched via XPath.
+
+	* artifact-database/pom.xml: Made de.intevation.artifactdatabase.App the main
+	class for start up.
+
+	* TODO: Added remark to add logging to artifact database.
