2009-09-09	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* artifact-database/src/main/java/de/intevation/artifactdatabase/rest/CreateResource.java:
	New. Resource to create an artifact. Not working on artifact database yet.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/rest/RestApp.java:
	Attached create to web server.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/rest/FactoriesResource.java:
	Added meta data to Get annotation.

2009-09-09	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* artifact-database/pom.xml: Added dependency to restlet.ext.xml
	for XML handling in representations.

	* contrib/run.sh: Adjusted to fit new dependency.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/XMLUtils.java:
	New. Handle some boiler plate XML stuff. Move more stuff of this kind
	into this file.

	* TODO: Added remark to move more XML stuff into XMLUtils.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/rest/Standalone.java:
	Tell at startup on which port we are listing.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/rest/FactoriesResource.java:

2009-09-09	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* artifact-database/doc/artifactdb-example-conf.xml: removed
	* artifact-database/doc/example-conf/conf.xml: Re-added here.

	The configuration is now found in a subdirectory set by the
	system property 'artifact.database.dir'. If this property is
	not set '~/.artitactdb' is used. This directory should contain
	a file 'conf.xml' with the configuration details.
	  If the artifact database is started as a standalone the config
	directory is searched for 'log4j.properties' to configure the
	logging.
	  The H2 database is also search in this directory with the
	name 'artifacts.db' if the connection url in config.xml is
	not overwritten.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/Config.java:
	Refactored a bit to follow the new configuration policy.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/DBConnection.java:
	Build default connection url as described.

	* artifact-database/doc/example-conf/log4j.properties: New.
	example logging config

	Added some more logging infos.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/App.java:
	Load the log4j configuration at startup and starts a REST standalone web server.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/rest: New.
	Package for REST binding.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/rest/Standalone.java:
	Convenience wrapper to start a standalone REST web server.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/rest/RestApp.java:
	Concrete REST application. TODO: attach restlets to interact with artifact database.

	* contrib/run.sh: Little start script to launch artifact database for test
	purpose from classes without the need to build packages. 
	Background: The maven exec:exec goal does not work consistently for me (slt). 
	At home it does, at work it doe not. Anyway. Usage:

	$ ./contrib/run.sh \
	      -Dartifact.database.dir=artifact-database/doc/example-conf/ \
	      de.intevation.artifactdatabase.App

	artifact-database/src/main/java/de/intevation/artifactdatabase/DefaultArtifact.java,
	artifact-database/src/main/java/de/intevation/artifactdatabase/Config.java,
	artifact-database/src/main/java/de/intevation/artifactdatabase/FactoryBootstrap.java,

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:
	Wired together Backend, ArtifactDatabaseImpl and FactoryBootstrap.

2009-09-06	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* artifact-database/src/main/java/de/intevation/artifactdatabase/DBConnection.java:

2009-09-06	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* 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.

2009-09-04	Tim Englich	<tim.englich@intevation.de>

	* src/main/java/de/intevation/artifactdatabase/FactoryBootstrap.java (loa,

	configuration.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/DefaultArtifactContextFactory.java:
	New. Default implementation of ArtifactContextFactory. Creates a DefaultArtifactContext.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/DefaultArtifactContext.java:
	New. Default implementation of ArtifactContext.

	* artifact-database/src/main/java/de/intevation/artifactdatabase/FactoryBootstrap.java:
	New. Class to bootstrap the context and the artifact factories.

	* 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.

2009-09-04	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	* artifacts/src/main/java/de/intevation/artifacts/ArtifactContextFactory.java:
	New. Factory for a global context in the artifact data base. Useful to
	create shared ressources for artifacts like caches et al.

	* artifacts/src/main/java/de/intevation/artifacts/ArtifactDatabase.java,
	artifacts/src/main/java/de/intevation/artifacts/ArtifactFactory.java,
	artifacts/src/main/java/de/intevation/artifacts/ArtifactContextFactory.java,
	artifacts/src/main/java/de/intevation/artifacts/Artifact.java: Uses the
	global context more consistent.
