+
+    * src/main/webapp/WEB-INF/config/struts-config.xml: 
+      Added two ActionMappings:
+      One for showing all FIS (ArtifactFactories) in an View.
+      The other for selceting one ArtifactFactory an visualizing the First Step of an Artifact. 
+    * src/main/webapp/WEB-INF/jsp/index.jsp Edited:
+      Added an Combobox for selecting an FIS 
+    * src/main/webapp/WEB-INF/web.xml: 
+      Added the Servletmapping for the Struts Framework
+    * src/main/java/de/intevation/gnv/action/SelectArtifactFactoryAction.java Added, 
+      src/main/java/de/intevation/gnv/action/FetchArtifactFactoriesAction.java Added, 
+      src/main/java/de/intevation/gnv/action/ArtifactDatabaseActionBase.java Edited: 
+      Some ActionHandler added for Handling the different Requests of the GNV.
+      FetchArtifactFactoriesAction: Will provides the Controllerlogic for Queriing all Reachable ArtifactFactories.
+      SelectArtifactFactoryAction will select one Specific ArtifactFactory and will create
+      an Instance in the ArtifactDatabase.
+    
+    * src/main/java/de/intevation/gnv/action/sessionmodel/DefaultSessionModel.java Added,: 
+      src/main/java/de/intevation/gnv/action/sessionmodel/SessionModelFactory.java Added,   
+      src/main/java/de/intevation/gnv/action/sessionmodel/SessionModel.java Added:
+      Interface and Defaultimplementation of an Model which can store the Session-Specific Informations.
+      e.g. Reachable ArtifactFactories and the current Artifact which should be used.
