+## Adding a shared GWT library bundle
+
+Sometimes we need a bundle containing code and resources which can be used by other GWT bundles (GWT library).
+To create and use such a bundle from another GWT bundle (e.g. com.sap.sailing.gwt.ui) some additional steps compared to the normal Java bundle creation are required.
+
+GWT library bundle project creation
+* Add a new Java plugin project, using <git-workspace>/java/<bundle-name> as the project directory
+* Add the GWT-SDK dependency to the project 
+* Add a GWT module file to project (ModuleName.gwt.xml)
+* Add the bundle to the main pom.xml in /git/java
+
+Use the GWT library project in a GWT UI project
+* Add the src folder of the GWT library bundle to classpath of all GWT-Launch configurations (required to let the GWT dev mode find the sources of java classes) -> Open GWT launch config, select tab 'classpath', select 'User entries', click 'Advanced' button, choose 'add folders' option and add the src folder of the GWT library project
+* Add the bundle the pom.xml of the GWT UI project (for the maven build)
