Matthias Wuttke commented on SHALE-422: --------------------------------------- Creating an empty "WEB-INF/lib" folder solves the "symptoms" of this problems. > NullPointerException if no WEB-INF/lib > -------------------------------------- > > Key: SHALE-422 > URL: https://issues.apache.org/struts/browse/SHALE-422 > Project: Shale > Issue Type: Bug > Components: Tiger > Affects Versions: 1.0.4 > Environment: Eclipse 3.1 with Tomcat Launcher Plugin > Reporter: Matthias Wuttke > > I use the Sysdeo Tomcat Launcher Plugin together with the DevLoaderClasspath > extension in order to debug my application. Because this classpath extension > sets the classpath for Tomcat (including my Maven Repository classpath) I do > not need a WEB-INF/lib directory.
