Antwort: Setting up Pluto unit tests to run under Eclipse

[Nico Max]

Hi,

my first guess is that the inputstream object might be NULL which in turn leads to further NPEs inside Castor.

Make sure that the 'portlet.xml' is on the classpath at runtime. The simplest way to achieve this is to have this file in the Java source path
as Eclipse copies all resources automatically into the build dir when compiling.

Hope this helps
