Install CDK Extension in eclipse-KNIME runtime


Situation: I have *.table file which needs the CDK-Extension to be read correctly.
My Problem: I want to test my self-written Node with this data, but the KNIME-runtime started from eclipse (when I run my project) doesn't have extensions installed.

Menu --> Install Extensions  shows no entries to install.

Thank you very much.


PS: I'm working with the latest SDK (eclipse 3.6.1 , Knime 2.3.1) 64bit, Win
