# Where can i add an native path (to the .dll) in KNIME to an added .jar-File?

Hello,

well i have a .jar file which needs an native path to the a related path with a .dll-File?

Thanks a lot,
Johannes

Hi Johannes,
the dll needs to be in the root folder of the plugin and needs to be exported during build. For more details see http://dev.eclipse.org/newslists/news.eclipse.platform/msg50613.html.
Another nice article describing the Eclipse VM its classloader system and nativ code handling can be found here http://www.eclipsezone.com/articles/eclipse-vms/.
Bye,
Tobias
