Erkanaksoy,

In you rEclipse project you need to add the external JARs in the NMSDK/lib/external folder to the project. You will then find that the class will compile and run from Eclipse.

Hope this helps if you haven't solved the problem already.

Regards

Martin

Ratna,

You need to have the following libraries in your class path

common/nmsdk-runtime-5.4P1.jar

external/commons-codec-1.4.jar

external/commons-io-2.0.1.jar

external/commons-lang-2.6.jar

external/guava-r08.jar

and then your DFM or ONTAP API jar for the version you are tring to communicate with. These can all be found in the lib folder for the SDK

Hope this helps

Martin
