Use of JCo

Question

Hello Everyone,
                       I m developing one portal application using NWDS. This application connects to backend SAP R/3 system & fetches the data in some table. i have decided to use JCo to connect to R/3 system. But in my code it gives me error at the import statement "import com.sap.mw.jco.JCO;". so my question is , Are there any configurations or any .JAR files need to be added for using JCo while developing portal application through NWDS?
Thanks,
Chetan
