com.sap.mw.jco

hello,

i am trying to connect my system to Sap system through java class...

in my class i used the following statements...

import com.sap.mw.jco.*;

public class Connect1 extends Object {

JCO.Client mConnection;

it is giving errors as

"the import com.sap.cannot be resolved"

"JCO cannot be resolved to a type"

does the java lib comes with com.sap.mw.jco or we have install these ones separately...

thank you,

aj.
