850 'missing objectspace' errors

I'm trying to use Visual Age 4.0 to put togather a bunch of servlets.  There is this jar file called jgl3.1.0.jar which when i import into the project, errors go from 5 to 855.
The messages are mostly
'Field type com.objectspace.voyager.util.Tokes is missing'
'Superclass com.objectspace.voyager.VObject missing.'
What do i need to to get the objectspace stuff clean compile.
the code is

import java.io.*;
import java.util.*;
import com.ibm.eNetwork.ECL.*;
import com.objectspace.jgl.*;

 * * At init time the max number of 3270 connections are established * along with timeout limits for age and idleness. *
 * Every five minutes the connections are validated.  As connections * exceed the maximum idle time they are removed from the connection
 * pool.  As connections exceed the maximum age they are disconnected * and restarted.
