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.

I don't think you want to import the jar into your project. All you need to do is include it in your classpath.

Have you added the jar to your projects classpath?

I've imported the .jar file into the project.  I'm assuming Visual Age is including it in the classpath.

If it can't find com.objectspace.jgl then it sounds like the jar is not in your classpath.

I'm wondering if
Field type com.objectspace.voyager.util.Tokens '
and         'Superclass com.objectspace.voyager.VObject'
is included in the jgl3.1.0.jar.
I see there is something called voyager at the objectspace website so i'm going to download it now to see if  voyager.VObject in there.

There certainly is a product called Voyager (very nice 2).
Though I doubt that jgl would have any dependencies on it.

You can open a jar with any zip tool if you want to have a look at the contents.

OH!! you mean you don't think i want to import the jar files into the project. Yeah that's a big inprovement when i put them into java12/jre/lib/ext directory.
thanks.  I'll probably edit that other question to something completely different.

JGL has some Voyager dependendant classes. If your not using Voyager and you don't use these classes then you shouldn't have a problem.
My importing the jar into VAJ it appears to be going through the entire jar and complaining about the Voyager dependant stuff (which u aren't using).

Another solution would be to remove the voyager dependant classes from the jar.

Whoops, forgot to accept comment for answer.  I'll have to figure out your last
comment. If I put all the jar files in the ext directory i get 76 errors, down from 1072.  If i
 then import the jar files except for the jgl jar it goes down to 5 errors.  The message is 'Import specifies a type that is not visable com.ibm.eNetwork ECLECLErr'.   Maybe when i figure out your last comment
that 'l be it .  
thanks
