[ros-users] rosjava external jars

[Jeremy Wright]

Nicholas,

Thanks for the reply. This doesn't seem to be working for me, perhaps you
can tell me what I'm doing wrong.

I'm trying to get this working with the rosjava tutorials you sent to us
here at the UofA. I created an externalLibs package like the one you
described, with a jar directory. It contains one jar
(jfreechart-1.0.13.jar). I added your cmake code below to CMakeLists.txt and
I added one line to Talker.java:

import org.jfree.*;

However make still gives the error:

Talker.java:3: package org.jfree does not exist
import org.jfree.*;
^
1 error

It seems like it's not finding the jar?

Thank you for your help,

Jeremy
