JavaMapScript

Hi all,

I'm trying to use the JavaMapScript package and have run into some difficulty. 
When I run the DrawMap test file included with the distribution I get two 
different errors.

This first error I get when I reference a map file that is not in the same 
directory as the java class file:

C:\eclipse\workspace\tekmaps\.deployables\tekmaps\WEB-INF\classes>java 
-Djava.library.path=c:/mapscript -cp 
.;c:/tekmaps/mapscript/debug/java/mapscript.jar DrawMap example1-8.map map.jpg
Exception in thread "main" java.lang.UnknownError: No such file or directory
         at edu.umn.gis.mapscript.mapscriptJNI.new_mapObj(Native Method)
         at edu.umn.gis.mapscript.mapObj.<init>(mapObj.java:328)
         at DrawMap.main(DrawMap.java:34)

The second is slightly different, but I suspect it's related to the first:

If I put the map file, in this case example1-8.map in the classpath, I sometimes 
get a java IOException:

C:\eclipse\workspace\tekmaps\.deployables\tekmaps\WEB-INF\classes>java 
-Djava.library.path=c:/mapscript -cp 
.;c:/tekmaps/mapscript/debug/java/mapscript.jar DrawMap example1-8.map map.jpg
(example1-8.map)java.io.IOException: (example1-8.map)
         at edu.umn.gis.mapscript.mapscriptJNI.new_mapObj(Native Method)
         at edu.umn.gis.mapscript.mapObj.<init>(mapObj.java:328)
         at DrawMap.main(DrawMap.java:34)

I can't find any documentation on these errors at all. What little documentation 
I have been able to find is a couple of years old. Is there anyone out there now 
using Java MapScript who can steer me in the right direction with this?

Thanks,

Roger Bixby
