Ah yes - I forgot "call".

Using 1.38x and the following method of my FitsJ class

                public static String getCardValueFromFile (String key, String  
image)

in a package located in the jar

                plugins/astroj.jar

and invoking call via the macro

                title = getTitle();
                exptime = call("FitsJ.getCardValueFromFile","EXPTIME",title);

I get an error message sayting that ImageJ can't find the FitsJ class,  
a problem normal plugins don't have.   Even tried renaming the jar to  
astroj_.jar......
