wow..
sometimes solutions can be very simple.
And.. tata.. loading of MrSID layers works with your origial code (and
in Eclise.)
thank you Larry!
Next weekend I may tackle the then the following things:
a) I get an error message, when I use Zoom WMS Layer (which should of
course not work, as it isn't a WMS layer)
(com.vividsolutions.jump.workbench.model.WMSLayer.getService(WMSLayer.java:240))
Do you have here any hint too?
b) to adjust the folder settings for OpenJUMP (i.e. use
context.getWorkbench().getPlugInManager().getPlugInDirectory())
c) think about the automatic creation of a tmp folder
d) check why MrSID does not run with Paul's Framework

Don't miss this year's exciting event. There's still time to save $100.
Use priority code J8TL2D2.
