I'm trying to use the GeodeticCalculator to calculate an orthodromic
distance, but I've this error when I try to compile my code :
java.lang.NoClassDefFoundError:
org/opengis/referencing/crs/CoordinateReferenceSystem
at Distance.init(Distance.java:18)
at sun.applet.AppletPanel.run(AppletPanel.java:378)
at java.lang.Thread.run(Thread.java:595)
Generally speaking, when the throwable class name end with "Error"
instead of "Exception" (as in "NoClassDefFoundError"), it is almost
always an installation problem. The most common causes are: 1) a JAR
file missing on the classpath, or 2) mixing JAR files from different
Geotools versions.
I use Eclipse3.1.1 on Linux... I've compiled Geotools 2.2.x branches
with maven 1.0.2 (build successful). It may be a problem with eclipse
but I don't really know ...
I can't help with Eclipse, and the sample code provided is quite simple.
The GeodeticCalculator has no sophesticated dependencies. Just make sure
that geoapi-2.0.jar and vecmath.jar are in yours classpath.
Martin.
