Ok.

I have no idea right now and no time to digg into it.

Aug 30, 2010 9:52:27 AM org.geotools.coverage.io.netcdf.NetCDFDriver <clinit>
SEVERE: it/geosolutions/imageio/ndplugin/BaseImageReaderSpi
java.lang.NoClassDefFoundError:
it/geosolutions/imageio/ndplugin/BaseImageReaderSpi
	at java.lang.ClassLoader.defineClass1(Native Method)
	at java.lang.ClassLoader.defineClass(ClassLoader.java:621)
	at org.eclipse.osgi.internal.baseadaptor.DefaultClassLoader.defineClass(DefaultClassLoader.java:188)

suggests me that the imageioext-geocore should be of the trunk
versione, but even if I try with that, it doesn't work.
It is a while I do not follow those jar-mixes any more. This is
frustrating every time.
