Problem running VisAD

["Adrian Wyss" <adrian.wyss@xxxxxxxxxxxxxxxxxx>]

Hello

I have problem runing VisAD.
If I try to run the first example (P1_01.java)of the VisAD Tutorial I
reveive the following exception:

java.lang.NullPointerException
        at visad.DataImpl.computeRanges(DataImpl.java:1271)
        at visad.DataRenderer.computeRanges(DataRenderer.java:388)
        at visad.DataRenderer.prepareAction(DataRenderer.java:346)
        at visad.DisplayRenderer.prepareAction(DisplayRenderer.java:842)
        at visad.DisplayImpl.doAction(DisplayImpl.java:1644)
        at visad.java2d.DisplayImplJ2D.doAction(DisplayImplJ2D.java:312)
        at visad.ActionImpl.run(ActionImpl.java:353)
        at visad.util.ThreadPool$ThreadMinnow.run(ThreadPool.java:95)

The classpath is set and the VisAD SpreedSheet (java
visad.ss.SpreadSheet) runs fine.

Thank you in advance...
