If PickTest.class is in your current directory and :
java PickTest
gives you the error, then your CLASSPATH is not set to search the current directory.
On both Windows and Linux you have to set the CLASSPATH to execute programs from the current / working directory to be targeted as something to load and run.
On my Windows partition I have this command in the autoexec.bat on win-9x:
CLASSPATH=.;C:\Java\sdkSymantec\BIN\COMPONENTS\SYMBEANS.JAR;C:\Java\sdkSymantec\BIN\COMPONENTS\DATABIND.JAR;C:\Java\sdkSymantec\JAVA\LIB\CLASSES.ZIP;C:\Java\sdkSymantec\JAVA\LIB;C:\Java\sdkSymantec\BIN\COMPONENTS\DBAW_AWT.JAR;C:\Java\sdkSymantec\BIN\COMPONENTS\SFC.JAR;C:\Java\sdkSymantec\JAVA\LIB\DBAW.ZIP;C:\Java\sdkSymantec\JFC\Swingall.jar;%CLASSPATH%;%QTJava%;
SET CLASSPATH=C:\JAVA\VMBIN\JMF20\LIB\SOUND.JAR;C:\JAVA\VMBIN\JMF20\LIB\JMF.JAR;%JMFSERVER%;%QTJAVA%;.;%CLASSPATH%
that has links for using Sun's Java Media Framework ( JMF ) this might be enough for simpler situations:
SET CLASSPATH=.;%CLASSPATH%
"." means the current ( or local ) directory.
From DOS I think you can type
ECHO $CLASSPATH or ECHO CLASSPATH
and it will tell you the current setting of your CLASSPATH
For windows you would have to reboot to have it take effect.
I'm using Linux ( Redhat 7.2 ) now, and the settings of the path is different but I think that's what you need for windows.
People are still using Windows ?
The Unixes ( including Linux ) are by and for developers, and Java3d runs there too. ;^)

Another Picking Example shows the SceneGraph and loads a VRML file ( source code available ):

A screen capture of this was recently posted to this list showing Selman's Picking from a Vrml Scene by some kind sole just a week ago ( Saturday April 5, 2002 ) because lots of people seem to be interested in Picking objects and Loading VRML scenes which the Sun VRML Loaders do well as you can see:

Yes Fausto, see the above links !

Newbies like you Fausto and hterrolle keep asking the same questions ( eg. Picking, as you both did ) and as I have had it working I showed both to answer the current questions, and to preemptively answer future concerns, and have it in the archives for future referance.
People on the Java3d list don't necessarily know about VRML.
The Spaming complaint seams so "Couch-Beitler Flame War", the Picking with Java3d using VRML is not off-topic for Java3d and has been in responce to either questions or new events.
One reason I've posted more screen shots recently was because of the recent lies from Yumtech.com by Justin Couch in his unethical and illegal false and fraudulent claims in continuation of the "Couch-Beitler Flame War".
The fraudsters at Yumtech.com have suggested falsely and fraudulently and without cause or reason that I have "faked" screen shots on my web site and the lies and criminal conduct of the fraudsters at Yumtech.com, Prentice-Hall, and the NIST hurt our community and country, you, me, and the other people on this list.
One reason I've posted the images to this list is to document and defend the truth which includes the fact that the Sun VRML Loaders can and do animate Web3d.org's VRML based H-Anim Avatars despite the lies, fraud, and criminal conduct of Justin Couch, Aaron Walsh, Sandy Ressler of the NIST and Prentice-Hall Publishing.
