Are you running through Web Start? If so, we have just recently encountered this problem also and are looking into a solution. For some reason, on SPARC systems, Java 3D is not being downloaded or accessible from a place that Web Start can find. Also, please note that the IDV will not work with Java version 1.5. A quick work around would be to install Java 1.4.2 and Java 3D locally on your machine and point Web Start at that. Or, use the InstallAnywhere installer for the IDV which has both of these bundled with it.
