[tcljava-user] Using Tcl Blend with NASA WorldWind Java SDK

[<Dan...@dl...>]

Hi,
=20
I'm trying to use Tcl Blend together with the NASA WorldWind Java (WWJ) =
SDK, i.e. creating WWJ objects from Tcl, accessing their fields, =
invoking their methods, etc. [WWJ uses JOGL for the visualization of a =
virtual globe (analogous to Google Earth)]

I have been able to create JOGL objects from Tcl, such as GLCanvas, =
GLJPanel, and some WWJ objects such as IconLayer, =
EarthNASAPlaceNameLayer, etc. but I have not been able to create some =
WWJ objects, in particular WorldWindowGLCanvas and WorldWindowGLJPanel.

Specifically, I get the following error message when trying to create a =
WorldWindowGLCanvas object from jtclsh:

 medina@onyx:/opt/tclblend/bin> ./jtclsh
 % package require java
 1.4.0

 % java::new gov.nasa.worldwind.awt.AWTInputHandler
 java0x5
 % java::new gov.nasa.worldwind.awt.WorldWindowGLCanvas
 java.lang.ExceptionInInitializerError

 I would appreciate it if anyone could provide some help on this.

 Thanks in advance!
