Anyway, I managed to fix it thru included the "import > java.io.IOException;" and "throws IOException" in the program. Oops, sorry! I've changed my examples to add IOException where needed. The reason it was missing is that, while writing my example application, I made a slight improvement to visad.data.DefaultFamily, the class which takes a String or URL argument and returns the appropriate VisAD Data object. Previously, the DefaultFamily open(String) method only tried to open a local file; to open a web-based file, you needed to call the open(URL) method. Now the open(String) method tries to open a local file and, if that fails, will try to build a URL from the String and open the URL. While making these changes, I managed to get rid of the IOException the open(String) method used to throw. (The latest version of VisAD on the FTP/web site has these changes.) > The program > runs but a runtime error bug is displayed.

It's already been reported to Sun so you can just ignore it until they get it fixed.
