Dear Dave, I try to compile and run the sample application that you put up in the collaborative pages. However, I faced some problem when compile and running it. Anyway, I managed to fix it thru included the "import java.io.IOException;" and "throws IOException" in the program. The program runs but a runtime error bug is displayed. May I know what is the error means? D:\PROJECT>java DisplayGIF A nonfatal internal JIT (3.10.107(x)) error 'regvar' has occurred in : 'visad/data/DefaultFamily$FormFunction.run ()Z': Interpreting method. Please report this error in detail to http://java.sun.com/cgi-bin/bugreport.cgi Thank you. -----Original Message----- From: Dave Glowacki Sent: 7/12/00 5:56 AM Subject: Corrected URLS for collaboration tutorial > I've written a set of tutorials on how to convert VisAD > standalone applications to collaborative applications.
