Dear Bill Hibbart, With reference to the e-mail dated 24 June 1999, I downloaded the latest version of Visad package and compiled it successfully. But I encountered a problem in executing the SpreadSheet Application. Problem encountered: I'm working on Windows98 environment in my home computer. I tried to execute the application using 'java -mx64m visad.ss.SpreadSheet' but it gave the message, "cannot construct spreadsheet cells. A remote error occurred: Listen failed on port:0; nested exception is: java.net.SocketException: Option unsupported by protocol: create" My home computer is not connected to a network. But in my computer in the University which is working on WindowsNT environment I was able to execute the SpreadSheet application without any error and it is connected to the network. But in the Display menu 'Java3D' is disabled, although I have installed Java3D, and the icons are not visible in the button bar. Please be kind enough to support me in this situation. Thanking you, Yours sincerely, S.D Senaratne N.B I have sent this email previously. But I didn't get the support.
