Astrostack

[Norman Silverstone]

I am trying to run a piece of software called Astrostack. To do that I
entered java -Xms256m -jar AstroStack3le.jar and got the following
message:-

Exception in thread "main" java.lang.NoClassDefFoundError:
com/innostack/astrostack/AS
   at gnu.java.lang.MainThread.run(libgcj.so.7)
Caused by: java.lang.ClassNotFoundException: com/innostack/astrostack/AS
   at java.lang.Class.forName(libgcj.so.7)
   at gnu.java.lang.MainThread.run(libgcj.so.7)
norman at gruber:~/Desktop/AstroStack3LE $

What do I need to do to make things work please?

Thanks in advance

Norman
