Applet using imported library doesn't work
Nov 18th, 2008, 2:10pm  
hi there
i'm importing the pdf library to write a pdf and it works fine when i run the program from the IDE but when i export an applet it doesn't work at all.  if i run from the webpage i get an X at the top left corner of the applet window and the java console gives me the following:

Code:

java.lang.UnsupportedClassVersionError: stereotomic (Unsupported major.minor version 49.0)

likewise it tells me it can't find main class if i try to run it as an application.  in the end, though, i just want to be able to run it from a webpage. any ideas?

Code created by Processing requires Java 1.5 or later. You'll get this error if you have Java 1.4 or earlier installed as your default.
