Noobie: Wierd error when doing tutorial 2

Hey guys, im VERY new to Screen Scraper, i've been learning how to use this program remotely through a server. When i try to run scraping sessions (this happened when i tried running the scraping session on tutorial one as well) I get a java error and after the first tutorial, i tried looking at the compiled text file and there was nothing in it (Java error as well) ill post the error from the log and hopefully you guys can help me with this problem so i can see some results :)
