I have created an account on World of Minecraft, and downloaded the client and minecraft.jar file, and placed it in the lib folder. Whenever I start the server client, it lets me log in, place a "play.jsp" URL, and click "Go!".
It says the regular stuff like "soiling" and stuff. When it gets to planting, the client crashes and the command line says:

I have no clue what to do from here on. Any help would be appreciated. Thank you.
