Hi Travis, This is a general question that applies to any Java program that you want to run, so you may want to Google around. Briefly, Java looks at an environment variable <https://secure-web.cisco.com/1GCUQrhkhRHdvgReJlUefe17Zsa7ONL9S2XXix5Fnz07i1QQLqge_yp9bPTv5fkAYeI_elr4SKwePsGnPjoRNOqWg_0YxfVMBA6aF4QOIZDd9Ulg2QA1nsejDH6RTOXGQq7Uj3LDihMus2dhiu2Ge8YaL92s4x3Kcha0GLWPoGC8WMiw3XF1RGlaBlaMbcPJQjTR9BAG87ZcfDmrfmK3qYuSB9M-xNLc3iH1g9Mzr4X2h1ooR8xrpce2W-pP2kU-sdHYxZDyD0HWZqHZeKZsddy29cor6vsJN6G34y70RmtjrUMYlY7Ranm0gUmSXVomT2lvbEggZQ62j-DOnqVOOJ9mOVB1cBtwZzNsnNqVIXdhrPyC2kOt_GAbMoDhL4cHdi8LGABE-MpNJgl-badPtDRlAUK44VLovlddICILO1VY54ET_UKG3i_oFePrR5n6CcS9auyqOCcIEePASt2s42Q/https%3A%2F%2Fdocs.oracle.com%2Fjavase%2Ftutorial%2Fessential%2Fenvironment%2Fpaths.html> to look for libraries and Java classes that you have installed. When the tutorial asks you to run a command like 'java ec.Evolve -file tutorial4.params', it's assuming that you've already added the ECJ jar (and the jars for its dependencies) to your CLASSPATH.
