I've always noticed that the classloader loads things in alphabetical order. Additionally, if it finds the same class in 2 different jars, it only seems to use the class from the first jar. I would suggest just trying to rename the "important" jars if possible with a prefix of something like aaa_<jarname>.jar to force the classloader to pick it up first. Just a thought....
