Hi, You probably have multiple Java installations. The active JRE might be a different one (e.g. the one installed by Windows), so you would have to find out which JRE is the active one and where it looks for the libraries.
Have you tried the Java program that was attached to the mail I referred to? You can find this program in this link: https://www.millennium.berkeley.edu/pipermail/tinyos-help/attachments/20090112/632b46f9/attachment.txt Save the contents into a file called LibTest.java, compile and run it. It will show you a list of directories where your active JRE will look for the libraries. Put the two libraries into one of the directories listed there.
