I'm having difficulties finding the JVM on my Mac 10.6.8. I have downloaded and installed the most recent JAVA additions. What files I found said I had to change the export path in a file labeled bashrc or in a JVM file. I tried searching through all the hidden files to find a "bashrc" file, and the "JVM" or "J virtual machine" itself without any luck. I do not have trouble finding the compiler which I found using the "which" command. Who knew they were not located in the same spot...The only thing I can think of is that it's under a different name than what is in the book, possibly.
