Here are instructions for making the javac and java commands access the latest version of the Java compiler (until such time as the osprey system administrator makes the change on the system). Edit your .profile file. It is in your home directory. Note: you don't normally see files whose names start w/ a '.' when using the "ls" command. To see all files, even those beginning w/ a '.', use the -a option for "ls", e.g. "ls -a" or "ls -al" If you are in your home directory you can type: "pico .profile" or "vi .profile" If you are in another directroy, you can type: "pico ~/.profile" or "vi ~/.profile" (The "~/" says "go to home directory for the file .profile") Add a line to this file: export PATH=/usr/java/jdk1.5.0/bin:$PATH Then you must execute the new .profile file either by logging out and back in or by the command (from your home directory): ". .profile" Note: you will likely need to remove this line once the system changes have been made. As soon as I hear anything about this, I will let you know. javac and java commands
