IO Web Helpdesk - Java


Where is Java?

Java is installed on both webservers (www-01.io.com and langley.io.com) as well as on the Linux userhost (atlantis) as


/usr/bin/java
More importantly, the Java Development Kit is installed on all three of these hosts in

/usr/bin/jdk-1.1.1/

What's in the JDK?

Probably more than you will be willing to learn unless you are a full-time Java programmer. A quick look at the files gives us the following (installed in /usr/bin/jdk-1.1.1/i586/green_threads/):

drwxr-xr-x 2 root root 1024 Jul 1 15:27 ./
drwxr-xr-x 3 root root 1024 Jul 1 15:27 ../
-rwxr-xr-x 1 root root 1420811 May 20 09:42 java*

-rwxr-xr-x 1 root root 123 May 20 09:07 jdb*
There are many symbolic links made to all of these files that should make everything work just fine for you.

Where can I learn more about Java?
