Ubuntu 12.10, 32bit
Problem too damn simple: I have a NTFS partition and unpacked from .tar.gz jdk on it. All I need from bash, is to see javac compiler, that is located in directory /media/mallniya/data/jdk1.7.0_25/bin. As it advised, I add the path to the javac in $PATH like this:

export PATH=$PATH:/media/mallniya/data/jdk1.7.0_25/bin

output of $echo $PATH:
And then I try to found or execute javac AND HAVE NOTHING:
output of which javac gives just nothing;
output of ls -l in the /media/$USERNAME/home/mallniya/jdk1.7.0_25/bin (without other files):

-rwxrwxrwx 1 root root 5897 Jun  6 06:13 javac

output of javac ( do exist, permission is ok):

bash: /media/mallniya/data/jdk1.7.0_25/bin/javac: Permission denied

output of sudo javac

sudo: javac: command not found

If the same directory jdk1.7.0_25/bin located on the other partition (ext4, for example), the problem is disappear.

I've found no restrictions about adding path in environment variable $PATH, but, obviously, for whatever reason it doesn't work with paths of NTFS partition.

Question: is it possible to add NTFS paths in the $PATH? I understand, that I can use the other path to add in the $PATH, but for now I want jdk to stay where it is. Thank you.

Welcome to Ask Ubuntu! Please provide the output of cat /proc/mounts. This will list the mounts and mount options. I suspect noexec is added as an option to your drive at /media, which will not allow to run applications from that medium. I can provide an answer if that's the case. Provide the information by editing your question. – gertvdijk Jun 23 '13 at 12:02
Do you really need to install the JDK from upstream tar file? The Oracle Java JDK is available in a PPA: – gertvdijk Jun 23 '13 at 12:05
On a side note, use type rather than which to see what/where the command is. type javac, or type -a javac to also see other javac commands available. – geirha Jun 23 '13 at 13:53
@gertvdijk, thank you for rapid response and I'm so sorry about my slow reaction :( The output of cat /proc/mounts now in the question. And yeah - it's better to use PPA. @geriha: your method actually works and javac dispays in the output of type javac. – mallniya Jul 1 '13 at 1:15
And a little surprise for me: it's eventually worked, when I had changed /etc/fstab like this:<br> UUID=7A0063220062E49B /media/mallniya/data ntfs 0 0 remount and try which again. All is ok. And the other important thing: to the output of cat /proc/mounts in the line /dev/sda3 /media/mallniya/data was added only string default_permissions. I'm pretty sure, that's the problem was with mount options. – mallniya Jul 1 '13 at 1:51
