Depending on the shell you have on the remote server, different profiles 
  can be loaded therefore you can have different PATH env. I use bash, 
and ssh loads the remote .bashrc, but not .bash_profile therefore my 
$PATH in .bash_profile is not loaded when I use ssh remoteserver command.

For example, my command "a" just has "echo $PATH". It shows different 
output under different env.

// my current PATH
[vu at ef ~]$ . a
/home/vu/jdk1.6.0_07/bin:/usr/lib/qt-3.3/bin:/usr/kerberos/bin:/usr/lib/ccache:/usr/local/bin:/usr/bin:/bin:/home/vu/bin

// my PATH when I execute the command a via ssh
[vu at ef ~]$ ssh vu at localhost . a
vu at localhost's password:
/usr/local/bin:/bin:/usr/bin

You can see the path to my local JDK is missing in the latter case. If I 
had the java command in "a", I would also get "command not found" when 
remotely running a via ssh, if I do not have java in other listed paths.


hth,
