The method you suggest was known to me, but the thing is i do not want to execute anything apart from using fstab file. If everything else fails, I will use this method as the last resort.
There are two phases to getting what you want:
1. Preparing the filesystem, and 2. Setting up the fstab file.
If the filesystem is prepared properly, the following fstab file entry will work:
/dev/hdh3 /tmp ext3 defaults 1 2
Now, could you run those commands and show us the output?
