[Tex/LaTex] What are the latex and dvips path in jaxodraw preferences

feynmantexlivetexmaker

I am using "jaxodraw-2.1-0.jar" and the "axodraw4j.sty" file is inside the directory where I am drawing and keeping my diagrams. Whenever I try to export the diagram it shows "Cannot execute command! Please try 'export LaTeX' and run latex manually." so I did. I ran the generated latex code using my "texmaker". First I used "pdflatex" and it generated a blank figure with just the latex labels but no arrows or anything ! Then I read somewhere that I must do "Latex->Dvips->Ps2Pdf-" etc so I configured my "quickbuild" tab in texmaker that way and executed which showed the following error

Process started

So I came back to jaxodraw and opened "preferences", I saw that the two fields: latex path and dvips path are empty. I wrote latex in the latex path and dvips in the dvips path because I don't know what else to do.. I have no idea what is the exact path for them ! Then I tried to export again using the default "LaTeX->EPS" it showed another error: "Error:_Executionof_dvips_failed!" I think if I could specify the right paths for latex and dvips it will export correctly and will directly generate the EPS file.. because I remember I used jaxodraw in another computer with ubuntu many months ago and that was generating the EPS directly and seamlessly ! But I don't know what are the paths.

Additional info:

I am using Ubuntu 16.04.1 LTS and it's Lubuntu.
I have installed Texlive Vanilla following the instructions given here: How to install "vanilla" TeXLive on Debian or Ubuntu?

Any help will be highly appreciated because I am really stuck.

PS: If I choose just "EPS" instead of "LaTeX->EPS" it produces the diagrams without any latex labels, so again useless.

The error message indicates that your TeXLive installation is corrupted or incomplete. It shows that the programs latex and dvips were indeed run, but that the files texmf.cnf and tex.pro are missing, even though they are essential to the functioning of these programs. They should have been created by a standard install of TeXLive 2015 in the following locations:

/usr/local/texlive/2015/texmf.cnf
/usr/local/texlive/2015/texmf/web2c/texmf.cnf
/usr/local/texlive/2015/texmf/dvips/base/tex.pro

I would recommend reinstalling TeXLive (of which the current version when I wrote this answer is TeXLive 2016). I'd recommend you to make this a full installation, and take the default options.

After that latex and dvips should work.

Once you have a correctly functioning TeXLive installation, jaxodraw's export to eps should work with jaxodraw's default settings for the paths to latex and dvips, which are just the strings 'latex' and 'dvips'.
