# How to install and use arara package?

I am interested in using "arara" package. According to it's manual my below code should run without any error:

% arara: pdflatex
\documentclass{article}

\begin{document}
Hello world.
\end{document}


but I get nothing and have problem with this code. It should be mentioned that I install Java after installing LaTeX. Error:

Process started: "C:/texlive/2015/bin/win32/arara.exe"

• but can java be found on the commandline? Try running java in a dos prompt – daleif Jul 28 '16 at 10:45
• You don't need the JDK just to run arara. The JRE should be sufficient. (JDK is for compiling the Java code. The JRE is just for running pre-compiled Java code.) What do you get if you do java -version in the dos prompt? – Nicola Talbot Jul 28 '16 at 14:26
