Unable to run terminal commands from Java for latex

Question

Latex file: 0.tex content:

\documentclass{article}  
\begin{document}
\begin{equation}
\frac{\partial p_{dyn}}{\partial n} = A
\end{equation}  
\end{document}

Shell file: 0.sh content:

latex /u/b/basnet/Desktop/0.tex
dvipng /u/b/basnet/Desktop/0.dvi

Command in Terminal:

>chmod 755 /u/b/basnet/Desktop/0.sh
>/u/b/basnet/Desktop/0.sh

Output: Image, Dvi and other files generated by latex. You can see in the blue window.

Problem: This works only via terminal not by executing the command via Java program.

Java Program Code:

Runtime.getRuntime().exec("chmod 755 /u/b/basnet/Desktop/0.sh");
Runtime.getRuntime().exec("/u/b/basnet/Desktop/0.sh");
System.out.println("Script executed successfully");

Output:

run:
Script executed successfully
BUILD SUCCESSFUL (total time: 0 seconds)

The first line of the code i.e. making the file executable works fine as I cross-checked. But second line where the script file contains the latex command doesn't work when running via Java. I need to generate those files through my program.

Answer 1

我想这需要对环境做些什么，我对所有这些操作系统的东西都不太深入，但我认为我的解决方案适用于我的电脑上的示例：

您必须将程序名称更改为在shell文件中使用的完整路径，因为Java运行时无法找到它们。例如：

/Library/TeX/texbin/latex /u/basnet/Desktop/0.tex

唯一出错的是，输出文件出现在tex文件所在位置的一个文件夹中，这意味着您必须更改输出目标或执行dvi的行。

如果您找不到程序的路径，请打开bash并输入

which latex

和

which diving
