Question

I am using windows 7 and program in Netbeans platform. I have wrote this line:

Runtime.getRuntime().exec("cmd /c start make.bat");

When I run the bat it works perfectly, but then java calls it this is what I get:

C:\Users\RB\Documents\NetBeansProjects\BinaryTree>dot -T png -o tree.png tree.dot

'dot' is not recognized as an internal or external command,
operable program or batch file.

C:\Users\RB\Documents\NetBeansProjects\BinaryTree>cmd
Microsoft Windows [Version 6.1.7601]

The contents of the bath file is:

dot -T png -o tree.png tree.dot

Answer 1

Try to specify full path to ‘dot’ program in your bat file. It is possible thet environment variables like PATH are not the same in Runtime.getRuntime().exec() and your OS.
