试图在Java中复制PHP exec（）函数

Question

I'm trying to replicate PHP's exec function in a Java application. Here's the PHP code:

exec('C:/executer.au3');

And here is the Java code:

Runtime.getRuntime().exec("C:/executer.au3");

When I run that I am getting an IOException saying:

Exception in thread "main" java.io.IOException: Cannot run program "C:/executer.au3": CreateProcess error=193, %1 is not a valid Win32 application
    at java.lang.ProcessBuilder.start(ProcessBuilder.java:1029)

    ... 5 more

I'm a bit out of my element, how can I get this au3 file to open in Java?

Answer 1

The file you mention is an autoscript file that does not do anything by itself. Like a text file.

You probably need to supply the program that will run the file - the Autoit.exe program for example.

Runtime.getRuntime().exec("/Path/To/Autoit.exe C:/executer.au3");

Along those lines - I cannot test at the moment.

The PHP exec version may somehow trigger the default program for .au3 files. That's just a guess.
