Running an exe from Java

[whodaman]

I'm trying to make a local java appication that would like to run an exe file with a parameter (say a text file). I've looked into several books and it said nothing about it. Thank you in advance.

In the JDK look at java.lang.Runtime.exec()

Also search in

http://www.javaworld.com

for an article on how to use Runtime.exec() correctly. There are a few issues that you need to be concerned with.

Also, does it have to be your own Java program. I recommend you take a look at Ant project at jakarta.apache.org. The use of Ant is quite easy. There is a supported task called 'exec'. It may be easier for you to create a build.xml file then to interface with Ant from your Java program????

Hi whodaman,
It is possible to invoke an application with parameters.
For eg.,
Runtime r = Runtime.getRuntime();
r.exec("notepad"
would open an untitled notepad, while,
r.exec("notepad c:\\logfile.txt"
would open up the logfile.txt file.
So the same, should be applicable to other applications too.
Hope this helps.
