Execute an exe using java code

[shoby]

Hi,

I need to execute an exe from a java application.The exe follows a partticular format when it is executed from command line. The format is as below:

( exe-name < input.txt ) > output.txt

where exe-name is the name of the exe, input.txt is a text file that contains the input to the exe, output.txt is a text file that will contain the output once the exe has executed.

I tried using the Runtime.getRuntime().exec();
But it does not seem to work.

Does anyone have a suggestion on any alternatives?

What exactly didn't work? Things can go wrong with Runtime.getRuntime().exec(), but that doesn't mean you should be looking for an alternative. Please post relevant code and we'll help you fix it.
