Question

So I have a program that runs something like the following

public class SHandler extends Handler { 
    File lmpFile;

Down later in the program:

lmpFile = new File("Stuff.zip"); // This should create a file called "stuff.zip" in the present directory
OutputStream fos = new FileOutputStream(lmpFile); // Fill the file with whatever

Then from my main I call

 S.SHandler SpecialSH = new S.SHandler(args);
 //use the object for whatever
 SpecialSH.delFile();

Delfile is made like this and is a method inside the class:

public void delFile() {
    lmpFile.deleteOnExit();
    lmpXMLFile.deleteOnExit();
}

To my knowledge this program works right on my local machine (Windows 7 Enterprise), however on our development box when I run this it’s tossing a LOT of files that the program pulls all over the place. The execution path is /usr/data/dev/Handler and it’s putting “stuff.zip” (and the files extracted from it) in /etc/cron.d and despite trying to remove them I am unable to.

Note This program is being called via a bash script which is invoked by a cron job on a machine running RHEL6. Anyone able to help this would get my undying love and appreciation.

Edit: The bash script is simply:

export JAVA_HOME=/usr/data/java/current
export PATH=$JAVA_HOME/bin:$PATH

/usr/data/java/current/bin/java -jar /usr/data/dev/Handler/Handler.jar

Tl;DR: File runs fine on windows, when RHEL6 calls a cron, files end up where they shouldn’t. How can I make my program handle this?

Answer 1

It looks like the working directory is /etc/cron.d/ (executable path is different).

Relative paths (when using java.io.File), are relative to the working directory. If you want your files placed in a different directory, use absolute file paths: /path/to/stuff.zip (note the leading slash).
