Thanks, Steve, for your explanation. I think I understand your point and
examples. Still, I would like to understand what the problem is with
trying to use file.separator and path.separator. Are you saying they are
just broken or unreliable in their implementation?

I am having problems getting the file and path separators working right,
so I'm looking for an example pgm for use in writing a file to a
specified, arbitrary place.

For example, suppose I have the following folder hierarchy on machine


and I want to create a File "outputfile.txt" that will be written into
folder "ChildFolder".

Can anyone provide an example that works? My system properties are set to

  path.separator =:



I've tried far too many permutations and combinations of ":" and a "/"
without success. What am I not getting about separators?


Bill Christens-Barry

it's a Pig.(it's java)
the best way to do it is to use :
URL jarUrl = new URL( "file:/path/to/my/app/updatable.jar" ); (this works
on osx/windows/linux)

if you use URL , then it is the SAME for all platforms , forget about setting
or screwing about with
file.separator etc.

actual working code examples:

  ourProgramDirectory = System.getProperty("user.dir");
int loop=0;
while (st.hasMoreTokens()) {
                final URL x1 =new URL(((("file:" + ourProgramDirectory) +"/")
+st.nextToken())); //this is a URL so do not use fileSep
                OurJarClassPathArray[loop] = x1; //build an array of class

    // OurClassPath =
            // new URL[] {
            // new URL("file:" +
ourProgramDirectory+File.separator + "DetailReports.jar") };

if you are still stuck, ask and I will post a full class, as i work on osx
