I have a bunch of xml files in a directory. I do not know the names nor do I know the number of files.  How do I obtain FileInputStreams to each of these files.  i.e., Suck in all *.xml files in a given directory. Then create a FileInputStream for each.

How do I do this?  I need this to work on both Solaris and Windows..

Thanks

you can get a listing of the files using this:

java.io.File dir = new java.io.File("/path/to/directory");
java.io.Files[] fileList;
int xmlfilecount = 0;
if (dir.isDirectory()) {
  java.io.File[] tempList = dir.listFiles();
  for(int i=0; i<tempList.length;i++) {
        if(!tempList [i].isDirectory()) {
          fileName = tempList [i].getName();
          if (fileName.toUpperCase().endsWith(".XML")) {
            fileList[xmlfilecount++] = (java.io.File) tempList[i].clone();
          }  
        }
  }
}

now you can iterate through the fileList array and create input streams for each one.

There is a way to deal with unix vs windoze file paths.. I will look into that.. but this should get you started.

File.separatorChar is the what you can use to switch btw "/" and "\"
