Trying to read external file from ARIS report script

Hi Allen,

Hope this helps you

function getBytesFromFile(inputPath, inputFile) {
    var file = java.io.File(inputPath, inputFile);
    var fileInputStream = java.io.FileInputStream(file);
    var byteArrayOutputStream = java.io.ByteArrayOutputStream();
    while (fileInputStream.available()) {
        byteArrayOutputStream.write(fileInputStream.read());
    }
    var bytes = byteArrayOutputStream.toByteArray();
    fileInputStream.close();
byteArrayOutputStream.flush();
    byteArrayOutputStream.close();
    return bytes;
}

Thank You Amol!  This works perfect!

I was able to come up with my own solution below, but yours seems cleaner.  I ended up looping and reading one byte at a time.  Problem with ARIS script is not being able to define data type and size.

function getBytesFromFile(inputPath, inputFile){
    // Define file object to store file info
    var file = new java.io.File(inputPath, inputFile);
    // Define array to store byte array info for data 
    var bytes = new Array();
    // Define data input stream object that we will read
    var is = new java.io.DataInputStream(new java.io.FileInputStream(file));
    // Loop to read each byte from file until the end of file
    for (var index = 0; index < file.length(); index++) {
        bytes[index] = is.readByte();
    }
    return bytes;
}

Hello,

After I read the file, I wish to delete it from the network directory.  I thought it would be easy enough to do:

file.delete();

But that does not work in ARIS script.  I even tried just to rename it to some other filename, but that method doesn't seem to work either.

Is this possible to do from within a report script?

Hi Allen,

Try using

Context.deleteFile(filepath);

Make sure you have delete access to that network location.

Thanks,
