The Processing Instruction Target Matching “[xX][mM][lL]” is Not Allowed
Friday, June 24th, 2011
Background
When parsing XML you receive the following error:
...The Processing Instruction Target Matching "[xX][mM][lL]" is Not Allowed...
Solution
The chances are you have some sort of whitespace (or control character) infront of your XML declaration:
..<?xml version="1.0" encoding="utf-8"?>
It may even be that you have more than one XML declaration in the document..!

Read a File as String with Java
Thursday, June 16th, 2011
Introduction
I’m always Googling for a way to do this. This seems to be the best “idiomatic” solution I’ve found. So without further ado…
Example
public String readFile(String path) throws IOException {
FileInputStream stream = new FileInputStream(new File(path));
try{
FileChannel fc = stream.getChannel();
MappedByteBuffer bb = fc.map(FileChannel.MapMode.READ_ONLY, 0, fc.size());
return Charset.defaultCharset().decode(bb).toString();
}
finally {
stream.close();
}
}
