Question

The following code is giving me this error:

java.lang.NullPointerException
java.io.FileOutputStream.(Unknown Source)
java.io.FileOutputStream.(Unknown Source)
java.io.FileWriter.(Unknown Source)

SAXBuilder parser = new SAXBuilder();
this.document = parser.build(path);

//changes on the doc happening here

FileWriter writer = new FileWriter(path);
XMLOutputter out = new XMLOutputter();
out.output(this.document, writer);
writer.flush();
writer.close();

How come? It the file locked or something?

On a sidenote: What is the advantage of using BufferedOutputStream classes?

Answer 1

The issue was a wrong path to the file, like suggested.
