Problema em upload de arquivo

Pessoal, boa tarde!

Estou implementado um exemplo que vi em um livro e estou me deparando com a seguinte exception ao fazer o upload do arquivo para C:\123data:

java.io.FileNotFoundException: C:\123data (Acesso negado)

Segue o código do meu jsp:

String savePath="C:/123data/";

String filename= "";

ServletInputStream in = request.getInputStream();

byte[] line = new byte[128];
int i = in.readLine(line, 0, 128);
int boundaryLength = i - 2;
String boundary = new String(line, 0, i);

while(i != -1) {
	String newLine = new String(line, 0, i);
	if(newLine.startsWith("Content-Disposition: form-data; name=\"")); {
		String s = new String(line, 0, i-2);
		int pos = s.indexOf("filename=\"");
		if(pos != -1) {
			String filepath = s.substring(pos+10, s.length()-1);
			pos = filepath.lastIndexOf("\\");
			if(pos != -1)
				filename = filepath.substring(pos + 1);
			else
				filename = filepath;
		}
		
		i = in.readLine(line, 0, 128);
		i = in.readLine(line, 0, 128);
		
		i = in.readLine(line, 0, 128);
		
		ByteArrayOutputStream buffer = new ByteArrayOutputStream();
		newLine = new String(line, 0, i);
		
		while(i != -1 && !newLine.startsWith(boundary)) {
			buffer.write(line, 0, i);
			i = in.readLine(line, 0, 128);
			//newLine = new String(line, 0, i);
		}
		
		try {
			RandomAccessFile f = new RandomAccessFile(savePath + filename, "rw");
			byte[] bytes = buffer.toByteArray();
			f.write(bytes, 0, bytes.length-2);
			f.close();
		} catch(Exception e) {
			e.printStackTrace();
		}
		i = in.readLine(line, 0, 128);
	}
}

PS: Já tentei alterar a linha

String savePath="C:/123data/";

para

String savePath="C:\\123data\\";

e não parece ajudar. As permissões já foram todas liberadas, tenho dúvidas se o problema está na permissão do diretório ou no caminho que o buffer envia os dados:

try {
			RandomAccessFile f = new RandomAccessFile(savePath + filename, "rw");
