I am a beginner using S3 and I want to use it to store certain files of my computer. I wrote a small program in Java that uploads all my files and folders but I have this exception :
Infos: Received error response: Status Code: 403, AWS Request ID: F75DC5496B071F7D, AWS Error Code: SignatureDoesNotMatch, AWS Error Message: The request signature we calculated does not match the signature you provided.

I am sure I provided the correct credentials to the SDK. I used the same credentials from a previous program for testing purposes and it worked. It's possible for me to create buckets but I am unable to store objects in it. In my code, I use the PutObjectRequest
to store objects.
Here's how I init my amazon S3 object :
AmazonS3 s3 = new AmazonS3Client(new PropertiesCredentials(
S3Export.class .getResourceAsStream("AwsCredentials.properties")));
The uploading code :
private void parseDirectory(File fin, File fdefault, String out)
throws FileNotFoundException {
System.out.println("processing .." + fin.getName());
File[] files = fin.listFiles();
PrintWriter pw = new PrintWriter(fdefault);
for (File f : files) {
String key = UUID.randomUUID().toString();
String name = "";
PutObjectRequest por = null;
if (f.isDirectory()) {
name = "d_" + f.getName() + ".properties";
File metadata = new File(out + name);
parseDirectory(f, metadata, out);
pw.println(key + "=" + name);
//upload to s3
por = new PutObjectRequest(this.bucketName, key, metadata);
} else {
name = f.getName();
pw.println(key + "=" + name);
por = new PutObjectRequest(this.bucketName, key, f);
}
this.amazonS3.putObject(por);
}
pw.close();
}
My code fails in this line : this.amazonS3.putObject(por);
.
Can somebody explain what is wrong with my code.

I finally find the anwer to my question. The truth is in the initialization, I passed a wrong bucket name and I am using a different name for making the requests. That's all.
