Write resource within war file on AWS s3

Hello, how do I record a resource that is inside a war structure, generated by the deploy of the java application, in the AW3 S3.

The method below works when the application is on the local server, but when I deploy through ElasticBEanastalk, the same application does not write.

public void loadFile(byte[] foto, String id, String url)  {
    try {

        Path path = Paths.get(url + id + ".jpg");
        Files.deleteIfExists(path); 

        InputStream initialStream = new ByteArrayInputStream(foto);
        byte[] buffer = new byte[initialStream.available()];
        initialStream.read(buffer);
        File targetFile = new File(url + id + ".jpg");
        OutputStream outStream = new FileOutputStream(targetFile);
        outStream.write(buffer);
        outStream.close();
    } catch (IOException e) {
        e.printStackTrace();
        System.out.println("Impressao do StackTrace do erro de envio de email: "+e.toString());
    }
}

I discovered and tested the AmazonS3 api, shown below, which writes a file into a folder in the root of the bucket, but does not figure out how to write to a folder inside the war file.

public void loadFile(byte[] foto, String id, String url)  {
    try {

    AWSCredentials credentials = new BasicAWSCredentials("AKIvJXEtttEIGOVDX3E6Q","a33aLafwtttttXyJTITEUJSTP6DCfruqTxabgI");
        AmazonS3Client amazonS3Client = new AmazonS3Client(credentials);
        AmazonS3 s3 = new AmazonS3Client(credentials);
         s3 = AmazonS3ClientBuilder.standard().withRegion(Regions.SA_EAST_1)
                    .withCredentials(new AWSStaticCredentialsProvider(credentials)).build();
                    s3.putObject(new PutObjectRequest("elasticbeanstalk-sa-east-1-122554548526", id + ".jpg", new File(url + id + ".jpg")));

Thanks, if anyone has a suggestion to solve the problem.
