AWS Transcribe S3 .wav file to text - java

I am trying to use aws Transcribe to convert a wav file to text. I have uploaded a wav file to S3, which is located here and it has public read/write permissions: https://s3.us-east-1.amazonaws.com/csld8xmsdksdf8s9sk3mmdjsdifkjksdijsldk/Transcribe2.wav. The wav file is valid. I can download it in my browser and replay it (and it sounds like the origin recording), so I think we can rule out an invalid input file, file permissions, etc.
I am using java version: 1.8.0_275 for mac.
I expect my program to give me back the transcribed text: "Hello amazon Subscribe, what is this?"
Here is the actual program output, including exception:

I had a small mistake in my code. This line wasn't necessary and when I removed, it worked:
withEndpointConfiguration(new AwsClientBuilder.EndpointConfiguration(mediaFile, "us-east-1"))

How to replace specific line only on 1st occurence by mentioning keyword

I have below pom.xml file. I want to replace the version of the project which is in line 7.
I will be able to provide<version> tag alone but not complete version details.
Expecting a code which finds the 1st <version> tag line and replace that with <version>1.0.1</version>
I started with the below java code but which is currently replacing the whole version tag in the entire pom.xml.
How do I replace 1st <version> tag line alone with <version>1.0.1</version>

I suggest that you read file "pom.xml", line by line. If the line read is the line you want to change, then change it otherwise leave it as it is. Then write the line that you read to a temporary file. Once you have read all the lines in file "pom.xml", delete it and rename the temporary file to "pom.xml".
The below code does this.
import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.IOException;
import java.nio.file.Files;
import java.nio.file.Path;
import java.nio.file.StandardOpenOption;
public class OverwriteLine {
public static void main(String[] args) {
Path sourcePath = Path.of("pom.xml");
Path targetPath = Path.of("tmp.xml");
boolean error = false;
try (BufferedReader br = Files.newBufferedReader(sourcePath);
BufferedWriter bw = Files.newBufferedWriter(targetPath,
StandardOpenOption.CREATE,
StandardOpenOption.TRUNCATE_EXISTING,
StandardOpenOption.WRITE)) {
boolean found = false;
String line = br.readLine();
while (line != null) {
if (!found) {
if (line.trim().startsWith("<version>")) {
found = true;
line = line.replace("1.0.0", "1.0.1");
}
}
bw.write(line);
bw.write(System.lineSeparator());
line = br.readLine();
}
}
catch (IOException xIo) {
error = true;
xIo.printStackTrace();
}
if (!error) {
try {
Files.delete(sourcePath);
Files.move(targetPath, sourcePath);
}
catch (IOException xIo) {
xIo.printStackTrace();

Getting some issue like Cleaning up unclosed ZipFile for archive in excel file when run the Automation code

So I've been working on a simple automation framework that uses excel as data pool. However, while updating the version of my pom.xlm, I've encountered this error in my console:
Cleaning up unclosed ZipFile for archive D:\ExcelData\RPC Standard Form Data1.xlsx
I have no idea what went wrong. This error does not stop the execution and my tests run smoothly. How can I possibly solve this problem. I can't find anything suitable answers

Can't import ZKStringSerializer$

I want to create kafka topic in Java. I have a sample code from stackoverflow. But the problem is that I couldn't import ZKStringSerializer$ and ZkUtils. I have all maven dependencies. What is the reason? Her is the code:
import kafka.admin.AdminUtils;
import kafka.utils.ZKStringSerializer$;
import kafka.utils.ZkUtils;
import org.I0Itec.zkclient.ZkClient;
import org.I0Itec.zkclient.ZkConnection;
public class CreateKafkaTopic {
public static void main(String[] args) {
ZkClient zkClient = null;
ZkUtils zkUtils = null;
try {
String zookeeperHosts = "192.168.20.1:2181"; // If multiple zookeeper then -> String zookeeperHosts = "192.168.20.1:2181,192.168.20.2:2181";
int sessionTimeOutInMs = 15 * 1000; // 15 secs
int connectionTimeOutInMs = 10 * 1000; // 10 secs
zkClient = new ZkClient(zookeeperHosts, sessionTimeOutInMs, connectionTimeOutInMs, ZKStringSerializer$.MODULE$);
zkUtils = new ZkUtils(zkClient, new ZkConnection(zookeeperHosts), false);
String topicName = "testTopic";
int noOfPartitions = 2;
int noOfReplication = 3;
Properties topicConfiguration = new Properties();
AdminUtils.createTopic(zkUtils, topicName, noOfPartitions, noOfReplication, topicConfiguration);
} catch (Exception ex) {
ex.printStackTrace();
} finally {
if (zkClient != null) {
zkClient.close();
}
}
}
}

I assume you copied from this post? If so, read the very top of that accepted answer.
Zookeeper is a deprecated method to create topics.
Use AdminClient.createTopics or a higher-level framework like dropwizard-kafka configuration or spring-kafka's #Bean to create topics
Also, use kafka-clients dependency, not the kafka_[scala.version] depdendency

GZIP not working with Protocol Buffer. Snappy does

I am learning Protocol Buffer in Java. After basic serialization/deserialization, I am attempting to put compression.
In the provided code, I tried to use GZIP but while deserializing, it reads one extra record. It can be seen in System.out printing an extra "," at end.
This problem does not happen when using same code, but with Snappy (Commented in code below). Any suggestions if I am doing something wrong? Or if I can bypass the problem.
Output with GZIP:
id0,NAME0
,
Output with Snappy:
id0,NAME0
Code:

/*OutputStream os = new SnappyOutputStream(new BufferedOutputStream(new FileOutputStream(fileNm)))*/) {

DataClassProtoBufProxy.DataClass.Builder bld = DataClassProtoBufProxy.DataClass.newBuilder();
bld.setId(dc.id);
bld.setName(dc.name);

java.nio.channels.ClosedChannelException HTTP/2 with jetty

I am trying to use HTTP/2 to send an apple notification to my device on production.
I am passing this -Xbootclasspath/p:/home/mohamed/Desktop/alpn-boot-8.1.9.v20160720.jar as a Default VM arguments in eclipse.

// APNs requires the use of HPACK (header compression for HTTP/2), which prevents repeated header keys and values.
KeyStore ks = KeyStore.getInstance("PKCS12");
// Ensure that the password is the same as the one used later in setKeyStorePassword()
ks.load(PushNotifications.class.getClassLoader().getResourceAsStream("Prod2.p12"), "a12B34".toCharArray());
SslContextFactory ssl = new SslContextFactory(true);
ssl.setKeyStore(ks);
ssl.setKeyStorePassword("a12B34");
// create a high-level Jetty client
HttpClient client = new HttpClient(new HttpClientTransportOverHTTP2(lowLevelClient), ssl);
client.start();

but when i run this method from main method, it throws java.nio.channels.ClosedChannelException
Also i got this in eclipse console

Any idea?
Thanks
