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();
}
}
}
}
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"))
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:

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.

// create a low-level Jetty HTTP/2 client
HTTP2Client lowLevelClient = new HTTP2Client();
lowLevelClient.start();
// 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();
// request-response exchange
ContentResponse response = client.POST("https://api.push.apple.com").path("/3/device/19297dba97212ac6fd16b9cd50f2d86629aed0e49576b2b52ed05086087da802")

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

Last thing, here are jars i used in my project:
I need to convert JPEG images to MPEG video and to be able to easily set the duration that each frame displayed.
I have tried JMF, Xuggler, & JCodec but all have their problems.
I will appreciate any solution that is well explained for either JMF , Xuggler, JCode, or even JavaCV(Have not tried this).
Below are my coding attempts.

JCodec Attempt (jCodecJpegImagesToMpegVideo.java):
With jCodec I had 2 approaches first using the built in org.jcodec.api.SequenceEncoder and later based on other posts online creating my own SequenceEncoder class called MySequenceEncoder, because the org.jcodec.api.SequenceEncoder did not have any methods to set duration on each frame.

Issue - Whether using SequenceEncoder.java or MySequenceEncoder.java the video that gets created doesnt play, there are no errors either, the video opens but nothing is displayed.
I'm also unable to figure what are correct parameters to pass into:
outTrack.addFrame(new MP4Packet(result,25,1,1,frameNo,true,null,1,0));
Again a working JMF, Xuggler, JCodec , or JavaCV solution , with full instructions & dependency information will be greatly appreciated.
Thank you all in advance.
I finally got a working solution that converts JPEG images into MPEG extension ".mp4" video using the Xuggler library:
