Hi am trying to download .zip file from firebase storage using code
FirebaseStorage httpsReference = FirebaseStorage.getInstance();
StorageReference reference = httpsReference.getReferenceFromUrl(Constants.FIREBASE_ST_URL);
StorageReference referenceNew = reference.child("ImageSets").child(post.get("SetName") + ".zip");
Log.d("log_tag", "ZIP URL referenceNew : " + referenceNew.toString());
//**this is log result** gs://memory-matcch.appspot.com/ImageSets/set_2.zip
referenceNew.getFile(file).addOnSuccessListener(new OnSuccessListener<FileDownloadTask.TaskSnapshot>() {
#Override
public void onSuccess(FileDownloadTask.TaskSnapshot taskSnapshot) {
Log.d("log_tag", "ZIP FILE onSuccess : " + Uri.fromFile(file) + "\nPath : " + file.getPath() + "\nAbsolute : " + file.getAbsolutePath());
}).addOnFailureListener(new OnFailureListener() {
#Override
public void onFailure(#NonNull Exception e) {
}
});
and this is fire base rule
this is firebase storage
and I am getting this error
Exception occurred during file download

I want to do this without login in fire base as I ant that user can download zip without login also.
.getFile(file) seems to be your problem--what is file? This download the zip to your local filesystem, and it appears, as the exception states, "No such file or directory".
Try getBytes() or getStream() to download in memory, or pick a valid file to write to.
You just need to provide two-arguments first File or second Name in which you want to give that file
Like:
storageRefrence.getFile(fileDirectory, fileName).addOnCompleteListener(new ...);

I have the below code that I want to read all music in downloads but it's giving the above error. What can be the problem
final dartFile = Glob("/storage/emulated/0/Download/**.mp3");
for (var entity in dartFile.listSync()) {
print(entity.uri);
}
Below is my manifest file
I have a JAR file with below structure:
example.jar
|
+-org
| +-springframework
| +-boot
| +-loader.jar
+-BOOT-INF
+-classes
| +- kafka
| truststore.jks ==> I want to get the path here
+-lib
+-dependency1.jar
How can I get the configuration file path, only path (string) of 'kafka/truststore.jks' file ?
Because I am applying the SSL for KafkaProducer, I using below code and it work fine on local:
#Value("classpath:kafka/truststore.jks")
private org.springframework.core.io.Resource sslTruststoreResource;
...
String sslTruststoreLocation = sslTruststoreResource.getFile().getAbsolutePath(); // ==\> ***it throw FileNotFoundException here on deployed Server, local env run fine !***
Map\<String, Object\> config = Maps.newHashMap();
config.put("ssl.truststore.location", sslTruststoreLocation);
but when I deploy on Server, it throw FileNotFoundException :(
After many days to research, I found that the sslTruststoreResource.getFile() will be fail for JAR file case as mentioned at here
The sslTruststoreResource.getInputStream() or sslTruststoreResource.getFilename() are ok for JAR file but they are not path I need for kafka configuration.
In my project, the 'truststore.jks' file is located as below:
src
-- java
-- resources
. -- kafka
-- truststore.jks
So, is there any solution for my issue ? Thank you.
I tried to use ClassPathResource, ResourcePatternResolver but they not working
After many ways I still could not get the path from JKS file then I copy it to another path out of jar file where my code can refer to its path
final String FILE_NAME = env.getProperty("kafka.metadata.ssl.truststore.location");
String sslTruststoreLocation = "*-imf-kafka-client.truststore.jks";
try {
InputStream is = getClass().getClassLoader().getResourceAsStream(FILE_NAME);
// Get the destination path where contains JKS file
final String HOME_DIR = System.getProperty("user.home");
final Path destPath = Paths.get(HOME_DIR, "tmp");
if (!Files.isDirectory(destPath)) {
Files.createDirectories(destPath);
}
// Copy JKS file to destination path
sslTruststoreLocation = destPath.toFile().getAbsolutePath() + "/" + FILE_NAME;
File uploadedFile = new File(sslTruststoreLocation);
if(!uploadedFile.exists()) {
uploadedFile.getParentFile().mkdirs();
uploadedFile.createNewFile();
FileCopyUtils.copy(is, new FileOutputStream(sslTruststoreLocation));
log.debug("Copied {} file from resources dir to {} done !", FILE_NAME, sslTruststoreLocation);
}
config.put(SslConfigs.SSL_TRUSTSTORE_LOCATION_CONFIG, sslTruststoreLocation);
} catch (IOException e) {
final String message = "The " + sslTruststoreLocation + " file not found to construct a KafkaProducer";
log.error(message);
}
Looks like this is a known issue in Kafka.
Spring Boot propose a workaround similar to yours.
I’m trying to download several files from a local network device:
http file directory
I want to write a code that will automatically download all those .avi files to my pc drive.
I have 2 problems:
Problem 1: AUTHENTICATING using WebClient class only.
If I use WebClient class only to connect, I get a 401 Unauthorized error.
Code:
try
{
using (WebClient myWebClient = new WebClient())
{
myWebClient.UseDefaultCredentials = false;
myWebClient.Credentials = new NetworkCredential("user", "pword");
String userName = "user";
String passWord = "pword";
string credentials = Convert.ToBase64String(Encoding.ASCII.GetBytes(userName + ":" + passWord));
myWebClient.Headers[HttpRequestHeader.Authorization] = "Basic " + credentials;
Console.WriteLine("Header AUTHORIZATION: "+ myWebClient.Headers[HttpRequestHeader.Authorization].ToString());
// Download the Web resource and save it into the current filesystem folder.
Console.WriteLine("Start DL");
myWebClient.DownloadFile("http://192.168.2.72:81/sd/20170121/record000/P170121_000000_001006.avi", "P170121_000000_001006.avi");
Console.WriteLine("End DL");
}
}
catch(Exception ex)
{
Console.WriteLine("DOWNLOAD ERROR: " + ex.ToString());
}
Error Message: Failure to authenticate
401 Unauthorized Error
Problem 2: Was able to authenticate using WebProxy class but can’t download . Getting 403 Not found error.
Code:
try
{
using (WebClient myWebClient = new WebClient())
{
WebProxy wp = new WebProxy("http://192.168.2.72:81/sd/20170121/record000/",false);
wp.Credentials = new NetworkCredential("user","pword");
Console.WriteLine("Web Proxy: " + wp.Address);
myWebClient.UseDefaultCredentials = false;
myWebClient.Credentials = wp.Credentials;
myWebClient.Proxy = wp;
Console.WriteLine("Downloading File \"{0}\" from \"{1}\"\n\n", filename, wp.Address);
// Download the Web resource and save it into the current filesystem folder.
Console.WriteLine("Start DL");
myWebClient.DownloadFile("http://192.168.2.72:81/sd/20170121/record000/P170121_000000_001006.avi", "P170121_000000_001006.avi");
Console.WriteLine("End DL");
}
}
catch(Exception ex)
{
Console.WriteLine("DOWNLOAD ERROR: " + ex.ToString());
}
Error Message: 403 Not Found
DOWNLOAD ERROR: System.Net.WebException: The remote server returned an error: (404) Not Found.

Please help me identify if there are any mistakes in my code or is there a better way to submit credentials and download all the files.
Thanks in advance!
I'm not Dot Net developer, I'm just sharing my opinion.
In the second point you have mentioned that you are getting 403 which is the Http status code for Acces Denied. I feel your credentials are not valid or you don't have privilege to do the operation.
I am trying to read .xlsx file with rules using kie api 6.
However I get this exception

The code looks like this
try {
KieServices ks = KieServices.Factory.get();
KieFileSystem kfs = ks.newKieFileSystem();
kfs.write(ks.getResources().newInputStreamResource(Files.newInputStream(p, StandardOpenOption.READ)));
KieBuilder kb = ks.newKieBuilder(kfs);
if (kb.getResults().getMessages(Level.ERROR).size() != 0) {
logger.lifecycle("Invalid file: {}.", kb.getResults().getMessages());
return false;
}
} catch (Exception e) {
logger.lifecycle("UNEXPECTED ERROR DURING VALIDATION -------------- ", e);
return false;
}
logger.lifecycle("Valid file: {}.", p);
return true;
}
It fails on kfs.write by the way.
I also checked the path to file by displaying it in console
Attempt to process rule file: D:\PROJECT_FOLDER\project\src\testInteg\resources\rules\rule.xlsx
and it is a correct path.
What's the problem? I am using 6.3 Final version.
I recommend this mantra, assuming your String p contains the path name as shown:
FileInputStream fis = new FileInputStream( p );
kfs.write( "src/main/resources/rule.xslx",
kieServices.getResources().newInputStreamResource( fis ) );
There are some other forms for write to the KieFileSystem, but I find that this is easy to use. You may derive the rule.xslx from p, using Java's API for path names.
I'm creating my first gradle plugin. I'm trying to copy a file from the distribution jar into a directory I've created at the project. Although the file exists inside the jar, I can't copy it to the directory.
This is my task code:
import org.gradle.api.DefaultTask;
import org.gradle.api.tasks.TaskAction;
class InitTask extends DefaultTask {
File baseDir;
private void copyEnvironment(File environments) {
String resource = getClass().getResource("/environments/development.properties").getFile();
File input = new File(resource);
File output = new File(environments, "development.properties");
try {
copyFile(input, output);
}
catch (IOException e) {
e.printStackTrace();
}
}
void copyFile(File sourceFile, File destFile) {
destFile << sourceFile.text
}
#TaskAction
void createDirectories() {
logger.info "Creating directory."
File environments = new File(baseDir, "environments");
File scripts = new File(baseDir, "scripts");
File drivers = new File(baseDir, "drivers");
[environments, scripts, drivers].each {
it.mkdirs();
}
copyEnvironment(environments);
logger.info "Directory created at '${baseDir.absolutePath}'."
}
}
And this is the error I'm getting:
:init

Just to emphasize, the development.properties is inside the environments directory inside the MyJar.jar
getClass().getResource() returns a URL. To access that URL, you'll have to read it directly (e.g. with url.text) rather than first converting it to a String/File. Or you can use getClass().getResourceAsStream().text, which is probably more accurate. In both cases you can optionally specify the file encoding.
Kotlin DSL answer!
For cases like this it is good to have extensions:
fun Any.getResource(filename: String): File? {
val input = this::class.java.classLoader.getResourceAsStream(filename) ?: return null
val tempFile = File.createTempFile(
filename.substringBeforeLast('.'),
"." + filename.substringAfterLast('.')
)
tempFile.deleteOnExit()
tempFile.writer().use { output ->
input.bufferedReader().use { input ->
output.write(input.readText())
}
}
return tempFile
}
