Help me please if you can)
I am trying to use google speech to text API. I have uploaded an audio file ( record1638730550724.wav) on google storage bucket with the name "summaryapp". But when i try to make longrecognize request i get this error

When I test to drop a file to SFTP server in local it worked as I expected in Sucess Request because the process to upload seemed fast because it is in local (FileZilla).
But when I test to drop a file again to SFTP server that hosts in real server sometimes it works and sometimes it didn't work Fail Request. Seem like the SFTP consuming file issue. Could you please help me on that? Thanks
The file is probably (sometimes) consumed by your Camel route before the file upload is finished.
What you can try is to configure your endpoint to poll the files only if it has exclusive read-lock on the file (i.e. the file is not in-progress or being written); see the readLock parameter.
I think the default is no read lock; you should set readLock=changed...but I do not remember is such mode is also possible on endpoints of SFTP type.
I need to test some REST client. For that purpose I'm using org.mockserver.integration.ClientAndServer
I start my server. Create some expectation. After that I mock my client. Run this client. But when server receives request I see in logs:

Looks like I miss some server configuration, or use it in wrong way.
Or, maybe the reason is in powermock: could it be that mockserver is incompatible with powermock or PowerMockRunner?
I have a Spring Boot project that is leveraging Spring Integration. My goal is to to poll a POP3 mail server regularly, and download any attachments associated with those messages. My relevant Spring Config looks like this:
#Configuration
public class MailIntegrationConfig {
#Value("${path.output.temp}")
private String outPath;

var receiver = new Pop3MailReceiver("pop3s://user:passwordexample.com/INBOX");
var mailProperties = new Properties();
mailProperties.setProperty("mail.pop3.port", "995");
mailProperties.put("mail.pop3.ssl.enable", true);
receiver.setShouldDeleteMessages(false);
receiver.setMaxFetchSize(10);
receiver.setJavaMailProperties(mailProperties);
// receiver.setHeaderMapper(new DefaultMailHeaderMapper());
var source = new MailReceivingMessageSource(receiver);
return source;
}
#Bean
#ServiceActivator(inputChannel = "mailChannel")
public MessageHandler popMessageHandler() {
return new MailReceivingMessageHandler(outPath);
}
}
My MailReceivingMessageHandler class (partial)
public class MailReceivingMessageHandler extends AbstractMessageHandler {
private String outDir;
public MailReceivingMessageHandler(String outDir) {
var outPath = new File(outDir);
if (!outPath.exists()) {
throw new IllegalArgumentException(String.format("%s does not exist.", outDir));
}
this.outDir = outDir;
}

}
try {

} else if (cType.contains(MediaType.MULTIPART_MIXED_VALUE)) {

}
}

FilenameUtils.getExtension(part.getFileName()));
FileUtils.copyInputStreamToFile(part.getInputStream(), new File(outDir + File.separator + fName));
}
if (content instanceof Multipart) {
Multipart multipart = (Multipart) content;
for (int i = 0; i < multipart.getCount(); i++) {
var bodyPart = multipart.getBodyPart(i);
processAttachments(bodyPart);
}
}
}
}
}

Obviously, the root cause is clear - the POP3 folder is closed. I have seen solutions that would likely be able to handle when just the Java mail classes are used, but none with Spring Integration. My question is how does one properly control when a folder is open or closed using Spring Integration Mail? I realize the Pop3MailReceiver class has a .setAutoCloseFolder() method. Based on the Spring Docs, I assume I need to set that, along something like the following to my handler:
Closeable closeableResource = StaticMessageHeaderAccessor.getCloseableResource(message);
if (closeableResource != null) {
closeableResource.close();
}
However, if I set autoCloseFolder to false, it does not appear as if the message even ever "hits" my handler, so unfortunately being able to close the resource does not even matter at this point. That is, when autoClose is set to false, the 'handleMessageInternal()' method in my handler class is never reached even though there are indeed message on the POP3 server. Instead I just get a bunch of logs like this:
2020-06-26 15:26:54.523 INFO 15348 --- [ scheduling-1] o.s.integration.mail.Pop3MailReceiver : attempting to receive mail from folder [INBOX]
What am I missing?
Thanks.

For Android, you have to store the service account file either in the assets folder or raw folder.
This thread provides code on a number of ways to load the json data into an InputStream depending on the location you selected.
I have my Hyperledger Fabric V1.0 network up and running by following the steps Building Your First Network.
And now I am able to create channel, install/instantiate/invoke/query chaincode etc.
Now I am trying to create some assets and query the same using Java SDK Client.
I have created the following methods to invoke and query the chaincode from my java application.
void createChannel() throws InvalidArgumentException, TransactionException, IOException, ProposalException{
Properties ordererProperties = getOrdererProperties("orderer.example.com");
ordererProperties.put("grpc.NettyChannelBuilderOption.keepAliveTime", new Object[] {5L, TimeUnit.MINUTES});
ordererProperties.put("grpc.NettyChannelBuilderOption.keepAliveTimeout", new Object[] {8L, TimeUnit.SECONDS});
Orderer orderer = client.newOrderer("orderer.example.com", "grpcs://192.168.99.100:7050",ordererProperties);
Properties peerProperties = getPeerProperties("peer0.org1.example.com"); //test properties for peer.. if any.
if (peerProperties == null) {
peerProperties = new Properties();
}
peerProperties.put("grpc.NettyChannelBuilderOption.maxInboundMessageSize", 9000000);
Peer peer = client.newPeer("peer0.org1.example.com", "grpcs://192.168.99.100:7051",peerProperties);
channel = client.newChannel("testchannel");
channel.addOrderer(orderer);
channel.addPeer(peer);
channel.initialize();
}
void creteTransactionalProposal(){
proposalRequest = client.newTransactionProposalRequest();
final ChaincodeID chaincodeID = ChaincodeID.newBuilder()
.setName("asset_test")
.setVersion("1.0")
.setPath("github.com/myuser/myfabricrepo/asset_chain")
.build();
proposalRequest.setChaincodeID(chaincodeID);
proposalRequest.setFcn("set");
proposalRequest.setProposalWaitTime(TimeUnit.SECONDS.toMillis(1));
proposalRequest.setArgs(new String[]{"a1", "a1_val"});
}
void sendProposal() throws ProposalException, InvalidArgumentException, InterruptedException, ExecutionException{
final Collection<ProposalResponse> responses = channel.sendTransactionProposal(proposalRequest);
CompletableFuture<BlockEvent.TransactionEvent> txFuture = channel.sendTransaction(responses, client.getUserContext());
BlockEvent.TransactionEvent event = txFuture.get();//waiting indefinitely
System.out.println(event.toString());
//query();
}
void query() throws InvalidArgumentException, ProposalException{
final ChaincodeID chaincodeID = ChaincodeID.newBuilder()
.setName(""asset_test"")
.setVersion("1.0")
.setPath("github.com/myuser/myfabricrepo/asset_chain")
.build();
QueryByChaincodeRequest queryByChaincodeRequest = client.newQueryProposalRequest();
queryByChaincodeRequest.setArgs(new String[] {"a1"});
queryByChaincodeRequest.setFcn("get");
queryByChaincodeRequest.setChaincodeID(chaincodeID);
Map<String, byte[]> tm2 = new HashMap<>();
tm2.put("HyperLedgerFabric", "QueryByChaincodeRequest:JavaSDK".getBytes(UTF_8));
tm2.put("method", "QueryByChaincodeRequest".getBytes(UTF_8));
queryByChaincodeRequest.setTransientMap(tm2);
Collection<ProposalResponse> queryProposals = channel.queryByChaincode(queryByChaincodeRequest, channel.getPeers());
for (ProposalResponse proposalResponse : queryProposals) {
if (!proposalResponse.isVerified()
|| proposalResponse.getStatus() != ProposalResponse.Status.SUCCESS) {
System.out.println("Failed query proposal from peer " + proposalResponse.getPeer().getName() + " status: "
+ proposalResponse.getStatus() + ". Messages: " + proposalResponse.getMessage()
+ ". Was verified : " + proposalResponse.isVerified());
} else {
String payload = proposalResponse.getProposalResponse().getResponse().getPayload()
.toStringUtf8();
System.out.printf("\nQuery payload of b from peer %s returned %s", proposalResponse.getPeer().getName(),
payload);
//assertEquals(payload, expect);
}
}
}
I am able to create Asset by calling
t.creteTransactionalProposal();
t.sendProposal();
But the line BlockEvent.TransactionEvent event = txFuture.get(); makes the application in an indefinite waiting state even after the completion of the transaction commit to ledger. Why it is behaving like this?
Once I to force exit and run the query() method it is listing the asset.
I ran into a similar issue to this, and many of the answers around the net are missing a key part of the code - assigning the EventHub to the channel. I added this before initializing the channel (which in this case would be in the createChannel mehtod), and my transactions were then processed successfully:
channel.addEventHub(client.newEventHub("eventhub0", "grpc://localhost:7053"));
