I'm trying to produce and consume blob(pdf) and stream(log ) file from message queue using java(jms).After googling ,i found that ActiveMQ support Blob message.I tried to implement using ActiveMQ. But there is no complete solution or example over the internet.
Could you please help me by giving sample code (with proper broker url) or how to do this? Also is there any other MQ that support Stream & Blob messages?
Default url should be like this:
tcp://localhost:61616?jms.blobTransferPolicy.defaultUploadUrl=http://localhost:8161/fileserver/
If you need a complete code solution,please go through this link below:

There are several messages from producer that I receive and I need to store them in to the stream but I don't want to do it manually from ksqldb console and need to handle those insertions via programming (Python/Java). Could anybody show me a sample code or any reference?
Thanks!
you can use the REST APIs or the Java client to interact with ksqlDB. Here's the doc for Java client with code snippet for insert: https://docs.ksqldb.io/en/latest/developer-guide/ksqldb-clients/java-client/#stream-inserts.
In an earlier post from a few minutes ago, I asked a "general" question regarding creating general webservices in vaadin: How can one create webservices in Vaadin 12?
However, one specific unique case that I mainly need to support is the uploading via https of large (eg ~400MB) bytestream objects that would presumably be sent to Vaadin via an https "post" command (with the paylod being provided I presume in raw binary format as a bytestream.) I saw that Vaadin has built-in support for uploading files (which is essentially a post command of a bytestream, I presume?) and then I saw a reference to StreamReceiver here: https://vaadin.com/docs/v12/flow/advanced/tutorial-stream-resources.html
which seems to sound like a custom file importer, but I couldn't find any (simple & more-or-less complete) examples on how to use it. Ideally, a quick few lines of Java to show the "receiving" of the bytestream and a few quick lines (ideally in Java) which "posts" to the receivestream's url would be all that's needed to show how this manual upload of bytes can be accomplished in Vaadin. (In DropWizard & Jersey, I can find such examples reasonably easily, but I'm not sure how to gain that level of control in Vaadin.)
(Very very minor bonus: is there a size limit to the post command? eg, can a bytestream of over say ~4GB be sent and received?)
In Vaadin the Upload API is optimised for streaming into File (unlike handling the stream as in Servlet and JAX-RS API). One way is to first stream to a temp file and then when the file is fully on the server side, handle the data from temp file.
Alternatively you can use Flow Viritin add-on and a helper class UploadFileHandler, which give you and API where you read the contents from InputStream, in same way as with Servlet API. See a usage example is in this test.
This isn't a first time this is asked and I actually have a more verbose blog draft about this subject. I'll add a link to that once I get that published.
I'm using HL7Soup as my HL7 Client to add a new patient record to no avail. Can anyone help me fix an error I received? I have checked HL7 manual on the net, it didn't help as it is very unreliable.
I sent the following message using the client:
MSH|^~\&|HL7Soup|Instance1|HL7Soup|Instance2|20160928142250|1|ADT^A28|0000000|D|2.5.1|1|2|||||||2

And got the following response:

I don't know which field it's trying to refer to. I checked the manual it suggests 'Visit Number', I changed it, but still had the error. Help Pls.
Thanks in advance.
I think you try to send an ADT message to a system that is configured to receive order (ORM) messages.
The answer you get is an ORR^O02 (a reply to an order message).
The answer requests an accession number. Those are typically used in order entry not in ADT.
You did provide a visit number (PV1-19): 0
Maybe you use the wrong system or the wrong port?
To connect to a remote system I would recommend that you use a library like HAPI (http://hl7api.sourceforge.net) or something like Apache Camel (http://camel.apache.org/hl7) or Mirth Connect. There are many pitfalls in MLLP (the protocol usually used).
I am dealing with a bad connection to an external IMAP server. I need my application to download messages from this mail server periodically. On many occasions, my code has already downloaded message using javamail and has executed message.getContent and is then processing individual body parts (attachments). While it is in the process of doing this, the connection can drop.
I need to thus make sure that messages are not marked as SEEN automatically on doing message.getContent, which is how Javamail behaves, as described in this reply here:
https://stackoverflow.com/a/7679091/303106
Is there any way to make sure messages that were not downloaded are not marked as SEEN?
Message msg = ...;
((IMAPMessage)msg).setPeek(true);
Yes, use the BODY.PEEK instead of just BODY when fetching the data, and/or use EXAMINE instead of SELECT to open a mailbox. I'll leave it as an excercise to the reader to read the javamail's documentation to see how these options relate to the features provided by the havamail.
I've a file I want to send to the ebay system to support the LMS.
All the samples I've found include the use of the API, but the environment I'm working in doesn't have the ability to use it (the api).
So I'm forced to send the file with an HTTP post. But the doc's seem lacking.
Has anyone constructed/found an example of a HTTP post that will send a given file.
EDIT:
Oh.. what I see in the samples I have found is an area that seems it's supposed to have the data, but in the sample, there's nothing I'd consider real data.
Are you talking about the file transfer service or the bulk upload service? Don't you just generate an xml document and post the url like in this example:
