Streaming Binary Data

Hi,
I would like to send plain old binary data using RTP. How can I use the JMF to send binary data without binding it to a codec or media type?
Thanks,

Thank u very much,
     FileOutputStream opGif = new FileOutputStream(destFile, false);
I have changed above line with the following line:
     PrintWriter opGif = new PrintWriter ( new FileWriter(destFile, false));
and now this code is working very fine.
Thanks once again...

Conversion of a binary data stream to decimal numbers

Hi
I am having great difficult working out how to convert my binary data stream to decimal numbers.
The data I am reading back is in the format of a binary string, starting with the Most Significant Bit (MSB) of the first word, then the corresponding Least Significant Bit (LSB), where a word is two bytes long. A carriage return indicates message termination. The return message starts with ‘bin,’ followed by the number of bytes requested. No delimiters are used to separate the data, but a carriage return is appended onto the end of the data.
bin,<first word msb><first word lsb>...<last word lsb><CR>
e.g. bin,$ro¬z1;@*...etc
Does anybody know of any examaple vi that can help me convert this data from binary to decimal numbers?
Many Thanks
Ash

Hi Ashley,
after getting the string you can strip the first 4 characters. After this try a typecasting to array of U16. If the numbers are not correct, you can add a swap bytes operation to the resulting array.

Data plug-in for binary data with byte streams of variable length

Hi there,
I would like to write a data plug-in to read binary data from file and I'm using DIAdem 10.1.
Each data set in my file consists of binary data with a fixed structure (readable by using direct access channels) and of a byte stream of variable length. The variable length of each byte stream is coded in the fixed data part.
Can anyone tell me how my data plug-in must look like to read such kind of data files?
Many thanks in advance!
Kind regards,
Stefan

Hi Brad,
thank you for the very quick response!
I forgot to mention, that the data in the byte stream can actually be ignored, it is no data to be evaluated in DIAdem (it is picture data and the picture size varies from data set to data set).
So basically, of each data set I would like to read the fixed-structure data (which is the first part of the data set) and discard the variable byte stream (last part of the data set).
Here is a logical (example) layout of my binary data file:
| fixedSize-Value1 | fixedSize-Value2 | fixedSize-Value3 (=length of byte stream) | XXXXXXXXXXXXX (byte stream)
| fixedSize-Value1 | fixedSize-Value2 | fixedSize-Value3 (=length of byte stream) | XXXXXX (byte stream)
| fixedSize-Value1 | fixedSize-Value2 | fixedSize-Value3 (=length of byte stream) | XXXXXXXXXXXXXXXXXXXX (byte stream)
What I would like to show in DIAdem is only fixedSize-Value1 and fixedSize-Value2.
´
If I understood right, would it be possible to set the BlockLength of each data set by assigning Block.BlockLength = fixedSize-Value3 and to use Direct Access Channels for reading fixedSize-Value1 and fixedSize-Value2 ?
Thank you!
Kind regards,
Stefan

Hi,
The pointer is a U32 that points to a memory location where the data is. It is not clear from the prototype whether the pointer points to data that is feeded to the dll, or returned from the dll.
If data is feeded, wire an array to this parameter, and set uFwLen to it's length.
If data is returned, you need to use some other api calls to get the data from memory...
Regards,
Wiebe.

Hi,
First you need to define your ext prog in SM69.

Writing binary data to ASP file from applet through URLConnection

Hi Everybody,
I am facing a proble with HttpURLConnection.I want to write some binary data from applet to an ASP file.The other end ASP file read this binary data and process , Here problem is I have opened URLConnection to the page and Created OutputStream and writing byte by Write() method But other end we are not getting bytes...we are not getting error too at java side..can any body help me..do we need to set any property to URLConnection...here I am giving sample code...

Do you remember to flush() and close() the stream?

How to output binary data to VISA

i am interfacing labview with pic microcontroller through serial port using VISA. it is a stream of digital data which is being tranmitted ,stored in microcontroller and then retransmiited by microcontroller to other device...problem is when that data is converted to string to be given to VISA it makes 16bytes out of 16bits...for example if data was "11110000" (1byte) after converted to string it becomes 8 bytes and my microcontroller thibk that 8 bytes are coming................ please kindly tell me how to transmit binary data over serial port so that bit remains a bit dont become byte............................ data is 99bytes but after passing through VISA it become "99x16"bytes........ please help me

The attached example in 8.0 converts a U16 into two U8, builds an array and with the Byte Array to String, converts to the hex string 8000 (two bytes). Note that the string indicator is configured for Hex Display (right click option).
Now, when you say you want to see '1000001 on the hyperterminal of other PC', you are contradicting yourself. Hyperterminal cannot be set for binary display so if you want to see '10000001' in Hyperterminal, then you need 8 bytes (one for each ASCII character).
I hope I have made myself clear.

Adapter development: binary data and adapter specific properties?

Hi,
We have succesfully developed our own SFTP adapter based on the J2SSH Maverick library (http://www.sshtools.com/showMaverick.do) and the sample file adapter that comes with XI.
There are 2 features we would like to implement as well, but lack the necessary documentation and sample code.
<b>1st Binary data</b>
We do not succeed in transporting binary data via our SFTP adapter (both text and xml go fine). While debugging, we see that the binary data are correctly picked up, but the actual payload appearing in message monitoring is much larger. When we write the message to a file again, the data have changed (size has e.g. increased importantly from 127180 bytes to 218198 bytes). According to the sample adapter code, the contenttype "application/octet-stream" should be specified. But the standard XI file adapter itself seems to specify "application/octet-stream".
<b>2nd Adapter specific properties (DynamicConfiguration)</b>
How can we set adapter specific properties in our own adapter code? Where are the Java docs of the API? Is this somewhere documented?
If you would have more information (or pointers), please post it as a response to this message.
Kind regards, Guy Crets
<b>Code snippet:</b>
XIMessageFactoryImpl mf = new XIMessageFactoryImpl();
Message msg = mf.createMessageRecord(fromParty, toParty, fromService, toService, action, actionNS);
msg.setDeliverySemantics(DeliverySemantics.ExactlyOnce);
// In case of XML documents it is not necessary to set the contentType or encoding
// But: take care that the encoding definiton in the XML document corresponds to the encoding used
if (msgText.indexOf("<?xml") != -1)
// Check whether the payload is a XML document. If not, treat it as binary to demonstrate how
// binary main documents work
// First create a XML Payload
XMLPayload xp = null;
xp = msg.createXMLPayload();
xp.setText(msgText);
xp.setName("MainDocument");
xp.setDescription("XI AF Sample Adapter Input: XML document as MainDocument");
msg.setDocument(xp);
// In case of binary documents use the Payload super class methods to fill the XMLPayload object
else
// Check whether the payload is a XML document. If not, treat it as binary to demonstrate how
// binary main documents work
// First create a XML Payload
XMLPayload xp = null;
xp = msg.createXMLPayload();
//xp.setContentType("application/octet-stream");
xp.setContentType("application/xml");
xp.setName("MainDocument");
xp.setDescription("XI AF Sample Adapter Input: Binary as MainDocument");
xp.setContent(msgData);
// Finally set the main document in the message
msg.setDocument(xp);
TRACE.debugT(SIGNATURE, XIAdapterCategories.CONNECT_AF, "Message object created and filled.");
ModuleData md = new ModuleData();
md.setPrincipalData(msg);

Hello Moorthy,
I know this part of the documentation.
So I set the indicator within the communication channel.
Now, I have to fill the dynamic configuration during my mapping. My code looks like following:
DynamicConfigurationKey keyURL = DynamicConfigurationKey.create("http://sap.com/xi/XI/System/HTTP", <b>XXXXX</b>);
// access dynamic configuration
DynamicConfiguration conf = (DynamicConfiguration) param.get (StreamTransformationConstants.DYNAMIC_CONFIGURATION);
// set value
conf.put(keyURL, url);
So what has to be filled instead of XXXXX ?
Regards,
Marc

ABAP XSL mapping - Binary data of attached file

I have a webservice which is converting attachment and putting it into XSLT Node. when I mapped this node to Attachment payload of my partner (using ABAP xsl mapping), I got an error.
I was able to send the same file via SOAP UI...
On further investigation of the http log files, I noticed that Binary data for both streams looked same, but when I did a word count, I noticed that SOAP UI was a single line file while my PI data was more than 400 lines.. so I coded a fn:transfer of this data to convert end of line character to empty value. it did seem to work...
My question, is this approach correct? or is there any way to ensure binary data stream in XML node does not contain those additional characters?

can you provide input xml

How to receive the images / binary data t ype

How to receive the images / binary data type in webdynpro....
i have a website that let's the user send email, the email attachment and message are stored in both in images data type....
q1) can i stored the message into binary data type...but the message is very long.....
q2) if i have a textbox ...i surely will need to display the message in string ,right ?
[......... msg here ........]
what is the codes to receive the images / binary data type in webdynpro....

As in your previous post if you are storing them as BLOB object.. am sure you are able to get a byte stream or byte array(bytes[]) out of it.
There should be some way to identify if its a image or a message BLOB. If its a image , convert into bytes and use
WDWebResource.getWebResource(bytes,resource type).getAbsoluteURL()
to obtain the url.. assign this image UI element..
In case its the message , use bytes.toString to get the message ..

Reading the binary data from a http request received via socket connection.

1. I require to extract the binary data out of a http multipart request,
2. I have a server socket opened up, which can receive connections over tcp( and therefore http.)
3. I will require to read the stream, find out the "request boundary identifier", and then extract the different "request body parts".
4. From there i need to read all of the binary content and put it in a file.
5. I did some implementation to his effect. but i see that the file that i had uploaded initially if its not a text file, gets corrupted.
can you please let me know why is that happening, and a probable solution approach.
please find below the class (with a main method) I have been using to expose a server socket.

Here is a sample html file which can be used to send multipart requests to the java service.
<html>
     <body>
          <form action="http://localhost:9999" enctype="multipart/form-data" method="POST">
               Enter name :<br/>
               <input type="text" name="yourName"/>
               Enter file :<br/>
               <input type="file" name="sentFile"/>
               <br/>
               <input type="submit" value="Submit"/>
          </form>
     </body>
</html>
*Both the form elements are mandatory*
*I hope my requirement is clear. Any help regarding this will be highly appreciated.*
Regards.

can you please let me know why is that happening,Because you are using a Reader (which translates bytes to chars according to the charset encoding specified).
and a probable solution approach. Use a BufferedInputStream.
