Publish binary data from OSB JEJB PS to a mq queue

Hi All,
I have a JEJB proxy service which has 3 arguments, : 2 strings and one is a byte array.
I want the third argument: i.e th byte array to be passed on as it is to a mqueue.
Now in my JEJB proxy service, I am only logging all the 3 parameters and replacing the body node contents with this 3rd parameter.
The message goes into the queue but as an xml like :
<soap:Body xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"> <con:java-content ref="jcid:-3a54550:12ed83aa9da:-7f5a" xmlns:con="http://www.bea.com/wli/sb/context" xmlns:ns="http://www.openuri.org/"/> </soap:Body>
But I ideally I want the binary data referred by that content to be passed to the mq queue.
Can anyone please help in this regard.
Thanks in advance

Encoding problem while reading binary data from MQ-series

Dear all,
we are running on 7.0 and we have an encoding problem while reading binary data from MQ-series. Because we are getting flat strings from queue we use module "Plain2ML" (MessageTransformBean) for wrapping xml-elements around the incoming data.
The MQ-Series-Server is using CCSID 850, which we configured in connection parameters in communication channel (both parameters for Queuemanager CCSID and also CCSID of target).If there are special characters in the message (which HEX-values differ from codepage to codepage) we get errors in our adapter while executing, please see stack-trace for further analysis below.
It seems to us that
1. method ByteToCharUTF8.convert() expects UTF-8 in binary data
2. Both CCSID parameters are not used anyway in JMS-adapter
How can we solve this problem without changing anything on MQ-site?
Here is the stack-trace:

Any ideas?
Kind regards, Stefan

Hi Stefan,
for the first MTB now we are using only one parameter: Transform.ContentType = text/plain;charset="ISO-8859-1"
The second MTB, which does the XML-Wrapping, is configured like this:
Transform.Class = com.sap.aii.messaging.adapter.Conversion
Transform.ContentType = application/xml
xml.conversionType = SimplePlain2XML
xml.fieldNames = value
xml.fieldSeparator = §%zulu§%
xml.processFieldNames = fromConfiguration
xml.structureTitle = payload
Both CCSID configuration parameters from the "Source"-Tab we've set to 850.
Now, we don't get an error anymore - sun.io.malformedInputException - , but, unfortunately, now special character conversion succeeded (we need an "ß" and we get an ISO-HEX-E1 -> á). E1 is (different from ISO) an "ß" in 850.
Any ideas?

Sending attachments/binary data from flex to Restful APIs

Hi,
We have a requirement of sending the files (or binary data) from flex GUI to Restful services(backend APIs). We are using flex HTTPService component to invoke the rest apis. The Rest APIs are designed to accept the multipart/mixed data which can support the binary data as well.
Can any one help us understand, how can we send the multipart/mixed OR multipart/form-data from flex to backend using the HTTPService. Or is there a better way to send the mixed data from Flex GU to Restful APIs.
Request you to please respond to this at the earliest as this is very urgent.
Thanks and Regards,

Has anyone worked on this issue?? i wanted a quick response as we are in the middle of the development and this is a r

Reading binary data from a URL

Below are 2 snippets of code that read data from a binary file. A small sample of the output is shown at the bottom of each code fragment. The first one uses the URL class to read a remote file. The ouput for this fragment is incorrect in some cases. The second uses a stream reader to read a local file (the output is correct in this case). Both fragments read the same file.
As you can notice, some of the bytes read are the same in both cases. Some others are not.
I hope you can suggest how I can fix my URL version.
Thanks for your help.
Miguel
Program A: Reads a remote file with URL
URL url = new URL("http:localhost//myfile.awg");
URLConnection connection = url.openConnection();
BufferedReader bin = new BufferedReader(new InputStreamReader(connection.getInputStream()));
while(true) {
System.out.println(Integer.toHexString(bin.read()));
7d 3 0 0
22 30 3 3e
fd b9 2a 0
b2 2 0 1
Program B: Rads a local file
DataInputStream din = new DataInputStream(new BufferedInputStream
(new FileInputStream("c:\\inetpub\\wwwroot\\myfile.awg")));
while(true) {
System.out.println(Integer.toHexString(din.read()));
8e 3 0 0
99 30 3 3e
81 b9 2a 0
b2 2 0 1

What can I use instead?
Thanks,

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.

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.

Why is performance so slow reading binary data from a SQL Azure DB with EF6.x

I'm running a WPF client that hits a SQL Azure DB using EF 6.x. For the most part, everything seems to be working fine. The one exception is when I try to read a large binary column.
I am storing files in the DB as a binary column. When I test using the local DB, everything sings. When I switch to the Azure DB, I get timeouts when I try to read the file contents. I have no problem saving the binary data to the DB, just
reading it.
I don't know how to troubleshoot this. I looked at the Query Performance page in the Azure portal, but it doesn't time stamp anything in there and you can't clear it, so I can't correlate what's running with the queries that show up there.
I tried to start SQL profiler against the DB, but was denied because I'm not a member of the sysadmin fixed server role.
If I query for the data directly, it comes back quickly. So this seems to be an Azure via EF issue.
Any help is appreciated.
http://digitalcamel.blogspot.com/

Hi Digital Camel,
Since I don't know what your scenario is, I won't argue too much about not storing binaries in your SQL DB, but still: don't store binaries in your SQL DB :). The main reason is simple: first and foremost, in both the current and future pricing tier your
levels are defines on the size of the DB. Basically, you pay way more by storing your binaries on your SQL layer rathern than storing them elsewhere, such as Azure Storage. Second, the protocol your binaries would be downloaded over the wire is prone to network
connectivity issues: you could use HTTP(S) or FTP instead, if you'd use Azure Storage. Last but not least, when you download the binary from your DB, you keep a connection open which in the end is a connection other users might have used to query data instead.
However, in regard to your question, how did you "query for the data directly"? Did you try to query the data using SSMS with the Client Statistics option on? This could tell you if the problem is network, server or client related.
Hope this helps!

Sending binary data from JSP (1.1)

Hi all:
I am using Tomcat 3.2.1 and Apache under Linux Mandrake OS.
I have a JSP (1.1) sending binary data (GIF, PDF, DOC ..) using response.getOutputStream().write(data)
method.
The problem is the precompiler automatically creates the JspWriter and puts some out.write("\r\n") lines
before I use getOutputStream method. The JVM throws an IllegalStateException because I am using both

Must I change my code to forwarding to a servlet that make this work or is there a simple solution to
avoid this?
Thanks in advance.

Hi Shreeharsha
Please refer to below docs for sending data from JSP page to RFC. In which you need to use sap connectors for connecting to SAP backend system.

How to return binary data from a servlet?

This is my problem:
I have a table (generated from a database), and I would like the user to be able to select a one of the items in the table. When the user clicks the link I would like to transfer a piece of binary data stored in my database.
I am quite new to Creator and web apps, so I don't really know the best solution to implement this. I have one requirement: I must log the file transfer in the database (the web-servers log is not good enough...)
Any help would really be appreciated...

Hi Trond,
Please have a look at the following thread.
http://swforum.sun.com/jive/thread.jspa?forumID=123&threadID=46410
It discusses how to display an image stored in the database table. This discussion may provide you with useful information.
Hope this helps

Working with Binary data from the Gpib Read Function

I m using the gpib read command to recieve data from a gpib instrument. I already know the form of the binary data being sent back. I have programmed it in matlab before. I am haveing trouble parseing out the binary data I recieve. the basic form of the data is
#I immediately followed by 401 64 bit ieee floating point numbers. When I programmed this in matlab the code I used was of the form:
[a,count,msg]=fread(g2,2,'int8');
[a,count,msg]=fread(g2,401,'float64');
for those that don't know matlab code the command reads data from the instrument pointed to by the g2 handle. the number after the g2 above speicifies the number of values to read. And the last part the string in qoute specifies the way the binary data
is to be interepeted. the output arguments a count and msg are
a-your data
count-number of items succesfully read in
msg-error message
In the above two lines I use the variable a twice to capture the data. The first time a is set equal to '#I' everything inside the qoutes. The second time a is set equal to the actual data, in this case 401 64bit floating point numbers. I m convince that the flatten to string and unflatten from string function are the set meant to accomplish this task. But I haven't been able to find a good example of how to use these functions. Especially with an array.
Can some one please help me?
Thanks

I'm pretty sure what you're describing is a simple typecast in LabVIEW. You will want to strip off the #I first, using string manipulation functions. Then, you can wire the string into a "typecast" VI, and wire a double precision float constant to the top connector of the typecast (this tells the VI that you expect a 64 bit float output) and then you can read your resulting array of double precision floats on the output of the typecast. The typecast VI is found in All Functions >> Advanced >> Data Manipulation.
I've attached an example in LabVIEW 7.0 and also 7.1 format.

Extract binary data from resource_view (/Resrouce/Contents/binary)

Hi,
I've uploaded an image (png) as a resource using ftp. Now I'd like to extract the contents of the png file using the resource_view.
In my test the uploaded file was placed in /public/tmp and was named test.png.
Using the following query I tried to get the data:
SELECT extract(res,'/Resource/Contents/binary') AS content, extractValue(res,'/Resource/ContentType') AS ContentType
FROM resource_view
WHERE equals_path(res,'/public/tmp/test.png') = 1 The output was something like:
<binary xmlns="http://xmlns.oracle.com/xdb/XDBResource.xsd">89504E470D0A1A0A0000000D494844520000023E00000181080300000051984BA3000003
00504C5445000000BF000000BF00BFBF000000BFBF00BF00BFBFC0C0C0C0DCC0A4C8F0111111222222444444555555777777AAAAAADDDDDDEEEEEE00001100002200
00440000550000770000880000AA0000BB0000DD0000EE00110000220000440000550000770000880000AA0000DD0000EE0011000022000044000055000077000088...</binary>
image/pngThis looks a lot like ASCII :-) Following the XSD the binary data is hexBinary encoded.
My question is how to get the binary representation?
(oh, I'm running 11g on 64bits Windows)
Edited by: Tijink on Feb 2, 2009 3:20 AM

First create a function to convert the hexvalues in the string to a blob:
create or replace function myclob2blob( p_clob in clob )
return blob
is
t_blob blob;
begin
dbms_lob.createtemporary( t_blob, true );
for i in 0 .. trunc( length( p_clob ) / 4000 )
loop
    dbms_lob.append( t_blob, to_blob( hextoraw( to_char( substr( p_clob, i * 4000 + 1, 4000 ) ) ) ) );
end loop;
return t_blob;
end;
/And then query the binary data using this function
select extractvalue( rv.res, '/Resource/DisplayName' ) displayname
     , extractvalue( rv.res, '/Resource/ContentType' ) ContentType
     , myclob2blob( bin ) bin
from resource_view rv
   , xmltable( '/' passing extract( rv.res, '/Resource/Contents/binary' )
                columns bin clob path '/*'
where equals_path( rv.res, ''/public/tmp/test.png' ) = 1 Anton

Publishing Serial data from CFP to several clients

Does anyone know how I can share information I am getting off of one of
the RS 232 ports on the CFP 2020 with several clients. Since my
application is embedded in order to communicate with the serial ports I
can only seem to access the embedded VI one client at a time.
How can I share this info?

JAIME
Datasocket is very simple way to share information between several LabView applications, running on PCs or (c)FP controllers.
You can start from http://www.ni.com/datasocket/
Second way is to run on the cFP 2020 a stand alone .exe file which will read the data from RS232 device, and publish it to many LV clients , see this link:
http://sine.ni.com/apps/we/niepd_web_display.display_epd4?p_guid=B45EACE3E64D56A4E034080020E74861
Third, you can also use TCP/IP read / write commands to build your communication with any LV applications.
Surely, all the PCs and controllers should be connected on a same subnet.

How to extract binary data from a File?

Hello there!
Hope I'm right here.
I have a slight problem with a file containing text- and binary-data. At the beginning of the file is only some text followed by some html-code and at the end is some binary stuff like a pdf oder an image (jpg/gif).
My problem is now how to split these parts and save them in the suitable format. The text and the html are no problem, but I don't know how to extract the binary data. I tried it out with an Inputstream, but I don't know how to find the exact position where the binary data begins.
Anyone have an idea how I can solve this?
Thanks in advance and sorry for my bad english.

I don't believe a bullet-proof solution exists.
If you know where the HTML ends, you may skip whitespace and then assume the rest is binary data. Or, if you know the first bytes of the binary data, you may locate those. With either of these solutions, though, you risk coming across a file where it doesn't work as expected, for example if the first byte of the binary data happens to match a whitespace character.

Problem in showing binary data from database

Hi,
I store some image files in my Oracle database and I want to show them in JSP pages. I constructed a jsp page which returns the image, foto.jsp looks like this:
<jsp:useBean id="photo" class="BizDel.Foto" scope="session" />
<%
int iNumPhoto;
Connection conn=null;
try{
DriverManager.registerDriver(new OracleDriver());
conn=DriverManager.getConnection("jdbc:oracle:thin:@server:1521:orcl", "username", "password");
conn.setAutoCommit (false);
byte[] imgData=Foto.getPhoto(conn);
response.setContentType("image/gif");
ServletOutputStream o=response.getOutputStream();
o.write(imgData);
o.flush();
o.close();
catch(Exception e)
e.printStackTrace();
throw e;
finally
conn.close();
%>
Foto.getPhoto() returns the image file as a binary array.
In the jsp page that I want to display the image, I wrote
<img src=foto.jsp/>
I see that the image processed, but nothing is displayed in the page. When I wrote the foto.jsp directly in the address bar, the image is retrieved properly and the page tries to process it as a file(tries to find a plugin for displaying the image file, that I dont want to.).
Can anyone help?

Andi,
Thanks for your suggestion.
I tried your way. Here is the servlet code:
public void doGet(HttpServletRequest request,
HttpServletResponse response) throws ServletException, IOException {
int iNumPhoto;
Connection conn=null;
if(request.getParameter("imgID")!=null){
iNumPhoto=Integer.parseInt(request.getParameter("imgID"));
try{
DriverManager.registerDriver(new OracleDriver());
conn=DriverManager.getConnection("jdbc:oracle:thin:@server:1521:orcl", "username", "password");
conn.setAutoCommit (false);
//retrieves the photo from database, works well...
byte[] imgData=Foto.getPhoto(conn);
response.setContentType("image/gif");
OutputStream o=response.getOutputStream();
o.write(imgData);
o.flush();
o.close();
catch(Exception e)
e.printStackTrace();
throw e;
finally
try{conn.close();}catch(Exception e){}
Again, there is no exception but the page does not show the image. When I directly write the servlet in the address bar, this time nothing happens, I cannot see the image.
Any suggestions...?

Display binary data from DB in browser using JSP

Hello everyone:
I uploaded some files from browser and stored the files in bytes in the database, but later on I could not display the files in browser without saving them to a local storage first. Is there any way I can send the bytes to the browser in the right format using JSP?
I tried the following:
response.setContentType(..)
response.getOutputStream().write(bytes);
I can see that the browser can get the right contentType, but with a bunch of weird symbols in the browser. Please help.
Thank you very much for your time.
Heather

I actually had to do this a few months ago. There are ways to perform this kind display using various distributed object (i.e., using MS Word OLE objects to "interpret" the byte for you, etc.). But this soon got extremely difficult to manage (and I actually had to use Perl/CGI for the majority of it).
The solution I went with was to implement a "cache" directory on the web server. Basically, the JSP/Servlet can simply check the cache and if file not there, create it from the database. Then send a redirect back to the browser to this newly-created file. The browser will then appropriately open the document. I tested this with both Netscape and IE browsers and common MIME types such as text files, MS Office docs, zip files, PDFs, RTFs.
Not ideal, but unfortunately the best I came up with.
