EJB : Binary data download

Please tell how to download large binary data (100-200Mb) from Db through EJB.

Where is the EJB executing ?.
Are you mentioning about the EJB container of JServer ?.
I do not see anything different compared to the procedure used to retreive data from the database using any Java client. You need to use JDBC and retreive the data from the columns which store the data

Download file problem for binary data?

Dear All,
I have wrote a jsp file to do download page. I have used a piece of code from the JDC to this. This code will prompt the download dialog box each time user clicks the download button. The code itself will set the content type for different application. The code is like below:
try
java.io.File fileobj = new java.io.File(strFolder + strFile);
response.setContentType(application.getMimeType(fileobj.getName()));
response.setHeader("Content-Disposition","attachment; filename=\""
+ strFile + "\"");
java.io.FileInputStream in = new java.io.FileInputStream(fileobj);
int ch;
while ((ch = in.read()) != -1) {
out.write(ch);
out.flush();
in.close();
} catch(Exception e)
The code can download and handle text file correctly when it is openned in the text editor or inside the IE. But when a PDF file or Image is downloaded and openned in the PDF viewer or image viewer, it is corrupted and cannot be viewed. What is the problem? Any ideas?
So, I wonder this code can handle binary data or not. It is seen like there is no different code to handle text and binary data in Java/Jsp.
Thank you very much!
Best Regards,
Rockyu Lee


Add following lines to .tld file (custom tag definition)

Add following line to JSP files.
In JSP, keep one line of source. Make sure that there are no space and additional line feeds at the any where

You may have to change 'inline' to 'attachment' if you do not want IE to inline the document.
That's all!!.. Hope this helps...!

Download Binary Data File over Serial Port

I need help setting up a .vi that I can use to download a binary data file from a dos-based system. I will send the system a command, say ascii "DOWNLOAD", and then the remote system will send me a binary data file that will be approx. 600MB. I won't be doing any display/manipulation using labview, I will just need to have the option available in LV to recieve the file.
Any examples would help a programmer that is new to LV and is getting a little desperate.

A VISA Read doesn't care whether the data it's getting is binary or ASCII. Where you might have problems is detecting that file transfer is complete. If you have enable termination character set to True in the VISA Configure Serial Port, the read will stop as soon as the termination character is detected. The default termination character is 0xA or a linefeed. You probably don't want to use this. If the file is terminated with a character or string of characters that you now will be unique, you can use this. If there is no unique termination character at the end of the file, the next best thing is to know the file size exactly and set the byte count of VISA Read to that number. Based on file size and baud rate, you would also need to adjust the VISA timeout value. Another way to do this is to transfer the data in pieces and write to a file as soon as the data is received. The reading of data would then be terminated when there are no more bytes available at the serial port. I've attached a LabVIEW 7.0 program that should give an idea of the last approach.

Airport downloading binary data instead of loading web page?

I've been having the usual problems with dropped connections for the past month since I set up my new dsl service. It didn't bother me too much since all I had to do was unplug my airport and plug it back in. This morning it happened again and I decided to go ahead and update the firmware to 5.7.
Whenever I tried to open a web page, I would get a little popup box that stated I was trying to download binary data. It gives me the option of opening in Textedit, etc. I'd try a different web page and the same thing happened. I've tried this on multiple computers and multiple browsers with the same result. I then downgraded to 5.5.1: same result. Tried soft and hard factory resets. No help. It's not the modem, since I am connected to it via ethernet right now with no problems. I can't believe I am the only one with this problem but I've searched all over and cannot find a fix for this. Any suggestions (in english please, I'm not completely computer-literate)?

Where is the binary data of this icon stored and retrieved from Application server?

Hello guys,
Today I observed one phenomenon and could not explain it per my knowledge.
I have one url which points to an icon in application server:
https://<host name>:44301/sap/public/bc/ur/nw5/themes/sap_corbu/common/libs/Icon/SuccessMessage.gif
I could successfully open it via chrome:
and after that I could see an entry in ICM server cache. Everything works perfectly.
Then I tried to check this icon in mime browser in SE80. To my surprise, the folder /sap/public/bc/ur/nw5/themes is empty.
However, the ICM cache shows that there is a subfolder called "sap_corbu" under "themes" folder. But why I cannot find it in mime browser?
Then I write a report to retrieve the binary data of icon via CL_HTTP_CLIENT, and clear the ICM buffer via tcode SMICM.
I expect this time some database table will be queried to load the content of the icon, since now the buffer is not available.
To my surprise again, in SAT no database table is involved.
So now I am confused: since I have already cleared the ICM server cache, where does the icon binary data come from when I run the report to access the icon?
Best regards,
Jerry

Hello guys,
one colleague today told me that there is a zip file "ur_mimes_nw7.zip" in MIME repository /PUBLIC/BC/UR/ur_mines_nw7.zip. I download it locally and unzip it and indeed find many theme folders including sap_corbu folder and its resource files. So I guess there must be some logic done in web application server which will unzip this archive file and put each theme folder to the corresponding folders in application server. I would assume those logic are done outside ABAP stack side, this is the reason I cannot find any hint of them in ABAP backend via tcode SAT even I clear both client and server side cache.
Best regards,
Jerry

SAP DMS: Read document binary data stored in a 3rd party repository

Hi,
I'm totally new regarding SAP DMS and I'm a bit confused about what can or can't do, so maybe the question will be quite generic and unclear.
The scenario in my company is that we have multiple repository servers where we store our documents. When a document is created or modified in one of these repositories a new record is also created/modified in SAP DMS, but this DMS entry only contains the basic metadata information and a URL link to the document, not the content. When the user is in SAP DMS, the only way to access the document content, is via the link that will open the browser outside of SAP GUI and access the repository data using the laptop credentials.
I would like to know if DMS provides some kind of interface to be able to access the document content from SAP. Now we only have this unidirectional interface from the repository that creates the record in DMS with the metadata but there is nothing to retrieve the content.
Our main purpose is that we want to download all the files linked to a user (we have a logic to determine if a DMS file is linked to a user). The content of these files may be stored in different content repositories. So I would like to read the binary data in SAP from the different repositories and then be able to download it.
Thank you in advance for your help.
- Marçal

Hi Sagar,
This FM can't work since there is nothing configured in SAP to access to the file content. The DMS record only has a URL pointing to it.
Actually what I want to know is what do I have to configure in SAP in order to be able to use a FM like the one you mentioned.

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?

Binary data problem with web services on JRockit but not Sun JDK

I have a problem with binary data in SOAP and JRockit
(jrrt-3.0.0-1.6.0-linux-x64.bin) . I have an set of web services based
on EJB 3.0 which return images as byte arrays inside a SOAP envelope
to be consumed by .NET 2 services. The host app server is Oracle
Application Server 10.3.1 on RHEL Linux update 4, on 64 bit Xeon 5500
series HP blade hardware.
While most images are fine most of the time, one particular image
gives this message when being consumed in the .NET client:
The '■' character, hexadecimal value 0x1F, cannot be included in a
name. Line 2, position 380038.
The MSDN suggests that this is usually caused by non-escaping of reserved XML characters like < but this isn't one of those.
The SOAP looks ok and for the life of me I can't see why this ought to
be a problem, especially since the problem doesn't arise running with
the SUN JDK 1.6_06 64 bit)
When making the same call from the OAS Enterprise Manager, I can make the same call with no problem (but the data is just rendered as character data in a browser) which maybe suggests some incompatibility with how JRockit is serializing the data ?
Any ideas, I would be very happy to hear - JRockit gives a 15% or so
speed boost to the website that these services power so obviously we
want to use it if possible.
Edited by: RichLiv on Nov 14, 2008 4:54 AM

Seems to be the case that using MTOM stops this problem with JRockit. Strange but apparently true (so far).

Binary Data Type in finder methods for CMP beans

How to write an equivalent ejb-ql query in ejb-jar.xml for a finder method accepting
a byte array as a parameter. The finder method is for a cmp-field mapped to a
database field with binary data type

Using CMP 2.x, your custom finder and select methods are implemented by the container based on the EJB QL query you provide in the ejb-jar.xml. In CMP 1.1, there was no portable way to express the semantics of the query, so most vendors had a vendor-specific syntax for describing the query.
See chapter 27 of the J2EE 1.4 Tutorial for some examples of using EJB QL :

Using a servlet to send binary data

There is a section of our intranet that need to hold documents that have to be available only for a certain group of users. Here's my approach (if you think of a better one, please tell me):
1-all the files are in a directory upper than WWWRoot so that nobody can directly download them
2-there is a servlet that first: authentificate the user with username-password; and then lists all available documents.
3-When one of these docs is clicked, I want my servlet to open the file using filesystem File object and then copy the content of the selected file in the http response body. What object and method should I use to do so? I dont know if I should use FileReader or something else. Dont forget it will not only has to work with text files, but also with binary data files like swf, powerpointpresentation and the like. So I fear that objects such as FileRead will mess special characters up and corrupt data.
What would you advice me? Use FileReader or another object? Or maybe a completly different approach for the problem? And if you want to give me some sample codes, it would be appreciated.
Thx for your help

There is something I dont understand.. its bizarre. Usually I dont understand why a script is not working, but now, I dont understand why a scritp is working..
Here are the codes that copy from a file to the servlet's ouput:
//basic response configurations
response.setContentType( mimeType );
ServletOutputStream out = response.getOutputStream();
//copy a file f to the servlet's output stream
File f = new File( path );
FileInputStream fis= new FileInputStream(f);
int available = fis.available();
byte[] b = new byte[available];
fis.read(b);
out.write( b );
out.flush();
They work fine. What I dont understand is that I tried them with a file of about 5 megs, and they still worked! I expected them to fail because the variable available is of the type int and then it implies that the maximum file size permitted by the algorithm should be 65536 bytes/1024=64 ko... isn't it????

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 using HTP package

Has anyone been successful in using the HTP package and its PUTRAW procedure to send binary data to a browser?
Example code shows basic idea:
create or replace
procedure test_raw as
output VARCHAR2(20);
begin
OWA_UTIL.MIME_HEADER('application/x-gzip', TRUE);
output := 'Hello World!';
HTP.PUTRAW(UTL_RAW.CAST_TO_RAW(output));
HTP.FLUSH;
end test_raw;
I receive an empty file when called from the browser.
What gives?

I found my answer. I should be using wpg_docload.download_file(BLOB) to "download" a the contents of a BLOB.

URGENT! Can response object contain text as well as binary data

hi all,
My test scneario is like this..
a) User is having a button "Download File" i will call this as download.jsp
b) After hitting the download button i will be sending the file to user by writting into the ServletOutputSream.
c) Whatever option user chooses (i.e. Save / Open / Cancel) I want to do some updations on the existing user screen.
Maybe presenting him the download status e.g. "File Downloaded"
The problems i am facing are
1. SInce i am using ServletOutputSream once i flush the stream i loose the control on response object.
2. After user's operation (i.e. Save / Open / Cancel) unless user again hits
something on UI my server has to look at him with dumb eyes. :(
3.The download operation that i am performing expects some attributes from the request ..
they are Object attributes and not string attribute so i cant user URL rewritting.
If anybody has encountered this type of problem in there projects please share the workaround you used.
Thanx a lot
--Bhupendra Mahajan

Here in order to send the file to Client i must use Stream ... and in prder to
update the status i.e. HTML i must use Printwritter.... That is the reason
i need both ... If you have some OutputStream available deep down somewhere you can use
both; it just takes a bit of discipline:OutputStream ros; // available from somewhere
// use the following stream for your binary output:
BufferedOutputStream bos= new BufferedOutputStream(ros);
// and use this one for your PrintWriter:
PrintWriter pw= new PrintWriter(bos);Everytime before you want to print some binary data, flush the pw, and everytime
before you want to print some text data, flush the bos.
kind regards,

Displaying image from binary data using java

hi there,
i have created a swing applet displays me a url, what the url returns me is the image in binary format, and i want to show the complete image using that binary data
so how do i do it.
some thing like this :
URL url = new URL("http://192.168.1.1:8086/file-storage/download/Zerg.jpg?version_id=35688");
JEditorPane jep = new JEditorPane();
jep.setPage(url);
output is in binary on my applet window.

Hey,
This displays an image from a url, you could check if your url is and image or not using URL.getFileName() and see if it ends in gif jpeg etc. and then display it this way.
hope it helps

The problem of using webservice to transfer binary data

I want to use webservice to realize downloading file , and then I think we can to transform the whole file to binary data ,and then use webservice to deliver these datas to client. but there is a promble. When the file size is a bit large , such as exceeding 1.5M , then client will receive error report. How to solve this promble. Another I think when server transforming the whole file to binary data , It should apply for much memory , as large as the file. I think this is not a good solution . Any one can give me some ideas ? How to realize download file using webservice(the server is oc4j)
