DETAIL_DATASTORE for binary data

can i put binary data like PDF,word doc in DETAIL_DATASTORE?

You should as this question in the Oracle Text forum, where you will get a more expert, quicker answer.

Is there an object like StringBuffer, but for binary data?

I like the performance of StringBuffer, it's very fast when I use the indexOf() and lastIndexOf() methods.
Is there an equivalent buffer object for binary data so that I can quickly search for byte sequences fast instead of looping through it?
Thanks.

I like the performance of StringBuffer, it's very fast when I use the indexOf() and lastIndexOf() methods.You mean fast as in O(n)?

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

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

Best Datatype for Binary Data

Hi,
We storing a Binary Data say "ù?" in oracle as String Datatype.
I have formed the query in my application to insert a record which has above string as one of the String field value.
The insertion was success but when the above string is not stored as it is but it is stored as "¿ù?" which is not a correct data.
Is this problem is because I'm using string for storing binary data?
Also please let me know what could be the best data type to store the binary data (like above data) in oracle.

Justin,
With the help of your query I identified how the bytes are stored in the memory.
I'm having VARCHAR2 datatype of size 14 in oracle when ever i store my binary data it is storing as
127,0,0,0,0,0,0,0....for 14 bytes -> So the binary equivalent is 011111111,00000000,00000000,...... And i'm ok with it.
But the problem is whenever a byte is holding the binary equivalent of 128 it is storing in the oracle as 191
eq:
Bits: 10000000 => equivalent to 128 in decimal and it is what i want to get when i query it using select, but what i'm getting in sql query is "191".
Really I'm not able to understand the relationship beween 128 and 191 binary values.
I got the above detail using the DUMP sql function.

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

Plugin for binary data: channels with coefficient : y = a3*x^3 + a2*x^2 + a1*x +a0

Hello,
I am bulding a plugin for extracting data from a binary file.
My problem is that the scaling of the values is not defiened by a linear equation (y = a1*x + a0 where conversion is easy with Factor and Offset properties of Channel), but by a cubic equation (y = a3*x^3 + a2*x^2 + a1*x +a0) with 4 coefficients. For the moment, I performed the operation in a loop over all the values of the channel... this takes a lot of time to convert all the values!!! Is there a more efficient way for multiplying array in VBA or channels in DIADem (for Plugins!!!)...?

Hi Ollac,
There is no way to efficiently apply polynomial scaling in a DataPlugin. You could create each of the polynomial component terms with an eMultiplyProcessor type ProcessedChannel in the DataPlugin, but we can't add them together with another ProcessedChannel because you can't add a ProcessedChannel to another ProcessedChannel. If the manual cell-by-cell scaling that you've already tried is too woefully slow, then I'd suggest exposing the raw data values to channels in the Data Portal and adding the "a0", "a1", "a2", "a3" polynomial coefficients as channel properties. Once the raw data is in DIAdem, you can use the ChnCalculate() or the older and faster FormulaCalc() command to apply the polynomial scaling in-place based on the coefficients in the channel properties. You might want the Data Plugin to add the "_Raw" suffix to the channel names and have the scaling VBScript remove the "_Raw" suffix or replace it with a "_Scaled" suffix so you don't accidentally apply the polynomial scaling twice.
Ask if you have questions about this,

Use httpchannel/httpservice combination for binary data

I have a blazeds proxy configuration set up with my flex application to communicate with a RESTful webservice.
This webservice is practically an interface to a content management system which has all types of content text and binary(audio,video,images etc) protected by HTTP basic authentication. I had no reason to use Blazeds except for its proxy capabilities to enable HTTP Authentication headers to be sent from the application to the webserver which dont work when sent directly to the server as mentioned.See related post below -
http://tech.groups.yahoo.com/group/flexcoders/message/136576
I send the requests through HTTPService from flex through a configured destination and it works well for all data formats supported by HTTPservice. Unfortunately HTTPService does not support binary resultformat for images,audio and video. I am aware that i should use a streaming server for audio and video data but for images I would like to go through the blazeds proxy to the webserver. Loader is the only class which is recommended to be used with images but i am not sure of how to use it with blazeds.
Is it possible in anyway to achieve what I am trying to?
Thanks,
Peeyush

Try this...
var b:ByteArray = _dataLoaderHTTPService.lastResult as
ByteArray;
b.position = 0;
trace(b.readObject());

Ideal column type for Binary Data ??

Hi there,
I must store binary data of fixed length (e.g. IP address of 4/16 bytes) into a table and manipulate that table over C++ / OCI.
The database server is running on either SUN/SPARC or LINUX/i86. The clients are running on a broad range of systems (NT/i86, LINUX/x86, SUN/SPARC, ..).
I am worried about the OCI layer modifying char/varchar values while transmission ...
Whats the best approach ??
Use CHAR/VARCHAR or use the variable length RAW even for fixed length binary data ??
Any help would be greatly appreciated,
Tobias
null

I guess RAW is the best approach

Using custom document protocal in B2B for Binary data transfer

Hello All,
Below are the steps that I am performaing in my project
1) I am enquing the message using B2b adapter to JMS queue on SOA server
2) I have selected opaque and binary fomat while configuring the JMS adapter
3) Before invoking b2b adapter to push the message, trying to set below proeprties in bpel
<bpelx:toProperty name="b2b.fromTradingPartnerId"
variable="varFromParty"/>
<bpelx:toProperty name="b2b.toTradingPartnerId" variable="varToParty"/>
<bpelx:toProperty name="b2b.documentTypeName"
variable="varDocTypeName"/>
<bpelx:toProperty name="b2b.documentProtocolVersion"
variable="varDocTypeRevision"/>
<bpelx:toProperty name="b2b.documentProtocolName"
variable="varEventName"/>
<bpelx:toProperty name="b2b.documentDefinitionName"

variable="varMsgType"/>
<bpelx:toProperty name="jca.jms.JMSProperty.DOCPROT_NAME"
variable="varEventName"/>
on B2b console
1) I have configured JMS listenign channel, file deliver channels properly
2) I have defined docuemnt definition under custom document protocal without xsd
custom->1.0->Binary->Binary_def
3) created agrement and selected file as deleivery channel
when testing this case
- bpel- B2b adapter successfully pushing message into jms queue on soa server
- b2b jms listening channel is able to pickup the message from jms-queue but encountering with the document protocal definition error
- if I check reports section - sender and reciever are showing as same partner name where as in wired message all the properties(to_party, from_party etc..) are getting populated with the values that we sent from bpel
I am not able to figure out the issue so please let us know what extra parameteres that I need to send from bpel to come out of this issue. PLease treat this as imp since i have deliverable.
Thanks,
Anjana

Hi Anuj,
Thanks for the quick response. This option fixed the issue. thanks for your suggestion.
I tried this option earlier when I was doing some R&D, at that time message iteself was not picked up by B2b listening channel from jms queue so I have unchecked and didn't try this option again.

Anjana

How to read a file with both text and binary data?

For text data I use a BufferedReader,
for binary data I use a DataInputStream.
Since readLine is deprecated in DataInputStream, how can I read in a proper way a file that contains some lines of text followed by some binary data.
Is there a way to do this without writing a new 'readLine' for DataInputStream (that has to take into account the different newlines for Unix en other OS's)?

sorry about that ^
NEW STRING str
WHILE there is stuff in the file DO
    getByte()
    IF reading a string THEN
        WHILE byte is not a return character DO
            convert the byte to character/string
            append char to str
        WEND
    ELSE IF reading raw data THEN
        parse raw data
        do stuff with it
    END IF
WEND

Convert Binary Data into Pdf & send it as attachment in a mail from R/3

Hi,
Scenario:
The interactive form saved in WebDynpro Application is sent to R/3 in binary format. It has to be converted into pdf and sent it as an attachment in mail to the respective person in workflow.
Kindly help on these issues :
1. How to receive the binary data in R/3 sent by the WebDynpro Application ?
To my knowledge we can receive the binary in XSTRING data type. Plz correct me if am wrong.
2. How do i convert the received binary data into pdf ?
Thanks,
Bharath Kaushik Krishnan

HI Bharath,
I think You can reuse teh XString for binary data.there are certain function modules in R/3 for creating pdf/for sending it as pdf attatchment.please search in abap forums you will find more information

Binary data import with UTC

Hi!
I have a ldif file, which contains binary data (jpeg-photo) and I want to import this data (output of an X.500) into a connector view.
I implemented a conversion routine, which converts all base64 values to utf-8, but for binary data, it doesn't work.
any idea, how I can convert the inputdata, so that the UTC can import it to the connector view?
thx and greetings
michi

not so.
extended ascii "characters" from the iso_8859_1 set need to be converted to to UTF-8 to be written to CV in LDAP directory.
agreed that binary should be in base64 in that case each "character" has to be UTF-8

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 :

Best practice for putting binary data on the NMR

Hi,
We're creating a component that will consume messages off the NMR, encode them, and subsequently put them back on the NMR. What's the best practice for sending binary data over the NMR?
1. setContent()?
2. addAttachment()?
3. setProperty()?
If NormailzedMessage.setContent() is the desired approach, then how can you accomplish that?
Thanks,
Bruce

setContent() is used only for XML messages. The recommended way to accommodate binary data is to use addAttachment().
