Blob to base64 encoded XML

Hi,
We have a table with two columns (Name varchar2, Picture Blob).
How do we get XML output containing rows from table, with Picture (blob column) being base64 encoded.
Note: I have tried using utl_encode.base64_encode, but getting error due to large size of Picture.
Thanks,
Yj

I am not sure what you finally want to accomplish (create a binary xml?), but to base64 encode a blob you could do it »stepwise«:
declare
   bl            blob;   /* your picture blob */
   bl_enc        blob; /* encoded blob */
   offset        integer            := 1;
   amt           integer            := 20000;
begin
   dbms_lob.createtemporary (bl_enc, false);
   while dbms_lob.substr (bl, amt, offset) is not null
   loop
      dbms_lob.append (bl_enc, utl_encode.base64_encode (dbms_lob.substr (bl, amt, offset)));
      offset := offset + amt;
   end loop;
   convert_to_xml(bl_enc);
   dbms_lob.freetemporary (bl_enc);
end;

Problem with base64 encoding an xml file with accented characters

Oracle 10.2.0.1.0 Enterprise Edition running under windows 2003 server
DB Characterset UTF-8
I have a routine which takes an xml file and base64 encodes it, and the base64encoded text is stored in a clob column of a table.
The xml file is stored in UTF-8 format.
The routine works correctly, except when there are accented characters.
I am using dbms_lob.loadclobfrom file to load the file.
DBMS_LOB.OPEN(src_clob, DBMS_LOB.LOB_READONLY);
 DBMS_LOB.LoadCLOBFromFile(
 DEST_LOB => dest_clob
 , SRC_BFILE => src_clob
 , AMOUNT => DBMS_LOB.GETLENGTH(src_clob)
 , DEST_OFFSET => dst_offset
 , SRC_OFFSET => src_offset
 , BFILE_CSID =>dbms_lob.default_csid
 , LANG_CONTEXT => lang_ctx
 , WARNING => warning
 DBMS_LOB.CLOSE(src_clob);base 64 encoded xml with accented character -- incorrect

Parsing a UTF-8 encoded XML Blob object

Hi,
I am having a really strange problem, I am fetching a database BLOB object containing the XMLs and then parsing the XMLs. The XMLs are having some UTF-8 Encoded characters and when I am reading the XML from the BLOB, these characters lose their encoding, I had tried doing several things, but there is no means I am able to retain their UTF encoding. The characters causing real problem are mainly double qoutes, inverted commas, and apostrophe. I am attaching the piece of code below and you can see certain things I had ended up doing. What else can I try, I am using JAXP parser but I dont think that changing the parser may help because, here I am storing the XML file as I get from the database and on the very first stage it gets corrupted and I have to retain the UTF encoding. I tried to get the encoding info from the xml and it tells me cp1252 encoding, where did this come into picture and I couldn't try it retaining back to UTF -8
Here in the temp.xml itself gets corrupted. I had spend some 3 days on this issue. Help needed!!!
ResultSet rs = null;
 Statement stmt = null;
 Connection connection = null;
 InputStream inputStream = null;
 long cifElementId = -1;
 //Blob xmlData = null;
 BLOB xmlData=null;
 String xmlText = null;
 RubricBean rubricBean = null;
 ArrayList arrayBean = new ArrayList();
 rs = stmt.executeQuery(strQuery);
 // Iterate till result set has data
 while (rs.next()) {
 rubricBean = new RubricBean();
 cifElementId = rs.getLong("CIF_ELEMENT_ID");
 // get xml data which is in Blob format
 xmlData = (oracle.sql.BLOB)rs.getBlob("XML");
 // Read Input stream from blob data
 inputStream =(InputStream)xmlData.getBinaryStream();
 // Reading the inputstream of data into an array of bytes.
 byte[] bytes = new byte[(int)xmlData.length()];
 inputStream.read(bytes);
 // Get the String object from byte array
 xmlText = new String(bytes);
 // xmlText=new String(szTemp.getBytes("UTF-8"));
 //xmlText = convertToUTF(xmlText);
 File file = new File("C:\\temp.xml");
 file.createNewFile();
 // Write to temp file
 java.io.BufferedWriter out = new java.io.BufferedWriter(new java.io.FileWriter(file));
 out.write(xmlText);
 out.close();

What the code you posted is doing:
// Read Input stream from blob data
inputStream =(InputStream)xmlData.getBinaryStream();Here you have a stream containing binary octets which encode some text in UTF-8.
// Reading the inputstream of data into an
into an array of bytes.
byte[] bytes = new byte[(int)xmlData.length()];
inputStream.read(bytes);Here you are reading between zero and xmlData.length() octets into a byte array. read(bytes[]) returns the number of bytes read, which may be less than the size of the array, and you don't check it.
xmlText = new String(bytes);Here you are creating a string with the data in the byte array, using the platform's default character encoding.
Since you mention cp1252, I'm guessing your platform is windows
// xmlText=new new String(szTemp.getBytes("UTF-8"));I don't know what szTemp is, but xmlText = new String(bytes, "UTF-8"); would create a string from the UTF-8 encoded characters; but you don't need to create a string here anyway.
//xmlText = convertToUTF(xmlText);
File file = new File("C:\\temp.xml");
file.createNewFile();
// Write to temp file
java.io.BufferedWriter out = new java.io.BufferedWriter(new java.io.FileWriter(file));This creates a Writer to write to the file using the platform's default character encoding, ie cp1252.
out.write(xmlText);This writes the string to out using cp1252.
So you have created a string treating UTF-8 as cp1252, then written that string to a file as cp1252, which is to be read as UTF-8. So it gets mis-decoded twice.
As the data is already UTF-8 encoded, and you want the output, just write the binary data to the output file without trying to convert it to a string and then back again:// not tested, as I don't have your Oracle classes
final InputStream inputStream = new BufferedInputStream((InputStream)xmlData.getBinaryStream());
final int length = xmlData.length();
final int BUFFER_SIZE = 1024; // these two can be
final byte[] buffer = new byte[BUFFER_SIZE]; // allocated outside the method
final OutputStream out = new BufferedOutputStream(new FileOutputStream(file));
for (int count = 0; count < length; ) {
 final int bytesRead = inputStream.read(buffer, 0, Math.min(BUFFER_SIZE, (length - count));
 out.write(buffer, 0, bytesRead);
 count += bytesRead;

Get canvas.toDataURL('image/jpeg') and convert base64 encoding to java.sql.Blob

Convert canvas.toDataURL('image/jpeg') to java.sql.Blob.
I am using oracle adf so I am able to action a backing bean from javascript and pass in parameters as a map. I pass in the canvas.toDataURL('image/jpeg') which I then try to decode in my bean. Using BASE64Decoder and the converting the bytearray to a file I can see the image is corrupted as I can't open the file thus converting the bytearray to blob is also a waste.
Has anyone any ideas on base64 encoding from canvas.toDataURL to file or Blob?

Use Case:
A jsf page that enables a user to take photos using the HTML5 canvas feature - interact with webcam -, take photos and upload to profile
1. I have created the jsf page with the javascript below; this pops up as a dialog and works okay and onclick an upload image, triggers the snapImage javascript function below and sends the imgURL parameter to the serverside managedbean

function snapImage(event){
 var canvas = AdfPage.PAGE.findComponent('canvas');
 AdfCustomEvent.queue(event.getSource(),"getCamImage",{imgURL:canvas.toDataURL('image/jpeg'),true);
 event.cancel();

public void getCamImage(ClientEvent ce){
String url=(String)ce.getAttributes().get("imgURL");
decodeBase64URLToBlob(url);
private BlobDomain decodeBaseB4URLToBlob(String url64){
 BASE64Decoder de=new BASE64Decoder();
 byte[] bytes=de.decode(url64);
 File file=new File("abc.jpg");
 InputStream in = new ByteArrayInputStream(bytes);
 BufferedImage bImageFromConvert = ImageIO.read(in);
 in.close();
 ImageIO.write(bImageFromConvert, "jpg", file);
 return createBlobDomainFromFile(file);
----problem---
Accessing the generated jpeg file shows the image is corrupted, probably missing bytes or encode/decoder issues.and the blob image after uploading to database is saved as a binary stream which ondownload doesnt render as an image or anything i know of.
Is there anyways of achieving the conversion without errors?

Is there a way in XML gateway to encode the payload automatically to base64 encoding so that it can accommodate the unicode
Is there any way to encode the order information from EBS tables to base64 format in the outbound SOAP request ? Is this supported . If yes, how.?
Does this involve customization. Is it possible to use encoder/decoder provided in sites such as XSL on top of XML : http://gandhimukul.tripod.com/xslt/base64-xslt.html
Basically, They are trying to use XML Gateway to send and receive messages to a Trading Partner via SOAP. The issues is
1. Outbound: The TP web service can only receive xml content that is encoded in base 64 binary format. How do we configure to encode content using base64
2. Inbound: They want to receive messages using the SOAP architecture into XML gateway.
Please let us know if you have any detailed configuration document for this purpose. Please advise and share relevant details.

Ajith

Hi Gurvinder,

Base64 encode attachments but not xml payload

Hi Everyone,
Using the soap adapter I know that I can use an adapter module and base64 encode everything. Is it possible to base64 encode the attachments but leave the soap/xml payload as text/xml?
Regards,
Joe

> Using the soap adapter I know that I can use an adapter module and base64 encode everything. Is it possible to base64 encode the attachments but leave the soap/xml payload as text/xml?
Do you want to have attachments of type base64, or do you want to have transfer-encoding base64? The latter is not possible with adapter modules.

Problem with My Base64 Encoding CLOB Routine.

I have written a program which reads an xml file into the database
and makes it Base64encoded.
This needs to work on 10g and above
If the read length specified in the code below is greater than the length of the xml_file, then I get the expected result(output).
However if the read length is less than the length of the file, then I get a lot of '==' in the file and as a result, incorrect encoding which means that the file will not be readable through the application.
I'm pretty sure I'm reading the blob lengths correctly, and the problem is somehow related to the base64 encoding.Any help appreciated

Base64 encoding encodes every 3 bytes of input data into 4 bytes of output data. It uses equal signs to indicate nodata and only at the end of the encoded sequence. Try chaning your v_read_length parameter to a multiple of 3 e.g. 960 or 1008 instead of the current 1000. I'm using multiples of 48 because the utl_encode.base64_encode function adds a linebreak for every 48 bytes of input data (64 bytes of output). If you use a value that's not divisible by 48 you will still get a legitimate encoding as long as it's divisible by 3, but you will get some lines longer than others when you append them together.

Base64 encode

Hi,
We have to provide a conversion of blobs to base64 in order to exchange data with
a 3th party. I wrote the following function which is used to format an xml-message.
Problem is the supplier reads this data with a .net decode of base64 complains it's invalid and it
sees some lines with more than 76 characters which seems to be not correct.
Any ideas what is wrong are greatly appreciated.

Yep, thats what I told you.
I have modified your code slightly.
This definitely produces your output.
Note that you were not using an oracle_directory for p_dir.
You should have said create or replace directory p_dir as 'your_location';
Instead you had p_dir varchar2(200) := 'your location';
The problem with the use of utl_file.put is you have to output a byte at a time. You were trying to output an entire clob, which is why it fell over.
Note: I also removed your exception handler as this just masks where the error is.
DECLARE
p_file varchar2(100):= 'test_img.png';
p_clob CLOB;
l_bfile BFILE;
l_step PLS_INTEGER := 19200;
dest_file varchar2(100):='test_image.html';

Base64 encoding in SOAP adapter

Hi,
Is it possible to transform outgoing messages to Base64 encoding format in XI using module processors and security encryption? I'm using receiver SOAP adapter (without SOAP header) and using PayloadZipBean module processor to zip the outgoing message. Also I need to add digital signature and base64 encryption to the zipped message. Please let me know how this can be achieved.
Thanks,
Dipankar

Flex XML Parsing fails on UTF-8 encoded XML.

Flex doesn't see reliable enough for handling XML.
This basic XML file causes an error in flex. Depending on the contents of the XML, it may or may not be invalid...and its not the characters. If I put in one type of UTF8 characters, the XML is OK, if I put in another type, its also OK. If I however put in both types...then the XML fails.
So in summary, good + good = bad.
Multiple browsers, multiple versions of Flash (latest, as well as a couple prior releases), multiple OS's.
XML headers indicate the content type correctly: Content-Type: text/xml;charset=utf-8
Any suggestions?
--Ben

I worked around the bad XML handling in Flex by Base64 encoding my data, then Base64 decoding it in Flex. I used com.dynamicflash.util.Base64 to do the decoding.
Its a shame though...wasting extra CPU and making the flash slower just because it can't handle XML reliably.

Convert a blob to base64

hi, someone who can help me how to convert a blob oracle in base64.encode,
and viceverse.
please some idea
tanks
alex

i saw a bit code about this convertions,
//one side
ResultSet r = ...........
BLOB b = (BLOB)r.getBlob('ICON');//BLOB is oracle type not Blob
byte[] base = b.getBytes();
Strgin res = Base64.encode(base);
//other side
String dec = datos;// data in base64
byte[] base = Base64.decode(dec.getBytes());
BLOB b = null;
b.setBytes(base);
is this code correct????
i tried to test but a have an error with
public static void BLOBToFile(BLOB datos,String path)
try
FileOutputStream fos=new FileOutputStream(path);
byte[] tempBin=new byte[8];
long cant=1;
while (cant <= datos.length())
tempBin=datos.getBytes(cant,Integer.MAX_VALUE);
cant = Integer.MAX_VALUE+1;
fos.write(tempBin);
fos.close();
catch(Exception e)
e.printStackTrace();
and the error is outOfMemory
how can i test my code??

File saveAsOpen and Base64 encoding...

In order to send the activeDocument to a web service, i need to save is as a file image, and send in an xml format.
Thus, i also need to encode it in Base64.
At this point everything is OK.
But between the saveAs of the file, its reopening, and its encoding, its corrupted.
I receive an error on the Mongrel server.
The Base64 encoder seems to work well, the rest of the code seem to be also ok, so I think my problem is either I do not save it correctly, either i do not reopen it correctly...
Please save me :(
Here is the code :
 /* STEP 1 : save current document as image file (temporary) */
 var docRef = activeDocument;
 var filepath=app.path.toString()+"/"+docRef.name+".jpg";//create the image file in the installation folder of Photoshop
 var file = new File(filepath);
 //var options = new ExportOptionsSaveForWeb();
 //options.format = SaveDocumentType.PNG;
 var options = new JPEGSaveOptions();
 options.quality=8;
 docRef.saveAs (file, options, true, Extension.LOWERCASE);
 //docRef.exportDocument (file, ExportType.SAVEFORWEB , options);
 file.close();
/* I code here dialogBox and httpCOnenction object creation
that do not need to be written here
(but if you think it's important, i can give you the full script)
 var f= new File(filepath);
 f.open();
 var buffer = f.read(f.length);
 f.close();
I build an HttpConnection object called "send"
*/ send.request='"+f.name+""+f.length+""+base64encode(buffer)+"';
Here is the Server error :

Base64 encode and image

Hi there
I am writing an adobe air app in html/javascript and I am trying to base64 encode an image so I can add it to and XML RPC request. I have tried many methods and nothings seems to work.
I see that actionscript has a Base64Encoder class that look like it would work, is there any way to utilize this in javascript?
Thanks,
Jordan

Reading it in as an ASCII string loses information - you're much better off reading it in byte-for-byte. Then you can send it as the serializeable of your choice (even a BigInteger would work).

How to convert a base64 encoded string to binary?

Hi, gurus,
I want to convert a base64 encoded string (a image which is read from a xml file)
into a normal binary string and then upload to archive link.
could you pls give me some hints on that?
br.
jun

thank you for your quick reply!
my real requirement is to extract an image(it 's said it's encoded using base64?) from a xml file and upload it sap archive linke,
following is the xml content, does that mean i need to convert all the chars in the
<mime_content> pair to your fm, that will be convert to binary string?

Converting Base64 encoded String to String object

Hi,
Description:
I have a Base64 encoded string and I am using this API for it,
[ http://ws.apache.org/axis/java/apiDocs/org/apache/axis/encoding/Base64.html]
I am simply trying to convert it to a String object.
Problem:
When I try and write the String, ( which is xml ) as a XMLType to a oracle 9i database I am getting a "Cannot map Unicode to Oracle character." The root problem is because of the conversion of the base64 encoded string to a String object. I noticed that some weird square characters show up at the start of the string after i convert it. It seems like I am not properly converting to a String object. If i change the value of the variable on the fly and delete these little characters at the start, I don't get the uni code error. Just looking for a second thought on this.
Code: Converting Base64 Encoded String to String object
public String decodeToString( String base64String )
byte[] decodedByteArray = Base64.decode( base64String );
String decodedString = new String( decodedByteArray, "UTF-8");
}Any suggestions?

To answer bigdaddy's question and clairfy a bit more:
Constraints:
1. Using a integrated 3rd party software that expects a Base64 encoded String and sends back a encoded base64 String.
2. Using JSF
3. Oracle 10g database and storing in a XMLType column.
Steps in process.
1. I submit my base64 encoded String to this 3rd party software.
2. The tool takes the encoded string and renders a output that works correctly. The XML can be modified dynamically using this tool.
3. I have a button that is binded to my jsf backing bean. When that button is clicked, the 3rd party tool sets a backing bean string value with the Base64 String representing the updated XML.
4. On the backend in my jsf backing bean, i attempt to decode it to string value to store in the oracle database as a XML type. Upon converting the byte[] array to a String, i get this conversion issue.
Possibly what is happen is that the tool is sending me a different encoding that is not UTF-8. I thought maybe there was a better way of doing the decoding that i wasn't looking at. I will proceed down that path and look at the possibility that the tool is sending back a different encoding then what it should. I was just looking for input on doing the byte[] decoding.
Thanks for the input though.
