Decode Base64(Pdf) to binary

Hi all,
I have a WS - PI - File scenario.
So I get a base64 coded PDF-File and have to create a decoded binary file.
First I used an UDF. But the created document is invalid and not to open by Acrobat. After reading the forum the conclusion is, it is impossible to convert data in mapping step, is'nt it.
But what are the other possibilities?
Regards
Mathias

You can do this in the mapping using Base64.decode() method from SAP standard API (com.sap.aii.utilxi.base64.api.*)
Check my WIKI section for ref: [Sending Binary Data to Inbound Plain HTTP Adapter in XI and PI |http://wiki.sdn.sap.com/wiki/display/XI/SendingBinaryDatatoInboundPlainHTTPAdapterinXIand+PI] where i used encode method in HTTP client code.
You can check decode method code in the java snippet "Java Mapping - Base64 Decryption and Unzipping Code "

Hi,
This is the encoded base64 file in XML format:

Can i pass all these characters or i need to transform it first, extract the value of the element and decode? Finally i need to write the decoded outcome to a file (a pdf file) to the hard drive (may be with: OPEN DATASET P_DATASET FOR INPUT IN TEXT MODE ENCODING DEFAULT)
I saw this hint but I think there should be more to it (eg. transformation of the initial decoded xml file and the writing it to hard drive using the Open Dataset for Input...):

i need to decode base64 attachments.
However the funciton modules i would normally use are not available in 4.6c does anyone know how i can do it ?

I found a solution in 4.6C which works out of the box: (See form in s_trustmanager)

PDF to Binary

Hi,
I create a Adobe Interactive Form, I need to display this PDF in SAP portal, then I need to develop a RFC to return this PDF file, I read in other post that the way is to convert de PDF to binary file a return this binary file like a paremeter in the RFC.
Someone have an example about this?
Regards
Eduardo Campos

This works for me, it copies an excel file into another excel file.
You can keep the binary information as long as you want and later download the file to another place.
You can try it to see if it works for you.
Remember to keep the file lenght.

Edit: Sorry, didn't read the question right.
Well, is almost the same way, just use Open dataset dsn in binary mode. That way you'll get your file in binary mode.
I was supossing you were usen a local file but now I see you want it in the application server

Decode Base64 and save as binary file

Hi there,
I am using Adobe Air 1.5 with JavaScript and want to save a file to my hard
drive. I get the data from a WebService via SOAP as a Base64 encoded string. A test-string is attached. When I try to decode it with
the WebKit function "atob()" and try to save this bytes with following code, I can't open the file.
this.writeFile = function(outputfile, content, append){
var file =a ir.File.applicationStorageDirectory.resolvePath(outputfile);
var stream = newa ir.FileStream();
if (append) {
stream.open(filea, ir.FileMode.APPEND);
}else {
stream.open(filea, ir.FileMode.WRITE);
try{//Binärdaten
stream.writeBytes(content0, , content.length);
}catch(e){//Textdaten
stream.writeUTFBytes(content);
stream.close();
The same happens when I try to open a file from my HDD and read in the bytes. When I decode it to base64, the string is not equal to the string, which is correct.
I attached a working Base64 string, which I could convert back to a zip-file via a only encoder.
So my question is, how can I decode a Base64 string and save the binary data to a file?
Thank you for your help.

I rewrote the Base64 decoder/encoder to use it with a ByteArray. Here ist the code:
var byteArrayToBase64 = function(byteArr){
    var base64s = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/";
     var encOut = "";
    var bits;
    var i = 0;
    while(byteArr.length >= i+3){
        bits = (byteArr[i++] & 0xff) << 16 | (byteArr[i++] & 0xff) << 8 | byteArr[i++] & 0xff;
          encOut += base64s.charAt((bits & 0x00fc0000) >> 18) + base64s.charAt((bits & 0x0003f000) >> 12) + base64s.charAt((bits & 0x00000fc0) >> 6) + base64s.charAt((bits & 0x0000003f));
    if(byteArr.length-i > 0 && byteArr.length-i < 3){
        var dual = Boolean(byteArr.length - i - 1);
        bits = ((byteArr[i++] & 0xff) << 16) | (dual ? (byteArr[i] & 0xff) << 8 : 0);
        encOut += base64s.charAt((bits & 0x00fc0000) >> 18) + base64s.charAt((bits & 0x0003f000) >> 12) + (dual ? base64s.charAt((bits & 0x00000fc0) >> 6) : '=') + '=';
    return encOut;
var base64ToByteArray = function(encStr){
    var base64s = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/";
     var decOut = new air.ByteArray();
    var bits;
    for(var i = 0, j = 0; i<encStr.length; i += 4, j += 3){
        bits = (base64s.indexOf(encStr.charAt(i)) & 0xff) <<18 | (base64s.indexOf(encStr.charAt(i +1)) & 0xff) <<12 | (base64s.indexOf(encStr.charAt(i +2)) & 0xff) << 6 | base64s.indexOf(encStr.charAt(i +3)) & 0xff;
        decOut[j+0] = ((bits & 0xff0000) >> 16);
          if(i+4 != encStr.length || encStr.charCodeAt(encStr.length - 2) != 61){
               decOut[j+1] = ((bits & 0xff00) >> 8);
          if(i+4 != encStr.length || encStr.charCodeAt(encStr.length - 1) != 61){
               decOut[j+2] = (bits & 0xff);
    return decOut;

Possible to decode base64 document contents to XDP?

Hi,
As the title says, is it possible to decode the base64-encoded contents of my PDF back to an XDP format?
Using this JavaScript SOAP.stringFromStream(SOAP.streamEncode(Collab.documentToStream(event.target), "base64")); I am able to submit the base64 encoded PDF document to my server side for processing. Is there any way to convert this back to XDP format at this stage?
Thanks,
Ray

Maybe someone might have a few ideas on how I can approach my problem so.
My web application maintains session info of any logged in users. One of the attributes of the session is a "securityToken".
When the user clicks a button on the PDF within my web application, a Web Service call is made. However, I need to get the securityToken into this Web Service call. This securityToken isn't something that the user should be manually entering.
Can anyone think of any possible solution to solve this problem?
Thanks,
Ray.

BASE64 (PDF) CLOB to BLOB

Hello everybody! I have to convert a BASE64 representation of a PDF file to BLOB. I found one example on the Internet but there is something wrong with it and I can't figure it out.
create or replace function decode_base64(p_clob_in in clob) return blob is
v_blob           blob;
v_offset         integer;
v_buffer_varchar varchar2(32000);
v_buffer_raw     raw(32000);
v_buffer_size    binary_integer := 32000;
begin
if p_clob_in is null then
return null;
end if;
dbms_lob.CREATETEMPORARY(v_blob, true);
v_offset := 1;
FOR i IN 1..CEIL(dbms_lob.GETLENGTH(p_clob_in) / v_buffer_size)
loop
dbms_lob.READ(p_clob_in, v_buffer_size, v_offset, v_buffer_varchar);
v_buffer_raw := utl_encode.BASE64_DECODE(utl_raw.CAST_TO_RAW(v_buffer_varchar));*
dbms_lob.WRITEAPPEND(v_blob, utl_raw.LENGTH(v_buffer_raw), v_buffer_raw);
v_offset := v_offset v_buffer_size;+
end loop;
return v_blob;
end decode_base64;
The above procedure should work with files of any size (since there is a loop), but it only works when the PDF is smaller than 32 KB.

Just a guess.
You may have additional CRLFs added when encoding.
Try this:
create or replace function replaceClob (opCLob CLOB,cpReplaceStr VARCHAR2,cpReplaceWith VARCHAR2) RETURN CLOB IS
   cBuffer    VARCHAR2 (32767);
   nBuffer    BINARY_INTEGER := 32767;
   nStart     PLS_INTEGER := 1;
   nLen            PLS_INTEGER;
   oCRtn      CLOB := EMPTY_CLOB;
   BEGIN
     DBMS_LOB.CreateTemporary(oCRtn,TRUE);
     nLen := DBMS_LOB.GetLength(opCLob);
     WHILE nStart < nLen
     LOOP
       DBMS_LOB.Read(opCLob, nBuffer, nStart, cBuffer);
       IF cBuffer IS NOT NULL THEN
         cBuffer := REPLACE(cBuffer, cpReplaceStr, cpReplaceWith);
         DBMS_LOB.WriteAppend(oCRtn, LENGTH(cBuffer), cBuffer);
       END IF;
       nStart := nStart + nBuffer;
     END LOOP;
     RETURN oCRtn;
   END;and then add to your code:
create or replace function decode_base64(p_clob_in in clob) return blob is
       v_blob blob;
       v_offset integer;
       v_tem_clob clob;
       v_buffer_varchar varchar2(32000);
       v_buffer_raw raw(32000);
       v_buffer_size binary_integer := 32000;
       --v_buffer_size binary_integer := 3*1024;
       begin
       if p_clob_in is null then
          return null;
       end if;
       -- Add this line
       v_tem_clob := replaceClob(p_clob_in,UTL_TCP.CRLF,'');
       dbms_lob.CREATETEMPORARY(v_blob, true);
       v_offset := 1;
       FOR i IN 1..CEIL(dbms_lob.GETLENGTH(v_tem_clob) / v_buffer_size) loop
           dbms_lob.READ(v_tem_clob, v_buffer_size, v_offset, v_buffer_varchar);
           v_buffer_raw := utl_encode.BASE64_DECODE(utl_raw.CAST_TO_RAW(v_buffer_varchar));
           dbms_lob.WRITEAPPEND(v_blob, utl_raw.LENGTH(v_buffer_raw), v_buffer_raw);
           v_offset := v_offset + v_buffer_size;
       end loop;
       return v_blob;
end decode_base64;Not tested.

Parse xml in inputstreamobject and decode base64

Hello
I have got a http-package with content-type text/xml, from a HttpURLConnection object.
From the HttpURLConnection object i get an InputStreamObject.
Now i'm looking for the easiest to parse the xml, that is in the Inputstream object.
The xml just contains base64 encoded data and i need to decode this data into a byte array.
I have not much experience with java and xml, so it would be nice when somebody could help me.
Kind regards,
ClaudeMichelle

The xml just contains base64 encoded data and i need to decode this data into a byte array.Below tutorial will help.
BASE64 Decoder Stream from Sun Microsystems:*
This class implements a BASE64 Decoder. It is implemented as a FilterInputStream, so one can just wrap this class around any input stream and read bytes from this filter. The decoding is done as the bytes are read out.

How To formate PDF Data(Binary) to HTML Formate

Hi All,
I am using PDFs in my application. Once the user has submitted his project in formation through pdf, it stores in BAPI. When i tried to retrive the data from back end to display in a view. it shows me all the information is in single line because of PDf binary data. Can any one knows about how to display pdf data in a view (html) with multiple lines.
Thanks
Regards

PDF to binary: Scenario R/3 to MQSeries

The JMS adapter transfers the message payload from and to the MQSeries whithout any change.
I am not sure, what you want to have as result, when you mention "binary".
Any file is binary, even an XML file
The next question is: When you read a PDF, what do you want with it?
The easiest thing is, sending the PDF through PI to MQSeries without any change. Then you receive just the original PDF.

Hi
check this thread
spool to pdf conversion
It looks like you are missing translate in you processing of the table t_pdf. Something like the following line is missing:
TRANSLATE gd_buffer USING '~ '.
Loo at the standard program RSTXPDFT4 as well. It converts spool to PDF and then you can download it to your desktop.

Hi,
Below is the code which may help you out.
***Retrieve your Pdf source in Onclick event of submti button.
DATA lo_el_context TYPE REF TO if_wd_context_element.
DATA ls_context TYPE wd_this->element_context.
DATA lv_pdfsource LIKE ls_context-pdfsource.
* get element via lead selection
lo_el_context = wd_context->get_element( ).
* get single attribute
lo_el_context->get_attribute(
    EXPORTING
      name = `PDFSOURCE`
    IMPORTING
      value = lv_pdfsource ).
Convert to Binary using below code..
DATA: p_image TYPE sdokcntbins.
DATA: p_image_len TYPE i.
CLEAR: p_image_len.
REFRESH p_image[].
CALL FUNCTION 'SCMS_XSTRING_TO_BINARY'
    EXPORTING
      buffer                = lv_pdfsource
*   APPEND_TO_TABLE       = ' '
   IMPORTING
     output_length         = p_image_len
    TABLES
      binary_tab            = p_image[].
Now you can use this binary tab to update your custom table..

Decoding base64-encoded SSL files

There is a way to decode the base64 contents of .crt, .key, and .pem files to display human-readable text, but I can't remember how to do it. "base64 -d" doesn't work cause there's some garble in there. I think I used the openssl command for this. Anyone know?

Is this what you are looking for? http://www.madboa.com/geek/openssl/#cert-exam

quick response expected.

it's most likely the text you're extracting from the database is either corrupted or wasn't encoded as you expect. Note that your success with the img tag decoding may be misleading. I can't give you details that apply to this case, but browsers typically use smarter decoding tools which are more robust ...
1) Was the text in the database produced by an internal encoder or was it obtained either from a standard e-mail attachment or produced by this command or its equivalent?:
Thanks Ray - I was afraid of that. I am extracting the image from a database written by a commercial application. I checked with the developers, and they said it was base64, so that's all I have to go on. I reported this anomaly to them but haven't heard back in over a week.
2) Are you sure you're retrieving exactly the same bytes that were stored in the database?
As sure as I can be. For testing, I invoke sqlite from a shell to do the select statement and dump the result to the terminal. Then copy and paste from terminal to a TextWrangler document. I have done the same with an Applescript.
One complicating factor: the text stored in the database has these weird markup tags that I can't find any documentation. They look like this: <iimg><preferredFilename>Embedded image</preferredFilename><segment>TU0AK...=
</segment><segment>UdSVL...=
</segment></iimg>
I strip these out of the field coming from the database.
To isolate the problem...
Unfortunately, since I am not creating the database, I am loath to write to it. I could, but since the problem is likely in the way the developers are encoding or storing the data, it wouldn't do much to solve my problem...
Thanks so much for your suggestions!! Very helpful.

Mdimportserver[2762]: *** Failed to decode data, treating as binary Error

Can anyone help me understand how to troubleshoot this error. I am finding a large % of my CPU consumed by inactive processes [update / mds / configd / cupsd]. I do not touch these, and I am not sure how to resolve this conflict (if it is even one). Any help in working on the next steps would be much appreciated.

Hi Joshua,
Do you have anything in this folder...
/Users/YourUserName/Library/InputManagers
Like SIMBL perchane?
It could also be a few other things since mdimport server is Spotlight.
Try resetting or redoing the Spotlight files with Spotless...
