Store pdf in oracle BLOB hibernate

I need to store PDF files in the oracle BLOB using hibernate. I am using the below code and getting a null pointer. Any thoughts?
Blob blob=null;
byte [] bFile = (byte[])objVal;
blob.setBytes(0,bFile); //null pointer here...
logger.info("EventsDAO- insertDetails- else:--"+((byte[])objVal)+"---blob----"+blob);
hmForm.put(objKey,blob); Thanks in advance.

Samples? Are you asking how to make a blob? I have my doubts about the wisdom of using Hibernate if you can't diagnose a NPE unless that was just momentary code snow-blindness, but whatever, it's your problem:
Either call Hibernate.createBlob(InputStream,long) or just map the field as a byte[] and map it to a Blob type.

Error while trying to store PDF in Oracle's BLOB field

Hi folks!
I'm having problems while trying to store PDF file in a BLOB field of an Oracle table
This is the message code:
Exception in thread "main" java.sql.SQLException: Data size bigger than max size for this type: 169894
at oracle.jdbc.dbaccess.DBError.throwSqlException(DBError.java:134)

This is the piece of code i'm using:
Assuming conn = conection to Oracle 10g Database ( it's working )
String miProcedimientoAlmacenado = "{ call package_name.update_client(?,?, ?) }";
CallableStatement miComando = conn.prepareCall(miProcedimientoAlmacenado);
miComando.setString(1,miClienteID ); //first parameter : IN
               //second parameter : IN
File miPDF = new File(pathPDF + "//" + miClienteID + ".pdf");
byte[] bodyIn = readFully(miPDF); //readFully procedure is shown below
miComando.setBytes(2, bodyIn); //THIS IS THE LINE WHERE THE ERROR IS PRODUCED
          //3rd parameter: OUT
miComando.registerOutParameter(3, java.sql.Types.VARCHAR);
miComando.execute();
private static byte[] readFully(File miPDF) throws FileNotFoundException, IOException {
FileInputStream fis = new FileInputStream(miPDF);
byte[] tmp = new byte[1024];
byte[] data = null;
int sz, len = 0;
while ((sz = fis.read(tmp)) != -1) {
if (data == null) {
len = sz;
data = tmp;
} else {
byte[] narr;
int nlen;
nlen = len + sz;
narr = new byte[nlen];
System.arraycopy(data, 0, narr, 0, len);
System.arraycopy(tmp, 0, narr, len, sz);
data = narr;
len = nlen;
if (len != data.length) {
byte[] narr = new byte[len];
System.arraycopy(data, 0, narr, 0, len);
data = narr;
return data;
}//fin readFully
This approach indicates that the PDF file is converted into an array of bytes, then is stored as binary in the BLOB field.
Thanx in advance, and looking forward for your comments.

You will probably need to use the setBinaryStream() method instead of setBytes().

How to store PDF file in BLOB column without using indirect datastore

Hi ,
I want to store a pdf file in a BLOB column.
But , it should be a direct store. I cannot usre indirect datastore.
BLOB column doesn't support indirect datastore. I get the following error.

How to store pdf into blob, index it and search it?

I am trying to store pdf into a column, index the column and search it.
I store pdf file into blob column with either the following code or with an interface in apex
declare
Dest_loc BLOB;
Src_loc BFILE := BFILENAME('DIR_TESTCASE', 'intermedia.pdf');
BEGIN
INSERT INTO pdffiles(id, description)
VALUES(1, 'InterMedia Concepts')
RETURN text INTO Dest_loc;
DBMS_LOB.FILEOPEN(Src_loc, DBMS_LOB.LOB_READONLY);
DBMS_LOB.LOADFROMFILE(Dest_loc, Src_loc, dbms_lob.getlength(Src_loc));
DBMS_LOB.FILECLOSE(Src_loc);
COMMIT;
END;
then i need to create an index
begin
ctx_ddl.create_preference('pdf
lexer', 'BASICLEXER');
ctx_ddl.set_attribute('pdf_lexer', 'printjoins', '_-');
end;
create index PDFFILES_TEXT on PDFFILES(TEXT) indextype is ctxsys.context
parameters ('lexer pdf_lexer');
sqlplus says index created but windows gives an error and closes ctxhx.exe
and of cource when I tried to make a search like
select id, description
from pdffiles
where contains(text,'Oracle') > 0;
it doesn't return any results.
My database is 10g XE, I also tried it on Oracle 10.2.0.3 EE

It is possible to store pdf and doc files in a blob column, create a text index, and search them, and display them. However, you cannot expect to just select doc and pdf data directly from a blob column and expect to be able to read it, due to all of the special formatting characters. You need to use ctx_doc.snippet or ctx_doc.markup or some such thing to format it and make it readable. Please see the demonstration below. You can search the online documentation for complete syntax, additional information, and examples.

Can I store pdf in blob, and still search words in the pdfs?Probably not, no. If you want to search the data inside Oracle, you'll want to look at Oracle Multimedia.I think the correct answer is "not efficiently". :-)Well, there is nothing that prevents you from building Oracle Multimedia yourself and getting similar levels of efficiency. Other than a desire not to invest dozens of man-years replicating delivered functionality, of course.

How to store a PDF in a BLOB column, then select/search it using SQL?

We have a simple requirement.
(1.) We have an Oracle 10g DB.
(2.) We want to store PDFs/MS Word docs inside BLOB column in a table.
(3.) We need to show PDF/MS Word content to the user, without opening the PDFs/MS World like we normally do (i.e. Using PDV reader/ MS Word).
(4.) i.e. We need to use SQL statements and
(a.) Get all contents of the PDF/MS WORD doc.
(b.) Search for specific strings inside these docs in the BLOB columns.How to do this pls? Code sample would be really great.

@user12240205:
BLOBs contains binary data. Not text data. How do you propose to search binary data for strings?
PDF and Word formats include actual text strings and identifiers as part of the formatting. How do you propose that this be identified and ignored when searching for specific strings in the document's content?
PL/SQL does not have the ability to take a page from a PDF/Word document, highlight the search string, and display that to the client. A format-parser is needed to parse the PDF/Word format and generate that as content (e.g. HTML or XML) that can be rendered by a client. How do you propose PL/SQL serves up search strings that it found, when it cannot interpret the document format? (cannot even say what page, section or paragraph, that search string occurs)
Documents can be loaded via the DBMS_LOB interface. Either from the db server's file system, or by the client supplying the document as chunks for "write appending" to a BLOB. See Oracle® Database PL/SQL Packages and Types Reference guide for details.
Text search and document indexing are supported by an Oracle feature called Content Management<a> (which includes interMedia, UltraSearch, Oracle Text, etc).
Oracle also supports (on Window server platforms), the Microsoft Component Object Model (COM). COM interfaces (such as COM for Word) can be used for specialised processing (e.g. searching Word documents). Oracle's COM feature allows one to interface directly with external s/w (e.g. MS Word) via its COM interface.

Storing PDF as a BLOB on Oracle 9i

Hello,
I need to store a PDF document in ORACLE. I obvioulsy need to store it as a BLOB. I have created a BLOB filled in the table but I have no idea what to do next. Are there any good tutorials on this ? Can someone provide me a very simple code that inserts BLOB and than reads it?
Thanks

Dear All,
try this code it will store image or any file or pdf in to oracle database but,
the only thing you do is to put the table column type as 'LONG RAW'
It stores all the above as BLOBs.
try
// create connection
PreparedStatement pstmt = null;
File f = new File(file_path);
     FileInputStream fis = new FileInputStream(f);
     // System.out.println("IMG : "+file_name+" Len : "+f.length());
     String insert = "insert into table_name values(?)";
     pstmt = con.prepareStatement(insert);
     pstmt.setBinaryStream(1,fis,(int)f.length());
     i = pstmt.executeUpdate();
     fis.close();
     f = null;
          catch(Exception e)
               e.printStackTrace();
          finally
               try{
                    if(pstmt!=null)
                         pstmt.close();
                    if(con!=null)

Need guidence to store scan pdf in oracle 10g

Hello guru
I have 20000000 (2 corer) A4 size scan pdf containing text and images having
Average size 0f 0.5 mb. please guide me how can i store it in oracle database and what i have to do for same.
I am using oracle 10g forms as a front end for inserting & retriving scan pdf from database.
Regards
Vishal

Vishal,
Here are 2 options , first you can use either procedure or anonymous block to load clob data
First Method -- I loaded alert.log successfully and you can imagine how big this file can be (5MB in my test case), in your case you need to specify your pdf file. CLOB/BLOB can take upto 4GB data
Make sure you have privs to create , read or write to directory
create table t1clob (
clob_data clob -- you can use blob
CREATE OR REPLACE DIRECTORY DIR AS '/my_path_to_pdf_file/pdf';
DECLARE
   clob_data   CLOB;
   clob_file   BFILE;
BEGIN
   INSERT INTO t1clob
   VALUES (EMPTY_CLOB ())
   RETURNING clob_text INTO clob_data;
   clob_file   := BFILENAME ('DIR', 'wwalert_dss.log');
   DBMS_LOB.fileopen (clob_file);
   DBMS_LOB.loadfromfile (clob_data,
                          clob_file,
                          DBMS_LOB.getlength (clob_file)
   DBMS_LOB.fileclose (clob_file);
   COMMIT;
END;
Second Method: Use of Sqlldr
Example of controlfile
LOAD DATA
INFILE alert.log "STR '|\n'"
REPLACE INTO table t1clob
   clob_text char(30000000)
)Also check this link for more example

Hope this helps.

PDF binary variable won't save in Oracle blob

I am reading in a small, legitimate PDF as a binary variable and them immediately saving that variable into a blob. But the blob doesn't store the data.
<cffile action="readbinary" file="C:\Test_Files\test.pdf" variable="testdoc">
now shows isbinary(testdoc) = YES
In fact, I can output to the screen using cfcontent, and it displays fine.
But if I try to save the testdoc variable to an Oracle blob, CF seems to think it is trying to insert an empty variable.
<cfquery name="ins" datasource="#request.a_datasource#">
INSERT
INTO PROD_WCT.T_DOCS (
PDF_BLOB
VALUES (
<cfqueryparam value="#testdoc#" cfsqltype="CF_SQL_BLOB">
Now if I retrieve that row (query name=”get_pdf”) and check the value, it appears empty:
now shows isbinary(get_pdf.pdf_blob) = NO
Nothing is done in betweent the cffile and the insert. Any ideas?

Just an update here to note that this problem has not yet been resolved.
This could be in incompatibility between Oracle 10g BLOBs and Coldfusion 8.
To review, my BLOB setting in CFADMIN is enabled. To make this as simple and possible, I created a PDF from the words "Test text," so the PDF document can't get much smaller. The PDF does save to the BLOB, because in TOAD I can save the BLOB contents to a file and view it as a PDF just fine. It's when I retrieve the record in CF8 where the trouble arises. Coldfusion 8 doesn't get anything from the BLOB. It has a zero length, and isbinary = NO. We are using Oracle 10g. And using CF8. My understanding is that an Oracle blob uses pointers to locate the blob data in an area external to the database. Apparently, Coldfusion cannot retrieve the data. The process worked for the first few records when retrieving a blob and displaying it with cfcontent, but after a few records it can no longer retrieve the subsequent blob records. It just abruptly fails at that point. But again, the PDF binary data is there in TOAD.
Could this be a bug or incompatibility with Oracle 10g? We are a state government, and it sure would help if the Adobe people could give come help here.
Thanks in advance for any thoughts.

To store PDF into BLOB and retrieve into OLE/OCX

We would like to:
1. Store a PDF file (output of a report saved in file server) into a BLOB
column.
2. Retrieve previously stored PDF in the BLOB column and display using either
OLE automation or ActiveX (OCX) control.
I read all related documents in metalink that addresses this issue however cant
get this to work. We have Acrobat Reader 4.0. Here are some issues from the
tests that I did:
1. To load the PDF file the program code that uses BFILE and LOADFROMFILE does
not work since the database is on a remote server and the PDF file is on a
local file server. The DIRECTORY created on the database is unable to find the
PDF file.
2. Though I want the loading of the file to be programmatic, I tried
right-click on the OLE container and inserted object from file. This loaded the
file into the container (Icon on the container appeared) however I was not able
to view the document by double-clicking. An error in Adobe occured: 'There was
an error opening this document. A file read error occured'. My guess is the
'Insert Object' did not insert the file properly into the BLOB.
3. When trying to display the PDF file stored in file server (in case storing
into BLOB does not work), I used an OCX control, right-clicked and Insert
Object and select Adobe Control for ActiveX. The problem here is when I run the
form, the OCX control shows up empty and I have to 'Insert Object' again in
runtime. Once I manually insert object from runtime the GET_INTERFACE POINTER &
SET_PROPERTY works fine is displaying the document. Is there any way to
maintain the control property of the OCX when the form is run?
4. Are there any workarounds and better solution to store PDFs into BLOBs and
retrieve and display in OLE/OCX controls? Using temporary file into local drive
is not an issue.
5. Would I be able to make use of 'PDF.PdfCtrl.1' OLE class?
6. Does OLE automation work for Acrobat Reader 4.0.?
I would appreciate all the help.

Im facing a similar kind of problem. I want to store and retrieve Office files, PDF and Jpegs into/from the database to view them on web in disconnected mode. Please reply as I cant find any help/documentation regarding saving BLOB data into files. I was able to store file data into BLOB, using DBMS_LOB package.

Downloading a PDF document via blob won't open start acrobat on click

I'm experiencing a problem trying to get acrobat reader to open immediately when viewing a file stored as a blob is clicked. I am updating an old plsql webtoolkit app that stores pdf files in the database as a blob and displays them to the user in a frame. Download is achieved using wpg_docload.download_file() and the example provided by Oracle documentation. The download package body is:
BEGIN
l_filename := SUBSTR(OWA_UTIL.get_cgi_env('PATH_INFO'), 2);
-- get mime type from db
SELECT blob_content,
         mime_type
INTO   l_blob_content,
         l_mime_type
FROM   documents
WHERE name = l_filename;
-- Add header
HTP.init;
OWA_UTIL.mime_header(l_mime_type, false);
HTP.print('Content-Length: ' || DBMS_LOB.getlength(l_blob_content));
HTP.print('Content-disposition: inline; filename="'|| l_filename ||'"');
OWA_UTIL.http_header_close;
-- get document
WPG_DOCLOAD.download_file(l_blob_content);
EXCEPTION
WHEN OTHERS THEN
    HTP.htmlopen;
    HTP.headopen;
    HTP.title('File Downloaded');
    HTP.headclose;
    HTP.bodyopen;
    HTP.header(1, 'Download Status');
    HTP.print('Download of ' || l_filename || ' failed.');
    HTP.print(SQLERRM);
    HTP.bodyclose;
    HTP.htmlclose;
END download;All files will download okay but the acrobat container doesn't open right away and show a progress bar. It waits for the entire file to download, then opens the file. This becomes a bigger issue when the file size increases because it appears as though the site hangs until the document appears.
If I place a file on a site directory instead of inside the database, create a link to it and click it, acrobat opens right away and displays progress. I want to get the site to open blob stored files in adobe right away and show download progress as if the file was stored on a site folder.
Any ideas? Thanks

Add this line to the content header
HTP.print('Accept-Ranges: bytes');
