POJO - Pictures, Blob ot byte[]

Hi All,
the POJO Reporting works fine but
How can i include a picture into my Report ??
If i move my object (with a Blob and byte[]) into myReport.rpt the Blob and the byte[] does not become available for reporting.
What is wrong ??
Thanks for Your help
René
My Object:
public class RhuPlakatData {
private String text11;
private Blob blob1;
private byte[] bytes;
public byte[] getBytes() {
return bytes;
public void setBytes(byte[] bytes) {
this.bytes = bytes;
public String getText11() {
return text11;
public void setText11(String text11) {
this.text11 = text11;
public Blob getBlob1() {
return blob1;
public void setBlob1(Blob blob1) {
this.blob1 = blob1;

Hi James
Unfortunately, I found no solution.
Did You found a solution??
Thanks for Your help
Greetings

Blob to byte[] detach failure

Hi,
I'm unable to detach a byte array using Kodo 3.3.4 and PostgreSQL 8.0. The
byte array in the detached object is always empty despite there being
bytes in the database table for the correspond column/row. Other fields
are detached correctly.
In my JDO file -
<field name="image">

<extension vendor-name="kodo" key="jdbc-field-map-name" value="blob">
<extension vendor-name="kodo" key="column" value="image"/>
</extension>
</field>
This correctly creates a column of named 'image' of type 'bytea' in the
table.
This issue isn't listed in the know issues for PostgresQL - can anybody
else confirm they have this working with this database? I see there was a
similar problem with mySQL posted here, but then that issue wasn't
documented either.
Thanks,
Andy.

byte[] fields aren't in the default fetch group by default, and
detachment only occurs on fields in the DFG. Both of these options
(whether the field is in the DFG, and whether detachment works on DFG
fields or uses some other criteria), are configurable. I assume you
know how to control DFG settings; the documentation on detachment is here:
http://www.solarmetric.com/Software/Documentation/latest/docs/ref_guide_remote.html#ref_guide_detach_graph

Exception getting blob to byte[]

Hy guys,
I 've a problem with my java application.
I use hibernate to interact with a derby database.
I stored a image into blob field (and no problem).
When I try to get blob to array of byte I've this exception:
java.sql.SQLException: You cannot invoke other java.sql.Clob/java.sql.Blob methods after calling the free() method or after the Blob/Clob's transaction has been committed or rolled back.To get blob I did
Blob cThumnb = ((Allegato) cAllegati.get(i)).getThumb();
byte[] cPrev = toByteArray(cThumnb);where
private byte[] toByteArray(Blob fromBlob) {
        ByteArrayOutputStream baos = new ByteArrayOutputStream();
        try {
            return toByteArrayImpl(fromBlob, baos);
        catch (SQLException e)

So could you cite some references that show, in general, that one normally needs to process blobs as streams?The design. The name, which is an acroynm for Binary Large Object. The fact that they have a stream interface, like files and sockets.The idiom for loading does not require nor even recommend that one must process as a stream.
And most of the time I do not process files nor sockets via streaming methodologies. I load them entirely, then process them.
Actually for direct socket usage, excluding protocols like FTP, I don't believe I have ever streamed processing because in message based protocols the messages are very small.
Presumably because the OP has one reference to 'thumb' as in thumbnail view?From the OP's first post: 'I stored a image into blob field'.I see. I have stored images in databases before. Excluding storage of medical media files they were all processed in memory because all were rather small.
Certainly cases where one does in fact want to read an entire file into memory, before one starts processing it.Can't think of any, but in any case if you are able to process it as a stream you are wasting both time and space by not doing so.If I have any data that is in fact "large" I will keep that in mind. But, for example, I can't see processing a configuration file that consists of a couple hundred bytes via stream processing just because files allow for the possibility that one can process a large file.

BLOB to byte[] mapping

Hi,
In my table, one of the columns is of type BLOB. When I generate Java objects out of the database, the type of this column becomes java.sql.Blob. This seems to be the default mapping. I want it to be of type byte[].
How do I configure Toplink Workbench to map it always as byte[]?

Either value in the object model is valid. You can modify the generated class to hold a byte[].
If you are using the Oracle thin JDBC driver you should map the byte[] attribute as a TypeConversionMapping and select the type to be java.sql.BLOB.

Please help, I need to read blob and output in bytes from wwv_flow_files.

Hi all,
I am having a requirement to read a blob stored in the oracle table and convert it into bytes. I am loading this table (wwv_flow_files) with APEX.
The code under page 1 is as follows:
DECLARE
z number;
y varchar2(4000);
x varchar2(400);
b blob;
BEGIN
select filename,blob_content into x ,b from APEX_APPLICATION_files where name =:P1_FILE_NAME;
select length(convertBlobToBytes(b)) into z from dual;
:P1_RESULT := z;
end;
Java code is as follows:
import java.io.*;
import java.sql.Blob;
public class convertBlob {
* @param blob
* @return
public static byte[] convertBlobToBytes(Blob blob) {
if (blob==null) return null;
try {
InputStream in = blob.getBinaryStream();
int len = (int) blob.length(); //read as long
long pos = 1; //indexing starts from 1
byte[] bytes = blob.getBytes(pos, len);
in.close();
return bytes;
catch (Exception e) {
System.out.println(e.getMessage());
return null;
PL/SQL wrapper is as follows:
CREATE OR REPLACE FUNCTION convertBlobToBytes(p1 IN BLOB) RETURN LONG RAW AUTHID CURRENT_USER AS LANGUAGE JAVA NAME 'convertBlob.convertBlobToBytes(java.sql.Blob) return byte[]';
I loaded this java class and pl/sql wrapper into the database using JDEVELOPER.
But I am getting the length of the file, as twice the size.
For example, When I run the program which reads the file returns the length of the file as a byte array, the length is 819.
When I pass the same file as a blob from apex, to the java program that converts blob to bytes, the length of the file is 1638.
And hence I am getting wrong results, further in the process.
Can you please help me? Any help is appreciated.

Oracle error ORA-01461when trying to insert into an ORACLE BLOB field

I am getting Oracle error ‘ORA-01461: can bind a LONG value only for insert into a LONG column' when trying to insert into an ORACLE BLOB field. The error occurs when trying to insert a large BLOB (JPG), but does not occur when inserting a small (<1K) picture BLOB.(JPG). Any ideas?
BTW, when using a SQL Server datasource using the same code.... everything works with no problems.
ORACLE version is 11.2.0.1
The ORACLE datasource is JDBC using Oracle's JDBC driver ojdbc6.jar v11.2.0.1 (I also have tried ojdbc5.jar v11.2.0.1; ojdbc5.jar v11.2.0.4; and ojdbc6.jar v11.2.0.4 with the same error result.)
Here is my code:
<cfset file_mime = Lcase(Right(postedXMLRoot.objname.XmlText, 3))>
<cfif file_mime EQ 'jpg'><cfset file_mime = 'jpeg'></cfif>
<cfset file_mime = 'data:image/' & file_mime & ';base64,'>
<cfset image64 = ImageReadBase64("#file_mime##postedXMLRoot.objbase64.XmlText#")>
<cfset ramfile = "ram://" & postedXMLRoot.objname.XmlText>
<cfimage action="write" source="#image64#" destination="#ramfile#" overwrite="true">

</cfquery>

Can't you use "alter index <shema.spatial_index_name> rebuild ONLINE" ? Thanks. I could switch to "rebuild ONLINE" and see if that helps. Are there any potential adverse effects going forward, e.g. significantly longer rebuild than not using the ONLINE keyword, etc? Also wondering if spatial index operations (index type = DOMAIN) obey all the typical things you'd expect with "regular" indexes, e.g. B-TREE, etc.

Joe,
a) I could not find updateBlob(int, java.io.InputStream). It is updateBlob(int, java.sql.Blob).
b) I tried the below test and it worked fine, I am using the latest drivers.
CREATE TABLE BLOB_TABLE (C1 NUMBER, C2 BLOB);
INSERT INTO BLOB_TABLE VALUES(55, '101011');
public static void test2(Connection conn) throws SQLException {
System.out.println("test -");
PreparedStatement pstmt = null;
ResultSet rs = null;
try {
String query = "select c1, c2 FROM blob_table";
pstmt = conn.prepareStatement(query, ResultSet.TYPE_SCROLL_INSENSITIVE,
ResultSet.CONCUR_UPDATABLE);
rs = pstmt.executeQuery();
SQLWarning x = pstmt.getWarnings();
if (x != null)
System.out.println(x.getMessage());
x = rs.getWarnings();
if (x != null)
System.out.println(x.getMessage());
BLOB blob = BLOB.createTemporary(conn, true, BLOB.DURATION_SESSION);

BLOB insert behavior with thin driver using standard JDBC2.0 and ORACLE-JDBC2.0API

We have a problem with a BLOB insert to an oracle 8.1.7 DB using Oracle 8.1.7 JDBC thin driver.We get socket read/write error after inserting 32k of data using the standard JDBC2.0 API but using the Oracle JDBC2.0API (using OracleResultSet) it goes fine. We have a requirement to use the standard JDBC2.0 so that our code works with multiple database vendors. Is there another way to get in the blob data with standard JDBC API & using thin driver...?

Thanks for the response.
I understand what you are saying...
that readers don't block writers in Oracle (the same is true in SQL Server 2000).
However, I don't see how my test case is working correctly with Oracle (the exact same code acting as I'm thinking it should with SQL Server, but I still think it is acting incorrectly with Oracle).
I have transaction A do this:
update <table> set <column2>=<value> where <column1>='1'
then I use Thread.sleep() to make that program hang around for a few minutes.
Meanwhile I sneak off and start another program which begins transaction B. I have transaction B do this:
select * from <table> where <column1>='1'
and the read works immediately (no blocking... just as you have said) however, transaction A is still sleeping, it has not called commit() or rollback() yet.
So what if transaction A were to call rollback(), the value read by transaction B would be incorrect wouldn't it ?
Both A and B use setAutoCommit(false) to start their transactions, and then call setTransactionIsolation(Connection.TRANSACTION_READ_COMMITTED).
Isn't that supposed to guarantee that a reader can only read what is committed ?
And if a row is in "flux"... in the process of having one or more values changed, then the database cannot say what the value will be ?
I can almost see what you are saying.
In letting the reader have what it wants without making it wait, I suppose it could be said that Oracle is holding true to the "only let committed data be read"
So if that's it, then what if I want the blocking ?
I want an entire row to be locked until whoever it in the middle of updating, adding, or removing it has finished.
Do you know if that can be done with Oracle ? And how ?
Thanks again for helping me.

hello,
there are multiple documents out there, describing the oracle reports server setup. try doc.oracle.com for documentation.
also it is part of the online-documentation.
you need to install 9iAS enterprise edition. the server is pre-configured and will listen to the url http://yourserver/dev60cgi/rwcgi60.exe
passing only this url you will get a help-screen, describing the syntax.
regards,
the oracle reports team

How to transfer a blob column in a table to another blob column in another

Well as the title suggest, i'm trying to take the BLOB field in say my table Photo and put it in another BLOB field in my table Members. How would i do that?
I'm working in Oracle Forms 10G.
I tried to do a cursor that get the picture(BLOB) and i tried to fetch the result in the other table :Members.Photo but it says my link is not good. I also tried using variables but didn't do the trick either.
The thing is we have a system that once the picture is taken its automatically put in the Photo table (contain only one picture at a time, only one row) and then in Forms we have have a message asking to press ok when the photo has been taken and then it should insert it in the Members table....
if more information is required please feel free to ask!
Thanks in advance.

INSERT INTO CLIENTS_PHOTOS (
CLPHOTO_ID,
CL_ID,
DTHRS_PHOTO,
PHOTO,
SIGNATURE,
CREE_LE,
CREE_PAR,
MODIFIE_LE,
MODIFIE_PAR
) SELECT :NOUVELLE_PHOTO.CLPHOTO_ID,
          CLIENT.CL_ID,
          SYSDATE,
          PS.PHOTO,
          PS.SIGNATURE,
          SYSDATE,
          :NOUVELLE_PHOTO.L_CD_USER,
          SYSDATE,
          :NOUVELLE_PHOTO.L_CD_USER
     FROM PHOTO_SIGNATURE PS;Looks quite ok so far. Did you try to issue that insert manually in SQL*plus? Also, is it correct that there is no WHERE-condition in your select?

Displaying BLOB from Database

Hi All,
I am trying to preview a 'jpeg' image which is stored in my database. The images get inserted into the DB without any trouble, but on retrieving the images I get 'broken links' to the images. Please Help:
PROCEDURE GET_TEAM_LOGO(team_name VARCHAR2)
AS
vblob BLOB;
buf RAW(32000);
buf_size INTEGER := 32000;
offset INTEGER := 1;
len NUMBER;
mime_type VARCHAR2(30);
BEGIN
auth_proc;
-- get image_data and its mime type from the database
WHERE LOGO_ID=position;
htp.p('This is the value of team:'|| team_name ||'<br>');
SELECT logo_image, logo_type INTO vblob, mime_type
FROM LOGO_TABLE
WHERE group_name = team_name;
-- set the mime type for the http protocol
owa_util.mime_header('image/jpeg');
-- read the data with htp package
len:=dbms_lob.getlength(vblob);
WHILE offset < len LOOP
dbms_lob.read(vblob,buf_size,offset,buf);
htp.prn(utl_raw.cast_to_varchar2(buf));
offset:=offset+buf_size;
END LOOP;
-- check for exception
EXCEPTION
WHEN OTHERS THEN
htp.p(SQLCODE || SQLERRM);
END;
Thanks,
Peter

Hi!
I've used this code successfylly in a mod_plsql procedure.
Can be used as following:
htp.img('http://yourhost:port/<dad>/image.get_image?p_picture_id=123,'"right"',null,null,'width=107 height=66 border=1');
procedure get_image
( p_picture_id number
) as
cursor c_pict
( b_picture_id number
) is
select pict.picture -- blob column
, pict.format -- Gif/Jpeg etc.
from pictures pict
where pict.picture_id = b_picture_id
r_pict c_pict%rowtype;
v_blob BLOB;
v_amt NUMBER := 30;
v_off NUMBER := 1;
v_raw RAW(4096);
begin
open c_pict(p_picture_id);
fetch c_pict into r_pict;
if c_pict%notfound
then
close c_pict;
else
close c_pict;
owa_util.mime_header('image/'||r_pict.format);
begin
loop
dbms_lob.read(r_pict.picture,v_amt,v_off,v_raw);
htp.prn(utl_raw.cast_to_varchar2(v_raw));
v_off := v_off+v_amt;
v_amt := 4096;
end loop;
exception
when no_data_found
then
null;
end;
end if;
end get_image;
