Refcursor returning image (BLOB type) from database

Hi,
Process : Invoke activity takes ID as input parameter and passes it to partner link (db adapter) which executes stored proc returning a ref cursor. SQL statement in stored proc - ref cursor has a column with BLOB type.
Problem : Unable to return an image (defiined as BLOB type in database) through refcursor in BPEL.
Error : Unable to convert XSD element Column whose JDBC type is BLOB to a corresponding XML document element.
ORABPEL-11087
XSD :
<complexType name="RowSet">
<sequence>
<element name="Row" minOccurs="0" maxOccurs="unbounded" nillable="true">
<complexType>
<sequence>
<element name="Column" maxOccurs="unbounded" nillable="true">

Need Solution : To get an image (of BLOB type) into BPEL using ref cursor.
Please let me know if you need any more information to get it working.

Write blob data from database to unix server

Hi all,
I need to send the attachment file into the mail. I have a header form in which I have implemented Download/Upload functionality using Apex user guide. When ever a user fill all the entries and submit the form then some field information along with attachment I need to send to the user.
I mean when ever user hit the submit button it should take blob data from my custom table tmp_downlod_files and send to the user as an attachment.
I have searched the post and got lot information but not able to get succeed.
I have implemented java stored procedure for sending automatic mail when user is submitting the form but what I need is to take blob content from database and send as an attachment.
1: So I need to write blob content from custom table to unix server in some location and from there I need to attach that file.
2: the java store which I have implemented for sending automatic mail is working and one argument is attachment which I am passing null for now. So mail is working how to write the file from database to unix server and send as an attachment.

Returning an array type from a local method in Web Dynpro Java application

Hi,
In my project, we have a requirement to display 18 rolling months along with the year, starting from current month.
How I am going to approach is that I will get the system date and get the current month and send the month and year value to a local method which will return 18 rolling months along with the year.
But, when I tried to create a new method there is no option to return an array type. It was greyed out.
So, we can not return an array type from a method from Web Dynpro for Java application?
If so, what is the alternative and how am I going to achieve it?
I will appreciate your help!
Regards
Ram

HI
You can create new methods in
//@@begin others
private ArrayList MyMethod(){
// ** Put your code here
return new ArrayList();
//@@end
Other option are create a context node with cardinality 0...n with one or more attributes, and in your method create the needed registers into this node. To read this values, you only need to read your context node.
Best regards

Forms 6i - display into image item picture stored in blob type on database

hi to all
i searched on this forum but in don't found solution my problem.
I created table with a column blob and i design form that insert and display image stored in database ( oracle 9i )
i used image item type with block database based
my version forms is
Forms [32 Bit] Version 6.0.8.13.0 (Production)
if i define column table like "long raw" it worked but i used blob i insert but i don't display image
error is:
ORA-00932: inconsistent datatypes: expected got
thanks a lot to all
bye

I know, that the false forms-version (patch) gives you this errors. Try a newer patchset. For example patch 13-15 (for 9i), or 17 (10g rel. 1)

Download link to file saved in BLOB type in database

Hi all,
I have made a page where i am letting users upload a file in any format, and i'm saving it to database in BLOB datatype field of a table.
The filetype is also saved in a different column of the table.
Now I want to retrieve the contents back in that particular format by converting the data in BLOB type to filetype.
And a link should be provided to download the file.
A little help can be taken from this link which uses EJB session to do the same thing.

Hi,
My requirement is that in the database table images gets saved of type BLOB and i have to display these images in my OAF page .I looked in OA developers guide and followed the instruction but unable to achieve my requirement .As per the developers guide "I created an item of type messageDownload ,in the viewattribute i set the view attribute FileData and File View Attribute FileContentType the table used is FND_LOBS" but i couldn't achieve anything.
Please help me and if possible give me exact way to achieve it as i am new to this framework.

Map the database table columns to the Table region columns. For image column set the item style as "Messagedownload". Set the View Instance (VO) , View Attibute Name (image name) and View Attribute Data (blob col).

ADF How to Download BLOB File from Database Column

Hi,
We have one blob Database Column in which we use for storing attachments(eg Image,.doc or.zip) . We are able to upload attachments.
How can I build page which will access that particular record and will be able to download attachment in it.
It should prompt to Save and then we can save it on Local machine.
Thanks,
Jit

Sorry, I don't get your question.
If you have a file name including the suffix like 'Test.file.doc' you can pass this file name as parameter to the method and get the MIME type back. I your sample it would be "application/msword"
String mime = ContentTypes.get("Test.file.doc");
public class ContentTypes
    public static String get(String fileName)
        String mime = null;
        String ext = fileName.toLowerCase();
        if (ext.endsWith(".pdf"))
            mime = "application/pdf";
        else if (ext.endsWith(".doc"))
            mime = "application/msword";
        else if (ext.endsWith(".xls"))
            mime = "application/msexcel";
        else if (ext.endsWith(".docx"))
            mime = "application/msword2007";
        else if (ext.endsWith(".xlsx"))
            mime = "application/msexcel2007";
        else if (ext.endsWith(".ppt"))
            mime = "application/vnd.ms-powerpoint";
        else if (ext.endsWith(".rar"))
            mime = "application/octet-stream";
        else if (ext.endsWith(".zip"))
            mime = "application/zip";
        else if (ext.endsWith(".jpg"))
            mime = "image/jpeg";
        else if (ext.endsWith(".jpeg"))
            mime = "image/jpeg";
        else if (ext.endsWith(".gif"))
            mime = "image/gif";
        else if (ext.endsWith(".png"))
            mime = "image/png";
        return mime;

Image on jsp from database along with other elements on image.

Hi All,
I wish to display an image which is stored in my database along with other contents on the page.
I am able to display the image on an entirely new page but I do not wish to display it on a new page. Neither frames etc fit on my current page design.
Kindly help

I have a jsp page ..
I have a byte stream in which i have stored the image from the database (the image is stored in databse as blob) in that jsp.When i use output stream object to display the image from the database (as suggested by many in this forum), the image is displayed in a new page. I wish to display the image along with my other elements like text etc in the same page.

ResultSet.getString(String) doesn't return the right text from database

Hi everybody,
I'm trying to read some text in Portuguese from a MS-Access database, but the special characters for Portuguese aren't correctly translated by ResultSet.getString(String).
Here's my piece of code:
private static void fetchEquipamentoEstabelecimento()
try
Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery(
" SELECT Eqp.NumSerie, Eqp.Estabelecimento, Estab.Nome, Estab.Cidade, Eqp.Data, Eqp.LPN " +
" FROM Equipamento Eqp, Estabelecimento Estab " +
" WHERE TabPreco = 23 " +
          " AND Eqp.Estabelecimento = Estab.Estabelecimento " +
"ORDER BY NumSerie DESC");
while(rs.next())
String nome = rs.getString("Nome");
System.out.println(rs.getLong("NumSerie")      + " " +
                         rs.getDate("Data")           + " " +
                         rs.getString("LPN")           + " " +
                         nome                              + " " +
                         rs.getString("Cidade"));
stmt.close();
catch(SQLException ex)
printSQLException("fetchEquipamentoEstabelecimento()", ex);
The output of this piece of code is 1 record joined from tables Equipamento and Estabelecimento:
111222333 2001-12-15 JHK Pal<X>cio Cristal Guarda
where the <X> is the greek letter beta. I was expecting a
portuguese character which is an a with an accent: � (I hope the character was correctly displayed for you)
I tried replacing
String nome = rs.getString("Nome");
with
String nome = new String(rs.getString("Nome").getBytes(),codepage);
with codepage="Cp860" (MS-DOS Portuguese)
and codepage="Cp037" (USA, Canada (Bilingual, French), Netherlands, Portugal, Brazil, Australia)
but other strange characters were displayed instead of the a with an accent.
In the MS-Access table Estabelecimento, the column Nome has a Data Type of Text.
I'm using:
- JDK 1.2.2
- MS Access 2000 (in Windows 2000)
MS Access 97 (in Windows NT 4.0).
Any help is deeply apreciated.

Hi!
When you establish connection to database, try explicitly give instructions about what encoding use your DB, e.g.:
// connection properties
Properties connInfo = new Properties();
connInfo.put("user", username);
connInfo.put("password", password);
connInfo.put("charSet", "Cp1251"); // enter your codepage!!!
// getconnection
Connection db = DriverManager.getConnection(dataurl, connInfo);

Is it possible to return an operator-type from a function/decode ?

Hi ,
I have a query that is calling a decode and based on the operator type (i.e <> , >= , <= etc ..) that it returns to compare 2 fields of a table
is this possible and if so could anyone advise me how to ?
below is my current declaration that gives invalid relational operator error
SELECT 1 into TmpCnt FROM Tbl1a where
a.id = ID and a.part = PART and a.parmn = TESTNAME
and a.paval DECODE(TESTCONDITION , 'LT' , '<' ,
'LE' , '<=' ,
'EQ' , '=' ,
'GE' , '>=' ,
'GT' , '>' ,
'NE' , '<>' ) TPARAMVALUE ';
tks & rdgs

You can't replace an operator with an expression.
For a limited number of operators you may be able to code this explicitly, something like...
SELECT 1
FROM   tbl1a
WHERE a.ID = ID
AND    a.part = part
AND    a.parmn = testname
AND    DECODE (testcondition,
         'LT', CASE WHEN a.paval <= tparamvalue THEN 'Y' END,
         'LE', CASE WHEN a.paval = tparamvalue THEN 'Y' END,
         'EQ', CASE WHEN a.paval >= tparamvalue THEN 'Y' END,
         'GE', CASE WHEN a.paval >= tparamvalue THEN 'Y' END,
         'GT', CASE WHEN a.paval > tparamvalue THEN 'Y' END,
         'NE', CASE WHEN a.paval != tparamvalue THEN 'Y' END) = 'Y'Otherwise you are looking at Dynamic SQL.

Display Images from Database

Hi all,
I require to display images stored in database along with textual description of it on a JSP.
The image file should not be stored intermediately on file system (i.e w/o using img HTML tag)
It is a typical shopping cart appln. where images are fetched from database and the associated description is displayed along side.
Please note that it is the case of Mixed content types(text and binary data).
Thanks and Regards

Like "Breakfast" said, you can do this with a servlet that retrieves your images from a database....
if you create a servlet to do this, you would have a generic servlet which retrieves a picture from a database based upon a key which could be a picture name or number.
Lets say the file is out there in the database as a BLOB or Binary Image... you could have this kind of code in the doPost(HttpRequest req, HttpResponse res) or doService(HttpRequest req, HttpResponse res) method.
The table holding the image has at least two columns one called IMAGE which holds the binary image and the other called FILENAME. If the connection to the DB is already open, you do something like this.
String fileToGet = (String)req.getParameter("FILENAME");
rs = conn.createStatement().executeQuery("select from IMAGE_TABLE where FILENAME='" + fileToGet + "'");
if(rs.next())
InputStream in = rs.getBinaryStream("IMAGE");
res.setContentType("image/jpg"); // or whatever type of file it is.
ServletOutputStream sout = res.getOutputStream();
int c;
while((c = in.read()) != -1)
sout.write(c);
in.close();
sout.close();
This should write your image to the response output of the servlet.
Now, where you want your image, you put.
<img src="/servlet/ImageServlet?FILENAME="thefileIwant">
This should do what you want... Use your favorite pipe copy method to get the input stream to the output stream. If you are worried about overhead and scaling like "breakfast" said (it CAN be a problem in high access sites), then you can add an image caching scheme and get really complex.... But this is a rough idea on what to do.
Hope this helps.
