Retrieve image from database to non-database item

Hello
I need to load in a non database item, a image stored in a long raw field in the database.
The READ_IMAGE_FILE works fine to read from a file and to save the image in the database, but how I load the image in a block in a non database item?
Any suggestions???
Thanks!!!

Hi, thanks for your comments...
I need to display in non-db-items because I have a form that dynamically fills an matrix of items from various tables. For example one data is on the table A, another data in table B and image is stored in the table C.
A process dynamically obtains each data where needed and fill the matrix based in a previous criteria.
Possibly this management can be adapted so that the image is read into db-items in my form, however I would like to know if there is a simpler way to do that, without having to change my code.
Thanks!

JAVA, sqlserver - Need to load an image from the sql server database

hi,
I need to load an image from the sql server database using java. I have connected to the database and getting all other records except the records for a photo (datatype = LONGVARBINARY) and Remarks (datatype = LONGVARCHAR).
I am using java and sql server db. The photo and remarks are stored in the db. and i need to show the image and the remarks fetching them from there.
I get the error :
Thread-9 org.hibernate.MappingException: No Dialect mapping for JDBC type: -1
How can I achieve this?
Thanks,
Gargi

Exactly. And are you using MySQL?
No. You are using Microsoft SQL server if I have to believe your initial post. A quick google tells me that the dialect class to use is:
org.hibernate.dialect.SQLServerDialect

Question on retrieve image from mysql

i want to retrieve image from mysql database and display on GUI
can anyone tell me how to do
Thank you

You can use the JDBC API for Java Database Connectivity. With this you can obtain data from the database using Java. There is an excellent tutorial here at Sun.com: http://www.google.com/search?q=jdbc+tutorial+site:sun.com You can get the MySQL JDBC driver at their own site: http://www.google.com/search?q=download+jdbc+driver+site:mysql.com Get the most recent version which suits your environment. There is also good documentation available over there.
For displaying in the UI, the approach differs per UI. As you didn't mention which UI you are using, I can't help you further in detail.

Retrieving image from database in form 6i

hello all
i'm working on form 6i...
i have uploded images into the database of customers in my application using READ_IMAGE_FILE.. IT IS FINE...
But when i am trying retrieves records into the form.... i'm getting all the data except image... Image field is showing empty..
How can i get image from database to form
can u plz help me.....
thanks

What data type you used for storing image in database. If it is long raw, then you can place an image item within your data block on form and associate it with the column name. This should populate the image by itself.
Below para is from Forms Help.
Image items can be populated in the following ways:
+1. a fetch from a LONG RAW database column+
An image item in a data block is populated automatically when the end user or the application executes a query in the block. When a fetched image is modified or replaced, Form Builder marks that record as Changed, and the next commit operation saves the new image to the corresponding LONG RAW column in the database.
Note: You cannot write a SELECT statement to select a LONG RAW value INTO an image item.
+2. executing the READ_IMAGE_FILE built-in to read an image from the file system+
+(To dynamically write an image from an image item out to a file, use the built-in procedure WRITE_IMAGE_FILE.)+

If I select DEMO_BLOB and BLOBCOL from servers window, I can see in properties window:

If I select IMAGE column from mysql-table and I can see in properties window this:

Could this SQL Type difference be the reason why I can't get images from mysql to the page?

Retrieve images from DB and attach them to email through javamail

Hi,
I'm trying to use javamail to send emails containing text and images (HTML mail), if I use a physical file in my computer as the image source and use FileDataSource everything works just fine. The problem is that the images in my app are stored into a DB (I'm using MySQL, java struts & DAO), so in order to retrieve & display them I use a jsp that returns a byte array as shown in the example bellow
<img src='getImage.jsp?itemId=<bean:write name="item" property="itemId"/>&heigth=180&width=140&imageIndex=1'/>getImage.jsp reads the image from the DB for the specified item and returns an image of size "heigth*witdh", this works fine when invoked from any jsp or java action class, but I can't get it to work to insert an image into an email as attachment
I've tried to use ByteArrayDataSource and the mail is sent correctly and can be read but the image won't show
bds = new ByteArrayDataSource("/getImage.jsp?itemId="+itemId+"&heigth=180&width=140&imageIndex=1", "image/jpeg");
imageMime.setDataHandler(new DataHandler(bds));
imageMime.setHeader("Content-ID", "<\" + itemId + \">"); // backslashes aren't there in the real code, but if I remove them '+ itemId +' won't show
mailParts.addBodyPart(imageMime);I've also tried with URLDataSource but can't get it to work either, can somebody plz point me in the right direction?
thanks in advance
Edited by: informacionCubica on Jun 8, 2009 3:46 PM

Hello bshannon,
Thanks for your answer, I tried your suggestion but when I use URLDataSource I get the error message http 500 (in my original post I said that using URLDataSource the mail was sent but without the image... my mistake, I was getting this same error). I traced the error and I found that it is caused by a null pointer exception... let me explain
This is the code for the jsp that returns the image:
4        <jsp:useBean id="coverImage" class="com.mqm.struts.getImageAction" scope="session" />
5       <%
6           // Desired size of the image to return
7           int heigth = Integer.parseInt(request.getParameter("heigth"));
8          int width = Integer.parseInt(request.getParameter("width"));
9
10          // Each item can have up to 6 images (ordered by id), this indicates wich of one we have to return
11            int imageIndex = Integer.parseInt(request.getParameter("imageIndex"));
12        byte[] imgData = coverImage.getItemImageAction(request.getParameter("itemId"), request,heigth, width, imageIndex );
13        response.setContentType("image/jpeg");
14        OutputStream o = response.getOutputStream();
15         o.write(imgData);
16         o.flush();
17         out.clearBuffer();
18         o.close();
        %> getImageAction is my DAO class that actually reads the image data from the DB, when I use this 'getImage.jsp' inside any other jsp in the app it works, but when used as described in the first post the request parameter in the line 12 doesn't have the session info, apparently creates a new session or something and since I use information in the session to create the DAO factory I can't connect to the DB and get this error..
pls tell me if I explained my self or I'm just talking non sense
regards

I think I am happy with the Mysql, and I have read the various arguments about storing images in mysql but for my purpose I wanted to store the image in the database.

I have a .php file which is merging these to tables correctly but the image is displayed as

Hi Murray
You must despair with beginers like me, attachments showed as having been
sent so lets try again.
I have been able to find a tutorial that works well all the way through, I
can even see the images in the browser!! but only shows images individually
on a page.
http://www.phpriot.com/articles/storing-images-in-mysql/7
However, what I want to do is to have a page that links my images table and
another table, all of which I have set up and is working other then showing
the images. All was very straight forward until sorting out the image. If
I can work out what to take from the above tutorial that works into my page,
I am sure all will be fab.
Storing them in the mysql was my preferred method as there are not alot and
they can be low resolution and I thought it would be fairly straight
forward!! however finding out that I am having to adapt code as dreamweaver
doesn't support the blob attribute is getting me out of my knowledge.
All the best
Gilly

               out.println(imgLen.length());Your JSP was supposed to write an image to the output and you wrote some irrelevant strings to the output before? This will corrupt the image. It's like opening the image in a text editor and adding some characters before to it.
               byte [] rb = new byte[len];Memory hogging. Don't do that.
          out.println(ee);You should be throwing exceptions and at least printing its trace, not sending its toString() to the output.
You may find this article useful to get an idea how this kind of stuff ought to work: [http://balusc.blogspot.com/2007/04/imageservlet.html].

How to retrieve image from a document

Hi
I am a beginner to Adobe InDesign SDK (CS4) and was needing some help. Here is the sceneario
I have a simple InDesign document with an image in it. I am trying to retrieve the image and do some proprietory actions on it.
I am wondering if there is an InDesign API which can retrieve image on a document. What is the return value from such an API. (e.g does the API return a pointer to the image object or maybe location of the image on the filesystem ? ). What I am trying to do is once I can get a "handle" to the returned image, I would like to manipulate it and save it in a proprietory format.
Any pointers on this would be highly appreciated
thanks!
Sam

Hi,
You can get the path of the linked image file and then you can manipulate this image.
I think ILinkUtils and ILink will certainly help.
You can also check (for better understanding) CHM->PortingGuide->Links Archtecture.
Thanks.
