You need action (or servlet) that will read image from db and write image to
the output stream setting appropriate conent-type.
Than you do:

Stream it to the ServletOutputStream and return null from the action.

Then how can one have an Java-Object, let's say Person.java. Person has
a property called 'avatare' which can be get with "File getAvatar()".
Can i do something like  or so?

Btw- this isn't really good practice, is it? The example below seems
good for an Ajax request but i am not sure if i should store my images
as a blob.

Re: Displaying images from database.

[Thomas Joseph]

Hi Prerna,

Use the Action Class for the image display solely for image display. When the 
browser executes the   tag, it is 
basically giving a saparate request to your action class that generates the 
image.  Notice that the action class returns null, which means that the action 
class will render the response itself and will not forward to any JSP page.  
The remaining protions of your JSP will be generated by other Action Class 
forwards as usual.

Hope this helps to understand better.

Thanks and Regards,

  Hi David

  Thanks for a prompt response.

  But I also want to display other things on the jsp page besides the
  image.
  For e.g.

  My jsp page would have

  Company name, Address, Business Area and its logo with an EDIT button
  and when the user clicks on the EDIT button he can update Address
  information and save the changes made

  How can I achieve this?

  Hi All,




  My application saves the images in database as BLOB. I now want to
  display these images stored in my database. How can I do this in struts

Re: Displaying images from database.

[vijay venkataraman]

Say if all request for images will refer to the same action like 
image.do, then

So map this to a particular action.
Set the content type and write the image content to the ServletOutputStream
return null for ActionForward.

The snippet below should give you an idea.
Consider if resource.getResource() returns a byte[]  - (Some how you 
should be able to get a byte[] for the image stored in DB.)
If image is of type gif or jpg/jpeg - then you can do something like 
what is shown below.
  
   String imgType = gif or jpg/jpeg // for understanding.

   String contentType = "image/";
   if(imgType.equalsIgnoreCase("gif")){
   contentType+="gif";
   }else if(imgType.equalsIgnoreCase("jpg")){
   contentType+="jpeg";
   }else {
   contentType = "text/html";
   }
   response.setContentType(contentType);
   ServletOutputStream outStream = response.getOutputStream();
   outStream.write(resources.getResource());
   outStream.flush();
   return null;

RE: Displaying images from database.

[prerna.sawhney]

Hi David

Thanks for a prompt response.

But I also want to display other things on the jsp page besides the
image.
For e.g.

My jsp page would have

Company name, Address, Business Area and its logo with an EDIT button
and when the user clicks on the EDIT button he can update Address
information and save the changes made

How can I achieve this?

Thanks & Regards

It's not. It doesn't get much easier than us pointing you at the source
code.

There have been several threads regarding this topic, some recently. All
you need to do is write a servlet (my personal preference) or Action
that returns the image data and reference it using a plain HTML IMG tag
(or a Struts img tag if you need to).

http://www.informit.com/guides/content.asp?g=java&seqNum=166&rl=1


Pay particular attention to the HttpServlet implementation with regards
to setting the content type etc.

Re: Displaying Images from database using Struts tags

[Frank W. Zammetti]

You don't really need to upgrade to 1.2.6, all you need to do is take the
DownloadAction class (and the ResourceStreamInfo class IIRC) from 1.2.6
and use it.  There's nothing that I recall that would make it not work in
previos versions of Struts.

I have an app that downloads images from a database, and while I wrote a
separate servlet to do it because of some security setup I had to provide
for, the code is extremely similar to the DownloadAction... what your
trying to do is in no way unusual, and anyone that has done it will have
similar-looking code :)

RE: Displaying Images from database using Struts tags

[Braun, James F]

At the risk of getting murdered again for too many comments I'll offer
this recipe

J.

How to read an image from a db and display in an html page

Goal: Display an image that is stored in a database blob in a .jsp page

Synopsis: The blob is read into a byte array that is stored in the
ActionForm. The .jsp page uses a http://struts.apache.org/userGuide/struts-html.html#img

The code:

This reads the image in from the db

// rs is the ResultSet that is returned from the db query

try
{
  pictureStream = rs.getBinaryStream("picture");
  byte[] bytes = new byte[1024*1024]; // some maximum size

  int byteSize = pictureStream.read(bytes); // read in the bytes
  
  byte[] bytesX = new byte[byteSize]; // create a new array of
the proper size
  
  for(int i=0;i

Your example is using Struts 1.2.6.  Maybe I can upgrade, but I don't

I think you're thinking about this the wrong way round. Tags run on
the server to generate HTML content - so all the  tag does
is render the html markup of  - its then the browsers
job to download the image referenced in the "src" attribute.

So what you need is to specify a url in that src attribute which will
run something on the server to get your image from the database and
return the image's content as the response. You can do that with a
Struts action - retrieve the image, write it out as the response and
return "null" (rather than an action forward) - setting the
appropriate content stuff.

There is a "download action" which is designed to make this kind of
thing easier (Ithink it was introduced in Struts 1.2.4), details here:

Not that I know of, unless the tag API doc at
http://struts.apache.org/struts-doc-1.2.x/userGuide/struts-html.html#img
is wrong.

You can, however, use an action or a servlet to deliver the image data.

Re: Displaying Images from database using Struts tags

[Hubert Rabago]

You'd have to write an Action which reads the image from the DB and
writes it onto the servlet's output stream.  There was a thread just
yesterday which discussed how to do this.  You can set your image URL
to that action and provide it with enough parameters to find your
image in the DB.
