how to display an image stored in database?

2005-10-19 02:37

Hi all. How can i display an image, which is a field in our database, inside iReport. Currently the field has a datatype of 'image' and when I put it inside iReport and preview it, all i can see are the numbers representing that image. When we do this in Crystal we can see the actual image when we insert the field. Am i missing something here? Thanks for any help you can give...

Hi,

 

One way would be to call an external java class that streams the field content to a tempory file and returns that file name and path. Just instantiate your object in the section where you have placed the $F{xxx} field.

 

Cheers

We do load all needed images from DB before calling the fill-method and work with parameter where each image is an parameter of type "java.awt.Image" ... so no files just objects.... but I guess you want to see your image in designer already.. but AFAIK this isn't possible yet.

 

sorry

If you can see the numbers, it sounds like your image is a java.lang.String class. Try changing it to java.io.InputStream.
