How to display a Blob object retreived from database

[Patrick Yip <yi...@ICG.com>]

I can display images correctly using IAsset such as this
 
Html:
<img jwcid="@Image" alt="ognl:manufacturerName"
image="ognl:logoLinkAsset" border="1"/>
 
 
class:
 
public IAsset getLogoLinkAsset(){
   ...
  logoLink  = "/images/sony.gif" ; 
 
  return (IAsset) new ExternalAsset(logoLink,null);
 
}
 
 
Question, if have a Blob object retrieved from a database, how do I
display the image now?
 
Any suggestion is greatly appreciated.

	You'll need to create a special servlet to serve the blobs. Then
embed a link to that servlet into the HTTP e.g.

	<img src="/myhost/myaPP/imageServlet?imagename=foo" />

	There's no way to "inline" binary data into an HTTP page.
