Hi,

I resolved this issues by below code.

<%

Blob blob= <fetch from DB>

int myblobLength = (int) blob.length();
byte[] myblobAsBytes = blob.getBytes(1, myblobLength);
String qrCodeDisplay = DatatypeConverter.printBase64Binary(myblobAsBytes);

%>

<div class="container text-center">
   <img class="img-responsive" src="data:image/jpg;base64, <%=qrCodeDisplay%>"/>

</div>

I am storing image as a blob in db. Now i need to disply that blob image in jsp.

I'm assuming that you know how to get the image out of the database, and which image format it is.

In order to provide a URL for it, I'm assuming that you have a portlet (that contains your JSP). In that portlet, use a <portlet:resourceURL>, parameterize it with (e.g.) the image's id. In the portlet's serveResource method, use that id to find the appropriate image, set the content type and stream the image to the browser (resourceResponse.getOutputStream()).

The liferay's way is to create service.xml and portal-model-hints.xml and may be ext-spring.xml as well.
