Hi,
How should I read/display image from Database...which is stored interms of
bytes in the Database.
Please suggest me some way to render the image in JSP.
Custom servlet which retrieves data from DB, writes it to the output stream.
It should define correct headers first (mimeType, Expires, Date).
Map it to some url like
/images/*
and you may pass identifiers by composing URLs like
/images/myID.jpg

Hi kranti,
You have to use BLOB's to store images in the DB..
Get the Out Stream from the BLOB and then write the byte[] to it..

Yes you can initiate an attribute of type arrayList in the DynaForm as
follows,
form-property name=yourList type=java.util.List /
