Aashish,
You must design your EJB to avoid to load all the images
data in the AS memory.
To do that you can create a RemoteIterator which stream
data on a chunks-per-chunk basis from the database
to the EJB and then to the client.
The Remote Iterator is a stateful (it use a JDBC Statement)
Session EJB which provides the following methods:
package com.xxx.ejb;
import java.util.*;
import javax.ejb.*;
import java.rmi.*;
public interface EjbIterator extends EJBObject {
Chunk next() throws Exception;
boolean hasNext() throws Exception;
}
Chunk contains a chunk of data, such as 1024 bytes, or whatever you want.
Another solution should be to use a RMI or RMI/IIOP (probably fatser)
server to manage the downloads outside of the EJB container.
Hope this help
