Hi Wendy Smoak,

These are the steps:

In Http Client side:

byte[] decodeSevletData =3D
org.apache.commons.codec.binary.Base64.decodeBase64(authpost.getResponse
Body());

Vector servletVecoter =3D (Vector)
SerializationUtils.deserialize(decodeSevletData);
                                                          =20
for (int i =3D 0; i < servletVecoter.size(); i++) {
CommunicationVO vo =3D (CommunicationVO) servletVecoter.get(i);
System.out.println("id :" + vo.getSubmissionId() + ": desc:" +
vo.getDescription());}


In servlet side:


com.parago.communication.CommunicationVO commVO1 =3D new
com.parago.communication.CommunicationVO(45, "Object1");
            com.parago.communication.CommunicationVO commVO2 =3D new
com.parago.communication.CommunicationVO(75, "Object2");
            Vector commVOVector =3D new Vector();
            commVOVector.add(commVO1);
            commVOVector.add(commVO2);

byte[] encodedData =3D
Base64.encodeBase64(SerializationUtils.serialize(commVOVector));
//           String encodedString =3D new String(encodedData);

OutputStream os response.getOutputStream();
Os.write(encodedData);
os.flush();
os.close();
return;

Please tell me where I can improve this code as its not working.
Thanks.
Sanjeev Tripathi

Can you list the steps you're taking, and post the code that is not
working?

I _think_ you're stuck on sending a base 64 encoded serialized object
back
to the client, but I'm not certain.  If that's the case, please show the
server-side code you're using to send the response, and then what you've
done on the client.
