Wendy,
Here is complete code:
http client side code
package com.parago.communication;
import org.apache.commons.codec.binary.Base64;
import org.apache.commons.httpclient.HttpClient;
import org.apache.commons.httpclient.NameValuePair;
import org.apache.commons.httpclient.methods.PostMethod;

import java.util.Vector;
public class FormLogin {
// static final String LOGON_SITE = "developer.java.sun.com";
static final String LOGON_SITE = "localhost";
static final int LOGON_PORT = 8080;
public FormLogin() {
super();
}
public static void main(String[] args) throws Exception {
PostMethod authpost = null;
try {
HttpClient client = new HttpClient();
client.getHostConfiguration().setHost(LOGON_SITE,
LOGON_PORT, "http");
com.parago.communication.CommunicationVO commVO1 = new
com.parago.communication.CommunicationVO(145, "Object1");
com.parago.communication.CommunicationVO commVO2 = new
com.parago.communication.CommunicationVO(175, "Object2");
Vector commVOVector = new Vector();
commVOVector.add(commVO1);
commVOVector.add(commVO2);
byte[] encodedData =
Base64.encodeBase64(SerializationUtils.serialize(commVOVector));
String encodedString = new String(encodedData);
System.out.println("Encoded Legnth: " + encodedData.length +
"Encoded String Legnth: " + encodedString.length());
encodedData = encodedString.getBytes();
byte[] decodeData = Base64.decodeBase64(encodedData);
Vector processedVOVector = (Vector)
SerializationUtils.deserialize(decodeData);
for (int i = 0; i < processedVOVector.size(); i++) {
CommunicationVO vo = (CommunicationVO)
processedVOVector.get(i);
System.out.println("id :" + vo.getSubmissionId() + ":
desc:" + vo.getDescription());
}
authpost = new PostMethod("/argo/ArgoControl");
// Prepare login parameters
NameValuePair action = new NameValuePair("action", "login");
NameValuePair url = new NameValuePair("url",
"argo/index.html");
NameValuePair userid = new NameValuePair("LOGIN_NAME",
"smith");
NameValuePair password = new NameValuePair("LOGIN_PASSWORD",
"irving");
NameValuePair thickClient = new NameValuePair("ThickClient",
"ThickClient");
NameValuePair commVOParm = new NameValuePair("CommVO",
encodedString);
// Set parameters
authpost.setRequestBody(new NameValuePair[]{action, url,
userid, password, thickClient, commVOParm});
//Execute method
client.executeMethod(authpost);
System.out.println("Login form post: " +
authpost.getStatusLine());
System.out.println("Response content-type: " +
authpost.getResponseCharSet());
byte[] decodeSevletData =
org.apache.commons.codec.binary.Base64.decodeBase64(authpost.getResponse
BodyAsString().getBytes());
Vector servletVecoter = (Vector)
SerializationUtils.deserialize(decodeSevletData);
System.out.println("processedVOVector :" + servletVecoter);
for (int i = 0; i < servletVecoter.size(); i++) {
CommunicationVO vo = (CommunicationVO)
servletVecoter.get(i);
System.out.println("id :" + vo.getSubmissionId() + ":
desc:" + vo.getDescription());
}
} catch (Exception e) {
e.printStackTrace();
} finally {
// Release the connection.
System.out.println("Releasing connection: ");
authpost.releaseConnection();
}
}
}
servlet code in service method
if
(ThickClient.equalsIgnoreCase(request.getParameter("THICK_CLIENT_FLAG"))
)
{
ServletOutputStream oos =
response.getOutputStream();
com.parago.communication.CommunicationVO commVO1 =
new com.parago.communication.CommunicationVO(45, "Object1");
com.parago.communication.CommunicationVO commVO2 =
new com.parago.communication.CommunicationVO(75, "Object2");
Vector commVOVector = new Vector();
commVOVector.add(commVO1);
commVOVector.add(commVO2);
byte[] encodedData =
Base64.encodeBase64(SerializationUtils.serialize(commVOVector));
oos.print(new String(encodedData));
oos.flush();
oos.close();
return;
}
value object that I am passing
package com.parago.communication;
/**

*/
public class CommunicationVO implements java.io.Serializable{
public CommunicationVO(int id,String desc) {
this.submissionId = id;
this.description = desc;
}
private int submissionId;
private String description;
public int getSubmissionId () {
return submissionId;
}
public String getDescription() {
return description;
}
}
I am getting following exception
java.io.StreamCorruptedException: invalid stream header
I tried sending byte[] also instead of string but I am getting same
error.
thanks.

Have you been able to fix the problem yet? I *might* have time to look
at
it this weekend. A more complete example would help, along with a
description of exactly what you wanted, and what your code is doing
instead.
( http://www.catb.org/~esr/faqs/smart-questions.html ) Maybe try it
with a
Vector of String or Date objects, so that anyone who wants to try your
code
can do it without needing additional classes.
