Serialization, agents sending objects, possible?

Question

writing objects to a stream is mostly a straight forward task, but what happens if you don't have a stream to write to? This is a sample code from aglets, but it doesn't work any suggestions ? (Anyone know if I should use Jini instead?) :
// The class I want to transfer... How can I serialize this class properly?
public class TransferObject implements java.io.Serializable{
private String name;
private int age;
/** Creates a new instance of TransferObject */
public TransferObject(String name, int age) {
this.name = name;
this.age = age;
public String getName() {
return name;
public int getAge() {
return age;
// The mother aglet, that will create a child aglet
public class MotherAglet extends Aglet{   
public void run()
URL codebase;
try{           
codebase = new URL("atp://PC06");
     TransferObject tO = new TransferObject("This is transferobject", 1);
     // createing a ChildAglet , sending the tO refernce
getAgletContext().createAglet(codebase, "ChildAglet", tO);
}catch(Exception e) {
System.out.println(e.getMessage() + "Creation went wrong");
public class ChildAglet extends Aglet{
public void onCreation(Object init) {
TransferObject tO = null;
try{
tO = (TransferObject)init;
}catch(Exception e) {           
System.out.println(tO.getName());
If I had added the properties of TransferableObject reference in a Vector and re - initiated a new Object at ChildAglet this will work, but it would be easier to just transfer the object directly. Is there a way of doing this ?

I had a problem with this Aglet.
import com.ibm.aglet.*;
import com.ibm.aglet.util.*;
import com.ibm.agletx.util.SeqPlanItinerary;
import java.util.* ;
public class GatherInfo extends Aglet {
StringBuffer buffer;
SeqPlanItinerary itinerary;
public void onCreation(Object ini) {
itinerary = new SeqPlanItinerary(this);
itinerary.addPlan("atp://marcus:500/", "getLocalInfo");
itinerary.addPlan("atp://marcus:501/", "getLocalInfo");
// return to host and print result
itinerary.addPlan(getAgletContext().getHostingURL().toString(),"pr
intResult");
this.start() ;
public boolean handleMessage(Message msg) {
if (msg.sameKind("getLocalInfo")) {
getLocalInfo(msg);
return true;
} else if (msg.sameKind("printResult")) {
System.out.println(buffer);
return true;
return false;
public void run() {
System.out.println("Hello, just visiting...") ;
public void oncemore() {
try {
itinerary.startTrip();
} catch (Exception ex) {
ex.printStackTrace();
public void start() {
buffer = new StringBuffer();
oncemore();
public void getLocalInfo(Message msg) {
AgletContext ac = getAgletContext();
setText("Here I am about to gather info, and waiting ...") ;
// waitMessage(2 * 1000);
buffer.append("I've been to " + ac.getHostingURL().toString() +
"\n") ;
buffer.append(new LocalInfo().getAll()) ;
buffer.append("\n") ;
When execute this code show me the next error
java.io.exception: FileNotFound c:\aglets-2.02\public\[Ljava\lang\objec; .class
I need help, what is this?
