To load an Xlet from another one

Question

Hi verybody.
I'm new about Xlets and mhp.
I've a problem: I want to load an xlet from a running one.
I've read about this in this forum, but the solutions I've found don't work on my project. Probably I mistake something.
I use the following classes:
Myremote:
public interface MyRemote extends java.rmi.Remote {
public void setValue (int a) throws java.rmi.RemoteException;
public int getValue () throws java.rmi.RemoteException;
} MyFilter:
import org.dvb.application.AppAttributes;
import org.dvb.application.AppID;
import org.dvb.application.AppsDatabase;
import org.dvb.application.AppsDatabaseFilter;
public class MyFilter extends AppsDatabaseFilter {
private String name;
public MyFilter (String name){
super();
this.name = name;
private MyFilter() {
public boolean accept(AppID appid) {
AppAttributes appAttributes = AppsDatabase.getAppsDatabase().getAppAttributes(appid);
if (appAttributes != null) {
String name = appAttributes.getName(); 
if(name.equals(this.name)) 
return true; 
return false; 
} In the running Xlet, in the KeyListner, I try to load XletIWantToLoad (that is in the same package of the running Xlet )using the following code:
filter = new MyFilter("XletIWantToLoad.class");
System.out.println("After Filter");
if(this.theDatabase != null){ 
System.out.println("theDatabase: "+theDatabase); 
attributes = theDatabase.getAppAttributes(filter);
System.out.println("Attributes");
if (this.attributes != null){
while(this.attributes.hasMoreElements()){
AppAttributes info;
AppProxy proxy; 
info = (AppAttributes)attributes.nextElement();
proxy = (AppProxy)theDatabase.getAppProxy(info.getIdentifier());
proxy.start(null); 
}So that:
The problem is that the filter remains null....
Please, may you answer me about this?
Tanx a lot anyway....
Bye

Hi verybody.
I have the same problem.
I'm using the following code in my running xlet
public void keyPressed(java.awt.event.KeyEvent keyEvent) {
switch (keyEvent.getKeyCode()) {
case KeyEvent.VK_1 : {
System.out.println("Premuto il tasto 1");
System.out.println("theDatabase: "+theDatabase);
AppsDatabase theDatabase;
AppProxy proxy;
theDatabase = AppsDatabase.getAppsDatabase();
System.out.println("DOPO theDatabase: "+theDatabase);
AppsDatabaseFilter filter;
filter = new CurrentServiceFilter();
Enumeration attributes;
attributes = theDatabase.getAppAttributes(filter);
while(attributes.hasMoreElements()) {
AppAttributes info;
info = (AppAttributes)attributes.nextElement();
System.out.println("info: "+info);
AppID id = info.getIdentifier();
System.out.println("Id: "+id);
proxy = (AppProxy)theDatabase.getAppProxy(id);
System.out.println("Proxy: "+proxy);
proxy.start();
} Thanks
