import flex.messaging.messages.Message;
public class TestAdapter extends ServiceAdapter {
public Object invoke(Message message) {
MessageService msgService = (MessageService)service;
msgService.pushMessageToClients(message, true);
msgService.sendPushMessageFromPeer(message, true);
return null;

service can not resolved about MessageService msgService =
(MessageService)service;
please tell me a method :how to write this TestAdapter class.

Answer 1

ths, i can success.
but one error occur when i send message from java class to
lcds2.5 service.
i tranfer this IMessageUtil interface's setMessage method,set
param as "test",but no value in mxml file's mx:Consumer .
my message-config.xml is correct.
message-config.xml:
<adapter-definition id="fdschathandler" class="test"/>
<destination id="fdschat">
<properties>
<network>
<session-timeout>0</session-timeout>
</network>
<server>
<max-cache-size>1000</max-cache-size>
<message-time-to-live>0</message-time-to-live>
<durable>false</durable>
</server>
</properties>
<channels>
<channel ref="my-rtmp"/>
</channels>
<adapter ref="fdschathandler"/>
</destination>
java class:
package test;
import flex.messaging.MessageBroker;
import flex.messaging.MessageException;
import flex.messaging.messages.AsyncMessage;
import flex.messaging.messages.Message;
import flex.messaging.services.MessageService;
import flex.messaging.services.ServiceAdapter;
public class MessageUtil extends ServiceAdapter implements
IMessageUtil {
public Object invoke(Message message) {
try{
MessageBroker broker = MessageBroker.getMessageBroker(null);
MessageService msgService = (MessageService)
broker.getService("message-service");
msgService.pushMessageToClients(message, true);
msgService.sendPushMessageFromPeer(message, true);
return null;
}catch(MessageException ff){
System.out.println("fff:="+ff.getErrorMessage());
catch(Exception e){
e.printStackTrace();
return message;
public void setMessage(String mess) {
try{
AsyncMessage message=new AsyncMessage();
message.setDestination("fdschat");
message.setBody(mess);
this.invoke(message);
}catch(Exception e){
e.printStackTrace();
