Version 1.1.111 (2009-04-10)Google App Engineで、DBにはGoogle App Engine Datastoreを使わないといけなかった(?)んだけど、JavaサポートのおかげでRDBのH2(in-memory)も使えるようになっていたみたい。
* In-memory databases can now run inside the Google App Engine.

Sending a message from ActionScript:Merapiを使って、AIRからレゴマインドストームロボット(Lego Mindstorm Robot)を操作してる！？
var message : Message = new Message();
message.data = "Hello from Merapi Flex.";
message.type = "Reply";
Bridge.instance.sendMessage( message );
Sending a message from Java:
Bridge bridge = Bridge.getInstance();
Message message = new Message();
message.setData("Hello from Merapi Java.");
bridge.sendMessage(message);
Receiving a message in Flex:
<merapi:BridgeInstance
id="bridge" result="handleResult(event)" />
<mx:Script>
<![CDATA[
private function handleResult( event : ResultEvent ) : void
{
var message : IMessage = event.result as IMessage;
Receiving a message in Java:
Bridge.getInstance().registerMessageHandler("Reply", messageHandlerInstance );
public void handleMessage( IMessage message )
{
System.out.println( message.getData() );
}
package net.air_life.guice_blazeds.service;次にBlazeDSで使用するFactoryを作るために、guice-blazedsが提供してくれてるAbstractGuiceFactoryのサブクラスを定義。
public class HelloWorldService {
public String sayHello() {
return "Hello World.";
}
}
package net.air_life.guice_blazeds.factory;あとはBlazeDS側の設定services-config.xmlに上記のFactoryを追加。
import uk.co.chasetechnology.guice_blazeds.AbstractGuiceFactory;
import com.google.inject.Guice;
import com.google.inject.Injector;
public class GuiceFactory extends AbstractGuiceFactory {
private Injector injector;
public GuiceFactory() {
injector = Guice.createInjector();
}
public <T> T createInjectedObject(Class<T> clazz) {
return injector.getInstance(clazz);
}
}
<services-config>最後にremoting-config.xmlにHelloWorldServiceを追加。
....
<factories>
<factory id="guice" class="net.air_life.guice_blazeds.factory.GuiceFactory"/>
</factories>
</services-config>
あとはクライアント側からhelloWorld宛にサービス呼び出しをかけると、HelloWorldという文字列を受け取れます。
....
<destination id="helloWorld">
<properties>
<source>net.air_life.guice_blazeds.service.HelloWorldService</source>
<factory>guice</factory>
</properties>
</destination>

The Proxy server can now record binary requests. By default the content types application/x-amf and application/x-java-serialized-object will be treated as binary and saved in a file. To change the content types, update the property proxy.binary.types .
