Red5 + flex Application Development

Red5 applications are divided into two parts: server and client. Eclipse is used as the development environment, and Flash builder4.6 is used for client flex development. Note that red5 only supports jdk1.6. The following is a simple red5 application to implement communication between the client and the server.

1. Server

Set the eclipse workspace to D: \ Program Files \ red5 \ webapps and create a Java project named "hellored5.

In properties-> JAVA build path-> libraries-> Add external jars..., add the dependency library red5. jar, which is in the red5 installation directory.

Set the compile output directory to hellored5/WEB-INF/classes.

Copy the DOC/template/MyApp/WEB-INF directory to the project directory.

After completing the preceding steps, the project directory structure is as follows:

Add a Java class named hellored5, which is simple and inherited from applicationadapter.

Hellored5.java

package sample;import org.red5.server.adapter.ApplicationAdapter;public class HelloRed5 extends ApplicationAdapter {public String sayHello() {return "Hello, red5!";}}
Modify several configuration files below
Red5-web.properties
webapp.contextPath=/helloRed5webapp.virtualHosts=localhost, 127.0.0.1
Web. xml
...<context-param><param-name>webAppRootKey</param-name><param-value>/helloRed5</param-value></context-param>...
Red5-web.xml,
<bean id="web.handler"     class="sample.HelloRed5" singleton="true" />
Now all the work on the server is done.
2. Client
Use flash builer4.6 to create a flex project named "hellored5client" and use netconnection to communicate with the server. The function of the client is very simple. A button and a lable control are placed on the interface. After clicking the button, the string "Hello, red5!" obtained from the server is displayed! ".
Hellored5client. mxml

Note:
nc.client = this;public function onBWDone():void{}
No. Otherwise, the following error is prompted.
Error #2044: unprocessed asyncerrorevent :. TEXT = Error #2095: flash.net. netconnection cannot call the onbwdone callback. Error = referenceerror: Error #1069: The onbwdone attribute cannot be found on hellored5client, and no default value exists.
3. Run
Start red5 and open the compiled hellored5client.html file on the browser, and click "Say hello". The result is as follows:
