Passing parameters through red5-web.properties
In this second type of method, we consider passing val;ues through the red5-web.properties file, taking help of red5-web.xml.
Consider the same example as above with the setter function expecting value from outside. So we will store the value in red5-web.properties file first as shown below.
webapp.virtualHosts=localhost, 127.0.0.1, 192.168.1.2
webapp.database=mydb.sqlite
Next thing is to tell red5-web.xml to pull variable value from red5-web.properties. Notice below how the application’s handler bean is instructed to do so.

<!--

-->
<bean id="placeholderConfig" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="location" value="/WEB-INF/red5-web.properties" />
</bean>
<!--

<bean id="web.context" class="org.red5.server.Context"

<!--
Defines the web scopes
-->
<bean id="web.scope" class="org.red5.server.WebScope"
init-method="register">
<property name="server" ref="red5.server" />
<property name="parent" ref="global.scope" />
<property name="context" ref="web.context" />
<property name="handler" ref="web.handler" />
<property name="contextPath" value="${webapp.contextPath}" />
<property name="virtualHosts" value="${webapp.virtualHosts}" />
</bean>
<!--
Defines the web handler which acts as an applications endpoint
-->
<bean id="web.handler" class="org.red5.core.Application" singleton="true">
<property name="database" value="${webapp.database}"/>
</bean>
</beans>
This is how the red5-web.xml inserts data from red5-web.properties into the bean definition.
<property name="database" value="${webapp.database}"/>
</bean>
If you want to pass parameters into a Red5 service handler class of your own, then the method is similar. The service handler must have a bean definition in red5-web.xml and the property must be passed in as shown for the application bean.
<property name="propertyname" value="somevalue"/>
</bean>
Special note:
You can pass a reference to your application adapter into your service class by using the syntax shown below.
<property name="application" ref="web.handler"/>
</bean>
And to receive this value in your service class, you must have a setter function setup as shown below:
public void setApplication(Application app)
{
this.application = app;
}
