Red5应用程序调试

Question

i'm trying to deploy my red5 app to the webapps folder. But! I've got some errors in my output.

    Exception in thread "Launcher:/myApp" org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'web.context' defined in ServletContext resource [/WEB-INF/red5-web.xml]: Unsatisfied dependency expressed through bean property 'clientRegistry': : Cannot find class [org.red5.core.Application] for bean with name 'web.handler' defined in ServletContext resource [/WEB-INF/red5-web.xml]; nested exception is java.lang.ClassNotFoundException: org.red5.core.Application; nested exception is org.springframework.beans.factory.CannotLoadBeanClassException: Cannot find class [org.red5.core.Application] for bean with name 'web.handler' defined in ServletContext resource [/WEB-INF/red5-web.xml]; nested exception is java.lang.ClassNotFoundException: org.red5.core.Application

After all of that i've got my app folder in webapps, but there is no .class file in the classes folder of my project. So, i can't use server-side app in my client app. What's wrong?

App was built by default. Here is my red5-web.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">
<beans>

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

    <!--
    Defines the web context
    -->
    <bean id="web.context" class="org.red5.server.Context" 
        autowire="byType" />

    <!--
    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" />

</beans>

And my Application class

package org.red5.core;

import org.red5.server.api.IConnection;
import org.red5.server.api.IScope;
import org.red5.server.api.service.ServiceUtils;

/**

public class Application extends ApplicationAdapter {

    /** {@inheritDoc} */
    @Override
    public boolean connect(IConnection conn, IScope scope, Object[] params) {
        return true;
    }

    /** {@inheritDoc} */
    @Override
    public void disconnect(IConnection conn, IScope scope) {
        super.disconnect(conn, scope);
    }

}

I did all of that with Red5 plugin in Eclipse. So... i have no idea what could be wrong..

Answer 1

I had the exact same problem. Sounds like you're trying to follow the tutorial videos only using the new Red5_1.0, Like I was. After many days, beers, and bruises from banging my head against my desk, I discovered that if you change your class to "org.red5.server.scope.WebScope" in your red5-web.xml file it should work correctly (bean id="web.scope"). Also, you may need to change your org.red5.core source imports from "import org.red5.server.api.IScope;" to "import org.red5.server.api.scope.IScope;". Apparently there has been some class refactoring in the newer versions of Red5

Answer 2

I was getting a similar error, although when I checked my class was already set to "org.red5.server.scope.WebScope" as mentioned in Ninth Realm Matt's answer. I later found that I was missing the lib directory under webaps/chat/WEB-INF/.

This may be useful if anyone else has a similar problem.
