错误：包org.jboss.netty.channel.socket.nio不存在

Question

哪个JAR包含org.jboss.netty.channel.socket.nio？我是而不是使用maven或常春藤，只是蚂蚁（从netbeans）。

蚂蚁编译给出：

-do-compile: 
    [javac] Compiling 4 source files to /home/thufir/NetBeansProjects/EchoClient/build/classes 
    [javac] /home/thufir/NetBeansProjects/EchoClient/src/net/bounceme/dur/netty/client/ObjectEchoClient.java:3: error: package org.jboss.netty.channel.socket.nio does not exist 
    [javac] import org.jboss.netty.channel.socket.nio.NioClientSocketChannelFactory; 

在类路径是：

这是一个从下载：

http://netty.io/downloads.html

网状，4.0.21.Final.tar .bz2

我将该下载的每个JAR添加到项目中。是的，我意识到它没有使用CLI javac classpath，但JAR在项目中以及在上面的输出中都是可见的。

我翻看了一些JAR文件，无法找到这个特定的类。

您似乎在尝试使用netty 4.0构建针对netty 3.x开发的应用程序。已有API changes，包括频道创建和引导。此外，软件包前缀已从org.jboss.netty更改为反映项目状态更改的io.netty。

使用API documentation（不再记录NioClientSocketChannelFactory）与您正在使用的版本相对应，并检出提供的示例（netty-example-4.0.21.Final-sources.jar）以帮助移植您拥有的任何代码针对netty 3.x构建。
