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

Question

哪个JAR包含org.jboss.netty.channel.socket.nio

我是，不是使用Maven或Ivy的，而是Ant。

Ant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;

在类路径中有：

这个库是netty-4.0.21.Final.tar.bz2，它是从官方的Netty 网站下载的。

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类路径，但是JAR在项目中以及上面的输出中都是可见的。

我翻阅了一些JAR，却找不到这个特定的类。

您似乎正在尝试使用Netty4.0构建一个针对Netty3.x开发的应用程序。

已经出现了API变化，包括信道创建和引导。此外，包前缀从org.jboss.netty更改为io.netty，反映了项目状态的变化。

使用与您正在使用的版本相对应的API文档 (不再记录NioClientSocketChannelFactory)，并签出所提供的示例( Netty -示例-4.0.21.final-Soures.jar)，以帮助移植针对Netty3.x构建的任何代码。
