这里有新鲜出炉的精品教程，程序狗速度看过来！

ExtJS Javascript库

ExtJS是一种主要用于创建前端用户界面，是一个基本与后台技术无关的前端ajax框架。

基础夯实一点，会有好处的，排错的时候就体现出来了,下面就Ext.Direct做一些排错笔记与大家一一分享，感兴趣的朋友可以参考下哈
偶泪滴嘎嘎，终于，终于完成了一部分ExtJS。
（基础夯实一点，会有好处的，排错的时候就体现出来了）
下面就Ext.Direct做一些排错笔记：

错误一： 
 
严重: StandardWrapper.Throwable 
java.lang.ArrayIndexOutOfBoundsException: 1

这是为什么呢？
答案：
@DirectFormPostMethod
这个不对，这个产生了上面的错误，改成： @DirectMethod
同时删掉，由@DirectFormPostMethod生成的输出： 
 
import com.softwarementors.extjs.djn.config.annotations.DirectFormPostMethod;

错误二： 
 
ERROR: com.softwarementors.extjs.djn.router.processor.standard.json.JsonRequestProcessor - "(Controlled) server error: 1 for Method 'FormAction.submitData'" (rid=1000)

控制层出错，也就是逻辑上不对，我的函数里面要求传入的参数，和提交的参数不对，
放心，不是xml配置问题，是传入的参数问题。所以重点在参数上，也就是语法。

我的错误原因：
Java要求传入的参数为两个： 
 
public Info submitData(String name,String password)

而我在ExtJS 中实际传入的参数是一个： 
 
var params= username.getValue()+Password.getValue(); 
FormAction.submitData(params,function(result,e){}

改写一下就行了： 
 
FormAction.submitData(username.getValue(),Password.getValue(),function(result,e){}

错误三：

原因是里面没有这个类：
com.softwarementors.extjs.djn.test.config.GsonBuilderConfiguratorForTesting
这个错误在web.xml里面，把它们删了就行了： 
 
<init-param> 
<param-name>registryConfiguratorClass</param-name> 
<param-value>com.softwarementors.extjs.djn.test.servlet.config.RegistryConfiguratorForTesting</param-value> </init-param> 
<init-param> 
<param-name>gsonBuilderConfiguratorClass</param-name> 
<param-value>com.softwarementors.extjs.djn.test.config.GsonBuilderConfiguratorForTesting</param-value></init-param>

大概就这三个，我的情况就是这样。
