遇到的ExtJsbug,留个笔记

JDK 1.6 写Webservice时，runtime modeler error: Wrapper class com.ws.jaxws.DoSomething is not found问题的解决办法
1、问题如下：
Exception in thread "main" com.sun.xml.internal.ws.model.RuntimeModelerException: runtime modeler error: Wrapper class com.ws.jaxws.DoSomething is not found. Have you run APT to generate them?

2、解决办法（2选一，推荐办法2）：
1> 先用apt命令将主程序进行编译，然后生成一些java文件
2> 升级JDK到版本jdk1.6u17或以后

3、ExtJs
extjs中出现错误：
1.this.addevents is not a function错误:
解析：有一个原因是由于其中的一个控件没有使用关键字new出来或使用关键字new来创建时出错
2.this.proxy is undefined
解析：
检查mode是否设置错误，mode默认是remote，是从远程服务器加载。如果从本地加载，应该设置mode为local。
