Ext 的实例演示。

楼主很热心 支持 支持
希望多发表文章 哈哈

感谢楼主的文章，使像我这样的初学者受益匪浅啊

是很好的东西。

没有搭建起来总是报这样的错：
734 [main] ERROR org.springframework.web.context.ContextLoader - Context initialization failed
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory' defined in ServletContext resource [/WEB-INF/springapp-servlet.xml]: Invocation of init method failed; nested exception is java.lang.NoSuchFieldError: tableNameBinding
Caused by:
java.lang.NoSuchFieldError: tableNameBinding

哪位高人说一下,如何在 NetBeans IDE 6.0 中使用 ext?

var Footer = new Ext.Panel({
border:false,
autoLoad: {url: 'template/Footer.html', callback: function(){}, scope: this}
});
Footer.render('Footer');

这个怎么加载不了页面？？总是加载中，我是做的静态页面

我都加了啊！

不同的原因产生相同的错误——在tomcat启动时console回馈看不到细节——需要看tomcat目录下的logs文件夹下的LOG。
例如：
C:\Program Files\Apache Software Foundation\Tomcat 5.0\logs
=============下面是由于jar版本不同引发的错误，只有通过log文件才能分析出来=========

2008-03-21 00:18:29 StandardContext[/test]Closing Spring root WebApplicationContext

这个问题,多半是由jar版本引起的。

楼主我按照你说的做了
tomcat/logs/的日志文件内容为
2008-04-06 21:32:03 StandardContext[/ExtTest]Initializing Spring root WebApplicationContext

控制台的内容是这个
