解决方案

出现上述异常的原因：Spring在查找XML schema namespace [http://www.directwebremoting.org/schema/spring-dwr] 对应的NamespaceHandler时，找不到。在Spring中报错的位置如下：public BeanDefinition parseCustomElement(Element ele, BeanDefinition containingBd) {String namespaceUri = ele.getNamespaceURI();NamespaceHandler handler = this.readerContext.getNamespaceHandlerResolver().resolve(namespaceUri);if (handler == null) {[b]error("Unable to locate Spring NamespaceHandler for XML schema namespace [" + namespaceUri + "]", ele);[/b]return null;}return handler.parse(ele, new ParserContext(this.readerContext, this, containingBd));}代码中加粗的地方为异常信息。XML schema namespace与NamespaceHandler的对应关系存放在Spring jar包下META-INF/spirng.handlers文件中，查看下你的spring jar 包是否有对应的关系
解决方案二：
换个dwr.jar，换为dwr-2.0.2.jar就行了

AJAX实践DWR篇

ajax DWR(Direct Web Remoting)是一个WEB远程调用框架.利用这个框架可以让AJAX开发变得很简单.利用DWR可以在客户端利用JavaScript直接调用服务端的Java方法并返回值给JavaScript就好像直接本地客户端调用一样(DWR根据Java类来动态生成JavaScrip代码).它的最新版本DWR0.6添加许多特性如:支持Dom Trees的自动配置,支持Spring(JavaScript远程调用spring bean),更好浏览器支持,还支持一个可选的com

AJAX?框架DWR?2.0?M1?发布

ajax AJAX 框架DWR近日宣布,发布DWR 2.0 M1 2.0 M1 新版本. DWR(Direct Web Remoting) 项目是在Apache许可下的一个开源的解决方案,它供给那些想要以一种简单的方式使用AJAX和XMLHttpRequest的开发者.它具有一套Javascript功能集,它们把从HTML页面调用应用服务器上的Java对象的方法简化了.它操控不同类型的参数,并同时保持了HTML代码的可读性.DWR不是对一个设计的插入,也不强迫对象使用任何种类的继承结构.它和se

菜鸟调错（四） Spring与DWR集成，配置文件报错

背景简介: 该项目是市信用办的一个系统,之前好像是一个石家庄的公司负责的.我属于是半路接手.拿到源码后,根据他们给的简(shao)单(de)明(ke)了(lian)的说明把项目搭起来.结果可想而知,项目文件一片红.于是就开始解决这些错误,好在很多错误都是类似的.经过一番捣鼓,大部分的错误都解决了,有一个Spring跟DWR集成配置的错误,错误信息如下: Multiple annotations found at this line: - schema_reference.4: Failed to
