ARN No appenders could be found for logger (org.springframework.web.context.ContextLoader).
很显然你web没有配置springContextLoader或者spring的监听器
具体怎么配置 google一下就可以了
web.xml 上是这样配的.
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

log4相关jar加了没
properties文件有没有加！
之前用 tomcat5.5 的时候加了. 现在换成6.0 还没加. 我试试看
dwr.xml 没有了直接用 spring 来控制了.
<dwr:configuration>
        <dwr:convert type="bean" class="com.rango.project.service.*"></dwr:convert>
        <dwr:convert type="bean" class="com.rango.project.entity.*"></dwr:convert>
    </dwr:configuration>    <bean id="oneService"
        class="com.rango.project.service.OneService">
        <property name="tblOneDao" ref="tblOneDao"></property>
        <dwr:remote javascript="oneService" />
    </bean>
写在这里面了
我勒个擦擦滴. 昨晚弄到今天下午.终于弄好了. 知道什么原因了.
原来是我的 dwr3.0 的问题换成2.0的它就好了.
这这..它也太坑人了吧..把我可折腾的.. 我要发泄.. 不过还是谢谢大家.
liuyuhua0066 一说到dwr 给了我灵感结贴咯
