中的配置
  <servlet>
    <servlet-name>dwr-invoker</servlet-name>
    <servlet-class>org.directwebremoting.servlet.DwrServlet</servlet-class>
    <init-param>

  <servlet-mapping>
    <servlet-name>dwr-invoker</servlet-name>
    <url-pattern>/dwr/*</url-pattern>
  </servlet-mapping>
[/code]
dwr中的配置
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE dwr PUBLIC "-//GetAhead Limited//DTD Direct Web Remoting 2.0//EN" "http://getahead.org/dwr/dwr20.dtd"><dwr>
  <allow>
    <create creator="spring" javascript="aclManager">
      <param name="beanName" value="aclManager"/>
    </create>
  </allow>
</dwr>
spring中的配置
</bean>
<bean id="aclManager" class="com.bjsxt.oa.manager.impl.ACLManagerImpl">
<property name="sessionFactory" ref="sessionFactory"/>
</bean>用aclManager中的方法进行存储出现异常

Answer 2

我最近也在学习dwr.但看了你的
dwr.xml中的配置
<create creator="spring" javascript="JUserBiz">
  <param name="beanName" value="userBiz" />
  <param name="location" value="applicationContext.xml" /><!-- 这句你好像没有加-->
  <include method="*" /> <!-- 默认也是匹配所有公开的方法-->
</create>
function addOrUpdatePermission(field){
    aclManager.addOrUpdate(
        "${aclForm.principalType}",
        ${aclForm.principalSn},
        field.resourceSn,
        field.permission,
        field.checked
    );
}
这里js调用,这么又有el表达式了呢,还有,加个回调函数看看...

Answer 3

好像是 spring的配置文件applicationContext.xml没有加载,
需要在程序中配置以下

在问一个问题
为何onload（）javascript在页面中不能自动运行啊？
