ssh + dwr 不知道是bug还是什么问题啊
配置文件如下:

dwr.xml
<dwr>

</param>
<include method= "validateName "> </include>
<param name= "location " value= "applicationContext.xml "> </param>
</create>

</dwr>
注:如果把creator改成new 和param name 改成class程序就没有问题了
jsp 页面

alert(name);
springUser.validateName(name);

dwr 调用的java类
public class DynamicCheck {
public String validateName(String name){
String error= "jjjjjjjjjjjjj ";
return error;
}
}
spring 配置文件
<bean id= "dynamicCheck " class= "com.dwr.DynamicCheck " > </bean>
用了spring 就不行了老是在jsp页面中的springUser.validateName(name);
的springUser 未定义 不用spring 的bean方式 就没有问题
那位高手能帮帮小弟啊!

就是啊不加spring程序是没有问题啊
这些框架兼容性怎么这么差啊

如果这个问题解决不到大家用ssh框架的时候要慎用DWR啊!!!
[解决办法]
不会啊，我用SSH+DWR工作得好好的啊
user.xml，dwr配置文件：
<?xml version= "1.0 " encoding= "GBK "?>
<!DOCTYPE dwr PUBLIC "-//GetAhead Limited//DTD Direct Web Remoting 2.0//EN " "http://www.getahead.ltd.uk/dwr/dwr20.dtd ">
<dwr>
<allow>
<!-- logoutDWR -->
<create creator= "spring " javascript= "Logout ">
<param name= "beanName " value= "logoutDWR "/>
<include method= "executeString "/>
</create>
dwr-user.xml，spring配置文件：
<?xml version= "1.0 " encoding= "UTF-8 "?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN "
"http://www.springframework.org/dtd/spring-beans.dtd ">
<beans>
<bean id= "logoutDWR " class= "com.aherp.voice.dwr.BusinessDWR ">
<property name= "name " value= "logout " />
</bean>
java文件：
package com.aherp.voice.dwr;
import java.util.HashMap;
import java.util.Map;
import javax.servlet.http.HttpServletRequest;
import com.aherp.voice.services.interfaces.IBusinessService;
import com.aherp.voice.util.SpringContextLoaderListener;
public class BusinessDWR {
private String name = null;
private String paramKey = null;
public Object executeMap(Map <String, String> requestMap, HttpServletRequest request) throws Exception{
IBusinessService businessService = (IBusinessService)SpringContextLoaderListener.getContext().getBean(name + "Service ");
return businessService.service(requestMap, request);
}
/**
* 执行单个参数的方式，单个参数以name+Param方式存放于request
* @param requestString
* @param request
* @return
* @throws Exception
*/
public Object executeString(String requestString, HttpServletRequest request) throws Exception{
Map <String, String> paramMap = new HashMap <String, String> ();
if(paramKey == null)
paramKey = name + "Param ";
paramMap.put(paramKey, requestString);
return executeMap(paramMap, request);
}
public void setName(String name) {
this.name = name;
}
public void setParamKey(String paramKey) {
this.paramKey = paramKey;
}
}

忘记说了，环境是:struts1.3.5+spring2.1+hibernate3.2+dwr2.0
[解决办法]
那你看我的项目中用dwr有什么问题啊
[解决办法]
?????????
[解决办法]
因为你的dwr模块根本就没有成功加载dynamicCheck
这个 <param name= "location " value= "applicationContext.xml "> </param> 不需要
applicationContext.xml应该在web.xml的context-param里配置
[解决办法]
你可以分两步，首先，写一个action看是否能够调用到你的springBean，如果可以的话，然后再将这个springBean配置到dwr里。
只需要
<allow>
<!-- GetServerPressure -->
<create creator= "spring " javascript= "SpringBeanFunction ">
<param name= "beanName " value= "springBeanName "/>
<include method= "executeString "/>
</create>
</allow>
这样就OK了
BTW，你调用的Bean方法最后需要一个HttpServletRequest参数
[解决办法]
你调用的Bean方法最后需要一个HttpServletRequest参数
这是什么意思
