DWR+STRUTS2异常，新手上路

Question

我的dwr.xml配置如下 
<dwr>
   <allow>
        <create creator="new" javascript="validator">
            <param name="class" value="org.apache.struts2.validators.DWRValidator"/>
        </create>
        <convert converter="bean" match="com.opensymphony.xwork2.ValidationAwareSupport"/>
    </allow>
    <signatures>
        <![CDATA[
        import java.util.Map;
        import org.apache.struts2.validators.DWRValidator;
        DWRValidator.doPost(String, String, Map<String,String>);
        ]]>
    </signatures>
</dwr>照书抄的、出现一下错误
2008-10-31 14:12:36 uk.ltd.getahead.dwr.util.CommonsLoggingOutput warn
警告: Missing type info for doPost(2<0>). Assuming this is a map with String keys. Please add to <signatures> in dwr.xml

警告: Missing type info for doPost(2<1>). Assuming this is a map with String keys. Please add to <signatures> in dwr.xml
2008-10-31 14:12:36 uk.ltd.getahead.dwr.util.CommonsLoggingOutput info
信息: Exec[0]: validator.doPost()
2008-10-31 14:12:36 uk.ltd.getahead.dwr.util.CommonsLoggingOutput error
严重: No converter found for com.opensymphony.xwork2.ValidationAwareSupport我英语水平不好，查了下似乎说我应该在signatures段里配置doPost可是我配置了啊？
是不是要配doPost两个参数的？高手给个示例，谢谢！！

Answer 1

struts 2.0没用过，
但是dwr +struts 1.x 是需要在web.xml里配置启动参数。
dwr要大于struts的启动参数值

Answer 2

dwr要在web.xml里配置一下。
<!-- 加入DWR框架 --> <servlet>
     <servlet-name>dwr-invoker</servlet-name> 
     <servlet-class>org.directwebremoting.servlet.DwrServlet</servlet-class>
 <init-param>
<param-name>config-dwr</param-name>
<param-value>/WEB-INF/dwr.xml</param-value>
</init-param>
    <init-param> 
     <param-name>debug</param-name> 
     <param-value>true</param-value> 
    </init-param> 
   </servlet> 
   <servlet-mapping>
    <servlet-name>dwr-invoker</servlet-name> 
    <url-pattern>/dwr/*</url-pattern> 
   </servlet-mapping>  
     
<!-- 加入DWR框架结束 -->  另外web-inf下的dwr.xml要作一下配置。例：<dwr>
<allow>
<create creator="new" javascript="TreeViewMgr">
<param name="class" value="com.yctech.wbflow.treeview.TreeViewMgr" />
<include method="isExistNodeName" />
<include method="getPosition" />
<include method="canExpand" />
</create>
</allow>
</dwr>

Answer 3

楼上正解，web.xml中：
  
  <servlet>
    <servlet-name>dwr-invoker</servlet-name>
    <servlet-class>org.directwebremoting.servlet.DwrServlet</servlet-class>
    <init-param>
      <param-name>config</param-name>
      <param-value>WEB-INF/conf/system/dwr.xml</param-value>
    </init-param>
    <init-param>
      <param-name>debug</param-name>
      <param-value>true</param-value>
    </init-param>
    <init-param>
      <param-name>scriptCompressed</param-name>
      <param-value>false</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
  </servlet>
