dwr框架，无法加载js问题，求解！

杨帆9527 2017-06-21 05:04:09

做好的项目，只用到了dwr框架，在我自己电脑上和服务器还有另一个同事电脑上运行都没问题，但是今天在一个同事的电脑上面运行项目，出现自定义的js找不到的问题，下面贴一下代码

页面引用的js路径



<script type="text/javascript" src="/BaiduMap/dwr/util.js"></script>

<script type="text/javascript" src="/BaiduMap/dwr/engine.js"></script>  

<script type="text/javascript" src="/BaiduMap/dwr/interface/sql.js"></script>

dwr.xml配置



<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE dwr PUBLIC "-//GetAhead Limited//DTD Direct Web Remoting 3.0//EN" "http://getahead.org/dwr/dwr30.dtd">



<dwr>

    <allow>

          <create creator="new" javascript="sql">   

            <param name="class" value="com.http.jdbc.SelectFromSql"/>   

          	<!-- <include method="selectFour"/>    

    		<include method=""/>   

    		<include method=""/> -->

          </create>

     </allow>

</dwr>

web.xml配置



<display-name>BaiduMap</display-name>

  

  	<servlet>  

        <servlet-name>dwr-invoker</servlet-name>  

        <servlet-class>org.directwebremoting.servlet.DwrServlet</servlet-class>  

        <init-param>  

            <param-name>debug</param-name>  

            <param-value>true</param-value>  

        </init-param>  

        <init-param>

             <param-name>crossDomainSessionSecurity</param-name>

             <param-value>false</param-value>

      	</init-param>

      	<init-param>

            <param-name>allowScriptTagRemoting</param-name>

            <param-value>true</param-value>

      	</init-param>

         

        <load-on-startup>1</load-on-startup>  

    </servlet>  

  

    <servlet-mapping>  

        <servlet-name>dwr-invoker</servlet-name>  

        <url-pattern>/dwr/*</url-pattern>  

    </servlet-mapping>

上面的配置个人没啥问题
下面是启动tomcat的时候，报的错误，不知道这是啥意思，请大神帮忙看看
