dwr 引用util.js,engine.js,beanName.js路径问题如果引用util.js,engine.js,beanName.js的jsp页面在webRoot下面,则<script type="text/javascript" src="dwr/engine.js"/></script>

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

<script type="text/javascript" src="dwr/interface/beanName.js"></script>就可以正确引用，若引用util.js,engine.js,beanName.js的jsp页面不在webRoot下面,则必须加上<%=request.getContextPath() %>即变成了<script type="text/javascript" src="<%=request.getContextPath() %>/dwr/engine.js"/></script>

<script type="text/javascript" src="<%=request.getContextPath() %>/dwr/util.js"/></script>

<script type="text/javascript" src="<%=request.getContextPath() %>/dwr/interface/beanName.js"></script><%=request.getContextPath() %>这个方法应该能解决许多webRoot路径问题。很多连接的首页在webRoot下，不会引起路径问题若不在webRoot下，就会出现路径问题。都是由相对路径引出的问题。request.getContextPath()是工程名,也就是发布到web服务器的虚拟目录,比如/Sucre 补充：<script type="text/javascript" src="dwr/engine.js"/></script>这里的class="lazyload" src="data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAEAAAABCAYAAAAfFcSJAAAAAXNSR0IArs4c6QAAAARnQU1BAACxjwv8YQUAAAAJcEhZcwAADsQAAA7EAZUrDhsAAAANSURBVBhXYzh8+PB/AAffA0nNPuCLAAAAAElFTkSuQmCC" data-original="dwr/engine.js"中的dwr要与web.xml中的<url-pattern>相对应<!-- 指定核心Servlet的URL映射 -->
