我看了好多次，还是没发现什么问题啊，大家帮我看看哈，谢谢了！

Answer 1

先看看你tomcat正常启动没，然后再检查url地址是否正确

Answer 2

该问题已经解决，现在遇到了下一个问题，就是我定义的patentSearchService.getSearchResults函数在网页上执行不了，但是在java环境下可以执行，能得到搜索结果，是不是dwr 和spring没有配置好啊？

Answer 3

404明显URL路迳或业面跳转出现错误

Answer 4

有什么错误信息,看相应的包在jsp中导入没

Answer 5

没有提示具体的错误信息，需要导入的就是一个patentSearchService.js
script type='text/javascript' src="${pageContext.request.contextPath}/dwr/engine.js"></script>
<script type='text/javascript' src="${pageContext.request.contextPath}/dwr/util.js"></script>
<script type='text/javascript' src="${pageContext.request.contextPath}/dwr/interface/patentSearchService.js"></script>

Answer 6

<create creator="spring" javascript="patentSearchService">
<param name="beanName" value="patentSearchService" />
</create>creator="spring"  改成 creator="new"试试
检查你JS调用getSearchResults参数个数和后台是否一样，回调函数写对没

Answer 7

看一下tomcat 服务器里面（tomcat 的安装目录）发布的项目名称是否和你在地址栏输入的项目名称相同
再仔细检查配置文件
再仔细检查 Action 提交的路径

Answer 8

我之前用new试过，不行，我的配置是这样的：
<dwr>
<allow>

<create creator="spring" javascript="patentSearchService">
<param name="beanName" value="patentSearchService" />
</create>

<!-- Bean for Search -->
<convert converter="bean"
match="com.luceneheritrixbook.searchengine.bo.PatentSearchResult">
</convert>
<convert converter="bean"
match="com.luceneheritrixbook.searchengine.bo.SearchResults">
</convert>
<convert converter="bean"
match="com.luceneheritrixbook.searchengine.bo.SearchRequest">
</convert>

</allow>
</dwr>applicationContext.xml
<bean id="patentSearchService"
class="com.luceneheritrixbook.searchengine.service.impl.PatentSearchServiceImpl" singleton="false">
<property name="patentSearchResultDao"><ref local="patentSearchResultDao"/></property>
</bean>
<bean id="patentSearchResultDao"
class="com.luceneheritrixbook.searchengine.service.dao.impl.PatentSearchResultDaoImpl" singleton="false">
<property name="dataSource"><ref local="myDataSource"/></property>
</bean>web.xml
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/classes/applicationContext.xml</param-value>
</context-param>...
<listener>
<listener-class>
org.springframework.web.context.ContextLoaderListener
</listener-class>
</listener>

<servlet>
<display-name>DWR Servlet</display-name>
<servlet-name>dwr-invoker</servlet-name>
<servlet-class>uk.ltd.getahead.dwr.DWRServlet</servlet-class>
<init-param>
<param-name>debug</param-name>
<param-value>true</param-value>
</init-param>
</servlet>
在JSP页面的引用是这样的：
script type='text/javascript' src="${pageContext.request.contextPath}/dwr/engine.js"></script>
<script type='text/javascript' src="${pageContext.request.contextPath}/dwr/util.js"></script>
<script type='text/javascript' src="${pageContext.request.contextPath}/dwr/interface/patentSearchService.js"></script>我没看出配置哪里不对啊？你们帮我看看吧，谢谢了，另外我的getSearchResults函数是这样的：
public SearchResults getSearchResults(SearchRequest request)在JSP中的调用是这样的：
function doSearch(type){
window.alert('hehe'); var result = document.getElementById("result");
var pagingdiv = document.getElementById('paging');
result.innerHTML="aaaaaa";
pagingdiv.innerHTML = ""; if (type != 'paging') {
window.alert('if');
var startindexinput = document.getElementById('startindex');
window.alert('if2');
startindexinput.value = "1";
window.alert('if3');
}
window.alert("test");
request = {startindex:1, query:""};

DWRUtil.getValues(request);
window.alert('dwrtest');
patentSearchService.getSearchResults(request, fillPage);
window.alert('getSearchResultsTest');
}

function fillPage(data){

window.alert('testFILLPAGE');
var list = data.results;
var resultdiv = document.getElementById('result');
var pagingdiv = document.getElementById('paging'); resultdiv.innerHTML = "";
pagingdiv.innerHTML = "";

if (list.length == 0) {
resultdiv.innerHTML = "<span>Sorry, we can't find what you want...</span>";
return;
}

for(var i=0; i<list.length; i++) {
var ele = document.createElement('div');
ele.setAttribute('id','info' + list[i]);
ele.innerHTML = "<span>loading..</span>";
resultdiv.appendChild(ele); }

minpage = data.minpage;
maxpage = data.maxpage;
startindex = data.startindex;
hasnext = data.hasnext;

if (minpage != 1) {
var link = document.createElement('a');
link.setAttribute("href","javascript:paging('" + ((minpage-11)*10+1) + "')");
link.innerHTML = "前10页<<";
pagingdiv.appendChild(link);
}

for (var j=minpage; j <=maxpage; j++)
{
if ((j-1)*10+1 != startindex)
{
var link = document.createElement('a');
link.setAttribute("href","javascript:paging('" + ((j-1)*10+1) + "')");
link.innerHTML = "第" + j + "页";
pagingdiv.appendChild(link);
}
else {
pagingdiv.innerHTML += ("第" + j + "页");
}
}

if (hasnext == 1) {
var link = document.createElement('a');
link.setAttribute("href","javascript:paging('" + (maxpage*10+1) + "')");
link.innerHTML = ">>后10页";
pagingdiv.appendChild(link);
}

}}
执行到patentSearchService.getSearchResults(request, fillPage);
就走不下去了，在fillPage中没有弹出的对话框,所以表明没有进入这个回调函数，但不知道为什么啊。

Answer 9

暂时没看出什么问题、
你先写个简单的没有参数的方法调试一下看看dwr能否执行，如果这都没能正确执行才能确定是你配置问题~
