返回一个List，alert出里面的数据相同，十万火急5

下面这段代码，我运行后alert出来全是相同的东西，那问题就应该在searchService.getSearchResults(request,fillPage);返回的List里，但我自己把这个方法单独验证了下，好像是没问题的，List里存的是不一样的results，这种情况怎么debug Java代码啊？

function doSearch(type){
	var result=document.getElementById("result");
	var pagingdiv=document.getElementById('paging');
	result.innerHTML="";
	pagingdiv.innerHTML="";
	
	if(type!='paging'){
		var startindexinput=document.getElementById('startindex');
		startindexinput.value="1";
	}
	
	request={startindex:1,query:""};
	DWRUtil.getValues(request);
	//DWREngine.setAsync(true);

	searchService.getSearchResults(request,fillPage);
	
	//DWREngine.setAsync(false);
}

function fillPage(data){
	
	alert(DWRUtil.toDescriptiveString(data,2));

	var resultdiv=document.getElementById('result');
	var pagingdiv=document.getElementById('paging');
	
	resultdiv.innerHTML="";
	pagingdiv.innerHTML="";
	
	if(data.length==0){
		resultdiv.innerHTML="<span>sorry, we can't find what you want...</span>";
		return;
	}

	if(null!=data){
		
		for(var i=0;i<data.length;i++){
			//alert(data[i].id);
			var results=data[i];
			alert(results);
			var ele=document.createElement('div');
			ele.setAttribute('id','info'+i);
			ele.innerHTML="<span>loading..</span>";
			resultdiv.appendChild(ele);
			var res=document.getElementById('info'+i);
				res.innerHTML = "<a href=\"" + data[i].url + "\">"
						+ "<font color=\"#0033CC\">" + results.title
						+ "</font></a><br /><font color=\"#008000\">"
						+ data[i].content + "</font><br /><br /><br />";

				resultdiv.appendChild(res);
			}
		}

public  class SearchServiceImpl implements SearchService{

	public List<SearchResults>  getSearchResults(SearchRequest request){

		List<SearchResults> list=new ArrayList<SearchResults>();
                          //省去一些代码

			      for(int i=startindex;i<=endindex;i++){
				SearchResults results=new SearchResults();
				results.setMinpage(startpage);
				results.setMaxpage(endpage);
				results.setHasnext(hasnext);
				results.setStartindex(startindex);
				Document doc =hits.doc(i-1);
				String pageid=doc.get("pageid");
				String pagetitle=doc.get("title");
				String pageurl=doc.get("url");
				String pagecontent=choose(doc.get("content"),request.getQuery());
				results.setId(pageid);
				results.setTitle(pagetitle);
				results.setUrl(pageurl);
				results.setContent(pagecontent);
				list.add(results);
				}
			}

		}catch(Exception e){
			e.printStackTrace();
		}
		return list;
	}

下面是我单独验证返回的list的值的方法
验证输出证明list里的数据是不一样的

这种情况怎么debug Java代码啊？

没明白你想怎么个DEBUG

不就用eclipse，或netbean自带的debug就可以了吗
启动的时候以debug方式起动~~

额。。。代码都在这了，为什么我传给回调函数的值，alert出来全是一样的啊，我验证过，传过去的应该是不一样的值啊

这个不是一张JSP页面么？都是JS和html标签，没DUBUG过。。。跟debug Java代码一样？
