关于ws异常处理咨询
哈哈，我是在myeclipse中调用亚马逊的ws，然后出错了，就是想咨询一下大神。
下面这个例子是我看的书中的一个程序，名字叫做JavaWebServicesUpandRunning
是MartinKalin编写的。
packagech02.ts.test;

importawsClient.AWSECommerceService;
importawsClient.AWSECommerceServicePortType;
importawsClient.ItemSearchRequest;
importawsClient.ItemSearch;
importawsClient.Items;
importawsClient.Item;
importawsClient.OperationRequest;
importawsClient.SearchResultsMap;
importjavax.xml.ws.Holder;
importjava.util.List;
importjava.util.ArrayList;

@SuppressWarnings("unused")
publicclassAmazonClientW{
publicstaticvoidmain(String[]args){
if(args.length<1){
System.err.println("Usage:javaAmazonClientW<accesskey>");
return;
}
finalStringaccess_key=args[0];
//Constructaserviceobjecttogettheportobject.
AWSECommerceServiceservice=newAWSECommerceService();
AWSECommerceServicePortTypeport=service.getAWSECommerceServicePort();
//Constructanemptyrequestobjectandthenadddetails.
ItemSearchRequestrequest=newItemSearchRequest();
request.setSearchIndex("Books");
request.setKeywords("quantumgravity");
ItemSearchsearch=newItemSearch();
search.getRequest().add(request);
search.setAWSAccessKeyId(access_key);
Holder<OperationRequest>operation_request=null;
Holder<List<Items>>items=newHolder<List<Items>>();
port.itemSearch(
search.getMarketplaceDomain(),
search.getAWSAccessKeyId(),
//search.getSubscriptionId(),
search.getAssociateTag(),
search.getXMLEscaping(),
search.getValidate(),
search.getShared(),
search.getRequest(),
operation_request,
items);
//Unpacktheresponsetoprintthebooktitles.
Itemsretval=items.value.get(0);//firstandonlyItemselement
List<Item>item_list=retval.getItem();//listofItemsubelements
for(Itemitem:item_list)
//eachIteminthelist
System.out.println(item.getItemAttributes().getTitle());
}
}上面是源码，
下面是出错的信息

400:BadRequest
应该是ws地址已经改了
