我在用Java调用WebService服务时，出现了这个错误

Exception in thread "main" java.lang.NoSuchMethodError: org.apache.commons.httpclient.MultiThreadedHttpConnectionManager.setParams(Lorg/apache/commons/httpclient/params/HttpConnectionManagerParams;)Vat org.codehaus.xfire.transport.http.CommonsHttpMessageSender.createClient(CommonsHttpMessageSender.java:228)at org.codehaus.xfire.transport.http.CommonsHttpMessageSender.open(CommonsHttpMessageSender.java:129)at org.codehaus.xfire.transport.http.HttpChannel.sendViaClient(HttpChannel.java:121)at org.codehaus.xfire.transport.http.HttpChannel.send(HttpChannel.java:48)at org.codehaus.xfire.handler.OutMessageSender.invoke(OutMessageSender.java:26)at org.codehaus.xfire.handler.HandlerPipeline.invoke(HandlerPipeline.java:131)at org.codehaus.xfire.client.Invocation.invoke(Invocation.java:79)at org.codehaus.xfire.client.Invocation.invoke(Invocation.java:114)at org.codehaus.xfire.client.Client.invoke(Client.java:336)at org.codehaus.xfire.client.Client.invoke(Client.java:368)at bao.main(bao.java:26)

根据帖子http://bbs.csdn.net/topics/390183100中的回复得到了解决办法

引入了多余的包，只需把commons-httpclient.jar去掉，只留下commons-httpclient-3.0.1.jar就行了
