/*
deploy.wsdd
*/<deployment xmlns="http://xml.apache.org/axis/wsdd/"
xmlns:java="http://xml.apache.org/axis/wsdd/providers/java">
<service name="BankServer" provider="java:RPC">
<parameter name="className" value="BankServer"/>

Answer 2

最后在zl_homework3文件夹下建文件：bank.txt
内容为：
0.0
用于程序中保存中间数据。

Answer 3

我按文章试了一遍.怎么出现下面异常阿?
哪位成功试过吗? Exception in thread "main" java.lang.NoClassDefFoundError: javax/wsdl/OperationT
ype
        at org.apache.axis.description.OperationDesc.<clinit>(OperationDesc.java
:58)
        at org.apache.axis.client.Call.addParameter(Call.java:948)
        at org.apache.axis.client.Call.addParameter(Call.java:983)
        at BankClient.main(BankClient.java:29)

Answer 4

NoClassDefFoundError表明你的classpath中没有这个class，你检查一下你的j2ee.jar包有没有加进classpath！
