Question

当我运行我使用的web服务客户端时，我收到以下错误：eclipse，j2sdk1.4.2_13，axis1.0和WSDL文件。

java.lang.NoClassDefFoundError: javax/servlet/ServletContext

    at com.example.xmlns.SOAPEventSourceBindingStub.<init>(SOAPEventSourceBindingStub.java:17)
    at com.example.xmlns.Cliente.main(Cliente.java:16)
Exception in thread "main"

客户这样做：
SOAPEventSourceBindingStub stub = new SOAPEventSourceBindingStub();

public SOAPEventSourceBindingStub() throws org.apache.axis.AxisFault {
     this(null); (this is line 17)
}

public SOAPEventSourceBindingStub(java.net.URL endpointURL, javax.xml.rpc.Service service) throws org.apache.axis.AxisFault {
     this(service);
     super.cachedEndpoint = endpointURL;
}

public SOAPEventSourceBindingStub(javax.xml.rpc.Service service) throws org.apache.axis.AxisFault {
    if (service == null) {
        super.service = new org.apache.axis.client.Service(); (this is line 27)
    } else {
        super.service = service;
    }
        ...

您需要在类路径中使用servlet Jar或使用更新版本的轴。

注意：即使在客户端，AXIS 1.0版本也需要servlet JAR文件，否则会出现以下异常：（即将发布的1.1版应该有此修复）
Exception in thread "main" java.lang.NoClassDefFoundError: javax/servlet/ServletContext
     at java.lang.Class.getDeclaredMethods0(Native Method)
     at java.lang.Class.privateGetDeclaredMethods(Class.java:1613)
     at java.lang.Class.getMethod0(Class.java:1732)
     at java.lang.Class.getDeclaredMethod(Class.java:1219)
     ...

桌面应用程序存在类似问题。在Netbeans中，这突然出现了，尽管我只更改了不相关的SQL查询。问题包仍然在我的主要包中，但找不到。

解决了在我的主程序包中重命名有问题的类（并在需要时重命名）。同样更正了命名标准偏差（某些类名首字母是低位的）。
