创建Web服务客户端的NoSuchMethodError

Question

我是新来的java和web服务和axis2。我最近使用一些教程创建了一个Web服务。当我第一次跟着Eclipse的教程时，让我创建一个客户端。但是，当我尝试创建一个新项目和一个新的Web服务客户端时，它给出NoSuchMethodError。这究竟是这样的：使用axis2-1.6.1

IM和它说java的合规性水平为6 我GOOGLE了它，但无法找到相关的解决这个问题。 任何帮助表示赞赏。

Answer 1

问题是Eclipse“找不到东西”。

下面是一个例子;这里的解决方案是：

1. 确保做了部署

当所有必需的.jar库被列入项目

选择类加载“第一搜索本地班”

Error in AXIS2 when i try publish ODI web services

Answer 2

请按照以下说明操作。

1. 确保您的网络提供服务的服务器英寸请通过查看您的Web服务的WSDL来检查它。
2. 之后遵循这些文章的一个指令，

web-service-client-using-eclipse-axis2
BottomUpAxis2WebService

它为我的罚款。确保您的代码插件已正确安装在eclipse上。

Answer 3

我有同样的问题，并通过检查我的WEB-INF/lib来解决。
我有两个任何AXIS2 jar文件在我的WEB-INF。
如果来自两个不同版本的axis2的jar文件被复制到WEB-INF，也会发生这种情况。

希望它的工作原理:-)
