Question

我正在尝试从WSO2 ESB中的服务B向WSO2 DSS中的服务A发送消息。我使用JAX-WS生成了一个客户端，可以直接访问A. 从Java代码，但当我导出与Axis2服务相同的代码并将其放入ESB时，我收到以下错误：

这是在ESB之外工作的代码：

public static String echoString(java.lang.String in) {
    Echo service = Echo();
    EchoPortType port = service.getEchoHttpSoap12Endpoint(); <-- ERROR HERE
    BindingProvider bp = (BindingProvider)port;
    bp.getRequestContext().put(BindingProvider.ENDPOINT_ADDRESS_PROPERTY,LOCAL_ENDPOINT);
    return port.echoString(in);
}

有任何解决此问题的建议吗？

如果您使用生成的客户端作为＆＃34; jar依赖＆＃34;，您需要将此jar放到文件夹src / main / resources / lib 或者把你的罐子放到＆＃34; dropins＆＃34; wso2esb的文件夹。

从WSO2 ESB调用WSO2 DSS中的服务
