WSO2 ESB 5.0 上的运行时错误
Runtime error on WSO2 ESB 5.0
我正在尝试使用 WS02 ESB 5.0 每 15 秒调用一次 Web 服务,所以我有这个任务:
<?xml version="1.0" encoding="UTF-8"?>

均来自文档中显示的示例:

https://docs.wso2.com/display/ESB500/Sample+56:+Using+a+WSDL+Endpoint+as+the+Target+Endpoint(参见 "Building the sample")。
但是,我在启动 Carbon WSO2 ESB 服务器后遇到此错误:

任何人都可以告诉我发生了什么事吗?
非常感谢!
在 wsdl 端点中,uri 值必须是 WSDL 地址,而不是服务端点:
WSDL URI The URI of the WSDL. Click Test to test the URI.
因此,发送中介内的 WSDL 端点使用服务和端口名称从 WSDL 文档中提取服务端点,以在 wsdl 文档中找到它。
