我需要使用Eclipse在Java中創建Web服務客戶端，並使用onvif wsdl。在Eclipse中使用wsdl文檔構建Soap Web服務客戶端
我花了幾個小時沒有找到如何做到這一點，這是我第一次使用肥皂，我的經驗是在REST。
我試過很多教程像this創建Web服務客戶端，但是當我試圖選擇從我的本地磁盤的WSDL文件，日食顯示錯誤Could not retrieve the WSDL file ...，我使用的文件的鏈接結構是file:/C:/ONVIF/media.wsdl。
我需要使用任何支持WS-Notification的Java框架來實現我的客戶端。
請問您可以告訴我如何實現使用WSDL文件的客戶端Web服務。
我是否需要Web服務器來實現soap web服務客戶端？
如果是，爲什麼？
首先你想在任何服務器上部署你的web服務項目意味着tomcat或其他。 之後使用正在運行的服務器WSDL文件URL來創建客戶端。
爲什麼需要在服務器上創建Web服務項目？服務器部分已經從製造商部署在IP攝像機上。你能解釋更多嗎？ – 2012-01-10 04:31:43
由於web服務客戶端是tru執行wsdl文件，並且當您指定本地路徑時，則不存在任何執行環境，因此我們需要在服務器上部署並使用服務器URL來創建客戶端。 – 2012-01-10 04:47:50
如何從wsdl創建java文件？你推薦任何框架來使用它來實現客戶端 – 2012-01-10 05:06:45
您提供的WSDL無效。很可能是由於其中使用了大量的文檔標籤。您可以通過嘗試在SoapUI中加載來驗證這一點。您最好的選擇是與供應商聯繫，以確定他們是否擁有可以爲您提供的更清晰的WSDL版本。
這是否意味着它將工作，如果我刪除文檔標籤？我不確定這個？!!以及爲什麼它使用Visual Studio工作？ – 2012-01-12 18:34:42

我會建議使用的wsimport命令生成Web服務客戶端以使用Web服務。
該命令可以從CMD提示符被執行，
wsimport -d D:\WS-Client -extension -keep -XadditionalHeaders http://path-to-your-webserbice-wsdl-file/sampleWSDL?wsdl
上述命令的執行之後的所有生成的.class文件和.java（源）文件將被放置裏面d：\ WS-Client文件夾在wsdl文件中提到了正確的包結構。
只是忽略.class文件並複製整個包文件夾，並將其包含在消費者項目中以使用它。
這將是，你的源代碼中有部署的Web服務。只需要調用服務類和ohhla中的方法:)
我相信JAX-WS將支持此功能（客戶端支持作爲Java 6 API的一部分提供）。 – McDowell 2012-01-10 09:04:19
