使用JCO3創建一個帶有Java的WebService

Question

嗨，人們即時嘗試實現一個web服務在Java中使用JCO3庫。

我已經將WAR作爲WAR導出到服務器上的webapps FOLDER中，但是當我嘗試在Windows 7 32位上的服務器（Tomcat 7）上運行tu時。

這是一個網絡動態項目。 我使用一個名爲（sapjco3.jar，這個jar帶來sapjco3.dll）的sap庫。 也是一個json-simple-1.1.1.jar。

出現的nextS錯誤：當我作爲一個Java應用程序運行

這個應用程序工作正常。

我希望YOR HELP 問候

當使用Eclipse來構建一個WAR文件，一定要在「部署大會」所有必要的運行時庫和項目依賴關係（項目屬性）。

對於動態Web項目的類路徑僅用於編譯源代碼。部署程序集將作爲jar文件打包到WAR-File內的WEB-INF/lib文件夾中。
