大家好，我正在尝试使用 JCO3 库在 java 中实现 webService。

我已经作为 WAR 导出到服务器上的 webapps 文件夹中，但是当我尝试在 Windows 7 32 位的服务器（Tomcat 7）上运行时。

这是一个网络动态项目。我使用了一个名为（sapjco3.jar，这个 jar 带来了一个 sapjco3.dll）的 sap 库。还有一个 json-simple-1.1.1.jar。

出现下一个错误：

当我作为 JAVA 应用程序运行时，此应用程序运行良好。

我希望你的帮助问候

使用eclipse构建war文件时，一定要在“Deployment Assemblies”（项目属性）中有所有需要的运行时库和项目依赖。

对于动态 Web 项目，类路径仅用于编译您的源代码。部署程序集将作为 jar 文件打包到 WAR-File 内的 WEB-INF/lib 文件夹中。
