我开发了一个与SAP集成的Java Web应用程序.我用Linux Server和Tomcat 7.0开发了它.我在WEB-INF / lib文件夹中添加了sapjco3.jar和libsapjco3.so.它工作正常的本地服务器.但是在远程服务器中部署WAR文件时会产生以下错误.

从Tomcat服务器ping目标时出现错误.

private JCoDestination dest;    
    public Connection(SapSystem system)  {

    dest = JCoDestinationManager.getDestination(SAP_SERVER);

            dest.ping();
}

问题的原因是什么？
