sapjco30/sapjco3.dll/sapjco3.jar SAP官网2017/7/18更新版本

sapjco30 SAP官网2017/7/18更新版本，Windows64位，Linux 64位。 因项目开发SAP RFC接口，使用sapjco3.dll/sapjco3.jar，而网上下载多个版本的sapjco3.dll都提示版本等级太低，最后从SAP官网上下载了2017/7/18更新的文件，使用后OK。

/**
 * Each application using Java Connector 3 deals with destinations. A destination represents a logical address 
 * of an ABAP system and thus separates the destination configuration from application logic. JCo retrieves
 * the destination parameters required at runtime from DestinationDataProvider and ServerDataProvider registered
 * in the runtime environment. If no provider is registered JCo uses the default implementation that reads the 
 * configuration from a properties file. It is expected that each environment provides a suitable 
 * implementation that meets security and other requirements. Furthermore only one DestinationDataProvider 
 * and only one ServerDataProvider can be registered per process. The reason behind this design decision 
 * is the following: the provider implementations are part of the environment infrastructure. 
 * The implementation should not be application specific and in particular must be separated from 
 * application logic. 
 * 
 * This example demonstrates a simple implementation of the DestinationDataProvider interface and shows how
 * to register it. A real world implementation should save the configuration data in a secure way.
