java通过jco连接sap rfc，并处理rfc函数-java connection through jco sap rfc, and process rfc function

SAP Jco Example, using connection with RFC

用java实现了调用SAP的RFC函数，创建jco连接池-jco connection pool

通用的jco。解析以SAP RFC的三种传输的数据结构定义的Json。实现sap 通过jco 与java进行数据交互(Generic jco. Parse the Json defined by the three transport data structures of SAP RFC. The implementation of sap through JCO and Java data interaction)
