Java calls the sap RFC Function

Recently, the project needs to be connected to sap, write data in the project to the SAP system, and communicate with sap to determine to use the RFC function provided by SAP. The specific call method is as follows:

You need to add sapjco. jar to the project.

You also need to put librfc32.dll and sapjcorfc. dll under javahome \ JRE \ bin \; otherwise, the following exception occurs: [No sapjcorfc in Java. Library. Path]. java. Library. Path
