I'm getting this error when i run code.
java.lang.UnsatisfiedLinkError: no sapjco3 in java.library.path
I have added the jar(sapjco-3.0.jar) to folder and did set the path in the project.
Thanks.
You are missing the native implementation of the sap java connector. sapjco consists of a .jar for the java binding and a native library (an .so-file) for the platform specific binding.
You need an account on the sap service marketplace to access it. If you have one go to http://service.sap.com and there to Software Downloads / INstallations and upgrades / Browse / SAP Connectors / SAP JCO
Once you place sapjco3.dll, Do not forget to restart your eclipse with Admin rights.
