JCO or SAP Connector Framework

Question

Hello
I have seen in these links that JCO is deprecated:

Developers are supposed to use SAP Connector Framework, but it seems that this is a Framework only useful from a Portal Application. What I want to do is to invoke RFCs in a R3 System from a webapp using struts. I have done this using JCO.
Should I implement it using another solution?
Thanks in advance

Hi Marcos,
You can, of course, use SAP JCO in simple Java Project by importing needed Jars.
I provide you a sample of connection class with method that you can use for calling a function.
You can use method "showFunctionParameters()" to test your connection...
