Call rfc from Java Web application.

Hi:

I am new to SAP Java programming.

I am developing a java web application on SAP NW SP16.

I need to call a rfc and process the data to be displayed on a jsp page.

I have few questions...

1) Can I use the JCO destination created in thru wed dynpro content administrator, to connect to sap and execute the rfc/bapi?

2) How would I create and access the model (rfc)?

3) Are the required jar and dll(rfc32.dll ... ) files available on the server?

Any help would be greatly appreciated.

Thanks.
