EP 5.0 JCO Client Service

Hello,

Does anyone have a coded example of a dynpage/jspdynpage that makes multiple calls to an SAP BAPI or RFM in different methods of the dynpage/jspdynpage. I've read the SDN document and would like to ensure conceptually, I've got everything right. Mainly, ensuring that I'm optimizing the JCO client service in the following scenario:

public void onHeaderClick(Event event) {

// make call to SAP upon header click

using JCO client service... call BAPI

}

public void doProcessAfterInput() throws pageException {

// make call to SAP

using JCO client service.. call same or another BAPI while optimizing JCO client service

}

Thanks for all your help,

Michael
