Logon Screen Modificatio : Using JCo for Executing a Func Module in SAP R/3

Question

Hi all
   I am new to Portal(EP: 6.0: SP12) and JCo.
   We are customizing the Logon Screen of the Portal to include a CLIENT field.
    And  we are planning to Call a Z Function Module present in the R/3 of the specified client(in the Logon Screen) using JCO.
    But i am really new to the Environment..
    Could anyone please help in carrying out this work???
    And also i would like to know how a Fuc Module can be called with the help of JCO. Providing a sample Code would really help me a lot!!!!!!  
Thanks

Hi Kam
You need to create a connection to that R/3 system for that.
Try the following code:
creating connection:
=====================
IConnectorGatewayService cgService = (IConnectorGatewayService)
     PortalRuntime.getRuntimeResources().
     getService(IConnectorGatewayService.KEY);
IConnection con = cgService.getConnection("systemalias",request);
ConnectionProperties cp = new ConnectionProperties(request.getLocale(),request.getUser());
IInteraction ix = con.createInteractionEx();
IInteractionSpec ixspec = ix.getInteractionSpec();
ixspec.setPropertyValue("inputParameter","BAPI_SALESORDER");
RecordFactory rf = ix.getRecordFactory();
MappedRecord input = rf.createMappedRecord("inputParameter");
input.put("EMPLOYEE_NUMBER",empNo);
input.put("EMPLOYEE_NAME",empName);
BAPI_SALESORDER==>calling fuction
EMPLOYEE_NUMBER,EMPLOYEE_NAME===>parameter name
empNo,empName===>parameter value
<u>To retrive the value:</u>
============================
MappedRecord output = (MappedRecord)ix.execute(ixspec,input);
object rs = null;
object result = output.get("SALES_ORDERS");
if(result instanceof IRecordSet) {
     rs = (IRecordSet)result;
con.close();
Required jar files:
====================
com.sap.portal.ivs.connectorserviceapi.jar,                                  genericconnector.jar,
                   connector.jar,
                   activation.jar
