Hello
How can i use the Java Connector to call tRFC.
Use createTD() and confirmTD() ??
Is there any sample code or refernce guide??
Regards,
Kit
hi Chun
here is a sample code to call a RFC using JCo.
you may google and download the required libraries from the web. the downloads will have demo code with them too.
import com.sap.mw.jco.*;
public class TutorialBapi1 extends Object {
JCO.Client mConnection;
JCO.Repository mRepository;
public TutorialBapi1() {
try {
// Change the logon information to your own system/user
mConnection =
JCO.createClient("001", // SAP client
"<userid>", // userid
"****", // password
"EN", // language
"<hostname>", // application server host name
"00"); // system number
mConnection.connect();
mRepository = new JCO.Repository("asdf", mConnection);
}
catch (Exception ex) {
ex.printStackTrace();
System.exit(1);
}
JCO.Function function = null;
JCO.Table codes = null;
try {
function = this.createFunction("BAPI_COMPANYCODE_GETLIST");
if (function == null) {
System.out.println("BAPI_COMPANYCODE_GETLIST" +
" not found in SAP.");
System.exit(1);
}
mConnection.execute(function);
JCO.Structure returnStructure =
function.getExportParameterList().getStructure("RETURN");
if (! (returnStructure.getString("TYPE").equals("") ||
returnStructure.getString("TYPE").equals("S")) ) {
System.out.println(returnStructure.getString("MESSAGE"));
System.exit(1);
}
codes =
function.getTableParameterList().getTable("COMPANYCODE_LIST");
for (int i = 0; i < codes.getNumRows(); i++) {
codes.setRow(i);
System.out.println(codes.getString("COMP_CODE") + 't' +
codes.getString("COMP_NAME"));
}
}
catch (Exception ex) {
ex.printStackTrace();
System.exit(1);
}
try {
codes.firstRow();
for (int i = 0; i < codes.getNumRows(); i++, codes.nextRow()) {
function = this.createFunction("BAPI_COMPANYCODE_GETDETAIL");
if (function == null) {
System.out.println("BAPI_COMPANYCODE_GETDETAIL" +
" not found in SAP.");
System.exit(1);
}
function.getImportParameterList().
setValue(codes.getString("COMP_CODE"), "COMPANYCODEID");
function.getExportParameterList().setActive(false, "COMPANYCODE_ADDRESS");
mConnection.execute(function);
JCO.Structure returnStructure =
function.getExportParameterList().getStructure("RETURN");
if (! (returnStructure.getString("TYPE").equals("") ||
returnStructure.getString("TYPE").equals("S") ||
returnStructure.getString("TYPE").equals("W")) ) {
System.out.println(returnStructure.getString("MESSAGE"));
}
JCO.Structure detail =
function.getExportParameterList().
getStructure("COMPANYCODE_DETAIL");
System.out.println(detail.getString("COMP_CODE") + 't' +
detail.getString("COUNTRY") + 't' +
detail.getString("CITY"));
}
}
catch (Exception ex) {
ex.printStackTrace();
System.exit(1);
}
mConnection.disconnect();
}
public JCO.Function createFunction(String name) throws Exception {
try {
IFunctionTemplate ft = mRepository.getFunctionTemplate(name.toUpperCase());
if (ft == null)
return null;
return ft.getFunction();
}
catch (Exception ex) {
throw new Exception("Problem retrieving JCO.Function object.");
}
}
public static void main (String args[]) {
TutorialBapi1 app = new TutorialBapi1();
}
}
