JCO exportParameter

[Former Member]

Hello SAP experts,

I´m a student from Germany. I have a Problem with die Exportparameter of a SAP Function in a JAVA

Application.

The Function in the SAP System works. Ihe Importparameter and the Exportparameter of the Funktion also.

I tested it in the SAP System. But the Exportparamter in my JAVA Application in the Form of a String

unfortunately has the Value of null.

Here ist my Coding:

import com.sap.mw.jco.*;

import com.sap.mw.jco.JCO.ParameterList;

import java.util.*;

import java.io.*;

public class JCOTestString {

public static JCO.Client client;

public static final String SID = "SAP System";

public static IRepository repository;

public static void main(String[] args){

try {

JCO.Pool pool = JCO.getClientPoolManager().getPool(SID);

if (pool == null) {

int maxConnections = 1;

JCO.addClientPool(SID, maxConnections,

"00",

"RFC",

"password",

"DE",

"sapserver",

"00");

}

repository = JCO.createRepository("Repository", SID);

IFunctionTemplate ftemplate = repository

.getFunctionTemplate("Z_TEST");

JCO.Function function = new JCO.Function(ftemplate);

function.getImportParameterList().setValue("KEY", "TEST1");

String g = function.getExportParameterList().getString("RESULT");

System.out.print(g); //---> unfortunately NULL

} catch (Exception e) {

JCO.releaseClient(client);

// Fehler falls catch ausgeführt wird.

System.out.println("Fehler abgefangen:

" + e);

}

JCO.releaseClient(client);

}

}

Is anyone able to help me and to solve the Problem?

Regards

Hello Marc,

In your code i am missing the

"client.execute(function);"

That is to be done after the setvalue of the import!!

Good Luck,
