Error in JCo while connecting BAPI SALES ORDER.

Question

package com.sap;
import com.sap.mw.jco.JCO;
import com.sap.mw.jco.JCO.Exception;
import com.sapportals.portal.prt.component.AbstractPortalComponent;
import com.sapportals.portal.prt.component.IPortalComponentRequest;
import com.sapportals.portal.prt.component.IPortalComponentResponse;
public class DirectBAPI extends AbstractPortalComponent
    public void doContent(IPortalComponentRequest request,   
         IPortalComponentResponse response)
             JCO.Client mConnection;
              JCO.Repository mRep;
      response.write("Connecting..........");
    try
                                // Change the logon information to your own system/user
   mConnection =  JCO.createClient("<client number>",  "<user Id>",  "password",                             
          null,                 // language
     "application server number",                "<system no..>");       
           response.write("Reached");
         mConnection.connect();                // connecting JCo...
mRep = new JCO.Repository("SAPJCo", mConnection);   //use JCo    Repository....
     response.write("Connected Succesfully");
    //response.write( mConnection.getAttributes() );
   // mConnection.disconnect();
catch (Exception ex)
     ex.printStackTrace();
       response.write(ex.getMessage());
   JCO.Function function = null;
   JCO.FunctionTemplate ftp = null;        
   JCO.Table codes = null;
try
         ftp = mRep.getFunctionTemplate();
         function = ftp.getFunction();
         function = this.createFunction("BAPI_SALESORDER_GETSTATUS");   
                                         // Accessing SALES_ORDER_GETSTATUS.
         if (function == null)
             response.write("BAPI_COMPANYCODE_GETLIST"  +  " not found in SAP.");
   catch (Exception exx)
      response.write(exx.getmessage() );
   In the above code while while connecting to the BAPI SALES ORDER GET_STATUS an error is coming for JCO connection for the JCo Repository.
The method createFunction() is undefined for the type of Project.
plz guide how to rectify this so as to connect BAPI SALES ORDER thru JCo connection.
Thanx in advance.

Hi,
The below Code is helpful for Calling BAPI's Using JCO .
public class TestJCO {
     JCO.Client mConnection;
      JCO.Repository mRepository;
      public TestJCO() {
        try {
           // Change the logon information to your own system/user
//           mConnection =
//             JCO.createClient("800", // SAP client
//                "USERID",           // userid
//                "password",               // password
//                null,                 // language
//                "appserver hostname",         // application server host name
//                "00");                // system number
          mConnection =
            JCO.createClient("002", // SAP client
               "userid",           // userid
               "password",               // password
               null,                 // language
               "app server host name",         // application server host name
               "00");                // system number
           mConnection.connect();
           mRepository = new JCO.Repository("companyname", 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) {
          TestJCO app = new TestJCO();
Please Check your code with above code.
