Jco does not commit

Question

Hi experts.
I have a problem with jco. I made a jsp page including jco that calls a CBO function module(RFC). When I run the page with debug mode, commit work is executed. But it's not work non-debug mode even though I execute 'BAPI_TRANSACTION_COMMIT' on the page. I don't know why it's not work. Below code is mine.
public String fileDocTest(String doc, String doctype)       {
  JCO.Client client = null;
  JCO.Repository rep = null;
  JCO.Function function = null;
  JCO.Function function_comm = null;
  String rstring = "";
  String docnum ="";
  String temp = "1";
  String temp1 = "SAP-SYSTEM";
  try
    client = SAPConnectionPool.getInstance().getConnection();
    rep = new JCO.Repository(repositoryName, client);
    CreateFunction crtFnc = new CreateFunction(rep);
    CreateFunction crtFnc2 = new CreateFunction(rep);
    function_comm = crtFnc.createFunction("BAPI_TRANSACTION_COMMIT");
    function = crtFnc2.createFunction("Z_1EH_UPLOAD_DOC_2");
    JCO.setMiddlewareProperty("jco.middleware.allow_start_of_programs","ftp;sapftp;sapftpa;sapkprotp;http;saphttp;saphttpa");  
    JCO.Structure imp_f_table_00 = function.getImportParameterList().getStructure("DOCUMENTDATA");
     imp_f_table_00.setValue("CPD","DOCUMENTTYPE");
     imp_f_table_00.setValue("CFPDOC","DESCRIPTION");
    JCO.Table imp_f_table_01 = function.getTableParameterList().getTable("DOCUMENTDESCRIPTIONS");
     imp_f_table_01.appendRow();
     imp_f_table_01.setValue("EN","LANGUAGE");
     imp_f_table_01.setValue("CfPDoc","DESCRIPTION");
    JCO.Table imp_f_table_02 = function.getTableParameterList().getTable("DOCUMENTFILES");
     imp_f_table_02.appendRow();
     imp_f_table_02.setValue( "1","ORIGINALTYPE");
     imp_f_table_02.setValue( "SAP-SYSTEM","STORAGECATEGORY");                            imp_f_table_02.setValue(doc,"DOCPATH");     
     imp_f_table_02.setValue(doctype,"WSAPPLICATION");
     client.execute(function);
     client.execute(function_comm);
                            JCO.ParameterList exp_f_table = function.getExportParameterList();
  catch (Exception ex)
      ex.printStackTrace(); 
      System.out.println("Caught an exception: \n" + ex);
  finally
      JCO.releaseClient(client);
      return docnum;
FM Z_1EH_UPLOAD_DOC_2 calls a standard FM API_DOCUMENT_MAINTAIN2.
If you have any inforamtion about JCO commit error, please let me know.
Regards.

Hi Nils.
Frankly I say, I try to commit in the source code of 'Z_1EH_UPLOAD_DOC_2" fucntion like below.
  CALL FUNCTION 'API_DOCUMENT_MAINTAIN2'
       EXPORTING: pf_transaction       = 'CV01'
                  documentdata         = documentdata
                  hostname             = hostname
                  change_number        = docbomchangenumber
                  valid_from           = docbomvalidfrom
                  revision_level       = docbomrevisionlevel
                  pf_ftp_dest          = pf_ftp_dest
                  pf_http_dest         = pf_http_dest
                  CAD_MODE             = CAD_MODE
       IMPORTING: documenttype         = documenttype
                  documentnumber       = documentnumber
                  documentpart         = documentpart
                  documentversion      = documentversion
                  return               = return
      TABLES:     characteristicvalues = characteristicvalues
                  classallocations     = classallocations
                  documentdescriptions = documentdescriptions
                  objectlinks          = objectlinks
                  documentstructure    = documentstructure
                  documentfiles        = documentfiles
                  longtext             = longtexts
                  components           = components.
   if return-type is initial or return-type =  'S'.
    commit work.
    if sy-subrc = 0.
      if return-type is initial.
        return-type = 'S'.
        return-message = documentnumber.
      endif.
    else.
      call function 'BAPI_TRANSACTION_COMMIT'
        exporting
          wait = 'X'.
      if sy-subrc = 0.
        return-type = 'S'.
        return-message = documentnumber.
      endif.
    endif.
  else.
    return-type = 'E'.
  endif.
But, it's not work too. So, I tried to commit at JCO code. Is there any kind of problem?
