访问SAP的RFC

.NET

环境
Xp(sp3) vs2010, win2003 EN 32bit(sp2)
winform,webform

引用sapnco.dll,sapnco_utils.dll(自动引用）
配置文件需要改成混合模式

 Java

使用JCO,jco里面有4个版本，需要选择正确的版本，测试Jco是否正确可以使用 java -jar d:\jco\sapjco3.jar ，如果没有报错表示正常了

 public static List<String> callRfcExample() {
        // 获取RFC 对象
        JCoFunction function = RfcManager.getFunction("xxxx_V1");
        // 设置import 参数
        JCoParameterList importParam = function.getImportParameterList();
        importParam.setValue("I_WERKS", "www1");

        JCoTable tablename = function.getTableParameterList().getTable("R_GSTRP");
        tablename.deleteRow();
        tablename.deleteAllRows();
        tablename.clear();
        tablename.firstRow();

        tablename.appendRow();
        tablename.firstRow();

        tablename.setValue("SIGN", "I");
        tablename.setValue("OPTION", "BT");
        tablename.setValue("LOW", "2013-06-25");
        tablename.setValue("HIGH", "2013-06-25");
        // 执行RFC
        RfcManager.execute(function);

        // 获取RFC返回的字段值
//        JCoParameterList exportParam = function.getExportParameterList();
//        String exParamA = exportParam.getString("field_A");
//        String exParamB = exportParam.getString("field_B");
        // 遍历RFC返回的表对象
        List<String> list=new ArrayList<String>();

        JCoTable tb = function.getTableParameterList().getTable("ZAFKO");
        for (int i = ; i < tb.getNumRows(); i++) {
            tb.setRow(i);
            list.add(tb.getString("ORDER_NUMBER"));
            System.out.println(tb.getString("ORDER_NUMBER"));
            //System.out.println(tb.getString("field02"));
        }
        return list;
    }

另外win2003,32或64 bit的需要安装对应的
Microsoft Visual C++ 2005 Service Pack 1 Redistributable Package (KB973544)
话说win2003,32bit上安装了七把次都没成功:(
