1.下载jco，将里边的文件拷贝到lib目录，下载地址http://download.csdn.net/source/2539321

2.将里面的两个dll文件拷贝到system32

3.编写如下代码

public List<RRSInvVO> getRRSInvFromSAP(String beginPlant, String endPlant,
   String year, String week) throws Exception{
  // 日日顺库存
  List<RRSInvVO> rrsInvs = new ArrayList<RRSInvVO>();
  JCO.Client mConnection = null;
  JCO.Repository mRepository = null;
  try {
   /**
    * 测试
    */
   //mConnection = JCO.createClient("客户端编号", "用户名", "密码",
   //  "语言", "服务器地址", "服务器编号");
   mConnection.connect();
   JCO.Function function = RRSInvImpl.createFunction(
     "接口名", mRepository, mConnection);

   //设置输入参数
   JCO.ParameterList input = function.getImportParameterList();
   if (beginPlant != null) {
    input.setValue(beginPlant, "BEGIN_WERKS");
   }
   if (endPlant != null) {
    input.setValue(endPlant, "END_WERKS");
   }
   mConnection.execute(function);

   //获取输出参数
   JCO.Table flights = function.getTableParameterList().getTable(0);
   RRSInvVO rrsInv = null;
   for (int i = 0; i < flights.getNumRows(); i++) {
    flights.setRow(i);
    rrsInv = new RRSInvVO();
    rrsInv.setCharg(flights.getString("CHARG"));
    rrsInv.setClabs(flights.getDouble("CLABS"));
    rrsInv.setClabs1(flights.getDouble("CLABS1"));
    rrsInv.setGmms_xgy(flights.getString("GMMS_XGY"));
    rrsInv.setLgort(flights.getString("LGORT"));
    rrsInv.setMaktx(flights.getString("MAKTX"));
    rrsInv.setMatkl(flights.getString("MATKL"));
    rrsInv.setMatnr(flights.getString("MATNR"));
    rrsInv.setMenge1(flights.getDouble("MENGE1"));
    rrsInv.setMenge2(flights.getDouble("MENGE2"));
    rrsInv.setOmeng1(flights.getDouble("OMENG1"));
    rrsInv.setOmeng2(flights.getDouble("OMENG2"));
    rrsInv.setSpart(flights.getString("SPART"));
    rrsInv.setVtext(flights.getString("VTEXT"));
    rrsInv.setWeek(week);
    rrsInv.setWerks(flights.getString("WERKS"));
    rrsInv.setWgbez(flights.getString("WGBEZ"));
    rrsInv.setYear(year);
    rrsInvs.add(rrsInv);
   }
  } catch (Exception ex) {
   ex.printStackTrace();
   System.exit(1);
   throw ex;
  } finally {
   if (mConnection != null)
    mConnection.disconnect();
  }
  return rrsInvs;
}
