  1.   

    我看了下，好像是这段代码返回的值有问题。// 保存提交内容
    public String SaveSubmitInfo(String submitID,String personID,String mtelNo,String shopID,String shopName,String cusName,
    String callID,String subID,String recorder,String submitType,String submitMemo){
    DBGetResult dbgr = new DBGetResult();
    if(submitID.equals("")) return "0";
    try{
    dbgr.openConn();
    Calendar time=Calendar.getInstance();
    String tmpSubmitID = "";
    tmpSubmitID = "S" + String.valueOf(time.get(Calendar.YEAR)) + String.valueOf(time.get(Calendar.MONTH)) + String.valueOf(time.get(Calendar.DAY_OF_MONTH));
    if(submitID.length()==1){
    tmpSubmitID += "000" + submitID;
    }else if(submitID.length()==2){
    tmpSubmitID += "00" + submitID;
    }else if(submitID.length()==3){
    tmpSubmitID += "0" + submitID;
    }else{
    tmpSubmitID += submitID;
    }
    String strSql = "insert into SD_SvrSubMit(ID,CallID,SubID,CustomerID,PersonID,ANI,Recorder,SubMitInfo,SubMitTm,SubMitType,PersonName)values('"
    + tmpSubmitID + "'," + callID + "," + subID + ",'"+ shopID +"','" + personID + "','"+ mtelNo +"','"
    + recorder +"','"+ submitMemo +"',getdate(),'"+ submitType +"','"+ cusName +"')";
    dbgr.execSQLCmd(strSql);
    return "1";
    }catch(Exception ex){
    ex.printStackTrace();
    return "0";
    }
    finally{dbgr.closeConn();}}
    %>

    jsp 有空指针异常，建议用火狐浏览器调试...
