Please help me how to move my data to the cloud

[Nandar Wai Yee]

Hello Masters,

I want a solution for my problem....

             The problem is that ..how to move my data to the cloud.
              I built an application.
              It is ok in local ...no error....it can show the result without any difficulty.
              But  after i deployed my application to the web,  my application can't work well as in local.
              I mean, when i put an input to the  input box, then i pressed calculate button, the result cannot be shown.
              How can i change which part of the code and where?
              I am waiting forward ur reply.

with best regards,

[Greg]

Please post the error message you get when you press the calculate
button. You can find this in the log, which is in the admin dashboard.

Without this information, no-one can help you.

Cheers
Greg.

Hi ,

Please go to your application dashboard on GAE and on the left hand  side you will see a link to your logs. You can have a look at the logs there and if you find any error you can post it here.

I wrote the source code as follows in dopost function that is in  one of the servlet classes
...............................

protected void doPost(HttpServletRequest req, HttpServletResponse resp)
            throws ServletException, IOException {
        Float fw=Float.parseFloat(req.getParameter("frmWeight"));
        Float fh=Float.parseFloat(req.getParameter("frmHeight"));
        Float bmi=(float)0;
        String type=req.getParameter("frmType");
        if(type.equals("lb/inches")){
            bmi=(fw*(float)703)/(fh*fh);
        }else if(type.equals("kg/m")){
            bmi=fw/(fh*fh);
        }
        String status=new String();
        if(bmi<=(float)18.5) status="Underweight";
        else if(bmi>(float)18.5 && bmi<=(float)24.9) status="Normal";
        else if(bmi>(float)25 && bmi<=(float)29.9) status="Overweight";
        else if(bmi>=(float)30 ) status="Obese";
       
        BMI myB=new BMI();
        myB.setBmi(bmi);
        myB.setHeight(fh);
        myB.setHistDate(new Date());
        myB.setUnit(type);
        myB.setWeight(fw);
        myB.setWeightStatus(status);
        myB.setPersonName((String)req.getSession().getAttribute("loginPKey"));
       
        BMIJDO myBmiJDO=new BMIJDO();
        myBmiJDO.saveNewEmployer(myB);
        List<BMI> l=myBmiJDO.getAll((String)req.getSession().getAttribute("loginPKey"));
        req.setAttribute("bmisize","1");
        req.setAttribute("histList",l);
        RequestDispatcher r=req.getRequestDispatcher("jsp/bmi_history.jsp");
        r.forward(req, resp);

Hi...allways catch an exception around constructs like Float.parseFloat(...)

The user could input wrong data that cannot be parsed into a Float, like your provided example 1,8.
1.8 (with dot) should work.
