Blackberry: Custom Popup Screen[Forgot Password Example]

Here I am providing one example that shows how we customize our Popup Screen. We can use this like a popup Screen or Dialog Screen. 
Below link is the Example for the Custom Popup Screen and I am showing an example of Forgot Password. 

In this you will get again two custom classes. Like, PictureBackgroundButtonField and CustomTextField where we can use images directly to the buttons and text fields. 
It will look like the below image:

Lets try this one. 
Feel free to ask questions.

Blackberry: Post Data Using JSON Object

We can post the data by the JSON format. 
For this first,
1. We have to take all the keys and values in One Hash table or Array of Hash tables(Vector)
2. Convert it into JSON object.
3. Send to server.
packagecom.alishaik.thread;
importjava.io.InputStream;
importjava.io.OutputStream;

    privateInputStream inputStream;
    privateStringBuffer stringBuffer=newStringBuffer();
    privateHashtable hashTable;
    privateString URL="";
    privateintindex=0;
     
      
    public PostDataThread(String url, Hashtable hash,intindex) 
    {
//      System.out.println("=========WEB SERVICE===========: "+url);        
        URL=Utility.escapeHTML(url)+CommonMethods.updateConnectionSuffix();//interface=wifi; or deviceside=false;
        this.index=index;
        this.hashTable=hash;//Here I am taking one Hashtable. You can manage according to your requirement.
    }
     
    publicvoidrun() 
    {
        try
        {
            httpConnection=(HttpConnection)Connector.open(URL);
            httpConnection.setRequestMethod(HttpConnection.POST);
             
            URLEncodedPostData oPostData =newURLEncodedPostData(URLEncodedPostData.DEFAULT_CHARSET, false);
            oPostData.setData(provideJSONObject());//IMPORTANT
             
            byte[] postBytes = oPostData.getBytes();
            httpConnection.setRequestProperty(HttpProtocolConstants.HEADER_CONTENT_TYPE,"application / requestJson");
            httpConnection.setRequestProperty(HttpProtocolConstants.HEADER_CONTENT_LENGTH, Integer.toString(postBytes.length));
            
            OutputStream strmOut = httpConnection.openOutputStream();
            strmOut.write(postBytes);
            strmOut.flush();
            strmOut.close();
             
            intresponse=httpConnection.getResponseCode();
            if(response==HttpConnection.HTTP_OK)
            {
                inputStream = httpConnection.openInputStream();
                intc;
                while((c=inputStream.read())!=-1)
                {
                    stringBuffer.append((char)c);
                }                   
                parseData(stringBuffer.toString());             
            }
            else
                parserInterface.didFailParser("Connection failure HTTP Response: "+response);
        }
        catch(finalException e)

                msg="No Data Found";
            //Show failure alert here
        }
        finally
        {
            try
            {
                if(httpConnection!=null)
                    httpConnection.close();
                if(inputStream!=null)
                    inputStream.close();
            
            catch(Exception e2) 
            {}          
        }
    }
     
    private String provideJSONObject()
    {
        try
        {
            JSONObject jsonObj=newJSONObject();
            jsonObj.put("data", hashTable);//Getting correct data; You can check here
//          System.out.println("======================JSON STRING FOR POSTING: "+jsonObj.toString());
            returnjsonObj.toString();
        
        catch(Exception e) 
        {
            returnnull;
        }
    }
     
    private void parseData(String responseString) 
    {
        responseString="["+responseString+"]";
        System.out.println("======================\n\n"+responseString+"\n\n===================");
        //Do what you want.        
    }
}
and the method for Utility.escapeHTML(url) is:

public static String escapeHTML(String s)
{
               StringBuffer sb = new StringBuffer();
               int n = s.length();
               for (int i = 0; i < n; i++) {
                     char c = s.charAt(i);
                      switch (c) {
                                           case ‘ ‘: sb.append(“%20″); break;
                                         default: sb.append(c); break;
                     }
             }
            return sb.toString();
}
