Internal Server Error [duplicate]

I am working on an SMS Sending application and for login purpose i want to send the username and password using POST method from my Android Application to the web server.

When I click on lo-gin button the application is not responding and the console prints the following message in response of the Post request.

HTTP/1.1 500 Internal Server Error

While my application running fine with the GET method.

I am not able to figure out why this is causing...

the whole code is here:

package com.vikas.httplogin;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.util.ArrayList;
import java.util.List;

import org.apache.http.HttpResponse;
import org.apache.http.NameValuePair;
import org.apache.http.client.ClientProtocolException;
import org.apache.http.client.HttpClient;
import org.apache.http.client.entity.UrlEncodedFormEntity;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.impl.client.DefaultHttpClient;
import org.apache.http.message.BasicNameValuePair;

import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.widget.TextView;

public class HttpLogin extends Activity {
    TextView tv;

    private static final String tag ="FATAL_ERROR";

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);        
        connecttoServer();
    }

    private void connecttoServer()
    {
        BufferedReader br = null;
        try
        {
            HttpClient client = new DefaultHttpClient();
            HttpPost request = new HttpPost("url of my site");

            List<NameValuePair> params = new ArrayList<NameValuePair>(3);

            params.add(new BasicNameValuePair("username","vikaspatidar"));
            params.add(new BasicNameValuePair("password", "patidar"));
            UrlEncodedFormEntity entity = new UrlEncodedFormEntity(params);

           request.setEntity(entity);

          Log.v(tag,request.getMethod().toString());
          HttpResponse response = client.execute(request);


           Log.v(tag, response.getStatusLine().toString());
            br = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));
            StringBuffer sb = new StringBuffer("");
            String line = "";
            String NL = System.getProperty("line.separator");
            while ((line = br.readLine()) != null) {
                sb.append(line + NL);
            }
            br.close();
            String result = sb.toString();
            Log.v(tag, result);


    } catch (ClientProtocolException e)
    {

        Log.v(tag, e.getMessage());
    }
     catch (IllegalStateException e) {

         Log.v(tag, e.getMessage());
    } catch (IOException e) {

         Log.v(tag, e.getMessage());
    }
    }
}

That's definitely looks like server-side error, not android problem. Look at server log files.

The way you're setting parameters to request looks weird, try setting parameters like this:

    HttpPost post = new HttpPost("url of my site");
    BasicHttpParams basicHttpParams = new BasicHttpParams();
    basicHttpParams.setParameter("username", "vikaspatidar");
    basicHttpParams.setParameter("password", "patidar");
    post.setParams(basicHttpParams);
    //...
