Txtweb development steps:

Txtweb is a sms based platform, means that you can get everthing simply messaging to 92665 92665.

Format: @kilometre source destination

Eg: @kilometre chennai bangalore

send the above formatted message to 92665 92665 (No additional charge, but ensure you have put sms pack already)

Then it will reply like “Distance: 346 km Time: 5 hours 15 mins”.

Step 1: Create a account in txtweb (www.txtweb.com). Login to txtweb and click “create a new service” and reserve the keyword. After creating the keyword they will give “App key”.

The given App key will be used in the below dictionary program (refer the program – bold content).

Step 3: Create a File -> New -> Web Application Project

Project Name: Dictionary

Package: com.ngdeveloper.com

and paste the below code,

[java]
package com.ngdeveloper.com;

import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.http.*;
import java.util.ArrayList;
import java.util.List;
import org.jsoup.Jsoup;
import org.jsoup.nodes.Document;
import org.jsoup.nodes.Element;
import org.jsoup.select.Elements;

@SuppressWarnings("serial")
public class DictionaryServlet extends HttpServlet {

private static final String APPKEY_NAME = "txtweb-appkey";
private static final String APPKEY_CONTENT = <strong>"2a129c1c-ac5a-48eb-962a-985a3f93828f"</strong>;

public void doGet(HttpServletRequest req, HttpServletResponse resp)
throws IOException {
processRequest(req, resp);
}

public void doPost(HttpServletRequest req, HttpServletResponse resp)
throws IOException {
processRequest(req, resp);
}

public void processRequest(HttpServletRequest request,
HttpServletResponse response) {
String txtWebResponse = null;
String txtWebMessage = request.getParameter("txtweb-message");

if (txtWebMessage == null || txtWebMessage.isEmpty()) {
txtWebResponse = getWelcomeMessage();
sendResponse(response, txtWebResponse);
return;
}

String[] parameters = txtWebMessage.split(" ");
if (parameters.length != 1) {
txtWebResponse = getWelcomeMessage();
sendResponse(response, txtWebResponse);
return;
}
txtWebResponse = "";
// String searchWord = URLEncoder.encode(parameters[0], "UTF-8");
// String sourceUrlString="http://en.wiktionary.org/wiki/" + searchWord;
String input_name = parameters[0];
try {
String url = "http://www.mydictionary.net/english/?word="+input_name+"";
Document document = Jsoup.connect(url).get();
Elements india = document.select("tbody").select("tr").after("td");
List mylist = new ArrayList();
for (Element answerer : india) {
mylist.add(answerer.text().toString());
}
String first = (String)mylist.get(4);
//String second = (String)mylist.get(5);
txtWebResponse = first+" \n";

} catch (Exception e) {

txtWebResponse = "Sorry, Try again with different words";
}

if (!txtWebResponse.isEmpty()) {
sendResponse(response, txtWebResponse);
return;
}

txtWebResponse = getNothingFoundMessage(txtWebMessage);
sendResponse(response, txtWebResponse);
return;
}

private void sendResponse(HttpServletResponse response, String smsResponse) {
try {
PrintWriter out = response.getWriter();
String smsResponse1 = "<html><head><title>Dictionary TxtWeb!</title>"
+ "<meta http-equiv=’Content-Type’ content=’text/html; charset=UTF-8′ />"
+ "<meta name=’" + APPKEY_NAME + "’ content=’" + APPKEY_CONTENT + "’ />"
+ "</head><body>" + smsResponse + "</body></html>";
out.println(smsResponse1);
} catch (IOException e) {

}
}

private String getWelcomeMessage() {
return "<html><body>Welcome to Dictionary \n\n"
+ "Reply with your search keyword.\n\n"
+ "(Powered by Intuit TxtWeb and Wiktionary)</body></html>";
}

private String getNothingFoundMessage(String txtWebMessage) {
return "<html><body>No word found: "
+ txtWebMessage + "\n\n"
+ "Reply with your search keyword.\n\n"
+ "(Powered by Intuit TxtWeb and Wiktionary) )</body></html>";
}
}
[/java]

Step 4: Right click on the project Run As -> Web Application

Then open the internet explorer and type this address “http://localhost:8888/”. Now you will be able to see the project.
