Hi Friend,

Try the following code:

1)properties.jsp:

<form method="post" action="create.jsp">
<table>
<tr><td>Enter File Name:</td><td><input type="text" name="f">.properties</td></tr>
<tr><td>Enter Key:</td><td><input type="text" name="key"></td></tr>
<tr><td>Enter Value:</td><td><input type="text" name="value"></td></tr>
<tr><td></td><td><input type="submit" value="Submit"></td></tr>
</table>
</form>

2)create.jsp:

<%@page import="java.io.*,java.util.*"%>
<%
String str = request.getParameter("f");
System.out.println(str);
if(!str.equals(null)){
    try{  
        Properties p = new Properties();
        File file=new File("C:/"+str+".properties");
         p.store(new FileOutputStream(file),null);
          String key = request.getParameter("key");
          String val = request.getParameter("value");

          p.setProperty(key, val);
           p.store(new FileOutputStream(file),null);
          System.out.println("Operation completly successfuly!");
        }

    catch(IOException e){
    System.out.println(e.getMessage());
    }
}
 %>

Thanks

Below is a simple code package com;

import java.io.FileInputStream; import java.io.FileNotFoundException; import java.io.IOException; import java.util.Properties;

public class PropertiesFile { static Properties prop;

public PropertiesFile() throws IOException {

    prop = new Properties();
    FileInputStream filestream = null;
    try {
        filestream = new FileInputStream("E://Selenium//workspace//Sample Test//src//com//sample1.properties");
    } catch (FileNotFoundException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    prop.load(filestream);
}
public static void main(String[] args) {
    // TODO Auto-generated method stub
    try {
        PropertiesFile sp= new PropertiesFile();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    String name= prop.getProperty("name");
    System.out.println(name);
}

}
