Rome is a very simple Java API for reading RSS Feeds and is available under Apache License 2.0

Rome Home Page
https://rome.dev.java.net/

If you are a maven user just add this dependency

        <dependency>
            <groupId>rome</groupId>
            <artifactId>rome</artifactId>
            <version>1.0RC2</version>
        </dependency>

if you are using ant
  1. Add Rome jar from https://rome.dev.java.net/dist/rome-1.0.jar
  2. Add JDOM jar from http://www.jdom.org/dist/binary/archive/jdom-1.0.zip

And here is the code to pull feeds, 

import java.net.URL;
import java.util.List;
import com.sun.syndication.feed.synd.SyndEntry;
import com.sun.syndication.feed.synd.SyndFeed;
import com.sun.syndication.io.SyndFeedInput;
import com.sun.syndication.io.XmlReader;

public class App {
    public static void main(String[] args) throws Exception {
        String url = "http://rss.cnn.com/rss/cnn_topstories.rss";
        URL feedUrl = new URL(url);
        SyndFeedInput input = new SyndFeedInput();
        SyndFeed feed = input.build(new XmlReader(feedUrl));
        for (SyndEntry entry : (List<SyndEntry>)feed.getEntries()) {
            System.out.println(entry.getTitle());
        }
    }
}

Checkout SyndEntry  API doc

It was that simple just instantiating SyndFeedInput and SyndFeed

Access multiple Databases in JPA

According to JPA specification we can define multiple "persistence-unit" elements (i.e. like below) in persistence.xml file and can easily refer them inside Dao layers as this. public class PolarDaoImpl {     @PersistenceContext(unitName="PolarPU")     protected EntityManager entityManager; -- } public class BearDaoImpl {     @PersistenceContext(unitName="BearPU")     protected EntityManager entityManager; -- } Checkout sample persistence.xml <?xml version="1.0" encoding="UTF-8"?> <persistence version="2.0" xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd">     <!-- Database 1 -->     <persistence-unit name="PolarPU" transaction-type="RESOURCE_LOCAL">        ...

Validating CSV Files

What is CsvValidator ?   A Java framework which validates any CSV files something similar to XML validation using XSD. Why should I use this ?   You don't have to use this and in fact its easy to write something your own and also checkout its source code for reference. Why did I write this ?   Some of our projects integrate with third party application which exchanges information in CSV files so I thought of writing a generic validator which can be hooked in multiple projects or can be used by QA for integration testing. What is the license clause ?   GNU GPL v2 Are there any JUnit test cases for me checkout ?  Yes,  source How to integrate in my existing project ? Just add the Jar which can be downloaded from here  CsvValidator.jar  and you are good. Instantiate  CsvValidator c onstructor which takes these 3 arguements          // filename is the the file to be validated and here ...
