Dynamic configurations on remote clients


Strategy 1:Use server to provide configuration:

Every client will have to use this configuration.
No per client configuration option.
Requires setting jvm params

Strategy 2: Send configuration file to client on default location.

Per client configuration possible
Strategy requires transmitting file to client.
Requires setting jvm params

Strategy 3: Build client handler looking for flags.

Per client configuration possible
Strategy requires building handler.
Not easy to add features later on.
Doesn't require jvm params

Key design rights:

Passing bits to individual client is key rather server side
Use the build-in logback handler is better rather building one.

Rationally:
passing logger:level is the possible, handler will look if logger are set and will use if found.
handler will reset all previous configuration.

Best solution: Key is pass the file.

This will be future proof
Works per client
Requires setting jvm params

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 ...
