Learning MongoDB

I spent sometime to learn some basic stuff about MongoDB. I started searching internet and found some very helpful links.
Try the MongoDB online (interactive tutorial): http://try.mongodb.org/
Little MongoDB book (PDF) : http://openmymind.net/mongodb.pdf

After going through above links I got some confidence and I downloaded the MongoDB from http://www.mongodb.org/downloads .  Installing the db was very simple and within minutes I was having mongo up and running on my Macbook.

Then I thought of creating a sample spring application to learn spring integration with mongo. I followed the documentation at http://docs.spring.io/autorepo/docs/spring-data-mongodb/1.4.3.RELEASE/reference/html/index.html.

I created an application which fetches all users from the database. The code for the sample application is available at https://github.com/itsmanishagarwal/SpringMongoDb.

Anybody can download the code and use as per their need.

How to quickly setup ActiveMQ broker, publisher and subscriber

Last week I was working on an issue related to ActiveMQ messaging. During my debugging the most painful part was to start the entire application and then execute the test scenario just to test some functionality or feature in ActiveMQ. After spending some time I realized that to speed up my debugging and anaysis I have to create a separate application/program which I can start and stop quickly after making changes. So, I created two programs:
ActiveMQPublisherTest: This program start the ActiveMQ broker and then push messages into a queue.
ActiveMQSubscriberTest: This program listens to the ActiveMQ broker started by "ActiveMQPublisherTest" and receives the event published by it.

I have published the entire source code on GitHub at: https://github.com/itsmanishagarwal/ActiveMQTest

To use these programs you just need to change the XML files to point to your database.

Any suggestions or feedback is welcome.
