i am very new to ESB and i want to implement an ESB module which receives messages to ActiveMQ. Could you suggest me where i should begin. I have installed and got WSO2 and ActiveMQ working together. I am looking for a guide or some links which can help me get a good start at it.
thanks
This provides good set of samples on JMS with ActiveMQ.

I am a Java professional. I have a requirement to implement Enterprise Service Bus(ESB). There are quite a few ESB providers are available in the market.I am confusing a bit among those.
Please suggest which one is the best to implement ESB and BPM. I am expecting to have an open source solution with rich documentation and easy to understand with number of examples and scenarios so that we can start from scratch and implement it without any hassle.
Yes the number of options can be confusing. It's highly depends on your use case and what you're trying to achieve. Without much context, I can only share with you the recent tutorial I wrote around Bonita (A Bpm platform) and Apache Camel (A lightweight ESB): http://community.bonitasoft.com/blog/enhance-your-bonita-applications-apache-camel
In this tutorial, I explain how to trigger new process instances on new incoming emails event.
Cheers
WSO2 has a good option with their Enterprise Integratir. This combines ESB, BPM and related functionality.

However this is one of those questions that is purely opinion based.
I'm using Spring Integration with AMQP-backed messages and I'd prefer to use JSON instead of the default Java serialization for messages. This preference is due in part to serialization exceptions encountered when using Kotlin objects.
While researching the issue, I came across this post:
Spring integration - AMQP backed message channels and message conversion
So it seems the ability to use JSON serialization with AMQP-backed messages has only recently been supported. Moreover, I believe Spring Cloud Stream project provides support for this approach out-of-the-box but I haven't been able to figure out how to achieve something similar with SI.
I came across a post that provides a means to do this channel-by-channel but it seems tedious to configure it this way for each channel when I really just want to use it across the board.
Is there something preventing you from upgrading to 4.3?
<int-amqp:channel id="withEP"
extract-payload="true" message-converter="jackson" />
There's currently no way to globally set options for all channels of a particular type.
I want create a demo of an integration of ESB with the Adobe AEM. Even a very basic one will suffice. I need to understand if :
1. Is this is Possible/feasible?
2. How can one achieve this?
Please let me now if you have any questions.
Your question is a little broad.
What does "integration" mean in your context?
AEM ist built on Java Technology.
If your ESB provides a REST interface (or SOAP or RMI or JNI etc) you could access it in a component or a servlet etc.
You may want to look at this to get a clearer picture:

I've been doing Google around to find out the solution for the question "how can I change application integration style from point-to-point to a bus-bus in BizTalk ESB 2.0?".
Please could any one suggest me answer for this?
Place the ESB as HUB and Spoke among all the external applications.
I am getting started researching / creating a groovy portlet that will connect to a REST based ESB service that returns JSON; I will also need to pass the username in the headers. I was wondering if there are any examples out there on how to create the portlet and set the headers? I am new to groovy and from what I understand this can be accomplished rather easily. Essentially I want a portlet that will allow a user to search for a widget via a search box and return a list of matches. Not sure that it matters but the portlet will be deployed to the Vignette Portal. Any info would be much appreciated!
Thanks in Advance!
Doing a portlet with Java/Groovy is very doable with Spring Portlet MVC. I used some sample code from various sources a year ago but googling on it will give you more modern examples and let you pick something more applicable to your app. The real issue comes up with how you plan on building your app. Gradle is the best option for writing a Groovy web app.
However if you are talking about using Grails, then it becomes much more difficult and I would not advise learning Grails as you are trying to get it jammed into a 'portal' implementation. There are plugins for Liferay and 'portlets' in Grails but when I last looked at them earlier this year, they did not seem fully baked.
Calling REST based services with JSON or whatever from your server code doesn't have to care that you are in a 'portal'. The big issues comes up when you are trying to create the UI with your portal provider specific APIs. Don't be fooled into thinking you won't be using portal specific stuff. We used Liferay a bit and from my perspective the Portlet spec was very slim so to do much of anything interesting in a portal, you have to use some portal specific stuff, at least for UI and authentication services.
So my suggestion is build a Gradle Groovy Web project and use the Spring Portlet MVC Java examples to get something going and then you can simplify with Groovy as it makes sense. Initially you might want to simply start with Java if that is your comfort zone because integrating with your portal might be daunting enough without trying to learn a new language to boot.
