I know that Apache Camel is java open source framework and Jboss Fuse is ESB which act like container to bind camel into its container . However i need to know its differences in some more depth .
Any help will be appreciated .
In simplified terms, camel framework is the set of api's (java code) which are used in system integration projects whereas fuse is the server like tomcat where code is deployed.
"JBoss Fuse combines several technologies like core Enterprise Service Bus capabilities (based on Apache Camel, Apache CXF, Apache ActiveMQ), Apache Karaf and Fabric8 in a single integrated distribution."
Deploy applications utilizing some different configurations and technologies is one of many qualities in Jboss Fuse.
"Camel" as being a rule based routing & mediation engine which can be used inside a full blown ESB, a message broker or a web services smart client. Though if you want to, you could consider that Camel is a small, lightweight embeddable ESB since it can provide many of the common ESB services like smart routing, transformation, mediation, monitoring, orchestration etc.
We should also mention what Camel isn’t. Camel isn’t an enterprise service bus complete(ESB ), although some call Camel a lightweight ESB because of its support for routing, transformation, monitoring, orchestration, and so forth. Camel doesn’t have a container or a reliable message bus, but it can be deployed in one, such as Open-ESB or ServiceMix. For that reason, we prefer to call
Camel an integration framework rather than an ESB.

I want to use an embedded http server in my enterprise apps (and move away from standalone containers) and was expecting Tomcat to provide an implementation. I was assuming Sun, Jetty and Jersey's implementations cannot support enterprise load.
But looking at Tomcat, I see no way to run REST apps that use JAX-RS, only servlets. So my questions are:
Will use of com.sun.net.httpserver.HttpServer work in a production environment, or do I need another library?
Am I understanding correctly the boundary between JAX-RS embedded servers and servlet containers (maybe that will explain why Tomcat doesn't provide such a server)
Other notes:
I do not want to use Spring unless that's the only choice
I want to ask about JBoss Middleware for ISO8583.
So, I kinda new on ISO8583, from what I know is we could use JPOS framework for this one. Then my supervisor ask me to research about JBoss Middleware that could be used to develop middleware application for send, receive, and parse ISO8583 message.
I have read on JBoss Middleware website, unfortunately I'm still not sure which JBoss technology should I use to develop such application.
Here is my questions:
1. In order develop enterprise application that capable to send, receive, and parse ISO8583, should I combine JPOS with JBoss Middleware? or JBoss Middleware has a complete capability to handle it?
2. Does anyone has/know good material/tutorial for me to learn about building ISO8583 middleware with JBoss technology?
Thank you.
JBoss Middleware is a family of products and its components alone do not provide ISO8583 capabilities out of the box.
jPOS is one of the most popular Java frameworks that provide complete capabilities to handle sending and receiving ISO8583 messages. There are other alternatives such as j8583 and IsoTypes.
You can combine any of these ISO8583 libraries together with JBoss Fuse (part of the JBoss Middleware family) to build a solution capable of sending, receiving and parsing ISO8583 messages.
I'm not aware of a definitive guide about building such solutions. If you need to use JBoss Middleware, you can follow this route:
Look into IsoTypes, which provides an ISO8583 marshalling library for Apache Camel (used by JBoss Fuse).
Start by building a Camel route that implements the IsoType library functions. Look into this sample project.
Please, be aware that building a production ready ISO8583 server and/or client from open source solutions require significant work in terms of scalability, information security and compatibility with multiple financial hosts and switches.
My answer only refers to the first basic steps to understand your problem/solution fit a bit better.
As a side note, you may be interested in looking at jreactive-8583, an ISO8583 connector that handles message parsing and the network layer out of the box. You may build your application using this and deploy it into JBoss Application Server (part of the JBoss Middleware family too). I use it in production.
You can take advantage of JPos Q2 and create a servlet deployable to JBoss container.
In the service init method you can do this:
Q2 q2 = new Q2();
q2.start();
Using Mule ESB I noticed that you can connect (via anypoint connectors) applications, databases, web services etc.
Since I am making a comparison between different ESB (Enterprise Service Bus) I ran into WSO2 ESB and reading the documentation it seems that allows to interact only web services (through SOAP communications).
Someone confirms what I wrote? Or WSO2 ESB is flexible as Mule ESB and I'm wrong (if so what are the differences)?
WSO2 ESB also has the concept of connectors which you can use to connect to external applications, databases, file systems and web services hosted in cloud or in internal networks. Here is a webinar which you can follow to get more information.
http://wso2.com/library/webinars/2014/09/esb-connectors-for-on-premise-and-cloud-integration-solutions/
I can't help as my knowledge of WSO2 is limited. What I could do is to recommend you the book open source ESB in action, although outdated its data, the introduction is amazing and the comparison methodology is also good. You could follow the same approach with the state of the art today.
Most of the connectivity to applications, databases, different protocols are already available with wso2 ESB and wso2 product stack out of the box. However there are some connectors that will support integration with on-premises legacy systems and additional protocols. eg: ejb, is08583, kafka, etc.
I would like to avoid dependency on ActiveMQ. Is there a way to make JBossFuse to use WebSphereMQ ? (I'm assuming activeMQ is required for framework to run - internal dependency)
The description on jboss fuse site reads like..
Core messaging is provided by Apache ActiveMQ, services framework (SOAP, XML/HTTP, RESTful HTTP)...
PS:
Arguements like "it would be innefficient, expensive" etc, need not be considered at this stage. Reason for prefering WebSphereMQ is beyond my control.
No you can use JBoss Fuse without ActiveMQ at all. For example the minimal distribution does not come with AMQ pre-installed.
JBoss Fuse allows you to slice and dice what you want pre-installed.
If you want to use WebSphereMQ then you can do that, though that would be under the assumption that WebSphereMQ as a server is running in another JVM / box. And that JBoss Fuse would act as a client to that broker. If so you can install the WebSphereMQ Java Client JARs in Jboss Fuse and use that.
We are currently using JMS queue in Weblogic.
Can we use same JMS queue in Websphere as part of weblogic to websphere migration.
Is there any other concept available in websphere which can replace JMS queue?
WebSphere Application Server has a built-in JMS provider, due to the Java EE standard which defines it as mandatory (as Arjan Tijms already stated).
Setting up the JMS provider requires a so called Service Integration Bus, which is a simple Messaging Bus inside WebSphere. The Service Integration Bus also allows to setup High Available JMS queues/topics when using WebSphere Application Server Network Deployment.
Using this queues/topics outside of a WebSphere context - by putting messages into the queues from external clients or reading them from external clients - is hard.
Mainly due to the WebSphere internal CORBA communication it is quite tricky to setup a working and stable
configuration - and you need to know some internal WebSphere tricks.
My recommandation is to use internal jms configuration only for applications which are deployed on the same WebSphere Application Server-Configuration.
If you really need external access to the JMS queues/topics, you should write a adapter to access it.
This blog post describes in detail how to setup a simple WebSphere internal JMS configuration.
WebSphere has indeed an internal JMS provider. It's accessed using the SIB (Service Integration Bus). See http://www.packtpub.com/article/messaging-with-websphere-application-server-7.0-part1
WepSphere has JMS queues as well. Are you wanting to have the queue running within WebSphere, or are you trying to point to a queue running elsewhere?
Yes, you can.
Configuration depends on your JMS System.
If your JMS Middleware is running external like ApacheMQ or Swift JMS, you can normally install an Resource Adapter and then use that specific configuration (at least for the Jms configuration). Then you can use Websphere's JMS Configuration (like Queues and Topics) and therefor your normal MDB configuration.
Besides ActivationSpec (like above) at least with Websphere MQ you could use Listener Ports. I don't know if Listener Ports are available for other JMS Products.
If you want to use a built in Messaging System, you can use SIB I guess.
So plenty of options depending on your System.
A JMS provider is mandated by the Java EE specs so every application server has an inbuilt JMS Provider.
You have to make the right calls about your application needs. There might be valid reasons to use an external JMS provider such as WebSphere MQ.
