what is Jboss FUSE - is it a container or framework ?

What is the difference between Jboss FUSE and Jboss EAP

[slayercode2]

Jboss EAP is an open source Java EE-based application server. Jboss FUSE is an open source Enterprise Service Bus (ESB) that uses Apache Karaf as container. There is another ESB developed by Redhat, named, Jboss Fuse Service Works, that offers more capabilities that Jboss Fuse (see, http://www.jboss.org/products/fsw/overview/). JBoss Fuse Service Works leverages the JBoss Enterprise Application Platform as it’s container, while JBoss Fuse uses Apache Karaf (OSGi) [http://blog.vizuri.com/jboss-fuse-vs.-fuse-service-works].

Thank you Akram

However i do have a few questions - if you could help with my doubts.

1) What is the difference between FUSE and Apache Camel  ?

2)If i can use apache camel direct in my Java Application and deploy this in Jboss EAP - In what case would I use camel with FUSE. ?

Example/User case would help.

thanks in advance

Hi

Apache Camel isn’t actually an ESB but some developers (included me) call Apache Camel a lightweight ESB because it supports many functionnalities provided by ESBs (e.g., the routing, transformation, orchestration).

The difference that Camel doesn’t have a container or a reliable message bus but it it can be deployed as well on an ESB such Jboss Fuse. In the case of JBoss Fuse Service Works ESB, it is possible to develop and to compose easily services which are developed using many technologies (beans, bpel, bpmn, camel, and so forth).

Here two links that compares Apache Camel with Servicemix ESB and with Mule ESB:

Thanks Akram

From your post I understand that Apache camel does not have a container and camel project can run by itself - If i can deploy camel project as a war in a jboss as or tomcat - in what case would I use FUSE or FUSE container. ?

Thanks.

It depends in your application requirements. In my case, I don't use Jboss Fuse and I use instead Jboss Fuse Service Works (FSW). The latter is an ESB that is based on the former ESB and offers more capabilities. Jboss FSW is dedicated for SOA applications. It regroups many tools, such BPMN, BPEL, Drools, JMS, Apache Camel, etc. It also provides many functionalities to facilitate the development of SOA applications, such interceptors, composers, transformers, etc. It also provides an graphical editor, named Switchyard, that helps to develop and visualize graphically your SOA applications.

So, if your application needs these functionalities and your complexity of integration is high, then the Jboss FSW can be efficient. Otherwise, you can use Apache camel to develop you applications.

Here an interesting article that describes the appropriate use cases for ESB and Apache Camel
