JBoss Fuse is the name of the product from Red Hat.
Fuse ESB was the old name of the product, when it was FuseSource as the company.
Red Hat acquired FuseSource 2 years ago, and then renamed the product from Fuse ESB to JBoss Fuse.
So you should use JBoss Fuse.
JBoss Fuse 6.1 is the last release. We are currently working on JBoss Fuse 6.2, which is scheduled for release in early 2015.
Infact I realized it after posting this question. I have downloaded both versions, I can clearly see that JBOSS Fuse 6.1 has support for camel 12.x version, HawtIO inbuilt etc.. where Fuse ESB 7.x version has camel 2.9 version and no HawtIO etc.
So started working with JBOSS Fuse 6.1
Thanks you again..
