We have a entire integrations system that is based on jboss esb (jboss-5.1.0.GA).  Basically we use it to monitor different directories.  When a new file comes in jboss picks it up and starts processing it.  

What is the current software that is used to do this type of thing?  I see references to switchyard and jboss fuse but it looks like they are deprecated now also.

Any recommendations would be helpful.  Thanks
