Getting Conflicting URI templates errors when trying to add resource class - rest

Question

I have a restfull implementation using Jersey and Tomcat7. I have 3 resources called RegionService, ClientService and NoteService defined in my campher.rest package.
When I try to add another resource called TestResource, and Tomcat starts, it gives me the following error below. I don't understand how /{notes} conflicts with /{test}??
Please help, my hair will thank you.

Answer 1

#Path("test")
will match <web-root>/test
#Path("{test}")
will match <web-root>/foo and <web-root>/bar. The word test here is merely the path-param map key to associate foo and bar values.
Notice the presence and absence of {} around the names. They completely change the meaning of the expression. Their presence indicates that you want to extract that out and put it in an instance variable annotated with #PathParam("name-between-brackets").
Your #Path("{test}") and #Path("{notes}") both are essentially asking Jersey to look for root URLs of the form http://<host:port>/<webapp>/{capture-text} and copy the capture-text into test and notes path variables respectively. This is ambiguous.
