DELETE giving 405 in postman - postman

Question

I am new to restful webservices and following java restful api tutorials.
all the HTTP requests are working fine except the DELETE request.
i am facing the same issue as described in this link.
REST - HTTP Status 405 - Method Not Allowed
also , in the predefined header values postman is showing
allow →GET,OPTIONS,PUT(image link is below)
i am following the correct syntax and url format as per the specification(pasted in image) but delete is not working.
allowed : GET,OPTIONS,PUT.img
please let me know where i am missing.

except delete other requests are working fine.
on sending DELETE the server is returning HTTP -405 method not allowed.
also on sending delete request then in the header values postman is showing
allow →GET,OPTIONS,PUT
Thanks

Make sure you do not have any URL Parameters entered in Postman, also make sure you do not pass any headers in postman.
The delete request should be plain without and of these.
Also, the string message ID need to be put in curly brackets. That would be the reason for your 405 mostly.
Change path annotation as below and try.
#Path("/{messageId}")
