JAX-RS Path with count regular expression

If I use the "{}" to specify the count condition in the regular expression of JAX-RS @Path, eclipse throws as error.

@Path("/apps/{itemId:\\d{10}}")
public Response getItems(...

The @Path annotation value '/apps/{itemId:\d{10}}' is invalid: missing '{' or '}'.

Is above JAX-RS Path not a valid path ? Is it due to eclipse JAX-RS validator problem ? If I just specify @Path("/apps/{itemId}") there is no error.

You can't use curly brackets inside variable when using regex in Path annotation. Use instead:

@Path("/apps/{itemId: \\d+}")

regex = *( nonbrace / "{" *nonbrace "}" ) ; where nonbrace is any char other than "{" and "}"

Theoretically you can check 10 digits as you want using multiple [0-9]:

@Path("/apps/{itemId: [0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9]}")
