  • So I cannot pass List as parameter? If not, How am I supposed to pass this value? Can you please tell me how? – Jenny Jul 05 '15 at 00:22
  • As [the Jersey documentation](https://jersey.java.net/documentation/latest/jaxrs-resources.html#d0e2153) states, as well as the linked answer, the type of the List element needs either a single String argument constructor or a `valueOf(String)` or `fromString(String)` method - Map has neither of these. Please explain what exactly you want to pass to the method. – Roman Vottner Jul 05 '15 at 00:36
