java - BadRequestException in JAX-RS endpoint -

i have following endpoint declared in jax-rs application:

@webservice public interface alertweb {     @post     @path("/add")     @produces(mediatype.application_json)     @consumes(mediatype.application_form_urlencoded)     public stringresponse addalert(string name,             int amount, string timespan, string repo, string action);  } 

i'm using following curl command call endpoint:

curl -x post -h "cache-control: no-cache"  -h "content-type: application/x-www-form-urlencoded"  -d "name=yellow&amount=2&timespan=day&repo=a&action=%7baction%3a'greendivaction'%2c+message%3a'simple+message'%2c+args%3a+%5b'arg1'%2c'arg2'%5d%7d" http://localhost:8080/adminservice/alert/add 

but keep getting following error when make request:

javax.ws.rs.badrequestexception: java.lang.numberformatexception: input string: "" 

note line breaks in curl syntax added readability.

what doing wrong?

you need add @formparam method parameters if want them injected such

@post @path("/add") @produces(mediatype.application_json) @consumes(mediatype.application_form_urlencoded) public response addalert(         @formparam("name") string name,         @formparam("amount") int amount,          @formparam("timespan") string timespan,          @formparam("repo") string repo,          @formparam("action") string action) { }
