javax - query.list() Exception java.lang.Integer cannot be cast to java.lang.String -


i encounter error when i'm in javax queries far have not encountered such error , not know why

@post @path("/aa") @consumes(mediatype.application_json) public response polaki(user user, @headerparam("authorization") string authstring, @headerparam("api_key") string apikey) throws exception {     if (authstring.equals(usersetting.authorization) & apikey.equals(usersetting.api_key)) {         tx = session.gettransaction();          tx.begin();         query query = session.createquery("from service  service=:service");         query.setparameter("service", user.getservice());         tx.commit();         list ls= query.list(); // eror          return response.status(200).entity("{\"message\":\"service eror\"}").build();     } else {         return response.status(200).entity("{\"message\":\"service eror\"}").build();     } }

exception java.lang.integer cannot cast java.lang.string

what user.getservice() return? integer?

try example , see happens:

query.setparameter("service", string.valueof(user.getservice()));

service varchar (string-ish) in database.
