      Design the order of registered modules in a way so that @Provider classes are bound before the resources that use them.

      Design the order of registered modules in a way so that @Provider classes are bound before the resources that use them.

      Parameter converters are not found, during resource factory initialization, if bindings are not strictly ordered.

      Example:

      • Resource R uses type T as QueryParam or PathParam
      • Type T does not have a constructor with String parameters or valueOf(String) method
      • ParamConverter C is can convert from String to T and vice versa and is defined via a ParamConverterProvider P

      If the binding order is

      1. bind(P.class)
      2. bind(R.class)

      everything works just fine, but, if the resource class is bound before the converter provider, the standard exception regarding missing conversion information is shown

      java.lang.RuntimeException: Unable to find a constructor that takes a String param or a valueOf() or fromString() method for javax.ws.rs.QueryParam("<paramName>") on public <className>.<methodName>(<methodParams>) for basetype: <typeName>
