JAX-RS Boolean Parameter Type

[scardis <sc...@gmail.com>]

I have a method resembling the following:

@Path("/testBoolean")
@GET
public String getString(@QueryParam("value") Boolean value) {
    if (value != null) {
        return Boolean.toString(value);
    } else {
        return "No value";
    }
}

When I call this service with:
http://localhost:8080/test-rest/test/testBoolean

I receive the String "No Value" as the response (as expected).

However, when calling this service with either of the following two URLS:
http://localhost:8080/test-rest/test/testBoolean?value=true
http://localhost:8080/test-rest/test/testBoolean?value=1

I receive an XMLFault indicating "java.lang.IllegalArgumentException:
argument type mismatch".

What (if any) is the appropriate way (using JAX-RS) to pass a boolean type
argument as a QueryParam?  I realize that I could change the type to String,
but that would dirty my APIs for non-Rest clients.

I can't find anything in the JSR-311 specification, or the CXF documentation
discussing this.

Thanks -

Hi

I've definitely updated the code to convert parameters into objects of
classes which have constructors accepting String or have valueOf(String)
static methods...but the tests were a bit sloppy, so a minor patch have
been attached to ensure the QueryParams are also handled properly...

https://issues.apache.org/jira/browse/CXF-1543


So the code below should work as expected.
In JAX-RS you may also write

public String getString(@DefaultValue("No value") @QueryParam("value")
Boolean value) {
    return Boolean.toString(value);
}

But not in CXF though :-) it could be a nice little patch exercise, if
this feature is needed :-)

Cheers, Sergey
