Re: [Resteasy-developers] Verifying @QueryParam existence

[Bill B. <bb...@re...>]

There's two ways to do this:

@PUT
public void put(@Context UriInfo uri)
{
    boolean exists = uri.getQueryParameters().containsKey("doTest");
}

@PUT
public void put(@QueryParam("doTest") @DefaultValue("NOT EXISTS") String 
doTest)
{
    boolean exists = !"NOT EXISTS".equals(doTest);
}
