how to set href to outter website programatically?

I'm generating html page programatically.

I have an href with this src

"https:/www.w.com/editor/?lon=-72.382769&lat=41.324657"

however when i generate the html like this:

private Span getEditorSpan(CompleteRoutingResponseShort response) {
    Span span4 = new Span();
    for (int i = 0; i < response.alternatives.size(); i++) {
        String editorUrl = editorUrlGenerator
                .generateUrl(response.alternatives.get(i).response.results);

        A a3 = new A();
        a3.appendText("alt " + i);
        a3.setTitle(response.alternatives.get(i).alternative_regression_id);
        a3.setHref(editorUrl);

        span4.appendChild(ImmutableList.of(a3, new Span().appendText("&nbsp&nbsp&nbsp")));
    }
    return span4;
}

the result is an href that directs to:

"http://localhost:63342/https:/www.w.com/editor/?lon=-72.382769&lat=41.324657"

this is the resulted html:

<span><a title="358_0" href="https:/www.w.com/editor/?lon=-71.18612999999999&amp;lat=42.21286&amp;zoom=4&amp;segments=63385498,76487105,22543109,22503638,22527613,76599462,76599461,76599460">alt 0</a><span>&nbsp;&nbsp;&nbsp;</span></span>

how can I make the url direct outside my localhost domain?

this is my url builder:

    UriBuilder builder = UriBuilder
            .fromPath(Constants.EDITOR_BASE_URL)
            .scheme("https");

    builder.queryParam("lon", firstPath.x)
            .queryParam("lat", firstPath.y)
            .queryParam("zoom", 4)
            .queryParam("segments", segmentsInUrl);


    return builder.build().toString();

Solution

The protocol set in your URL is https:/ and not 'https://'. This causes the application to think it is a relative URL. Fix this problem and it shouldn't prepend the domain name http://localhost:63342 afterwards.
