Problem sending HTTP post request in Java

Question

Hey, I'm trying to post an http request with xml body. This is my code:

public void setBla(String url, String cookie, SomeEnum status) {
    String availabilityUrl = url;
    HttpPost httpPost = new HttpPost(availabilityUrl + VERSION_TEXT);
    httpPost.setHeader(HttpHeaders.AUTHORIZATION, LP_AUTH_HEADER_VALUE);
    httpPost.setHeader(HttpHeaders.ACCEPT, MediaType.APPLICATION_XML);
    httpPost.setHeader("X-HTTP-Method-Override", HttpMethod.PUT);
    httpPost.setHeader("Cookie", cookie);
    httpPost.setHeader(HttpHeaders.CONTENT_TYPE, MediaType.APPLICATION_XML);
    HttpResponse response = null;

    try {
        HttpEntity entity = new StringEntity("<availability><chat>" + status + "</chat></availability>", HTTP.UTF_8);
        httpPost.setEntity(entity);
        response = m_httpClient.execute(httpPost);
    }
    catch (Exception e) {
        e.printStackTrace();
    }
}

Im getting a bad request from the AppServer (400), and in debug I can see that HttpEntity also has ContentType header and its set to text/plain... Why? What am I doing wrong? What is the right way to send a request with a body?

SOLUTION:

OK.. I got it.. Thanks skaffman, that was pretty close :) AbstractHttpEntity declare setContentType function...

Sorry for the bother..

its worth mentioning that you are using Apache http client library (and which version). — Omry Yadan

Assuming this is HttpClient 4.1, then you're not using the appropriate constructor for StringEntity, you probably need to specify the mime type as well as the charset, e.g.

HttpEntity entity = new StringEntity(xmlString, "application/xml", HTTP.UTF_8);

See javadoc.
