Acceder al xml de un servicio web

[coolz41]

Hola queria preguntaros como accedeis al xml de un servicio web, yo hasta ahora estoy usando httpclient pero me da errores de vez en cuando. Lo hago asi:

public class ObtenerXML {


public static String realizarAccion(String url) throws HttpException {

String responseBody = null;

// Create an instance of HttpClient.
HttpClient client = new HttpClient();
//client.getParams().setParameter("http.protocol.con tent-charset", "UTF-8");


// Create a method instance.
GetMethod method = new GetMethod(url);

// Provide custom retry handler is necessary
method.getParams().setParameter(HttpMethodParams.R ETRY_HANDLER,
new DefaultHttpMethodRetryHandler(3, false));
// method.getParams().setParameter("http.protocol.con tent-charset", "UTF-8");


try {
// Execute the method.
int statusCode = client.executeMethod(method);

if (statusCode != HttpStatus.SC_OK) {
System.err.println("Method failed: " + method.getStatusLine());
}

// Read the response body.
responseBody = method.getResponseBodyAsString();

// Deal with the response.
// Use caution: ensure correct character encoding and is not binary data


} catch (HttpException e) {
System.err.println("Fatal protocol violation: " + e.getMessage());
e.printStackTrace();
} catch (IOException e) {
System.err.println("Fatal transport error: " + e.getMessage());
e.printStackTrace();
} finally {
// Release the connection.
method.releaseConnection();
}

return ((responseBody));
}

}

Si conoceis alguna forma mas eficiente de hacerlo os lo agrdeceria.

Muchas gracias!!
