Hello, I've written a Web Script that performs a query and returns the set of results in JSON.

I've noticed that every time I execute the web script, the following warning message is written in alfresco.log:

21-lug-2008 17.13.28 org.apache.commons.httpclient.HttpMethodBase getResponseBody
WARNING: Going to buffer response body of large or unknown size. Using getResponseBodyAsStream instead is recommended.

What does it mean, in detail?

This relates to the HttpClient code used. (See HttpClient Apache project for more general info).
The call HttpMethod.getResponseBody() returns a byte[] and given that the reponse could be of substantial length it's advised that you stream the output of the response using HttpMethod.getResponseBodyAsStream() - this way you can read a user defined number of bytes. e.g.

BufferedReader reader = 
    new BufferedReader(new InputStreamReader(method.getResponseBodyAsStream())); 
StringBuilder result = new StringBuilder();
char[] buffer = new char[4 * 1024];
int charsRead;
while ((charsRead = reader.read(buffer)) != -1) {
    result.append(buffer, 0, charsRead);
}
reader.close();

This is covered in the HttpClient docs.
