Problem with Solr 4.0-ALPHA and JSON response

[Federico Valeri <fe...@gmail.com>]

Hi all, I'm new to Solr, I have a problem with JSON format, this is my Java
client code:

PrintWriter out = res.getWriter();
res.setContentType("text/plain");
String query = req.getParameter("query");
SolrServer solr = new HttpSolrServer(solrServer);
ModifiableSolrParams params = new ModifiableSolrParams();
params.set("qt", "/select");
params.set("q", "contenuto:(" + query + ")");
params.set("hl", "true");
params.set("hl.fl", "id,contenuto,score");
params.set("wt", "json");

QueryResponse response = solr.query(params);
log.debug(response.toString());
out.print(response.toString());
out.flush();

Now the problem is that I recieve the response but it doesn't trigger the
javascript callback function.
I see "wt=javabin" in SolrCore.execute log, even if I set wt=json in
paramters, is this normal?
This is the jQuery call to the server:

$.getJSON('solrServer.html', {query:
escape($('input[name=query]:visible').val())}, function(data){
    var view = '';
    for (var i=0; i<data.response.docs.length; i++) {
        view += '<p>'+data.response.docs[i].contenuto+'</p>';
    }
    $('#placeholder').html(view);
});

Thanks for reading.

The java client (SolrServer) can only operate with xml or javabin
format. If you need to get the json response from Solr by using java
you could just use a http client directly and bypass the solr client.

yes, to control the format used by the client there's a method
HttpSolrServer#setParser that set's the client parser (that also
overrides the wt param when the request is made)
