Re: Solrj Exception
Hi,
we have found that some of the jars (like stax-api-xxx.jar, stax-utils.jar,
stax-xxx-dev.jar, commons-codec-xxx.jar) were missing in our application's
lib directory, by adding these libraries the mentioned exception resolved.

Re: Sending http post to solr indexing
I just updated my code. There no error , and getting back 200, but when I
perform a search in solr/admin, I get no results.
Here's my code:
@Override
public void index(ProductData product) {
HttpClient httpclient = new DefaultHttpClient();
HttpPost post = new HttpPost(url);
post.setHeader("Content-type", "application/json");
HttpParams params = new BasicHttpParams();
params.setParameter("commit", "true");
post.setParams(params);
String d = "[{ \"id\" : \"1234\", \"name\" : \"My Product\" } ]";
try {
StringEntity entity = new StringEntity(d);
entity.setContentEncoding("UTF-8");
post.setEntity(entity);
HttpResponse response = httpclient.execute(post);
System.out.println(response);
System.out.print(post.getParams().getParameter("commit"));
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
} catch (ParseException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
And this is output:
HTTP/1.1 200 OK [Server: Apache-Coyote/1.1, Content-Type:
application/xml;charset=UTF-8, Transfer-Encoding: chunked, Date: Mon, 21
May 2012 02:43:57 GMT]
true
On the server side, it's showing:
May 21, 2012 2:43:57 AM org.apache.solr.core.SolrCore execute
INFO: [] webapp=/solr path=/update/json params={} status=0 QTime=0
I am not sure if this is because I am using HttpComponents the wrong way,
or I am doing something wrong with JSON string, or missing a parameter. As
far as I know, I need to add (commit=true) to the request param. But it
doesn't look like this is being received on the server.
Thank you.
