HTTP POST - Mongo Connection Issue - mongodb

Question

I am attempting to perform an HTTP POST to a local mongo database based off a simple example (http://www.tothenew.com/blog/using-groovys-http-builder-library/) and am having trouble keeping the connection open long enough to make any posts. Here is my code:
public static void postToDatabase(String item, final log) {
try {
String baseURL = "http://localhost:27017"
URIBuilder uri = new URIBuilder(baseURL)
HTTPBuilder http = new HTTPBuilder(uri)
String path = "Test/testCollection"
http.post(path: path, body: item, requestContentType: URLENC) { resp ->
log.info("POST Success: ${resp.StatusLine}")
assert resp.StatusLine.statusCode == 201
}
} catch(HttpResponseException ex) {
ex.printStackTrace()
} catch(ConnectException ex) {
ex.printStackTrace()
}
}
Once the program reaches the http.post call, here is the following stack trace I receive:

For whatever reason, it seems like the program likes to close the connection before it even makes the post. Any suggestions?

I think you are using the wrong port number for mongodb use 28017 according to http://docs.mongodb.org/ecosystem/tools/http-interfaces/
