Solr Solaruim Client->ping is failing

Question

I am new to this stuff. I just inherited this olde system! I managed to get Solr running, and am trying to execute some old code that rebuilds the Solr data. The client ping is failing and I don't understand why.

Here is the code that is trying to initiate a re-index

// these are correct, now Solarium is falling over
// with a 404.  pile of junk

print(SOLR_SERVER_HOSTNAME . "\n");
print(SOLR_SERVER_PORT . "\n");
print(SOLR_SERVER_CORE . "\n");

            $options = array(
                'adapteroptions' => array(
                    'host' => SOLR_SERVER_HOSTNAME,
                    'port' => SOLR_SERVER_PORT,
                    'core' => SOLR_SERVER_CORE,
                    'timeout' => 60
                )
            );
        }

        try {
            // Ping the Solr server to check its availability


        // create a new client.  This seems to work
            $this->client = new Solarium_Client($options);
        if ($this->client) {
        print("Solarium returned something \n");
        print_r($this->client);
        print("\n");
            } else {
        echo 'Solarium screwed the pooch';
            }


        // and create a ping whatever that means
        // this also seems to work

            $ping = $this->client->createPing();
        if ($ping) {
        print("ping creation worked \n");
        print_r($ping);
        } else {
        print("ping creation failed \n");
        }

        // this always fails and terminate the
            // program run

            $this->client->ping($ping);

        } catch (Solarium_Exception $e) {
        print("exeption from ping request \n");
            throw $e;
        }

    print("about to reset \n");

        // Reset all filters and queries and process request params if requested
        $this->reset($request);
    }

The Solr admin screen is up. I have an empty collection1..

Here is the output from the trace I stuck in here

Any hints? It's the first time I have seen this stuff.

Cheers, Mark.

Fixed. The core name was getting flattened in another bit of code. Two constants for the same property. Two different values! – Addinall 22 secs
