Having trouble accessing the node from front-end/browser

I'm getting this error:
CONNECTION ERROR: Couldn't connect to node http://localhost:8545, is it running?
I'm currently trying to use a Meteor app with a node on a private test network. I've also tried running it on a real node on the real network as well. I am able to access the web3.eth objects, but I can't seem to connect to my node! It's so frustrating!

My app runs on http://localhost:3000

I've tried the following in launching my nodes, neither of them work (they launch okay, but I cannot connect to them through my browser):
geth --networkid 8545 --genesis ~/genesis_block.json --datadir ~/.ethereum_experiment console
geth --rpccorsdomain "*" --rpc --networkid 8545 --minerthreads "1" --datadir ~/.ethereum_experiment --mine

This is what I use to set the provider in the browser console:
web3.setProvider(new web3.providers.HttpProvider("http://localhost:8545"));
