I want to create a private blockchain network using EthereumJ and connect it to a project implementing EthereumJ. I tried modifying ethereumj.conf file but thats not working. How to do it?

how did you modify the config file?– q9fCommented Aug 8, 2016 at 10:09

I made the peer list empty changed network id to 2 and changed genesis to sample-genesis.json– Abhishek RanjanCommented Aug 8, 2016 at 11:45

I don't think you can connect to private network, EthereumJ itself acts as a node. (Please correct me if I am wrong).– Vijay GadhamCommented Aug 23, 2016 at 16:03

Here is some sample code to connect ethereumj to a testnet from github - ethereumj-core/.../samples/TestNetSample.java:
private final String config =
// network has no discovery, peers are connected directly
"peer.discovery.enabled = false \n" +
// set port to 0 to disable accident inbound connections
"peer.listen.port = 0 \n" +
"peer.networkId = 161 \n" +
// a number of public peers for this network (not all of then may be functioning)
"peer.active = [" +
" { url = 'enode://9bcff30ea776ebd28a9424d0ac7aa500d372f918445788f45a807d83186bd52c4c0afaf504d77e2077e5a99f1f264f75f8738646c1ac3673ccc652b65565c3bb@peer-1.ether.camp:30303' }," +

"] \n" +
"sync.enabled = true \n" +
// special genesis for this test network
"genesis = frontier-test.json \n" +
"database.dir = testnetSampleDb \n" +
"cache.flush.memory = 0";
Search this site for the parameters to set up a private network and adjust the config parameters in the example above.
