I've successfully set up a Corda Open Source 4.3 Testnet node, and I can connect with the Node Explorer. However I'm having difficulty figuring out instructions 3 and 4 found here: https://docs.corda.net/head/testnet-explorer-corda.html
Considering the finance CorDapp has been split into 2 CorDapps, I have copied both of the jar files downloaded in step 3 into /opt/corda/cordapps, before trying step 4 and eventually running the node. Having done that I connected with the Node Explorer and found that I could only select "pay" in the new transaction modal. I have also tried creating 2 matching conf files for each of the CorDapps, with no luck.
