About CA-client in HLF Sample

[Luna0214]

if you see the image below,

There is a line "HFCAClient caClient = HFCAClient.createNewInstance("https://localhost:7054", props);"

So far, I cannot find why sample register to single URL with the props. Because
"HFCAClient.createNewInstance("https://localhost:7054", props);"

As I know, there are 2 ORGs in the network.

I just don't know why the CAClient connect to only to ORG1. What about ORG2??

Please help.
