Hi All,

I'm using the JOTA : Library 0.9.11-SNAPSHOT API.

I have the example found at https://github.com/iotaledger/iota.lib.java/blob/master/jota/src/test/java/jota/SendMessageTest.java working from an Eclipse JUnit run. I know PoW is a fundamental requirement for the Tangle, but how is this done when running an example like this? How to verify that PoW is being done?

I have been using server http://node03.iotatoken.nl:15265 for testing - I've sent 4000+ tryte zero balance message transactions, and have verified the transactions days later. All is working. PoW must have been done - right? 

Besides wanting to fully understand how JOTA and the Tangle actually works, I've now run into a situation where that node03 server no longer is working for me. So, I switched over to server http://radiantqs.de:14265. First I verified a transaction I sent from node03 (using address FOJHXRVJRFMJTFDUWJYYZXCZIJXKQALLXMLKHZFDMHWTIBBXUKSNSUYJLKYRQBNXKRSUXZHDTPWXYD9YF) a couple days ago was still in the Tangle, and radiantqs came back very quick with the transaction. But now, when trying to use radiantqs to sendTransfer (using address LBKRT9VNDECLHZJHPUAUKIPBWFYYHLOOCRXYURDJEYCQTGTGBHPFA9XMNTNWKCMHLSJUMCOFNOGNDBXGZJHMEFYUTX) I don't get a response back - still waiting after 45 minutes. 

BTW - It's not just the node03 and radiantqs servers that aren't working for me - I've tried 20 servers found at https://iotanode.host/ and can't get any to work.
I feel like I'm missing some important knowledge about servers and using the Tangle. Like, don't send 4000+ tryte zero balance messages. Or, pay some MIOTA to a server so that they'll keep doing your transactions. 

I appreciate any help on this you can provide.

Thanks,
Bob

Hey Bob, thanks for the question. You might also try asking about this on one of the technical channels on the Discord. When you get an answer, it would be really helpful if you could post the answer in this thread so that others can learn as well.

Hi Winston - Instead of a Discord server posting, I will post to https://iota.stackexchange.com/questions and report back here any info I learn.

Thanks,

Bob
