LedgerSpecificDecimalMonetaryAmountFormat is an implementation of a formatter (as defined in that spec) that has dynamic formatting rules based on the scale and precision of a ledger

Ok! thanks!

@lelorrieta java-ilp-core is using gradle for building . Either you directly use the gradle plugin in eclipse to update the dependencies automatically or, from the command line, follow next steps:
1 - navigate to the java-ilpc-core directory
2 - execute
gradle install
gradle eclipse
(will update .project file)
3 - In eclipse, press F5 (refresh) on the java-ilp-core project. Eclipse will re-read the .project file and update dependencies.

Note: In the dependencies section of the java-ilp-core/build.gradle you will also find the "coordinates" used by gradle to identify the javax money library in the gradle jar repository. Gradle will download the corresponding jar to a route similar to ${HOME}/.gradle/cache/.../money-api.1.0.1.jar when executing "gradle install". You can then add it manually to your project in eclipse (not recomended, just as a last option if nothing else work).

In Eclipse, maybe you need first to right-click on the java-ilp-core project, choose "Configure" -> Add gradle nature to make eclipse "aware of gradle " for this particular project.

All, here's a link to the ILP Java call agenda -- feel free to suggest any additions, either here or during the call. https://docs.google.com/document/d/1AenpP_qw9UXlMMHvUh462n_BqdtrghQKexnyIYUFn_8/edit#heading=h.e7t58zfj9kvz

Hi All, just in case you didn't see this in the github chatter, I've added a wiki explanation of how to use the new Codec framework for java-ilp-core. This allows for the reading/writing of Java ILP objects to/from ASN.1 OER (and in the future, JSON, Protobuf, or whatever encoding you prefer). https://github.com/interledger/java-ilp-core/wiki/InterledgerPacket-Handling-Framework

@sappenin - FYI, I've started updating java-ilp-client based on the changes in java-ilp-core. It will need the ILQP codecs though, so I've started adding them to java-ilp-core.

@andrew-g-za

@sappenin - i've pushed my changes so far to https://github.com/interledger/java-ilp-core/tree/ilqp-oer. I landed up having to add Oer32Uint and Oer128Uint and change Oer64Uint, thats where i've stopped for now.

David Fuelling

@sappenin

@andrew-g-za Looks good to me - want to create a PR?

Andrew Gates

@andrew-g-za

not yet, i'd like to complete the ILQP codec first, then have one PR for all of it. Hoping to get to that this friday.

Michiel de Jong

@michielbdejong

@sappenin So did you manage to deploy a server that implements the WebFinger + PluginVirtual endpoints? Can we test it with connectorland?

Juan Carlos Gallardo

@jgallare

@michielbdejong now that you mentioned connectorland, has something happened to it? It's not loading the lists for me or Enrique :S

Michiel de Jong

@michielbdejong

@jgallare yes sorry, back up now. it recently seems to manage to corrupt its stats.json file, and then refuses to load

David Fuelling

@sappenin

@michielbdejong I have a deploy in google for the Java virtual plugin, but it's unable to connect to connector.land. Either the credentials you forwarded are incorrect, or I'm assembling them incorrectly. Unfortunately, I won't have time to work on it till this weekend, however. If you can see anything in your server logs for the creds you supplied, let me know.

Michiel de Jong

@michielbdejong

I need to configure your server's URL on the connectorland side

the peering has to be mutual, otherwise it doesn't work

Enrique Arizón Benito

@earizon

@all Is anybody connected to the meeting. The link https://bluejeans.com/910408466/ shows an error

David Fuelling

@sappenin

Coming on now

I think this is the right link: https://bluejeans.com/795795755

I think I messed up the calendar invite / I accidentally set the date for next week, Adrian may not join

Andrew Gates

@andrew-g-za

Hey @sappenin - i got the same issue with the invite. And it looks like i got the timezone wrong so i'm an hour late, my bad :(

Outlook doesnt seem to like the invite.ics file either, has anyone else had that issue?

Enrique Arizón Benito

@earizon

@andrew-g-za same problem with outlook. I just set-up the meeting manually in the calendar.

Andrew Gates

@andrew-g-za

will do, thanks @earizon. Hopefully i wont get the timezone wrong next time :D

David Fuelling

@sappenin

@adrianhopebailie looks like you fell off the call - we'll wait a few for you to come back on...

@jgallare and @andrew-g-za - not sure if the time zones got mixed up again for the java call, but we're on now if you want to join.

Andrew Gates

@andrew-g-za

@sappenin thanks, just joined.

David Fuelling

@sappenin

@andrew-g-za When you get a sec, I think you can merge interledger/java-ilp-core#52

Andrew Gates

@andrew-g-za

@sappenin thanks. will you click the approve button for the PR - you and adrian were requested as reviewers.

@adrianhopebailie - if you get a chance could you please take a look at interledger/rfcs#230, or see if you can raise its visibility? It may be semi-trivial, but i think it has a big impact on correctness.

David Fuelling

@sappenin

@andrew-g-za my bad - approved!!

Enrique Arizón Benito

@earizon

@all Hi, I will not be able to assist to today's java call. Anyway I can summarize my work in Interledger has been centered around creating a link map to resync with current work. I think it can be useful to any others, it's available @ https://htmlpreview.github.io/?https://github.com/earizon/IT_notes/blob/master/Interledger/interledger_map.html
Juan Carlos is on vacation, but I ignore if he will connect remotely.
Regards!
Enrique

@andrew-g-za

@sappenin is the meeting id 795795755 or 958996426?

David Fuelling

@sappenin

It's the 6246 one - I'm running a bit behind and will be on in about 3-4 mins if that works

Andrew Gates

@andrew-g-za

no worries, looks like its you and me. take your time, we'll sync up when you are ready

David Fuelling
