ERROR DATOMIC CLOUD S3 AWS

Sun, 11 Dec 2022 17:43:52 +0000

I'm trying to connect with the datomic cloud, but when I connect with the client I get the following error:
Execution error (NoClassDefFoundError) at com.amazonaws.services.s3.AmazonS3ClientBuilder/standard (AmazonS3ClientBuilder.java:46).
Could not initialize class com.amazonaws.services.s3.S3CredentialsProviderChain

Will REBL be open-sourced?

On the assumption that it doesn't play any tricks that are not available to other Datomic users, what are the reasons for keeping it as a private repo?

Datomic cannot connect: java.lang.NoClassDefFoundError

Wed, 17 Feb 2021 16:01:19 +0000

I was following the Datomic tutorial, got everything set up on AWS and a succesful response from the curl {:s3-auth-path [bucket-name]}

After that I think that a client was created successfully:

(ns try-datomic.db
  (:require [datomic.client.api :as d]))

(def cfg {:server-type :cloud
          :region "eu-central-1"
          :system "db-learn"
          :creds-profile "default"
          :endpoint "http://entry.db-learn.eu-central-1.datomic.net:8182/"
          :proxy-port 8182})

(def client (d/client cfg))

Response from declaring a client is:

2021-02-17 17:48:24.708:INFO::nRepl-session-6***6: Logging initialized @13975ms to org.eclipse.jetty.util.log.StdErrLog

After that when trying to create a database with:

(d/create-database client {:db-name "movies"})

I get this error:

Execution error (ExceptionInfo) at datomic.client.api.async/ares (async.clj:58). java.lang.NoClassDefFoundError: javax/xml/bind/DatatypeConverter

Please help.

How to store secrets in datomic cloud

Fri, 06 Sep 2019 09:07:44 +0000

Locally I'm using https://github.com/juxt/aero to read in a local secrets.edn file that is not tracked by version control intentionally so that secrets.edn doesn't reach github since that's a public repo

but the flip side of that means secrets.edn would not be in my git repo for sending up to Datomic cloud, I suppose I can make my GitHub repo private but if possible I'd prefer an alternative

Is there anyone doing websockets with datomic ion on aws

Thu, 01 Aug 2019 18:54:02 +0000

We are trying to setup our clojure server to handle websockets but we are using datomic's ion infrastructure on aws, making it not so easy. I wonder if anyone has tried it or has any pointers?
