How can I run a Java app, created with the Java bindings, against a ledger deployed on Daml Hub?

Questions Features & Bugs
1

The Java bindings docs say (Java bindings — Daml SDK 1.18.1 documentation):

The Java bindings library lets you connect to a Daml Ledger via a secure connection. The builders created by DamlLedgerClient.newBuilder default to a plaintext connection, but you can invoke withSslContext to pass an SslContext . Using the default plaintext connection is useful only when connecting to a locally running Sandbox for development purposes.

Secure connections to a Daml Ledger must be configured to use client authentication certificates, which can be provided by a Ledger Operator.

How can I obtain the certificate for that? I haven’t found any info about that in the Daml Hub docs.

The certificate used on hub.daml.com and *.daml.app are provided by Let’s Encrypt, and its root certs are commonly pre-installed on system trust stores. As such, you don’t actually need to specify any cert at all, although you still need to specify that you want to use TLS.

In the Java quickstart, change these lines:

DamlLedgerClient client =
    DamlLedgerClient.newBuilder(ledgerhost, ledgerport)
        .build();

to

DamlLedgerClient client =
    DamlLedgerClient.newBuilder(ledgerhost, ledgerport)
        // use the roots of trust already present on the system,
        // ledgers running on *.daml.app domains use certs
        // provided by Let's Encrypt
        .withSslContext(GrpcSslContexts.forClient().build())
        // on Daml Hub, you will still need an access token;
        // it can be supplied here or per operation
        .withAccessToken(accessToken)
        .build();

General notes on TLS and gRPC

  • A few of the daml commands are built on top of the Haskell/C++ bindings, which unfortunately do not utilize the system trust store. In this case, you are required to re-supply the publicly available root CA cert for these gRPC clients that do not utilize the trust store, even though Daml Hub’s cert is otherwise available. The documentation for that is here: https://hub.daml.com/docs/api/#section/Authentication-and-Client-Configuration. A link to the current CA cert is there, and can be supplied to clients that require it.

  • If you are using JVM gRPC libraries, there is much better cross-platform support for using the system trust store. If Daml Hub changes certificate providers or Let’s Encrypt makes material changes to the way that they generate certificates (note that this has happened recently), you will need to re-download the CA cert and redeploy wherever you used this cert. For this reason, we do not recommend supplying this cert explicitly when using Daml Hub unless you are forced to by a client library.

  • Daml Hub does not use mutual TLS, so regardless if your client supports the system trust store or not, you do not supply a key file.

I have implemented the above and am getting “io.grpc.StatusRuntimeException: INTERNAL: Received unexpected EOS on empty DATA frame from server”.

Steps taken:

  1. Tried a couple different party access tokens - assume it wouldn’t matter for just creating the client but never know.
  2. Called the API via postman using the access token to make sure the ledger could be hit and hit using the access token.
  3. Added logging to see exactly where it was throwing it. It is on "client.connect();

private static DamlLedgerClient getDamlLedgerClient() throws SSLException{
System.out.println(“Before creating client”);
DamlLedgerClient client = DamlLedgerClient.newBuilder(hostIp, hostPort)
.withSslContext(GrpcSslContexts.forClient().build())
.withAccessToken(accessToken)
.build();
System.out.println(“After Creating Client, before connecting”);
client.connect();
System.out.println(“After connecting”);
return client;
}

Now I have this error with the IOU Quickstart tutorial:

Have you supplied an access token? PERMISSION_DENIED suggests that you’re able to make a connection properly, but the request is getting rejected because the token is either missing or invalid.

Yes, I have, like this:

image1204×398 64 KB

And now I have a different error:

<html><head>
<meta http-equiv="content-type" content="text/html;charset=utf-8">
<title>502 Server Error</title>
</head>
<body text=#000000 bgcolor=#ffffff>
<h1>Error: Server Error</h1>
<h2>The server encountered a temporary error and could not complete your request.<p>Please try again in 30 seconds.</h2>
<h2></h2>
</body></html>
10

Is there a chance the Party literal you are sending is incorrect? Please see this post for details: JAVA gRPC request error to DAML Hub

I’m not sure about the 502; If you are consistently getting these please let us know and we’ll look more closely into it. Thanks!

As @RyanMedlen and @cocreature could make it work, it must work, I’m looking at it more closely to see what I am doing wrong.
