Eclipse Scout - HelloScout error [message #1841380]

Hello everyone

It's my first time posting in this forum,.. I checked a few answers already but couldn't find the proper solution to it.

I am stuck with the "hello scout" introduction tutorial. My hello scout doesn't event start properly, after generating it and 'running' it.

Here's the error:

Hi Mike,

welcome to the forum!

Your stacktrace says that the config property with key 'scout.auth.privateKey'does not exist or has an invalid value.

The property is defined in /Users/mike/eclipse-workspace/helloscout/helloscout.ui.html.app.dev/target/classes/config.properties.

Have you changed that value? When creating a new Scout project using the eclipse wizard the property is automatically generated. Maybe create a new project and compare the property with your existing one.
Please note that if you want to use the value from the newly created project, you have to adjust the public key too (scout.auth.publicKey), which is in the config.properties of the server (helloscout1.server.app.dev).

Those values, (scout.auth.privateKey and scout.auth.publicKey) are not updated for me by the installation, I've tested it a couple of times.

values are...

scout.auth.privateKey=TODO_use_org.eclipse.scout.rt.platform.security.SecurityUtility.main(String[])

and /helloscout.server.app.dev/src/main/resources/config.properties

scout.auth.publicKey=TODO_use_org.eclipse.scout.rt.platform.security.SecurityUtility.main(String[])

Edit: so it would seem to be related to this:

Hi Tom

As Claudio said:

Quote:

Your stacktrace says that the config property with key 'scout.auth.privateKey'does not exist or has an invalid value.

Your property exists, but the value there is not valid, because you see the "TODO" which has been automatically generated by the archetype. _You_ have to do something to solve that TODO.
Namely start the SecurityUtility Java program to generate a valid public/private key pair which is unique for you.

For that, simply run the main() of the org.eclipse.scout.rt.platform.security.SecurityUtility class, by command line or in your IDE. It will output the two keys required for the config in the console output.
Something like this:

base64 encoded key pair:
  private key: MD4CAQAwEAYHKoZIzj0CAQYFK4EEAAoEJzAlAgEBBCByRQXu6SweGVzPHqgTaGcUz4B/v/pX8f4KB8kASx7tbQ==
  public key:  MFYwEAYHKoZIzj0CAQYFK4EEAAoDQgAEtRVgRUz3SjO8kGeeH7XLX1/Nt7pebFFLFyK9h2mZFaogWVWw2iLxarCdxEZxQ/4etw6eLlSBoaBEtKVlXr+fjQ==

Check the property reference for more details about the two properties:

Thanks, I got 2 keys generated, and I get further.

Next error is

Caused by: java.security.SignatureException: Curve not supported: secp256k1 (1.3.132.0.10)
	at jdk.crypto.ec/sun.security.ec.ECDSASignature.engineSign(ECDSASignature.java:486)

	at org.eclipse.scout.rt.platform.security.SunSecurityProvider.createSignature(SunSecurityProvider.java:282)
	... 30 common frames omitted

Which is a bit odd, because secp256k1 seems to have been disabled for java 16, so I tried switching to oracle-jdk 11, which doesn't match the generated projects compliance level of 16.

Ah, ok so it seems the example helloscout project works when imported and run as oracle-jdk-11

Hi Tom

Thanks for analyzing that issue. It seems this never showed up here, because we use a version 11 VM.
We had issues in the past with the security providers and different JREs and this seems to be a similar case.

I'll check if we can make this work with newer VMs. At least we can document which VMs are supported for the Hello World.

In the meantime I hope you can continue with the oracle-jdk-11 (or probably any other VM with version 11, or less than 16).

Cheers,
André
