Speech Api - Jetty ALPN/NPN has not been properly configured.

[naushad97]

I am getting the below exception when running the sample "speech" application as a plain java application. I have not run it on any server as of now.

Sample application can be found at- https://github.com/GoogleCloudPlatform/java-docs-samples/tree/master/speech/cloud-client.

Exception in thread "main" java.lang.IllegalArgumentException: Jetty ALPN/NPN has not been properly configured.

I have tried most of the steps provided over the net but no luck. It uses google cloud speech version - 0.20.3-alpha. I have also tried with google cloud speech version -0.17.1-alpha but same issue.

Where are you using this? Tomcat perhaps - there is a known bug that should be fixed shortly.

[naushad97]

I have not used in any container or server. I have only runt it as a normal Java Application. Through maven I have run the example application as -
mvn exec:java -Dexec.mainClass=com.example.speech.QuickstartSample
I have also run it from eclipse as - > Run as Java Application. Same issue is occurring.
Issue is consistent across the system on windows 7 and windows 10.

You should try adding io/netty/netty-tcnative-boringssl-static/2.0.3.Final/netty-tcnative-boringssl-static-2.0.3.Final.jar to your classpath.

[naushad97]

@mamtaT I tried by adding netty-tcnative-boringssl-static-2.0.3.Final.jar in classpath but still the same issue.

I also added alpn-boot-7.1.0.v20141016.jar (as I am executing on jdk1.7.0_51, OS- Windows 7) in Bootstrap entries (described here) and run the application from Eclipse IDE- It is throwing the below error #-

Without alpn-boot-7.1.0.v20141016.jar, it is always throwing the error - Jetty ALPN/NPN has not been properly configured.

[lesv]

My guess is that it's attempting to write to some directory (probably 'tmp') and can't do so. You picked the correct version of alpnboot, so that looks good. Though you really shouldn't have needed it as you already have the correct version of BoringSSL twice. (and it does run on Windows).

I suspect upgrading to the .1 of the cloud libraries won't help much, but it would be nice if you'd try.

Have you done a gcloud init and gcloud auth application-default login ?? (I would expect a different error message if you haven't, but I want to check).

Lastly, I wonder if perhaps the path's need to be changed to be Windows paths. I'm beginning to suspect that this hasn't been tested on Windows. @gguuss PTAL
(but again, I'd expect a different error message)

Netty Instructions might be worth looking at. source.

I'm trying to find the code that hooks up BoringSSL on Windows, but haven't yet found it, will update if I find it.

[lesv]

So, my understanding is that netty-tcnative-borringSSL (aka netty-tcnative-windows-x86_64 .dll) getting unpacked to a system temp directory. What it's looking like is that your JVM isn't able to write to it for some reason.

[lesv]

Engineering suggested that you might wish to manually unpack the jar.

See https://github.com/netty/netty/blob/64a3e6c69c1ba49ccd7fe0410e6b2131cda9315c/handler/src/main/java/io/netty/handler/ssl/OpenSsl.java#L419

Just unpack the os/arch-specific library anywhere and rename it to just "netty-tcnative.dll". Then configure LIBPATH.

[naushad97]

@lesv Thanks for your response. I will try and let you know.

[naushad97]

I unpacked windows specific library and renamed to "netty-tcnative.dll". Then I configured LIBPATH in windows environment variables and set the value to "netty-tcnative.dll".

Then I run the application in the following way -

1. With alpn-boot-7.1.0.v20141016.jar in bootstrap entries-
   Then it throws the below error (full stack-trace already provided earlier)-
   io.grpc.Context: Storage override doesn't exist. Using default. java.lang.ClassNotFoundException: io.grpc.override.ContextStorageOverride ........

2. Without alpn-boot-7.1.0.v20141016.jar in bootstrap entries-
   It throws the below error (full stack-trace already provided earlier)-
   Exception in thread "main" java.lang.IllegalArgumentException: Jetty ALPN/NPN has not been properly configured. at io.grpc.netty.GrpcSslContexts.selectApplicationProtocolConfig(GrpcSslContexts.java:174) .................

Is it the correct approach?

P.S.
I have set "GOOGLE_APPLICATION_CREDENTIALS" in environment variable to the path of service
account key(json file).
I am running the application on latest version of google cloud api-

 <dependency>
		<groupId>com.google.cloud</groupId>
		<artifactId>google-cloud</artifactId>
		<version>0.21.0-alpha</version>
	</dependency>

[lesv]

<version>0.21.1-alpha</version> is current, so you might try it.

Doesn't sound like things worked at all, since the second option is what should work.

I'm a fan of setting using gcloud init & gcloud auth application-default login as it makes a few things easier. When you use a service account and GOOGLE_APPLICATION_CREDENTIALS you need to make sure you give the account the right IAM privileges. Note the environment variable takes precedence over the gcloud configurations.

Recommendation - try option 2 using the updated library - they wouldn't have done a .1 release unless there was something wrong with the .0

[naushad97]

I tried with the latest version <version>0.21.1-alpha</version> but the same problem. I also set the gcloud init & gcloud auth application-default login after removing GOOGLE_APPLICATION_CREDENTIALS but still the same problem.

[naushad97]

I tried to check OpenSSL and Alpn availability and always showing unavailable though these are present in classpath -

                System.out.println("Is OpenSSL available? " + OpenSsl.isAvailable());
		System.out.println("Is ALPN available?    " + OpenSsl.isAlpnSupported());

		if (OpenSsl.unavailabilityCause() != null) {
			System.out.println("Unavailability cause:");
			OpenSsl.unavailabilityCause().printStackTrace(System.out); 
			return;
		}

It prints the following -

Is OpenSSL available? false
Is ALPN available?    false
Unavailability cause:
