LoadBalancer2.Factory ClassNotFoundException #7

jgarcia241 · 2017-06-14T15:41:54Z

Hi,

I'm using version 3.4.1 and it is failing to make calls, because it cannot find the class LoadBalancer2.Factory, when creating a VertxChannelBuilder

Looking to latest code, looks that in master branch we no longer have the method loadBalancerFactory with that signature( that accepts that LoadBalancer2.Factory)

Is this a bug ? or am I missing any library in my project?

Kind regards

The text was updated successfully, but these errors were encountered:

vietj · 2017-06-14T18:11:04Z

we have upgraded the master version to the latest gRPC version.

VertxChannelBuilder extends ManagedChannelBuilder which only defines:

public abstract T loadBalancerFactory(io.grpc.LoadBalancer.Factory var1);

So we provide nothing more and nothing less than what the original API provides.

jgarcia241 · 2017-06-14T20:16:29Z

Yep. I saw that on master it was correct.

I'm now including a gradle dependency like:
compile "io.vertx:vertx-grpc:3.4.1"

Is it released or should I manually build and include the jar?

vietj · 2017-06-14T21:33:48Z

the current 3.4.2 release is staging here : https://oss.sonatype.org/content/repositories/iovertx-3685/ you can follow on vertx-dev the release if you like

jgarcia241 · 2017-06-15T13:24:39Z

Almost there!

If I include the vertx-grpc from that maven repo, my add does not startup anymore, as it complains about Netty and Dropmetrics when creating my redis client.- I guess some interface have changed.

If I manually include the vertx-grpc-3-42-jar file in my app , I get the following error on the server:

Upgrading all the app to use 3.4.2 from that staging repo, also makes the startup to fail.

Any clue?

jgarcia241 · 2017-06-15T14:19:52Z

BTW, I tried with gRPC 1.1.2 and 1.3.0 and I get the same error (different lines in jetty files, but kind of the same error)

Thanks

jgarcia241 · 2017-06-16T10:58:16Z

So, after tons of testings, I think I found the issue.

If I deploy the verticle that contains the server as a normal verticle, using (vertx.deployVerticle(new Server()) it works fine.

However, if I deploy the verticle as a service vertx.deployVerticle("service:my-descriptor.json") (with the service json descriptor) , then it fails with the error above, when I call it.

Should we pass this to the vertx-service subproject?

vietj · 2017-06-16T11:09:41Z

could you write a reproducer and link it to this issue for now ?

jgarcia241 · 2017-06-16T12:14:12Z

gprc-service.zip

Find attached an example with 2 launcher, as service and not as service.
Hope this helps

vietj · 2018-01-12T15:01:02Z

can you try with the latest 3.5.1 SNAPSHOT ?

jgarcia241 · 2018-03-07T10:20:41Z

Looks it still does not work if deployed as a service.
This is the stack trace I get:

Works fine if deployed the 'normal' way.
