[Java] Problem with deployVerticle

[Valentin Davy]

Hello everybody,

I want to use the method deployVerticle of the class Vertx.

Thus, I saw the example there: https://github.com/vert-x3/vertx-examples/tree/master/core-examples/src/main/java/io/vertx/example/core/verticle/deploy
But even with this example, when I use vertx run DeployVerticle, I always receive the following error message:

java.lang.ClassNotFoundException: io.vertx.example.core.verticle.deploy.OtherVerticle

I didn't change anything in the two files DeployVerticle.java and OtherVerticle.java except the package line.

Can you see the problem?

Thank you for your help.

What version of Vert.x are you using?

[Tim Fox]

Try running it from the IDE

If you want it to run from the command line, you should do it from target/classes:

vertx run io.vertx.example.core.verticle.deploy.DeployExample 

or set the class path to includes target/classes:

vertx run deploy_example.js -cp ../../../../../../../../../target/classes/

Thank you for your answers:

- I'm using Vert.x3 Christian
- I prefer to use the command line because it's easier for me Tim :D
- Clement, I don't see what you call /target/classes.
I saw the reference in a pom.xml but that's all :/

That's fine, but clearly, the example is referencing a Java class so you'll need to compile that first if you insist on running that example from the command line.

If you run it from the IDE, the IDE will automatically compile it for you, so it's simpler.

- Clement, I don't see what you call /target/classes.

Ah ok, I understand why I should use an IDE but I don't see the reference to a Java class.

The reference is here:

https://github.com/vert-x3/vertx-examples/blob/master/core-examples/src/main/java/io/vertx/example/core/verticle/deploy/DeployExample.java#L26

[Valentin Davy]

But, "io.vertx.example.core.verticle.deploy.OtherVerticle" is a java class no?

Or maybe, the method deployVerticle takes class files as parameters?

Yes, that's a fully qualified class name.

When you run the example it can't find the class because you haven't compiled it.

Or maybe, the method deployVerticle takes class files as parameters?

[Valentin Davy]

Ok thank you for your help, I'm going to see the different solution I have =)

[Valentin Davy]

It works, thanks a lot!
I used my IDE and I succeeded in using deployVerticle.

[Darshan]

hi sir,
i m also facing this problem, i compiled it using my IDE, but still failed to deploy the verticle.

i have attched some snapshots so that u can know my problem.

Please Find Attached,

with regards,

com.whiteklay.second.app is just a package name. The verticle class name seems to be com.whiteklay.second.app.secondapp
