java.lang.ClassNotFoundException: io.vertx.mongo-service

[Zsolt Kovács]

Hi,

I am unable to figure out why I get this ClassNotFoundException. I am pretty new to vert-x and mongodb, so probably I am doing something silly. The following gist reproduces the error in my environment when I use the 3.0.0-milestone4 version.

Thanks,

Zsolt

do you have the io.vertx:vertx-service-factory jar on your classpath ?

This way would be safer,
vertx.deployVerticle(new MongoServiceVerticle(), options, res -> {
...
});

Thanks Julien, that was the issue. To be honest, it is not clear from the mongodb documentation (3.0), that this dependency is needed.

BTW. I see one more issue. Even if Vertx.vertx().close() was called the JVM does not exit. Is that normal?

Thanks Tam for the info. That usage is not shown in the mongodb (3.0) documentation. Is that intentional, or just a missing bit?

BTW, if run the test code using the MongoServiceVerticle() I get this exception:

java.lang.IllegalStateException: address field must be specified in config for service verticle

BUT using 'service:io.vertx.mongo-service' throws a different one:

com.mongodb.MongoException: java.io.IOException: Connection  was refused by remote host.

at com.mongodb.connection.InternalStreamConnection.open(InternalStreamConnection.java:110) ~[mongodb-driver-core-3.0.0-beta3.jar:na]

at com.mongodb.connection.DefaultServerMonitor$ServerMonitorRunnable.run(DefaultServerMonitor.java:127) ~[mongodb-driver-core-3.0.0-beta3.j

From my end user point of view, this 2 approaches are identical, so I would expect them to have the same result. Actually I like the default config approach :)

it should indeed be added in the documentation as a “NOTE”, could you create an issue for that in the project please ?

I don’t think it should be , perhaps you can provide a “reproducer” for your case ?

I have updated my original example gist to use deploy MongoServiceVerticle instance without configuration. This throws IllegalStateException which is captured in the handler, but after the close the code does not exit. I am run as java application in eclipse.
