Not a able to Write my first vertical

[jyothesh k]

HI,

I am jyothesh K and i am new to vertx. I saw the documentation given and was able to setup the vertx on my windows 7 system. Now i am trying to write a verticle present in the http://vertx.io/core_manual_java.html#writing-verticles unser writing verticle heading. And i am getting the following errors:

the error log is here:


E:\vertx_sample\server.java:9: error: cannot find symbol
    vertx.createNetServer().connectHandler(new Handler<NetSocket>() {
    ^

Have you looked at the examples?

http://vertx.io/examples.html

Also.. you didn't show us your code, so it's hard to tell what is going wrong.

[jyothesh k]

Thank you for your reply,I have written this snippet in a note and tried to execute it.

import org.vertx.java.core.Handler;
import org.vertx.java.core.net.NetSocket;
import org.vertx.java.core.streams.Pump;
import org.vertx.java.platform.Verticle;

public class server extends Verticle {

  public void start() {
    vertx.createNetServer().connectHandler(new Handler<NetSocket>() {
      public void handle(final NetSocket socket) {
        Pump.createPump(socket, socket).start();
      }
    }).listen(1234);
  }
}

Do i need to include any other things in to the program...

How exactly you start it ?

As, I already said, I placed the vertx installation directory into my E drive. Then had written the code in one note file in a file called samplevertx which is different from the installation directory. I also set the environment path so that i can execute it from command prompt in any location. Later i tried to execute that code file, then the following errors came up. I didnt include any package to that source code. I was trying that in eclipse. there also it is showing error that org.vertx is not available.

What exact command are you calling to start it, at the command line?

[Tim Yates]

Also,

public class server

should be

public class Server

[Norman Maurer]

Good catch !

By far the easiest way to get started with Vertx is using a script. You literally only need to write a single file, and no build, and you can start playing around. If you want a library, you can add it to the classpath. This isn't appropriate for a real project, but it's appropriate for first steps and playing around, which is what you're doing.

[jyothesh k]

vertx run server.java

[Jez P]

Hmm that looks consistent with the examples here https://github.com/vert-x/vertx-examples/blob/master/src/raw/java/README.md, although it would appear that your classpath is missing something (not sure why that would be)

One other question (which someone is bound to ask so it may as well be me): Which version of vert.x are you using? I don't know if this has changed between 1.3 and 2.0.

I would second what the others are saying about using scripts rather than Java. I'd also suggest using the maven or gradle templates, which make life a lot easier (in my experience anyway). However, someone on this group must have done what you're trying to do so hopefully one of them will spot the problem for you.

Cheers

I'd suggest running the examples in the vertx-examples repository as a
starting point.
