Initializing WeldContainer - HELP PLEASE!

Hi all,

I'm currently working my way through the "Beginning Java EE 7 - Antonio Goncalvez" book (which is good, although some simple things are left to one's own research) and I'm a 'little' stuck where the Main class is written for Weld :

The weld.initialize() method below cannot be found, no idea why :-( Any help would be much appreciated.

Quote:

---

package org.aptovia.javaee7.CDBOOKSTORE;

import org.glassfish.weld.WeldContainer;
import org.jboss.weld.Weld;


/**
* Enterprise Application Client main class.
*
*/
public class Main {

public static void main( String[] args ) {

Weld weld = new Weld();
WeldContainer container = weld.initialize(); //it says here can't find this method! ?! there's an option called 'current()'

System.out.println( "Hello World Enterprise Application Client!" );
}
}

---

No worries, found it: import org.jboss.weld.environment.se.Weld;
NOT: import org.jboss.weld.Weld;

arrrrgg ... so we learn eh.

When in doubt, read the documentation.

Sorry couldn't find that in any documentation :(

Now getting build error with maven:

I have set my pom.xml file to include following dependency (I've put 2.1.0 as version since it seems its the latest version: Maven Repository: org.jboss.weld)
so I'm not sure why getting this error?

Quote:

---

<dependency>
<groupId>org.jboss.weld.se</groupId>
<artifactId>weld-se</artifactId>
<version>2.1.0</version>
</dependency>

Any help much appreciated

OK seems I was missing 'Final' from the end of the version:
The Central Repository Search Engine

Now my proj builds fine, but when trying to execute get following error:

I have in my POM.xml file specified the mainClass: (am I missing something somewhere? the pom.xml file seems Ok according to: Exec Maven Plugin - Usage )

You can't have tried very hard.
JBoss has lots of documentation, including this section covering the SE implementation you are using.

If in doubt, go to the source.

Weld is indeed one of the better documented technologies out there. I must say that JBoss/Red Hat itself has bettered their practices in recent years; it used to be that you had to scour the forums to get answers as a non-commercial user of their stuff, but nowadays everything is neatly documented.

Oh yes.
They seem to have taken a leaf out of the Spring and Hibernate books.

well Hibernate is also JBoss/Red Hat ;) In that respect Hibernate documentation is very lengthy, but it doesn't push the envelope; the HQL documentation for example tends to stick to the basic examples and doesn't show most of the things that you would run into in application that actually do mildly exciting things (such as combining different query structures); I still have to regularly ask Google to find the stackoverflow threads that actually do explain how to do it.

Ah, well, I was thinking JBoss 2003, so pre-Hibernate acquisition.
I still wake up screaming...
