Deploy web applications to JBoss from Eclipse, with dependencies - eclipse

Question

I have a project developed under Eclipse with JBoss tools installed. When I deploy the application to the Jboss server, some helper jar files which are made available to the project through Maven are not copied inside the WEB-INF/lib folder. Hence, I get a ClassNotFound exception at runtime.
Is there any approach to convince Eclipse (or Maven) to copy the jars into the lib folder at deployment?
EDIT: the pom.xml looks like:
<project xmlns="http://maven.apache.org/POM/4.0.0"

The artifact myAuxiliaryStuff should be deployed under WEB-INF/lib, under the jboss deployment server.
Using:
Eclipse: Juno Service Release 1
Jboss: 7.1.1. final
m2e 1.3.1.20130219-1424
eclipse web tools platform 3.4.2.v2013

Answer 1

Eclipse and the plugins are a bit finicky. This is what I've done to get it to work.
Project -> Properties -> Deployment Assembly
Add...
Java Build Path Entries (Next >)
Maven Dependencies (Finish)
The Deploy Properties panel should now include an entry for Source: Maven Dependecies -> Deploy Path: WEB_INF/lib

Answer 2

This is suspicious:
java.lang.NoSuchFieldError: FLOW
Which is related to JSF, if I'm not mistaken. I've got a few suggestions but I'm not an expert in any aspect.
First try to add provided dependency scope for jsf-api and jsf-impl like this (since the JBoss has them):
<dependency>
<groupId>com.sun.faces</groupId>
<artifactId>jsf-api</artifactId>
<version>2.2.0-m09</version>
<scope>provided</scope> // <----- do it for both
</dependency>
AFAIK, JBoss 7.1.1 already has the JSF 2.1.7. So, if you really need the JSF 2.2 you should update the JSF module in JBoss. Here is how to Migration to JSF 2.2.
Another option is to bundle the JSF in to your WAR and inform JBoss to exclude the container version (the one that is shipped with JBoss) of it:
in web.xml add:
<context-param>
<param-name>org.jboss.jbossfaces.WAR_BUNDLES_JSF_IMPL</param-name>
<param-value>true</param-value>
</context-param>
and in jboss-deployment-structure.xml exclude the JBoss's implementation:
<jboss-deployment-structure>
<deployment>
<exclusions>
<module name="javax.faces.api" />
</exclusions>
.
.
.

Answer 3

Based on your description, you only have Eclipse and JBoss Tools in use and dependencies stored in Maven pom files. For Eclipse to become aware of those dependencies, you need to have eclipse-maven integration. M2e is the common choice for it.
So you would need these installed:
m2e
m2e-wtp

Answer 4

Go to the directory where your pom.xml resides and execute following command.
mvn package
This command should create a war file for you to deploy to your application server. This file is a zip file, look to its contents and see if your myAuxiliaryStuff.jar is in web-inf/lib. If it is, your problem lies with eclipse integration with maven.

Answer 5

You seem to have everything installed.
I had this problem too.
Just needed to right click on the project and choose.
"Mark as Deployable"
