I'm trying to create a simple sample that shows JBoss Modules and source code is checked in at: https://github.com/arun-gupta/wildfly-samples/tree/master/jboss-modules Also created the following directories in "modules": modules/org modules/org/samples modules/org/samples/greet modules/org/samples/greet/greet-api-1.0-SNAPSHOT.jar modules/org/samples/greet/greet-simple-1.0-SNAPSHOT.jar modules/org/samples/greet/modules.xml modules.xml looks like: <?xml version="1.0" encoding="UTF-8"?> <module xmlns="urn:jboss:module:1.0" name="org.samples.greet"> <resources> <resource-root path="greet-api-1.0.0-SNAPSHOT.jar" /> <resource-root path="greet-simple-1.0.0-SNAPSHOT.jar" /> </resources> </module> The web application accesses a service from API module but no results are returned. No error logs, no service not resolved error, nothing. Seems like I'm doing something incorrectly basic. Suggestions how to debug this further ? Thanks, Arun

Seems like the sample has more issues as just adding "main" directory did not enable resolution of service. How would we typically debug this scenario ? What kind of loggers to be turned on ?

Here is how I enabled it: /subsystem=logging/logger=org.jboss.modules:add /subsystem=logging/logger=org.jboss.modules:write-attribute(name="level", value="TRACE")

We found inital issue, it was typo in modules.xml instead of module.xml But there are different issues :) On Tue, Feb 18, 2014 at 10:38 PM, David M.

Hey Arun, Are you trynig to do this using standalone JBoss Modules? If so... why not look at the work we've done with Furnace - https://github.com/forge/furnace It's basically CDI-light, and is what we use to power the Forge Addon service mechanism. I'd be happy to share more details if this is something you're interested in. If you're trying to use Wilfly's native module system and service container for this, then I can't be of much help :) But thought I'd ask. ~Lincoln On Tue, Feb 18, 2014 at 8:36 PM, Arun Gupta <arun.gupta(a)gmail.com&gt; wrote: > > Adding beans.xml in the implementation module solved the issue. > > I updated the implementation module and copied the JAR file over to > org/samples/greet/main directory but had to restart the application > server in order to pick up the new implementation. > > Are the modules not dynamically loaded ?
