Hi all,
There are problems with the configuration of DeltaSpike on weblogic 12c.
When a web application is deployed that contains deltaspike as jars, the
configuration is not performed properly.
- *ServiceLoader.load(ConfigSourceProvider.class); *
=> doesn't find the service configuration file in the jar
- *ClassLoader cl = ClassUtils.getClassLoader(this); // The context class
loader
Enumeration<URL> propertyFileUrls = cl.getResources(PROPERTY_FILE_NAME);*
=> doesn't find the apache-deltaspike.properties file
A possible solution is to unjar the deltaspike jar files into the classes
directory as described here for CODI (1)
Debugging the system today revealed that during the execution of the CDI
extensions (that is where we touch the configuration for the first time)
the context classloader
(*Thread.currentThread().getContextClassLoader();*) isn't the web-app
class loader but his parent (which exists for the
application as a whole)
But ClassUtils.class.getClassLoader(); (or any other class from deltaspike)
points at that time to the web-app classloader which can see for instance
the apache-deltaspike.properties file.
On GlassFish 3 and JBoss AS 7, the Context class loader
and ClassUtils.class.getClassLoader() points to the same when the
Extensions are processed.
*So my proposition is the following:*
a) Change in org.apache.deltaspike.core.api.config.ConfigResolver
*ServiceLoader.load(ConfigSourceProvider.class,
ConfigResolver.class.getClassLoader());* instead of *
ServiceLoader.load(ConfigSourceProvider.class);*
Then serviceLoader will use the web-app classloader on all 3 app servers.
b) Change how resources are found; here we have several options
1) Change org.apache.deltaspike.core.util.ClassUtils#getClassLoader that it
returns o.getClass().getClassLoader(); when parameter o is not null.
2) Create a specific method that returns resources, something like
*public List<URL> findResources(Object o, String fileName)*
*{*
* ClassLoader cl = o.getClass().getClassLoader();*
* try*
* {*
* Enumeration<URL> propertyFileUrls = cl.getResources(fileName);*
* .....*
*}*
3) Create a specific method that returns resources that first tries the
context class loader, and if that doesn't find anything, tries the
classLoader of the object passed as parameter.
If we can agree, I create a JIRA ticket for it.

Rudy
