Hello everyone, I have the impression that resource injection (using @Resource annotation) is not executed when using shared library (in common/lib folder). I have created a HttpSessionListener , with a datasource declared like this: | @Resource(mappedName = "java:DefaultDS") | private DataSource ds; | ... | This listener is bundled in a jar file, which I have put under <JBOSS_HOME>/common/lib to make it available for all applications running on my Jboss application server. Then I have a web application which uses this HttpSessionListener by declaring it in it's web.xml. What I see is that when web application is deployed and listener is executed the datasource (ds) is always = null.This means the container did not execute the dependency injection of the datasource. Note that when I add the jar file (with listener) to WEB-INF/lib of my web application, it DOES get executed. So it seems that JBoss does not do dependency injection when @Resource annotations are put on classes which are in the common/lib folder. Could someone please help because I don't want to deploy my shared jar with each application individually. Many thanks in advance.
