I am using an @Resource annotation in a class instantiated in a ServletContextListener's contextInitialized(...)
method, but the member is always null. Here's my sample code.
Listener:
public void contextInitialized(ServletContextEvent sce) {
System.err.println("In contextInitialised");
new ResourceListenerTargetTest().executeMe();
}
ResourceListenerTargetTest:
@Resource(name="MyJDBCResource")
private DataSource source;
public void executeMe() {
/*try {
InitialContext ictx = new InitialContext();
source = (DataSource)ictx.lookup("java:comp/env/MyJDBCResource");
} catch (NamingException e) {
e.printStackTrace();
}*/
System.err.println("source is " + source);
}
If I switch the comments and run the manual resource lookup, it works fine.
Should the @Resource annotation work like this, when used in a contextInitalized method?
Appserver is WAS 7.0.0.5, if it should work then I guess it's a bug? Can anyone confirm?
