Description Oliver Kišš 2011-10-18 12:50:41 UTC 
Description of problem:

Spring context:component-scan does not detect classes with Spring 2.5 and EAP6

When "<context:component-scan base-package="org.package"/>" is added to Spring XML, none of components (annotated with @Component, @Controller, etc) located in base-package are autodetected.

Classes have to be defined manually in the xml
(for example
<bean id="clinicController" class="org.springframework.samples.petclinic.web.ClinicController"/>)
because autodetection does not work.
Comment 1 Marius Bogoevici 2011-10-18 13:02:22 UTC 
Running Spring 2.5 on EAP5 or later requires the use of Snowdrop.

Comment 3 Oliver Kišš 2011-10-19 08:22:53 UTC 
I didn't provide enough information, I'm sorry. Snowdrop is being used.

I added attachment with WAR of the application.

WAR with corrections

Corrections made as follows:

- fixed web.xml to enable Snowdrop correctly
- replaced Snowdrop 2.0.0.CR1 with 2.0.3.Final (as used by WFK2)
Comment 10 Marius Bogoevici 2012-03-12 03:32:14 UTC 
I don't think we need a technical note for this as the issue is obsolete.

The reason why the submitted example failed was that Snowdrop was enabled incorrectly (verified and attached working example with Snowdrop enabled correctly).

It can be verified by navigating to http://localhost:8080/petclinic-fixed/addPet.do (controller is enabled_

Please note that http://localhost:8080/petclinic-fixed/welcome.do does not work in this version because ClinicController is annotated with @Component instead of @Controller
