Hi guys!

At first thanks to snowdrop team for this useful deployer!

I have two modules within ear: MyProject.jar and MyProject.war.
MyProject.jar contains some spring services, hibernate domains and dao modules.
MyProject.war contains some REST resources and MVC spring components to have web access to
services which are placed in MyProject.jar.

I don't use any EJB beans and to deploy MyProject.jar I use JbossSpring deployer 3.3
(as I use Spring 3.0.x)

So when I run jboss I see in the log that MyProject.jar is loaded twice: one time once
JbossSpring deployer is deploying MyProject.jar and second time once MyProject.war is
deployed by WarDeployer (I'm not sure who deploys war).

Looks like this happens because WarDeployer loads war not in the same scope that
JbossSpring deployer loads jar

Can you please point me on to mistakes in my jboss&spring configuration?

Here is configuration for each module:
...
 MyProject.ear
                     +MyProject.jar
                      |                   +META-INF
                      |                                 +com //compiled classes are there
                      |                                 +core-spring.xml
                      |                                 +core-app-context.xml //part of
spring's services config and annotation scanning
                      |                                 +core-db-context.xml //part of
spring's db config
                      |
                     +MyProject.war
                                         +META-INF
                                         +WEB-INF
                                                        +classes //compiled classes are
there
                                                        +web.xml
                                                        +web-app-context.xml //some
security configuration and all mvc-related stuff

core-spring.xml:

...
 <beans>
    <bean id="core.spring.context"
class="org.springframework.context.support.ClassPathXmlApplicationContext">
     <constructor-arg>
       <list>
         <value>classpath*:/META-INF/*-app-config.xml</value>
       </list>
     </constructor-arg>
    </bean>
 </beans> 
web.xml (here is only neccessary part of file):
...
