--------------------------------------------------------------
We are trying to migrate from WebLogic to JBoss but having some issues (mostly class loader issues).

we have an ear file with 7 web appliations, no EJB and everything else controlled by spring (msg, JPA, etc)

I can not get the ear to deploy, so I thought I would first try some WebApps individually.

I installed snowdrop as per the instructions.

Now, when I try and depoy the WebApp I get numerous errors.

1 - JBOSS is scanning the files for EJB's and I get numerous errors like 

12:45:48,158 WARN  [org.jboss.as.ee.component.deployers.ResourceInjectionAnnotationParsingProcessor] (MSC service thread 1-3) Can't handle @Resource for ENC name: externalAccountManager on class com.crowncastle.service.IsiteUserServiceImpl since it's missing a "lookup" (or "mappedName") value and isn't of any known type12:45:48,158 WARN  [org.jboss.as.ee.component.deployers.ResourceInjectionAnnotationParsingProcessor] (MSC service thread 1-3) Can't handle @Resource for ENC name: externalAccountManager on class com.xxxxxxx.service.IsiteUserServiceImpl since it's missing a "lookup" (or "mappedName") value and isn't of any known type

These should be handled by spring, not JBOSS  

2nd. 

I get class not found on classes  that are in the (inside of jars)


War
     WEB-INF
          lib directory.  


Caused by: java.lang.ClassNotFoundException: net.sf.ehcache.CacheManager from [Module "*org.springframework.spring:snowdrop*" from local module loader @4cee32 (roots: C:\development\jboss-as-7.0.2\jboss-as-7.0.2.Final\modules)]

    ... 18 more


I am unclear where the jar files should be placed if not in the WEB-INF/lib directory.

thx
