    Mavenized Seam project: Could not create Component: securityRules (NoClassDefFoundError: org.drools.RuleBase)

    Marcel Stör Newbie

      Disclaimer: I'm quite familiar with Maven but not with Seam.


      I'm in the process of moving a friend's Seam project from Ant to Maven. After a few failed attempts I mainly followed these instructions: http://kasper.eobjects.dk/2009/04/seam-ejbs-and-ear-packaging-in-maven.html. Hence, I'm building an EAR.


      Upon deployment (JBoss online admin console) I get:


      java.lang.RuntimeException: Could not create Component: securityRules
              at org.jboss.seam.init.Initialization.addComponent(Initialization.java:1202)
              at org.jboss.seam.init.Initialization.installComponents(Initialization.java:1118)
              at org.jboss.seam.init.Initialization.init(Initialization.java:733)
              at org.jboss.seam.servlet.SeamListener.contextInitialized(SeamListener.java:36)
              ...
      Caused by: java.lang.NoClassDefFoundError: org/drools/RuleBase

              at java.lang.Class.getMethods(Class.java:1410)
              at org.jboss.seam.Component.hasAnnotation(Component.java:1158)
      



      This is irritating because all three Drools JARs (api, compiler, core) are in the root of the EAR. I also tried placing them in /APP-INF/lib but the results were the same. I even tried having them in the WAR's /WEB-INF/lib...same result.


      Worse, I don't know if this is a JBoss issue, a Seam issue or a Drools issue.


      For the record, here's the content of the EAR...

      I'd be very happy to get a few hints from the Seam community.
