    Migrating from POJO to EJB3 and strange behaviour

    Miloslav Vlach Novice

      I got this exception:


      java.lang.LinkageError: loader constraint violation: when resolving method org.jboss.seam.Component.getInstance(Ljava/lang/String;Lorg/jboss/seam/ScopeType;)Ljava/lang/Object; the class loader (instance of org/jboss/mx/loading/UnifiedClassLoader3) of the current class, org/jboss/seam/ui/AbstractEntityLoader, and the class loader (instance of org/jboss/mx/loading/UnifiedClassLoader3) for resolved class, org/jboss/seam/Component, have different Class objects for the type org/jboss/seam/ScopeType used in the signature


      I don't know, where is problem. The jboss-seam-2.2.0.GA is installed only once.


      Thanks Mila
