I try to use another OSGi framework for glassfish - eclipse Equinox. But i get similar error:

Error occurred during deployment: Exception while loading the app : java.lang.IllegalStateException: ContainerBase.addChild: start: org.apache.catalina.LifecycleException: java.lang.LinkageError: loader constraint violation: when resolving method "javassist.util.proxy.FactoryHelper.toClass(Ljavassist/bytecode/ClassFile;Ljava/lang/ClassLoader;Ljava/security/ProtectionDomain;)Ljava/lang/Class;" the class loader (instance of org/glassfish/javaee/full/deployment/EarClassLoader) of the current class, org/jboss/seam/util/ProxyFactory, and the class loader (instance of org/eclipse/osgi/internal/baseadaptor/DefaultClassLoader) for resolved class, javassist/util/proxy/FactoryHelper, have different Class objects for the type lassFile;Ljava/lang/ClassLoader;Ljava/security/ProtectionDomain;)Ljava/lang/Class; used in the signature.

I found a solution:

1) Stop glassfish

2) Go to [glassfish3-folder]/glassfish/modules/weld-osgi-bundle.jar and REMOVE from this archive folder "javassist"

3) Copy javassist.jar from Seam 2.3 libs to [glassfish3-folder]/glassfish/lib/

4) Start glassfish

5) Deploy Seam 2.3 example and enjoy
