Hi, i try to use your LoginModule but got some trouble with the org.jboss.web.tomcat.security.AdvancedWebCallbackHandler within jboss-service.xml JBoss 4.0.4 start runs into an exception. As per description i put all you *jar's into my server lib directory. I already try to put these into a seperate security-service.xml in my deploy directory but without any success... Any suggestions? 20:06:13,671 INFO [ServiceConfigurator] Problem configuring service jboss.security:service=JaasSecurityManager org.jboss.deployment.DeploymentException: Exception setting attribute javax.management.Attribute@6a435f on mbean jboss.security:service=JaasSecurityManager; - nested throwable: (java.lang.ClassNotFoundException: Unexpected error during load of: org.jboss.web.tomcat.security.AdvancedWebCallbackHandler, msg=org/jboss/web/tomcat/security/WebCallbackHandler) at org.jboss.system.ServiceConfigurator.setAttribute(ServiceConfigurator.java:698) at org.jboss.system.ServiceConfigurator.configure(ServiceConfigurator.java:332) at org.jboss.system.ServiceConfigurator.internalInstall(ServiceConfigurator.java:460) at org.jboss.system.ServiceConfigurator.install(ServiceConfigurator.java:171) at org.jboss.system.ServiceController.install(ServiceController.java:226) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:585) at org.jboss.mx.interceptor.ReflectedDispatcher.invoke(ReflectedDispatcher.java:155) at org.jboss.mx.server.Invocation.dispatch(Invocation.java:94) at org.jboss.mx.server.Invocation.invoke(Invocation.java:86) at org.jboss.mx.server.AbstractMBeanInvoker.invoke(AbstractMBeanInvoker.java:260) at org.jboss.mx.server.MBeanServerImpl.invoke(MBeanServerImpl.java:659) at org.jboss.mx.util.MBeanProxyExt.invoke(MBeanProxyExt.java:190) at $Proxy4.install(Unknown Source) at org.jboss.deployment.SARDeployer.create(SARDeployer.java:249) at org.jboss.deployment.MainDeployer.create(MainDeployer.java:953) at org.jboss.deployment.MainDeployer.deploy(MainDeployer.java:807) at org.jboss.deployment.MainDeployer.deploy(MainDeployer.java:771) at org.jboss.deployment.MainDeployer.deploy(MainDeployer.java:755) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:585) at org.jboss.mx.interceptor.ReflectedDispatcher.invoke(ReflectedDispatcher.java:155) at org.jboss.mx.server.Invocation.dispatch(Invocation.java:94) at org.jboss.mx.interceptor.AbstractInterceptor.invoke(AbstractInterceptor.java:133) at org.jboss.mx.server.Invocation.invoke(Invocation.java:88) at org.jboss.mx.interceptor.ModelMBeanOperationInterceptor.invoke(ModelMBeanOperationInterceptor.java:142) at org.jboss.mx.server.Invocation.invoke(Invocation.java:88) at org.jboss.mx.server.AbstractMBeanInvoker.invoke(AbstractMBeanInvoker.java:260) at org.jboss.mx.server.MBeanServerImpl.invoke(MBeanServerImpl.java:659) at org.jboss.mx.util.MBeanProxyExt.invoke(MBeanProxyExt.java:190) at $Proxy5.deploy(Unknown Source) at org.jboss.system.server.ServerImpl.doStart(ServerImpl.java:477) at org.jboss.system.server.ServerImpl.start(ServerImpl.java:357) at org.jboss.Main.boot(Main.java:200) at org.jboss.Main$1.run(Main.java:464) at java.lang.Thread.run(Thread.java:595) Caused by: java.lang.ClassNotFoundException: Unexpected error during load of: org.jboss.web.tomcat.security.AdvancedWebCallbackHandler, msg=org/jboss/web/tomcat/security/WebCallbackHandler at org.jboss.mx.loading.RepositoryClassLoader.loadClassImpl(RepositoryClassLoader.java:527) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3966505#...
