Here is the problem: I have installed newest jboss (with tomcat) and cocoon2 I have bould and instaled both without problems, except i got some exception with the tomcat test war. I can deploy cocoon.war without problems. when i access it with http://localhost:8080/cocoon i get the following cocoon 2 internal server error: java.lang.NullPointerException at org.jboss.tomcat.security.JBossSecurityMgrRealm.authenticate(JBossSecurityMgrRealm.java:113) at org.apache.tomcat.core.ContextManager.doAuthenticate(ContextManager.java:837) at org.apache.tomcat.core.RequestImpl.getRemoteUser(RequestImpl.java:341) at org.apache.tomcat.facade.HttpServletRequestFacade.getRemoteUser(HttpServletRequestFacade.java:251) at org.apache.cocoon.environment.http.HttpRequest.getRemoteUser(HttpRequest.java:128) at org.apache.cocoon.Cocoon.debug(Cocoon.java:367) at org.apache.cocoon.Cocoon.process(Cocoon.java:415) at org.apache.cocoon.servlet.CocoonServlet.service(CocoonServlet.java:538) at javax.servlet.http.HttpServlet.service(HttpServlet.java:853) at org.apache.tomcat.core.ServletWrapper.doService(ServletWrapper.java:405) at org.apache.tomcat.core.Handler.service(Handler.java:287) at org.apache.tomcat.core.ServletWrapper.service(ServletWrapper.java:372) at org.apache.tomcat.core.ContextManager.internalService(ContextManager.java:797) at org.apache.tomcat.core.ContextManager.service(ContextManager.java:743) at org.apache.tomcat.service.http.HttpConnectionHandler.processConnection(HttpConnectionHandler.java:213) at org.apache.tomcat.service.TcpWorkerThread.runIt(PoolTcpEndpoint.java:416) at org.apache.tomcat.util.ThreadPool$ControlRunnable.run(ThreadPool.java:501) at java.lang.Thread.run(Thread.java:484) I hope someone can help my.
