Hi ! (I've mailes this to the user list before, but didn't get answer, so i try on this list because I think it could by a bur or/and version 4 is more advanced, so better ask the developpers) I've installed tomcat 4-beta to check out the filtering mechanism. But I have some problems to configure the JDBCRealm. When I start up tomcat i got a exception in logs/catalina.out: Starting service Tomcat-Standalone Apache Tomcat/4.0-b1 Catalina.start: LifecycleException: This Realm has already been started LifecycleException: This Realm has already been started at org.apache.catalina.realm.JDBCRealm.start(JDBCRealm.java:542) at org.apache.catalina.core.ContainerBase.start(ContainerBase.java:1142) at org.apache.catalina.core.StandardEngine.start(StandardEngine.java:217) at org.apache.catalina.core.StandardService.start(StandardService.java:353) at org.apache.catalina.core.StandardServer.start(StandardServer.java:454) at org.apache.catalina.startup.Catalina.start(Catalina.java:654) at org.apache.catalina.startup.Catalina.execute(Catalina.java:595) at org.apache.catalina.startup.Catalina.process(Catalina.java:176) at java.lang.reflect.Method.invoke(Native Method) at org.apache.catalina.startup.Bootstrap.main(Bootstrap.java:157) I have the following in my conf/server.xml: <Realm className="org.apache.catalina.realm.JDBCRealm" debug="99" driverName="org.gjt.mm.mysql.Driver" connectionURL="jdbc:mysql://62.208.90.143/urlaubstage?user=urlaubstage;passw ord=something" userTable="user" userNameCol="username" userCredCol="passwd" userRoleTable="user_roles" roleNameCol="rolename" /> Please mail me, if you heard of this problem or know how to solve it.
