Any takers (or takes) on this one. I posted it a few days ago. The problem does not seem to be with the authentication, but with the refereneces to the Logger class. Peter I have been trying to set up a JBDCRealm using postgresql 7.0.2 under redhat linux with tomcat 3.3-M2. I got the authentication to work, but ran into the following problem when trying to access the Context List. Error: 500 Location: /admin/contextAdmin/contextList.jsp Internal Servlet Error: java.lang.NoClassDefFoundError: org/apache/tomcat/util/log/Logger at contextAdmin.contextList_1._jspService(contextList_1.java:67) at org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:119) at javax.servlet.http.HttpServlet.service(HttpServlet.java) at org.apache.tomcat.facade.ServletHandler.doService(ServletHandler.java:500) at org.apache.tomcat.core.Handler.service(Handler.java:223) at org.apache.tomcat.facade.ServletHandler.service(ServletHandler.java:448) at org.apache.tomcat.core.ContextManager.internalService(ContextManager.java:788) at org.apache.tomcat.core.ContextManager.service(ContextManager.java:701) at org.apache.tomcat.modules.server.Ajp13Interceptor.processConnection(Ajp13Interceptor.java:162) at org.apache.tomcat.util.net.TcpWorkerThread.runIt(PoolTcpEndpoint.java:424) at org.apache.tomcat.util.threads.ThreadPool$ControlRunnable.run(ThreadPool.java:497) at java.lang.Thread.run(Thread.java:498) Looking in container/tomcat_util.jar, I see org/apache/tomcat/util/qlog/Logger.class, but no log/Logger.class. Is this the problem? If so, how do I fix it (being new to java)? Peter -- Peter B. West [EMAIL PROTECTED] http://powerup.com.au/~pbwest "Lord, to whom shall we go?"
