Tim, can I ask you to please try on Tomcat 5.5.20? If nothing else, that would help us prioritize our work, as 5.0.16 is quite an old release and the 5.0 branch isn't receiving much active work these days. Behavior still exists in clustered 5.5.20 -- does not need to be farm deployed, as it turns out. In a cluster, only the / app is revealed, while in a single instance of tomcat, /manager and all other apps appear. Tim 12/27/2006 Updating version to 5.5.20. Thanks Tim.

Patch that fixes this bug
Still affects 5.5.x. Patch attached that fixes this.
This has been fixed in 5.5.x and will be included in 5.5.28 onwards. |
If I deploy a war file manually across multiple clustered servers, and then look at the admin application, I see: + Tomcat Server + Service (Catalina) + Host (localhost) + Context (/mywebapp) + Context (/manager) + Context (/admin) . . . However, if I deploy using the farm deployer, I do not see any applications under the Host node (except for the default / in a brand-new tomcat install. ) This is on RHEL V.4, Tomcat 5.5.12, in a three-way cluster. Same environment (QA) without farm deployment shows the app just fine. It also reproduces on 5.5.17 on RHEL, and on Windows XP. Occasionally, the following exception appears in catalina.out: javax.management.AttributeNotFoundException: Cannot find attribute className at org.apache.commons.modeler.BaseModelMBean.getAttribute(BaseModelMBean.java:306) at com.sun.jmx.mbeanserver.DynamicMetaDataImpl.getAttribute(DynamicMetaDataImpl.java:96) at com.sun.jmx.mbeanserver.MetaDataImpl.getAttribute(MetaDataImpl.java:181) at com.sun.jmx.interceptor.DefaultMBeanServerInterceptor.getAttribute(DefaultMBeanServerInterceptor.java:638) at com.sun.jmx.mbeanserver.JmxMBeanServer.getAttribute(JmxMBeanServer.java:659) at org.apache.webapp.admin.Lists.getValves(Lists.java:401) at org.apache.webapp.admin.Lists.getValves(Lists.java:452) at org.apache.webapp.admin.TomcatTreeBuilder.getValves(TomcatTreeBuilder.java:462) at org.apache.webapp.admin.TomcatTreeBuilder.getContexts(TomcatTreeBuilder.java:310) at org.apache.webapp.admin.TomcatTreeBuilder.getHosts(TomcatTreeBuilder.java:263) at org.apache.webapp.admin.TomcatTreeBuilder.getServices(TomcatTreeBuilder.java:185) at org.apache.webapp.admin.TomcatTreeBuilder.getServers(TomcatTreeBuilder.java:144) at org.apache.webapp.admin.TomcatTreeBuilder.buildTree(TomcatTreeBuilder.java:101) at org.apache.webapp.admin.SetUpTreeAction.execute(SetUpTreeAction.java:125) at org.apache.struts.action.RequestProcessor.processActionPerform(RequestProcessor.java:419) at org.apache.struts.action.RequestProcessor.process(RequestProcessor.java:224) at org.apache.struts.action.ActionServlet.process(ActionServlet.java:1192) at org.apache.struts.action.ActionServlet.doGet(ActionServlet.java:412) at javax.servlet.http.HttpServlet.service(HttpServlet.java:689) at javax.servlet.http.HttpServlet.service(HttpServlet.java:802) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:252) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:173) at org.apache.webapp.admin.filters.SetCharacterEncodingFilter.doFilter(SetCharacterEncodingFilter.java:123) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:202) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:173) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:213) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:178) at org.apache.catalina.authenticator.AuthenticatorBase.invoke(AuthenticatorBase.java:514) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:126) at org.apache.catalina.cluster.tcp.ReplicationValve.invoke(ReplicationValve.java:247) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:105) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:107) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:148) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:868) at org.apache.coyote.http11.Http11BaseProtocol$Http11ConnectionHandler.processConnection(Http11BaseProtocol.java:663) at org.apache.tomcat.util.net.PoolTcpEndpoint.processSocket(PoolTcpEndpoint.java:527) at org.apache.tomcat.util.net.LeaderFollowerWorkerThread.runIt(LeaderFollowerWorkerThread.java:80) at org.apache.tomcat.util.threads.ThreadPool$ControlRunnable.run(ThreadPool.java:684) at java.lang.Thread.run(Thread.java:595) Reference: http://mail-archives.apache.org/mod_mbox/tomcat-users/200604.mbox/%3C00b501c6599b$cc8db600$3a0119ac@tim%3E http://mail-archives.apache.org/mod_mbox/tomcat-users/200605.mbox/%3c00e101c673a3$b0899d30$3c0119ac@timlap%3e
