1. Does your web application start, at all? Does you filter start? 2. How exactly are you registering your MBean? Are you using Modeler API for that? (Registry.registerComponent(....)) 3. Maybe run with a debugger? > <?xml version="1.0"?> > > <mbeans-descriptors> > <mbean name="RequestStats" > className="org.apache.catalina.mbeans.ClassNameMBean" > description="Server statistics and configuration" > domain="Catalina" > type="mbeans.RequestStats"> 4. I see that many <mbean>s have a "group" attribute. Yours does not have one. (Actually it seems that this attribute is optional and is ignored. There are no calls to ManagedBean.getGroup() except in ManagedBean.toString()). 5. I hope that you do not have the second copy of your jar inside of your webapp. So that it shadows the one in the lib/ directory. 6. Apparently many mbean descriptors are pre-loaded when Tomcat starts - in o.a.c.mbeans.MBeanUtils.createRegistry() Best regards, Konstantin Kolinko --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
