So, I'm stupid: the command to dump everything is "?qry", not "get". Getting an error like this is no fun, though. I think I'll fix that. There is another - legit this time - error that I can see when I call ?qry: Mar 05, 2014 4:39:39 PM org.apache.catalina.mbeans.MBeanDumper dumpBeans SEVERE: Error getting attribute Catalina:type=WebappClassLoader,host=localhost,context=/manager jarPath javax.management.ReflectionException: Cannot find getter method getJarPath at org.apache.tomcat.util.modeler.ManagedBean.getGetter(ManagedBean.java:461) at org.apache.tomcat.util.modeler.BaseModelMBean.getAttribute(BaseModelMBean.java:180) at com.sun.jmx.interceptor.DefaultMBeanServerInterceptor.getAttribute(DefaultMBeanServerInterceptor.java:647) at com.sun.jmx.mbeanserver.JmxMBeanServer.getAttribute(JmxMBeanServer.java:678) I'm not sure why this would be happening... could be mismatch with mbeans-descriptor? I'll investigate this one, too. - -chris -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 Comment: GPGTools - http://gpgtools.org Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iQIcBAEBCAAGBQJTF5nPAAoJEBzwKT+lPKRYsHAP/A4Qz2u88pHhpuaX+MQW0PTs fZ6Dc+S36+fvdp2wIVyZ1y2jMIMGV76QuvFTxq2U9PsmQR6Mb1vnTb5SkrN0+9Zh FvN++VECJjFv3JHxTVHiK8+Z+tVP9v3Cii/1eRr3clx6WNoEWRLq+RIVXd6d7w+g emqk6C2CZUqTyDJxwyHYIMhGrf/pjr2HCXCsfJpiZorfhbAEbUlagGLbjrxBfrPN Wxle8PWfIMB/ViUMXf3lf3pFlcZ1dvYUs3XphBYTGM8f9T92nKkKfha234rudeUl 5+vPZHEOFDWXJbiserdOUHxgvEZN/pJCFjV1cwi7n/h5gpz0wIL8M++u9+wrGGZO 0xC1QxLb5TDXtFIM44/RJ4KRExPgynNH/XAn6ypUW2/1OchuFao6lxIbTmC+qXs2 sDdE8U5P2XaDR0Tma1A9QNI2VCvIvgBD9BfbsDDyJgm9Ip2+k8rJMLQHJdRVxL3X 5Xas+m/I+MpOeeC/RSLDSHRCHV0BDKhKFQT08cSbws+Xt5CoA2EgbUUHDp1Wlix8 JvY+yrWz7LFrswG6HjughhzBn72csAw9Jkc1/8aEn1MIRzyYeAzv3JocKRs4TvB6 CmbXYrL7TULI3E7b8xzn4JFxg+jHEqbWga8bU7yNrKDhAwr3nMrU8w6LJVmcL9cu YCNURJmHa+s7GYJkBG/u =UrHC -----END PGP SIGNATURE----- --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
