mbeans-descriptors.xml
Hi, I have a customised implementation of JDBCRealm. I am encoutering the following exception at start up. ServerLifecycleListener: createMBeans: MBeanException java.lang.Exception: ManagedBean is not found with TomcatJDBCRealm at org.apache.catalina.mbeans.MBeanUtils.createMBean(MBeanUtils.java:615 ) at org.apache.catalina.mbeans.ServerLifecycleListener.createMBeans(Serve rLifecycleListener.java:574) at org.apache.catalina.mbeans.ServerLifecycleListener.createMBeans(Serve rLifecycleListener.java:783) at org.apache.catalina.mbeans.ServerLifecycleListener.createMBeans(Serve rLifecycleListener.java:751) at org.apache.catalina.mbeans.ServerLifecycleListener.createMBeans(Serve rLifecycleListener.java:339) at org.apache.catalina.mbeans.ServerLifecycleListener.lifecycleEvent(Ser verLifecycleListener.java:206) at org.apache.catalina.util.LifecycleSupport.fireLifecycleEvent(Lifecycl eSupport.java:166) at org.apache.catalina.core.StandardServer.start(StandardServer.java:218 2) at org.apache.catalina.startup.Catalina.start(Catalina.java:510) at org.apache.catalina.startup.Catalina.execute(Catalina.java:400) at org.apache.catalina.startup.Catalina.process(Catalina.java:180) at java.lang.reflect.Method.invoke(Native Method) at org.apache.catalina.startup.Bootstrap.main(Bootstrap.java:203) I googled and found that i need to have any entry in mbeans-descriptors.xml. I added the required mbean to this file, jarred it with other classes and placed it under server/lib. I stil encounter the above exception. Any clues whats happening, or if I am missing anything.

Re: How to turn on secure (MD5 Digest) version of WebDAV?
What Security Realm are you using? JDBC,JNDI, MemoryRealm? I have had problems with DIGEST authentication for JDBC and JNDIRealm. I had to implement getPassword() and getPrincipal() methods to make it work with digest authentication. -- Uddhav - Original Message - From: "Basil Bourque" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Monday, March 17, 2003 7:54 AM Subject: How to turn on secure (MD5 Digest) version of WebDAV? > How does one turn on the secure logon feature (MD5 Digest) in Tomcat's > WebDAV server? > > I cannot find any documentation on the "auth-method" parameter in the > virtual host's "web.xml" file: > > > BASIC > Tomcat Supported Realm > > > I tried replacing "BASIC" with "DIGEST".

Re: Increase heap for a specific webapplication
Hi, My interpretation of the problem is that it may not be related to heap. >From the statistics, the memory heap consumption seems to be within bearable limits. I suspect that the the first servlet after being heavily loaded is starving susbsquent requests for want of some resources critical to its processing. Are you using any resource pools in the servlet that are synchronized? This seems to be the most likely reason since your cpu utilisation is also very low, which points that you may have some I/O wait cycles blocking other requests (or some other synchronous blocking activity). -- Uddhav - Original Message - From: "Raja Sekhar" <[EMAIL PROTECTED]> To: "Tomcat Users List" <[EMAIL PROTECTED]> Sent: Friday, March 14, 2003 11:41 AM Subject: RE: Increase heap for a specific webapplication > Hi Shapira, > > I have actually increased the heap size on my server. Its a 4 CPU processor with 4 GB Ram. So I increased my VM options when starting the tomcat to start with 128M and go upto 1.24GB. I suppose thats pretty huge for that. The problem here is, it doesn't max out the memory. When the tomcat stops responding, I check for the heap size and the CPU processes. Both are normal. For example, these are the statistics what I have when my CPU is actually hanging. Just have a look at them > > The total memory occupied by the tomcat was 145 M of which > 121M was resident.
