Re: Getting other Sessions
List servers = MBeanServerFactory.findMBeanServer(null); MBeanServer server = (MBeanServer)servers.get(0); ObjectName objName = new ObjectName(Catalina:type=Manager,path=/contextPath,host=localhost); String sessionIds = (String)server.invoke(objName,listSessionIds,null, null); You can get the rest by each sessionId. Take a look at the MBean docs on how to make jmx calls. There is a jmxproxy in 5.5 manager app which shows all of the mbeans by default, and lets you test your queries. Complex, but not hard. -Michael Greer On Feb 22, 2005, at 11:17 PM, Joseph Shraibman wrote: I want to make an admin page in my application.

Re: can I develop dan deploy myapps as regular user at linux?
Why not chown the whole tomcat directory to yourself (or your group)? Then you can just pop in your apps. Tomcat doesn't need to (and should not) run as root. No need to restart either. -Michael Greer On Feb 22, 2005, at 8:47 AM, Mohd. Jeffry wrote: Hi, I'm pretty new with tomcat, 1 month to be exect.

Re: Tomcat 5.5 working, BUT not outside of webapps/
Maybe take a look at the current $CATALINA_HOME/Catalina/localhost/ context files. Delete the old ones for your webapp and examples, so it will reload from server.xml On Feb 22, 2005, at 11:39 AM, Matt wrote: Well, I've tried all sorts of configurations, so I was hoping to get a clean example from someone who had it working. I changed the stock Tomcat 5.5 server.xml file to add the following (within the pre-existing, as well as the only, HOST tag for localhost, and I have tried with/without a slash for path, and with forward or backward slashes in docbase): CONTEXT path= docbase=C:/Inetpub/wwwroot/MYwebapps debug=0 reloadable=true / ...and I have edited the stock Tomcat 5.5 uriworkermap.properties file to add the directory relative to the additional docbase (I've also tried without the .jsp specificity at the end of the line to handle everything): /MYjsp-examples/*.jsp (the jk_1.2.8.exe installer puts it all in its own folders in $CATALINA_HOME's parent, not within $CATALINA_HOME/bin, and also sets the registry properly - anything else this nice installer does for me? It doesn't appear to set environment variables $CATALINA_HOME or JAVA_HOME - do I need to do this manually? The webapps examples work fine without these variables set though, so is this a deprecated step?) So, if I have copied the webapps folder (and everything in it) to the C:\Inetpub\wwwroot folder and renamed it MYwebapps, and renamed jsp-examples therein to be MYjsp-examples (and fixed the .html to point to the right path), I would have thought that I could run examples from the new directory as well. I don't see any path info. (non-relative) elsewhere that would cause problems and need to be changed? However, if uriworkermap.properties is edited properly, I get a Tomcat 404 error starting with the docbase, when clicking any example (.jsp link; the .html ones still work fine, since they're not handed-off to Tomcat) from the main page: http://localhost/MYwebapps/MYjsp-examples/index.html ...the same files still work fine if I go back to the original location: http://localhost/jsp-examples I've even tried making new HOST tags as well, but Tomcat won't start if you try to define two HOST tags for the same system whether I use a machine name, IP or whatever.

I would manually declare that class to be implementing the Servlet interface. Can't hurt (can it?) if it already does so by its ancestry. At least it is quick to add and test.

volunteering to enhance docs for mod_jk local_worker_only (server quiescence)
I have been looking around the web to figure out how to implement server quiescence (starving sessions from server in balanced set to take it down for maintenance). The documentation on the jakarta site confused me, and it looks like I am not alone. More people have questions than answers. I think the trouble it that the docs start with the properties, and then describe their complex interactions and possible outcomes. It might be helpful to write a HOWTO starting from the use case instead: HOWTO Quiesce Load-balanced Tomcat Server. Should I take the trouble? Does this belong instead on the Apache wiki? I will need some help to get it right, so I wrote here to see if I could post drafts and get corrections from the community. thanks, -Michael Greer - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
