Re: [OT] ConnectionPool question
Chris, as long as we are having fun its all good. I think this question is something many developers ask. I have seen it here and in other forums. You are correct, everything is wrapped. The connection wrapper spawns statment wrappers which spawn result set wrappers, and everything is tracked in parent child relationships.

I'm not sure how calling Connection.close (where the Connection object is one from DBCP) would possibly be able to close ResultSet and Statement objects created by the underlying connection. Unless, I suppose, they decided to wrap /everything/ and register all the ResultSet and Statement objects handed-out by the underlying Connection for the purposes of (possibly) closing them later. I should really read the source :) Below is the DBCP code that keeps track of open statements/result sets and closes them when the connection is closed (BDCP 1.2.2). Yup: it looks like they do wrap/register everything and then close it for you. It's nice that they followed the spec, here :) - -chris - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

Re: errno 110 in mod_jk
To narrow down I just left one node running and started test. When I look at JkStatus worker I see even though all other nodes are down it's still showing OK in the status.

How to configure App for static files
Is it any way to configure Tomcat to serve static files from particular folder on the disk ? I suspect It should be some kind of simple application, but have no idea how to configure it. Any help/hints are welcome.
RE: How to configure App for static files
From: Maxim Kazitov [mailto:mvka...@gmail.com] Subject: How to configure App for static files Is it any way to configure Tomcat to serve static files from particular folder on the disk ? Assuming you're using a supported version of Tomcat (you didn't tell us), create a file named conf/Catalina/[host]/[appName].xml that contains a Context element with a docBase attribute pointing to the directory of interest. The value of [host] depends on what you have in server.xml; the default is localhost. The value of [appName] is the URI path to use to access the static information. For the current Tomcat version, the doc is here: http://tomcat.apache.org/tomcat-6.0-doc/config/context.html - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

Re: Want to customise the tomcat's session logic
To my knowledge, there is no path attribute in the session. Are you proposing that you add one? deploy one app in tomcat by having context xml in catalinadomainxxx.xml . When you access this app check the session u will find the path attribute with xxx in it. So... do you mean that you want to deploy one web application (into a single context), but you want to separate certain parts of the session into different areas of the webapp? yes I don't believe that deploying the same webapp multiple times into different contexts has any effect on session sharing: Tomcat will treat them as different webapps and no session sharing will occur unless you have taken other steps to share sessions between contexts. Session sharing will not occur for different context. But i need to have single context still session should not be shared. Is it possible in single context.?? Consider i have one login app, after login i track the state by session. First i login that website in single tab in browser and session was created with details in it. And in another tab or window i need to login with different username without sharing the session. But if i did this first created session was overwrite by second session. Wat i need is two different session for same webapp running under single tomcat??? IS it possible??
