Session clustering and session stickiness - Performance issues (was Re: When is Tomcat 5 Release version scheduled to come out?)

Hello Remy, I did not pretend to be whining. Sorry if it souded like that. And thank you very much for your response: I find it really useful. First, thank you for confirming my worries about JMeter not being the best available load testing tool. ** [OT] Do you know of a better (free if

how to customize HTTPSession

Hi, I am new to the java webapp development. I want to store some user data for my app in a client side cookie rather than as a server side object and referencing it with a sessionId. One of the main reasons for that is - we will be running multiple servers load balancing. Since the

Re: how to customize HTTPSession

You might look into implementing the javax.servlet.hhtp.HttpSessionBindingListener interface, this will allow you to act when an object is added/removed from the session. Simply put, you could write valueBound/UnBound methods that set Cookies into the HttpResponse. -Mark [EMAIL PROTECTED]

Re: how to customize HTTPSession

Thanks Mark - the problem with using HTTPSessionBindingListener is that the unbound event is not triggered unless someone calls the session.removeAttribute() or session.setAttribute(name, null). So there is no way for me to set the cookie from the unbound() event without explicitly calling one

HTTP 404 response for directory listing

Hi, I've been tackling this problem since September, I'm hoping someone can shed some light here. I want a directory listing of my files e.g; http://www.somesite.com/directory/ --outputs a dir listing. I am using mod_jk2 with Apache 2.0.4x. If I comment out the LoadModule mod_jk2 I can get a

With the functionality you desire, stay away from the Session classes as defined in the servlet API. Any developer will be greatly confused if they try to read your code created by your description below since you are mixing well known terminology and assumptions. Instead, look into Filters

Apache Tomcat connector FAQ admin?

Hi, I have to move my tutorial listed on the Apache Tomcat Connector FAQ page. I'm wondering who I should contact. I couldn't find the contact info on the FAQ. I guess it's not Frequent enough:) I believe I remember Tim Funk starting it, but maybe it's changed now. I don't have a new URL yet,

Re: Starting Tomcat as nobody...

Tim, % sudo -u nobody /path/to/startup.sh This seems to work. Pros, Cons? I don't have a ton of experience with sudo, but it seems like a good idea -- you can lock down the operations that a user is capable of doing, etc. I have production machines that startup tomcat on boot, and I have

Roeland, does one exist and where can I get a example? The version for 3.x has huge differences and my Tomcat 4.1.29 does not have one (contrary to all the dox). I'm also following the IIS HOW-TO and finding huge descrepencies. The workers.properties file has more to do with the connector that

Re: how to customize HTTPSession

That's the weird part. My workers2.properties uri directive is just for .jsps. It is as follows: [uri:www.mysite.com/*.jsp] group=ajp13:/usr/local/apache2/logs/jk2.socket So I'm not sure why directory requests get forwarded to Tomcat. Christopher Schultz wrote: Atreya, I want a directory

Re: Severity less - DBCP not closing connection.

Thanks a lot for the info. I need more explanation. I thought that Tomcat creates a new thread to serve the new request and continues execution of the current servlet thread after a forward() or redirect(). Now you mean that only after the forward() method is completed the control returns
