(Eclipse 3.4, Ganymede) I have an existing Dynamic Web Application project in Eclipse. When I created the project, I specified 'Default configuration for Apache Tomcat v6' under the 'Configuration' drop down. It's a month or 2 down the line, and I would now like to change the configuration to Tomcat 'v5.5'. (This will be the version of...
Hello, my employer just asked me to run a timed batch process in a J2EE websphere application they have running. It's supposed to run a certain class at 1130 pm everyday. I'm not very familiar with J2EE nor websphere server (or tomcat, in the develpment environment), and I've been digging around but all I've found is about the java time...
In a server-side application running on Tomcat, I am generating full HTML pages (with header) based on random user-requested sites pulled down from the Internet. The client-side application uses asynchronous callbacks for requesting processing of a particular web page. Since processing can take a while, I want to inform the user about pr...
Tomcat (version 5 here) stores session information in memory. When clustering this information is periodically broadcast to other servers in the cluster to keep things in sync. You can use a database store to make sessions persistant but this information is only written periodically as well and is only really used for failure-recovery ra...
By default tomcat will create a session cookie for the current domain. If you are on www.example.com, your cookie will be created for www.example.com (will only work on www.example.com). Whereas for example.com it will be created for .example.com (desired behaviour, will work on any subdomain of example.com as well as example.com itself...
How do i measure how long a client has to wait for a request. On the server side it is easy, through a filter for example. But if we want to take into accout the total time including latency and data transfer, it gets diffcult. is it possible to access the underlying socket to see when the request is finished? or is it neccessary to d...
My Tomcat instance is listening to multiple IP adress, but I want to control what source IP address is used when opening a URLConnection. How can I specify this? ...
I'm trying to create a self signed certificate for use with Apache Tomcat 6. Every certificate I can make always results in the browser connecting with AES-128. The customer would like me to demonstrate that I can create a connection at AES-256. I've tried java's keytool and openssl. I've tried with a variety of parameters, but can't...
I have this workspace downloaded off the web and I try running it on a tomcat server from a fresh installation of Eclipse Ganymede. This particular project came with its own workspace. When I select Tomcat v6.0 I get a message Cannot create a server using the selected type Older tomcat versions are available, though. I guess I...
I'm working on a webapp, and every so often we run into situations where pages will load without applying CSS. This problem has shown up in IE6, IE7, Safari 3, and FF3. A page refresh will always fix the problem. There are 3 CSS files loaded, all within the same style block using @import: <STYLE type="text/css"> @import url([base cs...
I create a web application (war) and deploy it on Tomcat. In the webapp there is a page with a form where an administrator can enter some configuration data. I don't want to store this data in an DBMS, but just in an xml file on the file system. Where to put it? I would like to put the file somewhere in the directory tree where the appl...
The server.xml which controls the startup of Apache Tomcat's servlet container contains a debug attribute for nearly every major component. The debug attribute is more or less verbose depending upon the number you give it, zero being least and 99 being most verbose. How does the debug level affect Tomcat's speed when servicing large nu...

When I start Tomcat (6.0.18) from Eclipse (3.4), I receive this message (first in the log): WARNING: [SetPropertiesRule]{Server/Service/Engine/Host/Context} Setting property 'source' to 'org.eclipse.jst.jee.server: (project name)' did not find a matching property. Seems this message does not have any severe impact, however,...
Our project uses Cruise Control to both build and hot deploy a web application to a remote server (via FTP) running Tomcat in the form of a .war file. Unfortunately, "hot" deploys don't appear to work properly, causing us to reboot Tomcat in response to each deployment. We would really like to do this auto-magically, much like the buil...
This exception peppers our production catalina logs on a simple 'getParameter()' call. WARNING: Parameters: Character decoding failed.

We are currently using Apache 2.2.3 and Tomcat 5 (Embedded in JBoss 4.2.2) using mod_proxy_jk as the connector. Can someone shed some light on the the correct way to calculate / configure the values below (as well as anything else that may be relevant). Both Apache and Tomcat are running on separate machines and have copious amounts of...
How would I go about writing some code to allow access to a Java class in my webapp from the command line. E.g. I have a java class with command line interface, that can runs code in the context of the webapp, with access to the DB etc. I want to log on the machine hosting my WARred app in tomcat and be able to interact with it Where ...
I have a CometProcessor implementation that is effectively doing a Multicast to a potentially large number of clients. When an event occurs that needs propagated to to all the clients, the CometProcessor will need to loop through the list of clients writing out the response. If writing responses block then there is the possibility that...
