Greetings, I'm looking for a good solution for externalizing the JNDI connection pool information in context.xml of a war so that as the application moves from dev to QA to prod, the war file won't need to be recompiled. Ideally the url, driver, username and password would be variablized and then populated by means of a properties file...

So I'm trying out JSP for the first time. I found a tutorial that details the installation of the tomcat server and the mod_jk Apache module, but it's a bit outdated.

I'm building a relatively simple web-app where the main servlet implements the ServletContextListener interface to determine whether the context has been started or stopped. I've implemented my contextInitialized, contextDestroyed, init and destroy methods (both init and destroy call super on the base class). I've currently implemented n...
I have tomcat 5.5 installed, running and verifiable at http://localhost:8080/. The Tomcat menu option appears in the Eclipse menu bar and I can start and stop Tomcat from there. In Eclipse, it does not show as a Server Runtime Environment in Window - Preferences - Server - Runtime Environments, nor does it appear in the list of environme...
I am editing the jsp files which are residing directly inside tomcat/webapps/myapp/web-inf. But to see the changes i have to restart the server these. As far as i know, jsp changes don't require you to restart the server. The only configuration i found which was related to automatic reloading is reloadable = "true" Set to true if you...
I have an application that is deployed as ROOT.war under /webapps in Tomcat. As it is configured now, I can only access the application via http://www.example.com. I'd like to be able to access it using http://www.example.com/myapp without having to change the fact that it is deployed as ROOT. I have the following in my ROOT.xml: <Co...
How can I evaluate the capacity of Amazon EC2 Amis for my different templates; A) Webserver (Apache/PHP) - pages/sec. B) Database (MySql) - connections/sec. C) App Server (Tomcat) - pages/sec. I was hoping there was some kind of baseline tool that I can use to evaluate the many choices available on EC2 without using my System Under Deve...

I've got an existing WAR file that is not developed by me. I deploy the application to the Tomcat server and after that it is accessible for everybody. Which is not good. I need to restrict the access to the context with HTTP Basic auth. What is the best way to do that? I do not need any sophisticated user management system I just need a...

Basically what I want to do is to be able to send an email to a special email address and the mail should be parsed and then the data is to be processed by my application. Now I can find hundreds of tutorials on how to send mails fro...
We are using the Windows installation of Tomcat 6. By default, the log4j output for our app goes to the ${catalina.base}/logs/stdout_.log file. This log file only rolls over when we restart Tomcat, and the file name always includes the date. I would prefer it to behave like a DailyRollingFileAppender, where it renames the file when it...
I created a web application in Netbeans, and it packages the application in a file called "aa-bb.war". When I run the project in netbeans, I can access it at "localhost:8080/aa/bb". This is all good. Moving the .war file into a standard tomcat installation though, gives me problems. When I drop the .war into the "webapp" directory, it g...
I have a binary value being URL Encoded, and then POSTed to an HttpServlet. The following code shows how I first attempted to extract this data. Very simple except that the result is a String, not bytes. This seemed to work at first, except that an extra byte appeared three bytes from the end. What I eventually figured out was that my d...
