I'm trying to move a java application from an old server to a new server. The application runs on Tomcat, uses Microsoft SQL Server as the backend DB, and used a system DSN defined in Data Sources (ODBC) to decide where to connect to. The old server used Windows 2000/SQL server 2000, the new server uses Windows 2003/SQL Server 2005. T...
I'm running Tomcat 6.0.18 on Linux. I have a JSP that uses a bean like this: <jsp:useBean id="helper" type="com.example.SomeType" scope="request"/> The page references an attribute of helper with the expression language like this: <!-- This works properly, but could fail silently if the bean name is incorre...
I have a web application and use tomcat-5.5.27, eclipse 3.4 on open SUSE. I use it from eclipse (deploy, run, debug, etc...) I have to set some JNDI resources (datasources) that Tomcat will expose them. These resources are defined now in \META-INF\context.xml. This works fine. But, when I move this file (context.xml) in tomcat-5.5.27/c...
Hi all, does anybody have some ideas on how to achieve that? Or even a good documentation on how to do that? Basicly everything is done in a test standalone version (by a java client or jconsole I am able to call mbeans methods and everything works fine), but I need to put it in my Tomcat servlet.... Thanks for every suggestions! Ro...

Hi, I have installed Apache Tomcat and then I installed NetBeans. Then I added the Tomcat instance to NetBeans servers. Whe I try to run the server from NetBeans, something goes wrong..

I'm currently fixing a JSP project and it currently has a seemingly random collection of .class files in it's Tomcat's WEB-INF folder. As a way of simplifying this, I was planning to get .java files from these classes straight from SVN to WEB-INF folder on server and I got that to work but what would be the simplest way of compiling thes...
Hi I am running a multi level maven project. It has webapps packaged as WAR, which depend on components packaged as JAR files Most of the code changes that i do belong to those JAR files. To test the changes, i need to repackage the JAR and the WAR and deploy externally in tomcat. I tried using sysdeo-tomcat-maven-eclipse plugin, bu...
Whenever I save a JSP file in my WTP project, Eclipse restarts its Tomcat instance. This is sorta driving me nuts. I don't want to disable auto reload completely, I just don't want it to happen when I save a file that doesn't require a restart. I'm not sure how Eclipse WTP works in this regard. Could it be my project structure? The ...
I'm developing a java servlet web application that manages information from multiple databases (all structurally the same) each corresponding to a different "business". The user selects "the current business" which is stored in the session and the application can display or modify that "current business". I would like to use tomcat ...
I've got a fairly normal setup in which Apache proxies requests to a servlet running inside Tomcat over the AJP protocol. We've run this setup on Apache 2.0.46/Tomcat 5.0.28 for ages without problems but have recently updated to Apache 2.2.3/Tomcat 5.5. The problem is that we've noticed that intermittently (maybe one time in 3) Apache...
Okay, I think I already know, but I want to make sure, and this surprisingly simple question was surprisingly hard to google. :P In the tomcat manager, I have some session stats, like so: Active sessions: 1 Session count: 1 Max active sessions: 1 Rejected session creations: 0 Expired sessions: 0 Longest session alive time: 0 s Average ...
We have some independent servers, connected behind a hardware balancer. Each one of the machines is running Apache 2.2, Tomcat 5.0 and mod_proxy_ajp as the connector. Everything works fine, but when Tomcat is shutdown, Apache returns error code 503 (as it's expected to do, I guess). The problem is our load balancer, which doesn't interp...
I'm trying to access a config file from a a servlet inside of .war-file. The problem is, that the default file path is the tomcat root itself and hardcoding the path to the file seems not like an option either. Is it possible to get any information through the ServletContext or any Tomcat variables? ...
Hi all, I am using form based authentication with tomcat. In a certain point in my site I allow the user to decide whether they want to add a role to their account. i.e. a user can decide to be an administrator as well. This request results in a new database entry. Now, in the site I show or hide certain links depending to what roles t...
I am looking for a way to achieve PreparedStatement caching, so as to save recreating the PreparedStatement objects for queries that were already executed in the past. Is there some built in way to achieve this using Tomcat? Or must I program this cache myself? ...

Hello, I am looking for a way to cache prepared statements in a servlet environment (specifically, Tomcat 5.5). This is meant to reduce the number of times that prepared statements are created, i.e. the number of times that connection.prepareStatement(sql) is called. My initial idea was to store PreparedStatement objects in the session...

Basically I'm looking for a way to make the client-side changes (.jsf, .html, .css, .js) to happen a lot faster, and with out having to restart tomcat. And if possible, also a way to make tomcat (or any other Windows + Eclipse compatible Servlet Contain...
