I'm not exactly sure what question to ask here since I don't know the vocabulary... Tomcat servlets (and any server for that matter) work nicely if they are stateless and respond quickly to requests, with state stored in a database. It seems like if I have long-running operations then maybe I want to run some other service in the backgr...

Has anyone tried getting Tomcat to use SSL-J for Tomcat? I'm trying to set up Tomcat to use SSL-J for it's SSL sockets, but I'm having troubles getting things to work and I don't see anything helpful in the SSL-J documentation. Things work fine when Sun's default JSSE provider is used. Any help would be greatly appreciated. Using: Ja...
I have an instance of Tomcat which periodically crashes for unknown reasons. There are no errors left in the logs, only a line in Event Viewer saying "Tomcat terminated unexpectedly". In a test environment I have been unable to replicate the issue. I am therefore mostly restricted to passive monitoring of the production environment. T...
I am doing some experimentation with VPS before moving my application from private Tomcat hosting to cloud. It is a read intensive app built on Struts 2 + Spring + Hibernate + MySql. Its a moderately popular app in India with 1500 visitors and 10,000 pageviews per day. I have some basic questions about choosing a server configuration. 1...
I've written a Servlet that uses the library ganymed-ssh2-build210.jar (it uses these classes: import ch.ethz.ssh2.Connection; import ch.ethz.ssh2.Session; import ch.ethz.ssh2.StreamGobbler;) to run commands over an SSH connection (for test purposes it connects to my local machine). When I run my class as a standalone app it works, but ...
I'm looking around trying to see if anybody has asked this before. I don't think so. Some of the other questions I've looked at seem to talk about this a bit and indicate that using a JNDI datasource setup in Tomcat is the best way to do database stuff in your J2EE app now. It's been three or four years since I did any serious J2EE dev...
I am currently programming using Eclipse 3.4.1 and using the Apache 5.5 as backend server. I am also using the com.sysdeo.eclipse.tomcat_3.2.1 plugin for tomcat. I was just wondering, when I encounter an error and prints the stack trace for the exception. I always would see the line code where the error occured on the java work file gen...
Hello Everyone, I'm converting a standard Java Application that uses Spring Framework into a Web App. This application loads new Spring Context based on run-time parameters, that was done using ClassPathXmlApplicationContext/FileSystemXmlApplicationContext. So my question is how to do the same in a Web Application given that I already...
Hey All, I generated a Soap Service from a WSDL and now I need to deploy it to my existing application which uses embedded tomcat (I.E. I have a class which extends TomcatServeletContainer and a main class which instantiates that class and starts the server). I see many examples for how to deploy an axis service to a standalone tomcat ...

I'm using Tomcat 6.2 and Spring MVC 2.5. I've noticed that, whilst a user is logged in I can restart Tomcat and the user is able to continue browsing without re-authenticating. This appears to be coming from Tomcat's ability to persist sessions across restarts. It appears, however, that these persisted sessions do not make it back into ...
I have a web application "quicker" deployed in Tomcat5.5 version. Usually, I run this application by using url, localhost/quicker and it loads the index.jsp file which is the home page of application. I would like same application to be run using url, www.local.dev.mydomain.com/quicker. Would it be possible by doing some configuration in...
I have a webapp deployed to three servers running Apache, Tomcat and a load balancer in front of them. Now I am thinking of clustering them. Here are the options usual options and my constraints that I am aware of: Serialization based Session clustering: In my case, the application uses a lot of objects in session. So I would prefer n...

Hi, Has any of you managed to generate Clover reports successfully for web-apps on Tomcat or any other web server? ...
I'm developing servlet filter intended to manage some resources which should be available during servlet processing. Since I'm not very familiar with the Tomcat, I have some doubt. Is it guaranteed that, for single request, all attached filters and the servlet itself are processed by single (and the same) thread? In other words: can I as...
I am using eclipse Galileo. The "New Server Runtime Environment" dialog box contains three fields: Name Tomcat installation directory JRE I would like to set the tomcat installation directory relative to an environment variable I have set in my OS (win xp). Can this be possibly done? ...
For a limited time, we have to serve the same Tomcat 6 web application from two different domain names. Both domains need to be served HTTPS - is it technically possible to handle serving different certs for the same app using connectors (or other method)? The other option (which we are trying to avoid) is to handle the cert delivery up...
