apache to tomcat: mod_jk vs mod_proxy
What are the advantages and disadvantages of using *mod_jk* and *mod_proxy* for fronting a tomcat instance with apache? I've been using mod_jk in production for years but I've heard that it's "the old way" of fronting tomcat. Should I consider changing? Would there be the benefits? thanks ...
Is it better to keep libraries in the application lib or in common/lib?
I'm doing some Spring development and I'm trying to decide if libraries should always be kept in the application lib, even if they end up being common to more than one app. Doesn't Tomcat startup slowdown if a bunch of jar files end up in the common/lib? I'm also fearful of versions and dependencies. Isn't that less of a problem if the a...
Configure project in eclipse so that it ends up in the tomcat "common" class loader
I have two tomcat web applications that need to share information using a singleton. I have already made it work by placing the jared classes in the tomcat common directory. Each webapp then gets the same copy of the singleton. What I would like to do is to integrate this behavior within eclipse. I would like the common classes to be ...

Tomcat security constraint for valid user
I'm trying to protect a resource in tomcat so that only "valid users" (those with a valid login and password in the realm) can access it. They do not necessarily belong to a group in the realm. I have tried with many combinations of the <security-constraint> directive without success. Any ideas? ...
How can I detect which jsp includes a web page uses in a web application
Hi, I want to detect when an include in a jsp occurs in a web application and specifically which page is being included. I want to do this when the menu page is requested. One option is to overwrite PageContext but it turns out you can't access it anywhere to wrap it. As far as I can see PageContext is the only class which provides incl...
Tomcat deployment problem using jar file instead of classes
We're deploying a WAR file into Tomcat 5.5 and it works fine if WEB-INF\classes contains .classes files, but if we move the .jar file containing that .classes into WEB-INF\lib, we get an exception on runtime complaining that java.lang.NoSuchMethodError, but existing class file in .jar file contains the class and method does exits!

Java and tomcat vs ASP.NET and IIS
Until recently I'd considered myself to be a pretty good web programmer (coming up for 10yrs commercial experience on a variety of e-commerce, static and enterprise applications). I'm self taught and have always used the Microsoft product stack (ASP, ASP.NET)... My applications are always functional, relatively bug free, but have never...

How can you serve a dynamically generated file w/ Tomcat & Java technology?
Having a hard time figuring out how to send dynamic data to a web-app's user without having to create a file & using a dynamic link to static content using java technology.

Deploying a Spring-based WAR with its JAR dependencies externalized.
I have a Spring app that has a lot of dependencies (18 megabytes of JAR files..) - Now, when I am testing on the remote Tomcat 6.0 server, I'd like to not have to upload that 19 megabytes of dependencies, and just upload the classes. Pretty simple, right? I can't get the damn thing to work. I'm using Eclipse 3.4, and if in Java Build ...

Java web application to use for testing of servers
I'm looking for a simple open source, or reference application that I could use for testing some Java servers. The primary server would be Tomcat, and the database backend is MySQL. Are there some reasonable sample applications out there that are fairly easy to get up and running with? The ideal application would be fairly stateless in ...
Oracle - connection Pooling with spring framework
Hi, We are trying to implement Oracle connection pooling with the help of Spring Framework. We are using DBCP connection pooling method. However the integration between DBCP and spring doesn't go down that well. Problem that we face is that DBCP returns PoolableConnections Object while Oracle expects OracleConnection Objects.
