Is DiskFileUpload.java missing from Struts src ?
I've been trying to compile struts source and get a missing class error for class DiskFileUpload being used in CommonsMultipartRequestHandler.java in package org.apache.struts.upload.

Can you explain how this was done in a little more detail, particularly what methods were used, where they were used etc..? I have the current arrangement where I extend Action with a BaseAction, which implements my common method (the one to be called always) and then from subclasses of BaseAction.execute() I call the common method. It is this having to manually call the common method I would like to eliminate and just have it transparently occur higher in the hierarchy. As for your suggestion of using filters could you direct me to more information regarding that method I'm interested in exploring it.

Re: Login and security checks
What happens if you don't put a security constraint in the web.xml, but instead just specify a role in action in struts-config.xml?

Generating Java constants class from message resources
The most common approach I've seen to using error messages in code is set up
a bunch of constants somewhere and then use these in the code...
public class blah
{
private static int ERROR_CREATING_CLIENT = 1234;
public void doThis()
{
raiseError(ERROR_CREATING_CLIENT)
}
}
As Struts has an application resources file with all the error messages as
properties it would be nice if I could derive a bunch of constants from the
properties file so that I have one definition of the errors.
my idea is to write some code that will create a class that contains
constants based on the application resource file. This will allow compile
time checking of the error messages used in code.
So if the message resources file has
exception.clientexists=this client already exists
A class would be generated that has
public class messages
{
public static string CLIENTEXISTS = exception.clientexists;
}
And the code would
public void doThis()
{
raiseError(messages.CLIENTEXISTS);
}
Does anyone know of a better way of doing this? Has something like this
already been done?

HttpSession abstraction
This concerns the development of a session mechanism that achieves the same goal as the pattern where an ActionForm implements an interface that abstracts the Struts layer for the Model layer to use. I'd like to be able to use session data in the model layer in the same way I use form bean data. Since there is no HttpSessionWrapper class, I guess I'll have to get the attribute names and iterate through them passing them into some DynaBean...

IBM ServletManager vs Struts

RE: [OT] IDE with easy tomcat upgrade?
Netbeans is not easily upgraded as new Tomcat releases become available and the Swing environment can be burdensome and buggy unlike SWT (which is what eclipse is built on). Eclispe via the Sysdeo plugin does a great job and allows you to upgrade your version of Tomcat at will. Heck!, they have plugins for just about every server out there (http://eclipse-plugins.2y.net/eclipse/index.jsp). Eclipse may be weak on the JSP support but that will be coming along soon (see: http://www.eclipse.org/webtools/main.html). All in all Eclipse is more intuitive. Also, I am not speaking from religious prejudice. I was a long time user of Netbeans and ardent defender against Eclipse. But, Since Eclipse 2.x things are much better. The future of Eclipse is only looking better. The version 3.0 M1 build is already out. Anyways, I know several developers who have made the switch to Eclipse.
