Re: banned
Good point, assuming that what Mark says is true, that he was fired, this is all bad. I recognize your need to ban people and if it helps improve the signal to noise ratio on this list, I'm all for it. I also recognize that we are all responsible for what we say here. Both the first time around through email and the second time around in the archives. But in this instance, Mark doesn't have only himself to blame. Someone sent his comments to his workplace and resulted in him being fired. I've worked will some major jerks over the years who wrote great code, slung great servers, etc etc. Just because someone's has unpopular views or is terribly annoying or extremely frustrating or whatever does not justify maliciously alerting their employers. This just leaves a bad taste in my mouth. All you need to do is to create a filter and individuals can ban anyone they want. The email to MD dept of elections is spiteful and childish and way more damaging to the struts community than any bigoted and/or stupid posts.

For the record, I'm not against an employer firing an employee for 'whatever' reason they deem fit. If they don't like the way you wear your hair, I think they should have the right to fire you if they want. (The public also has a right to know about it based on the use of the press etc). Now though I'm clearly not in the position to get fired anytime soon, I still think as long as I'm doing my job right and don't blame the company I work for, what I do in my leisure time is not my employer's business. Including my haircut, age, religious beliefs or whatever. What I sell are my skills, work performance and last but not least a significant part of my lifetime, but neither my soul nor my private life. In Germany, it's not quite that easy to get rid of someone who, lets say, just got older because of working for you. And I think this is just. Stealing silver spoons, including deliberately breaking company rules in terms of e-mail usage and the like is another issue. Personally, if I owned a company and someone was using the company email domain name to post on sites such as "swingers" or "transvestitepride," I think I should have right to terminate his or her's employment. What I have a problem with is ... 1) The inconsistency in what is protected. For example everyone today talks about "tolerance." But what does this mean? What it ends up meaning is "There are no moral absolutes so the only valid belief system protected is one that doesn't espouse moral judgments." But what about being tolerant to the idea that someone might feel otherwise? Why is state sanctioned secularism the only valid religion (and yes secularism is a belief system - a religion). It's sort of funny that those whom often claim to be the most 'tolerant' are often the most vicious when it comes to attacking someone that disagrees with their view of "tolerance." There are many views I could state that would get me labeled as being 'intolerant,' yet, somehow it's supposedly not offensive to state "All views on X,Y,orZ are equally acceptable." To me, and many others, that later position can be considered extremely offensive. Why is only one view (secular humanism) considered 'non offensive' but other religious views are some how bigoted and intolerant. It's pure hypocrisy. In Germany, in a major part thanks to the US (I mean it!), religious freedom, for instance, is granted to everyone in our Constitutional Law (Art. 4 GG). Getting fired just because of one's religious views is impossible by law. So I, who believes in Jesus Christ as my personal saviour and follows the Bible as his above-all-worldly-wisdom guide can happily work together with Hindus and common atheists, in- cluding my boss. I can even tell them if they're on the road to eternal doom, the same as they may tell me I'm ridiciously wrong, and still keep my job. And in fact, the Bible is quite intolerant when confronted with modern secularism, but what's my choice? As for general opinions and secular beliefs, we have Art. 5 GG which grants freedom of speech. So there's no need for hypocrisy here at all. On the other hand, I definitely never would use a company e-mail address for anything other than business communication, and whoever deliberately chooses to do otherwise may just have to face the fruits of his dauntness. Or his dumbness, if you will. 2) Someone taking the time on the list to 'complain' to someone's employer. Sure you have the right to do so, but I think it's lame.

Re: [OT] how to calculate the size of an object
If you run this from a simple console test app, the JVM won't allocate any
extra objects between 2 and 4.
Unfortunatly, this is the most exact way to find out memory usage
(serialization size doesn't necessarily mean in memory size).
Just wait til those slackers at Sun at a Object.sizeof() method in jdk1.9 or
something lame.

hi,
Thanks for the link but this is very naive way of doing it. I am leaving it
to the mercy of gc.
What this method is doing
1. run gc() manually (AND hope it wont run automatically again soon.)
2. free memory
3. create and object.
4. free memory
and now just wish that JVM wont allocate any memory in it's heap between
steps 2 & 4. so that one can assume that whatsoever output comes belongs to
my object. I am at something better.
Jim you are absolutely right, this technique may return a negative number.

I need to know *the size of LDIFData object* at runtime. How to do that?
Well the class structure is something like this

String filename;
long lastLoadedTime;
}
public class Card{

RE: Theoretical debate
I think struts' concept of separating your actions from your data is
admirable and should be followed. The concept of your value/transfer objects
(basically the form) also having business logic sounds acceptable at first
but rapidly becomes a nightmare when you try to use the same value/transfer
objects in multiple processes.
I think it's a generally accepted practice that separating data from logic
is a "Good Thing"(tm).

calls methods on them. Why have an ActionForm or have to create all of
these Actions that are simply getter/setter adapters? Please don't be too
quick to retort to my supposed anti-struts mindset, but there are other
frameworks out there that allow direct interaction with my business objects
and don't require a heck of a lot of framework specific coding.
---
Example:
To have a multi-page form with JSF, I just create a bean that sits in
Session scope that has a series of getters and setters. JSF will also
allow
me to pre-set relationships to other objects at creation time. Then, when
I'm ready to submit the multi-page form, I just put in the jsp
#{myFormBean.submit}. No action mappings, only a managed bean entry.
With Struts, I have to create an ActionForm objects (can't just use a
business object I already have), and then create separate Action objects to
manipulate that ActionForm.

Subject: Theoretical debate
Last night I was Googling for something and I stumbled across the Crysalis
framework. I was actualyl intrigued by the underlying premise of it and I
wanted to see what others thought about it.
In a nutshell and in my own words, Crysalis
(http://chrysalis.sourceforge.net/) has the underlying idea that when you
develop in most MVC frameworks, Struts chief among them, you are actually
doing something unnatural and in a way at odds with basic OOP design.
Think about a shopping cart example... If you were going to write that in
straight Java, not for the web or anything, how would you model it? Most
likely you would have a ShoppingCart class with a number of methods in it,
things like addItem(), removeItem(), totalPrice(), etc.
In Struts, although you aren't FORCED to, what you GENERALLY do is create
three different Action classes like addItemAction, removeItemAction and
totalPriceAction, and each is called in response to a form submission.
But isn't it kind of odd that your object model isn't following what you
probably think in your head is the right way, i.e., one class with multiple
related methods? Proper encapsulation and all that jazz, right?
Well, Crysalis does just that. It's controller elements are regular Java
classes with multiple methods. What you wind up with is something that
resembles Remote Procedure Calls instead of numerous servlets as
controllers.
In other words, you would create the ShoppingCart object just as I
described
above, with all three methods. Then, when you submit a form, the action is
something along the lines of "ShoppingCart.addItem.cmd". ShoppingCart is
the class to execute, addItem the method and cmd is a suffix to direct the
request, just like extensions in your Struts apps map requests to
ActionServlet.
The elements of the submitted form are treated as the parameters of the
method being called, making it rather elegant.
I haven't gotten into any real detail on Crysalis, but I was interested in
getting other peoples' thoughts on the underlying principal (which I
*THINK*
I've stated properly!). It was rather interesting to me because I'd never
reall considered looking at it that way, and certainly it's not the way you
typically approach a Struts-based application. It was also interesting to
me because I've for about four years now been preaching here at work that
we
should write our applications as a collection of services that are executed
to form a coherent larger application, which is very much along the lines
of
this (so I guess I actually HAVE looked at it this way in a sense, but not
exactly).
Any thoughts?
Frank

Re: Storing global data in the servletContext
OK, that makes a bit more sense. I guess I got thrown by your "It sounds like you are the use case for EJB!" statement that I thought when you said bean in the next sentence you meant EJB. Also, I believe that some application servers will cluster the servlet context along with the httpsessions.

I wouldn't go that far -- but then again, I'm not much of an EJB developer either. Never needed 'em. What's the advantage to this technique? It's shared between clusters, and the ServletContext is not. That was the original question -- how to share things that are "application scoped" in a clustered environment. Looking back at the original email, I would guess that the things read from XML config files could pretty safely be stored in each ServletContext -- assuming they don't change after initialization -- drop down menus seem to fit that description. My other statement, about "using one bean to manage everything in an application context" certainly didn't mean one *enterprise java* bean. Like I said, I don't use 'em. But if you have a bunch of things that go into the application context, you may find it cleaner to make one "Application" bean which goes into the application context and which stores all those other things as properties. Then you never have to worry about making sure all accesses into the context use the right name, except for one object, and you get type-safety as much as you want it, and you have a clear interface for your application object which you could use in testing, etc. Joe -- Joe Germuska[EMAIL PROTECTED] http://blog.germuska.com "Imagine if every Thursday your shoes exploded if you tied them the usual way.

RE: forwarding to a pop-up window
For your tag, set the target to a window name, then when you submit, call a javascript function that opens a new window with the same name. This will submit all the values from the current page into the targetted new window. I think you can also just do and it will submit into a new blank html window but you won't be able to set the size or the properties of the new window like you can with window.open().

I18N problems
I've got a site that we're trying to deploy in Japanese. We're using struts message tags everywhere with property resource bundles for all the labels and text. The only text that doesn't come from the resource bundles comes from the database. The problem is that IE doesn't display the text properly. When we don't set the content-type to UTF-8, the text from the database shows up properly but all of the text from the message tags shows up garbled. Also, if we put japanese characters directly in the JSP outside of scriplet tags, it is displayed as garbled in both the browser and view source. When we do set the content-type to UTF-8, all of the text from the message tags shows up properly but all of the text from the database shows us garbled (html tags are also screwed up because the browser thinks part of the Japanese is a "<" so instead of "" view source only shows "/a>"). We tried running the properties files through the native2ascii utility from the jdk to convert all the japanese characters to \u but IE treats that as the literal text and tries to display "\u". We need to get both the message tag text and other text to show up properly as japanese. Has anyone else experienced this problem? If so how did you solve it? Thanks, BAL _ Tax headache?

RE: Calling one action from another - removing request parameters
Note that redirecting is less efficient than forward as it involves a
additional http response and request. So forward will be faster and less
processor intensive.

If you forward between actions without actually redirecting the browser,
then the parameters remain intact!
If you set redirect to true, then the request will be redirected at the
browser level, and parameters will be cleared.

Subject: Calling one action from another - removing request parameters
Hi All,
I am having a small problem with Struts. If my application calls say
something1.do?row=10 and the result of this calls another action servlet
ie something2.do with no request parameters, something2Action is still
able to see request.getParameter("row").
Does anyone know why is this happening and is there a way of fixing it?
Thanks!
