RE: [OT] Re: [S2] Obtaining Session/Request Object
First off, I think the notion of sighting wikipedia as the end all be all of a definition is highly suspect. After all, anyone can change the Wikipedia at any time. For instance http://en.wikipedia.org/wiki/The_Colbert_Report#_note-34 "On January 29, 2007, Colbert cited the case where Microsoft was alleged to have hired someone [52] to tamper with Wikipedia..." I like all the responses that Google has for define:servlet. You may want to quote one of them for your answer. http://www.google.com/search?q=define:Servlet This does sound a lot like a homework question or an interview question.

"JSPs are compiled into Java Servlets by a JSP compiler. [1]" The way I see it, so long as the result is a JSP page, the project contains a servlet. Granted, one can easily write the viewer component without JSP, but I think its fair to guess that a large percentage of Struts projects make use of JSP pages. > A web application is any application that runs on the > web, like a blog, or web email, or social site, or > whatever. A blog, web mail or social site that was written in Java and runs on or inside a standard server such as Tomcat would be a servlet, though. As far as I can tell, it meets all the requirements. It sounds like, for any program (end point; excluding containers, such as Tomcat, Struts, etc) accessed via a browser, if it is written in Java, it is a servlet, otherwise its a web application. How about a solid clear definition of a servlet?

RE: Nested struts forms, dynamic allocation using javascript or ??
Something you might consider, the Date object not only contains the
time, but also the date.
Joda - http://joda-time.sourceforge.net/ - is a good API for time
structures. Far superior to the Date class in Java, because it has:
- LocalTime class that represents time only.
- Period class for representing periods of time
- others
I find that if the Business Objects are architected correctly the
presentation layer, the form, becomes self describing.
Hope I helped,
Big Mike

Hi folks,
I've taken more than a couple stabs at trying to do this and failed.
Miserably enough that I'm not going to even attempt to post my efforts
here.. they're really ugly.
What I'm trying to create is a form that folks that are not all that
computer literate can feel comfortable using to enter in events to be
added to a club's calendar of events. The first part of this task is
really straight forward in that I collect the name of the event, its
description and yadaydaydada...
Here's where it gets hairy and the idea of using nested forms came to
mind:
The events can have at least one day but can be over more than one day
with each day possibly having a different start time and finish time.
To that end I have a bean:
public class EventDayBean {
private Date start_time;
private Date end_time;
private Date event_day;
|
|
/* getters/setters follow **/
};
that will be included in the action form as a collection (ArrayList).
Given that each event will have at least one day I want to either
a) have a field where they user inputing the data specifies how many
days the event is and have some mechanism to (re)populate the nested
portion of the form (growing/shrinking the collection as needed) or
b) have a button that says "add day"
or ??
What I'm interested in here is input from those that might have
implemented such a thing as to what strategies are viable to solve this.
Thanks in advance for your thoughts

RE: Where is the Source?
You know that package naming is arranged like it is for a reason. I went to http://opensymphony.com/ on a hunch. Then found an XWork button on the left hand side column. It lead me to http://opensymphony.com/xwork/. There you can download zips that contain the source of multiple versions of their software.

OOM Error (Java heap space) from 1800+ form elements, am I doing something wrong?
A form of approximately 1800 form elements is causing "java.lang.OutOfMemoryError: Java heap space". When 1000 form elements are used, no such error. The environment: - JBoss 4.0.5 - Struts 1.1 - A jsp page using struts tags to start and end the form block. Then insidethe form, xslt is used to parse a 300 element xml document into 6 input tags per element. What seems to be happening, the reset method for the form bean is called. Then before any set methods are called, the OOME is thrown. Should I throw out (REALLY DON'T WANT TO) the xslt and use nested form beans properties? Any help would be appreciated.

RE: OOM Error (Java heap space) from 1800+ form elements, am I doing something wrong?
Posting to the group, since I believe a solution has been found. It appears that my issue was something like a buffer overrun in the jsp. A solution that we are testing is the following code snippet: <%@ page buffer="1024kb" autoFlush="false" %> The current size might be a little overkill but, my issue seems to have vanished. Thanks goes to my co-worker you pointed me in this direction. Thanks, also to the great support from this mailing list.

RE: submitting a form using java script on IE
>From my understanding the onSubmit="return true;" code just allows the
form to be submitted. See
http://www.htmlcodetutorial.com/forms/_FORM_onSubmit.html
I noticed in your pasted output, the "this" is removed from the anchor
tags. Could this be the issue?

Mike:
I tried this one too and I tried using getElementByID and I tried
document.all[frmName], they all worked fine. I was able to get the
object successfully under FF and IE. I view the contents of this object
using simple alerts and JS console in FF. The problem is when submitting
the form the event doens't go through. S2 adds the attribute for the
form (onSubmit="return true;") which is making things harder. It works
fine when using buttons to submit but with anchors it's not . :/
