Re: [Newbie] Is it worth subclassing your own Action and ActionForm classes to attain code re-use?

My application allows a user to make various different types of bookings for a (fictional!!!) hospital and logs them in a database. Each type of booking has a set of common properties but also different ones depending on the type of booking being made. I have divided my classes into a BookingAction and BookingActionForm superclass and subclasses (such as AmbulanceBookingAction and AmbulanceBookingActionForm) because I anticipate creating other subtypes of BookingAction that use the same properties in the BookingAction class but not in the AmbulanceBookingAction subclass. This initially seemed to me to be in keeping with programming for code re-use and extensibility. My problem with this is, if a user submits a form which posts its data via the ActionServlet to the AmbulanceBookingAction subclass, how would I ensure the BookingAction class did its stuff? Would it be better / easier to use separate, non-derived (from my superclasses) Actions and ActionForms to handle each type of booking and not subclass BookingAction and BookingActionForm (even though I would be repeating the some of the same properties common to each different type of booking)? I am concerned, though, not to lose points for not reusing code. It just seems to me, though, that trying to divvy the handling of the form data via inheritance is too complicated and / or unnecessary. In what circumstances might you want to subclass your own Action class and, if you did, how would you handle/inherit the form data? Would you just use different subclasses of your Action but just one ActionForm for each Action? What is the best way for me to implement this problem? (Or have I answered my own question?! ;0) ) Thanks for indulging me!

At several projects I needed a struts based browser back mechanism or a subcall mechanism. In both cases you have to store the last request (with request parameter) an restores it. Subcall means: From different contextes I navigate to the same site. To increse usability I will the user let go back to the context he comes from. I have written a BaseBackAction which all actions must subclass. This base action saves the requestpath and pushed it on a stack. To go back you have to implement a back-path in the struts-config.xml like action path=/back type=org.mwolff.struts.actions.BackAction/ The BackAction pops the path from the stack and forwards to it. The stack is limited to n entries, 10 default. If no back is possible, the BackAction forwards to the same path, where it calls from. Only actions that subclass from the BaseBackAction can use this automatic mechanism. So there is a second mechanism to register if you don't use this base action. The whole documentation is on http://www.manfred-wolff.de/struts/articles/HowTo-Back.html There you can also download the two classes. Improvments and suggestions are welcome.

Re: Database pool full.
I'm backing up what Max said about having a leak somewhere. We used to have
a lot of problems with pooling. We have about 50 database utility beans that
get a connection, perform action on the database then release the
connection.
We discovered that the leak came from one single method that didn't release
the connection. Once we corrected it, there was no more problems no matter
which scheme we use.

Subject: Re: Database pool full.
My guess is that you have a connection leak somewhere. Does this problem
start occurring immediately, or does it only show up after visiting a
number
of pages in the site?
Various db pools have different ways of dealing with no connections
being
available. Often, you can configure which strategy to use. Here are 3
different strategies:
1. Wait until a connection becomes available.
2. Fail if no connections are available (i.e. return null or throw an
exception).
3. Grow the pool temporarily if there are no free connections.
It is clear from the errors you are getting that your pool is currently
using strategy #2. I like #1 the best, because it is less likely that
requests will fail under load. But, you must be sure that you don't have
any
connection leaks, because the app will eventually hang if you have
connection leaks and use strategy #1. Strategy #3 works, but you can run
still run out of connections in the database itself, so it can start to
act
like strategy #2. This is one aspect of connection pooling that
important
to
consider when developing web apps.
But, it seems likely that you have leaks somewhere. Some of your
requests
are probably not returning their connections to the pool. It could be
that
you have exceptions that are being thrown and not releasing the
connection,
or it could just be that you have non-exception logic paths that don't
return the connections. Some combination of code reviews, debugging,
etc.
is
needed to track them down.
Another thing to watch out for is requests that require more than 1
simultaneous connection. For instance, consider the situation where you
have
a pool of 30 connections, 15 request handler threads, and a request that
requires 3 connections. If 15 of those requests come in at once, and
each
request handler thread grabs 2 connections, you will have deadlock as
all
the request handler threads wait forever for a third db connection to
become
available (assuming you are using pooling strategy #1 above). The
solution
to this problem is to make sure that you don't have any requests that
require more than one simultaneous connection, or at least that your db
connection pool has enough connections to survive a flood of connection
hungry requests (e.g. have a pool of 45 connections in the example
scenario
described above -- 3 conn/req * 15 threads = 45 connections in the
pool).
This may seem unlikely, but it is a problem I have faced in a production
system (and it wasn't easy to track down!). Another lister here
suggested
a
good technique for ensuring that none of your requests require more than
1
simultaneous connection -- test your app with a pool of 1 connections.

my version of the Tokens
Hi,
before knowing about tokens, I have implemented a way to deal with the refresh of a
POST form problem. Now that I know that tokens exist, I can't really use them for
several reasons, but mainly because it adds a field in the form which modifies my
current form validation with javascript.
Here is what I have done in my ActionBase class, that every Action I use derives from :
protected void setDBFlag(Object o, HttpServletRequest request) {
synchronized(session.getId()){
request.getSession(false).setAttribute(
Parametres.DB_FLAG + o,
Parametres.CHECKBOX_TRUE);
}
}
protected void clearDBFlag(Object o, HttpServletRequest request) {
synchronized(session.getId()){
request.getSession(false).removeAttribute(
Parametres.DB_FLAG + o);
}
}
protected boolean checkDBFlag(Object o, HttpServletRequest request) {
synchronized(session.getId()){
return (
request.getSession(false).getAttribute(
Parametres.DB_FLAG + o)
!= null);
}
}
These methods should be called from the class below this way :
public class MyAction extends ActionBase{
...
protected ActionForward executeUpdate(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response)
throws Exception {
if (GET.equalsIgnoreCase(request.getMethod())) {
setDBFlag(this, request);
this.processBeforeUpdate(mapping, form, request, response);
return mapping.findForward(EDIT);
}
else {
HttpSession session = request.getSession(false);
ListResultCsv resultats =
(ListResultCsv) (session.getAttribute(attTable));
if(checkDBFlag(this, request)){
//update DB
processUpdate(...,form);
updateBeanConteneur();
clearDBFlag(this,request);
}}
}
.
}//end of class
As you can see I'm putting a flag on the session. This flag name is actually function
of the name of the Action instance itself (this).
The idea is to put the flag to true while preparing the form, then when the form is
submitted, I check if the flag is true then I do the updates and set the flag to
false. So when a user presses refresh, the form is not submitted 2 times.
The problem with this solution is that I must use the same Action to prepare and
submit the Form, but it's the case most of the times.
I was wondering if the solution I chose looks OK in a multi-user application. I know
that each user has its own Action instance, so it should not be a problem, but at the
same time, looking at Struts' implementation of the tokens which is more complicated,
I think there might be some issues with my approach.
Thanks in advance for the feedback!

Re: my version of the Tokens
Thanks Adam for your comment.
Yes you're right... but in my application every new window I open is indexed
with a windowId.
In fact, every session attribute name is built using this windowId, so that
session objects don't mix between pages. The flag itself uses the windowId
this way, but I didn't put it in the code (something like
request.getSession(false).setAttribute(Parametres.DB_FLAG + o +
getWindowId(request), Parametres.CHECKBOX_TRUE);
Nonetheless, the problem you found will happen if the user decides to open a
new window by himself because the new window will have the same windowId as
the previous one :(

Hi Raphaël
what happens if the user has two browser windows open for two different
datasets which use the same action? He will be prevented from submitting
the second one.

Subject: Using map backed forms beans
Hi,
When I use an ActionForm which have a HashMap to store values as
specified in chapter 4 of the users guide, the name of the text field is
not
properly displayed. My code is given below.
ActionForm
private Map map = new HashMap();
public void setMap(String key,Object value){
map.put(key,value);
}
public Object getMap(String key){
return map.get(key);
}
in JSP i use this coding.
html:text property=map(name) size=15 maxlength=25 title=User ID/
When it is displayed on browser the name is displayed as map(name). I want
it to be just name. (It is simple example. I need dynamic generation) How
to
do it.

Re: tokens creating a field in my forms
OK, I was thinking the same thing. Referring to fields by id is better but less convenient when all your fields are accessed by maps therefore their names is something like formProp(Foo.foo.fooo). - Original Message - From: Adam Hardy [EMAIL PROTECTED] To: Struts Users Mailing List [EMAIL PROTECTED] Sent: Friday, November 21, 2003 10:48 AM Subject: Re: tokens creating a field in my forms On 11/20/2003 11:44 AM Raphaël di Cicco wrote: I understand how tokens work.

Hi Raphael, without looking at the source code I can't definitely say that it is impossible, but it is highly unlikely. Technically speaking you would be better off referring to your fields in javascript by id, rather than by index, since this situation with tokens is not the only one that will give you this problem. However I realise this will not be helpful to you if you have already finished the javascript code!

Re: ArrayIndexOutOfBoundsException after resubmitting form
Here's one thing I do to avoid resubmitting. I put a flag on the user's session to tell whether or not he already has done the transaction : On preparing the form put the flag to true. When submitting, verify that the flag is at true, if so then do the update in the database and put the flag to false. The form won't be submitted again unless the user decides to go to the form page again. For the flag name I usually use the Action instance name, so when i'm in the Action class I do session.setAttribute(this, true); Raphaël - Original Message - From: [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Friday, October 17, 2003 9:31 AM Subject: RE: ArrayIndexOutOfBoundsException after resubmitting form May be in the reset you have emptied the list..

Here is a description of the problem: My intention is to use transactional tokens to prevent duplicate posting of a form where a user deletes a row in a list of search results. After the delete is successful, I use the browser's back button to return to the list of search results and attempt to submit the request to delete the same row again. At this point, an ArrayIndexOutOfBoundsException is thrown (the exception stack trace is provided below). After examining the debug log statements, it appears that the logic to validate the transactional token in the action has not yet been reached. The debug log statements indicate that the form's reset method is invoked and the getter for the list is called, but that is where it fails. The Struts logic is attempting to go past the last valid index in the list and I have not found a way to catch this nor prevent it. If anyone has any ideas, it would be much appreciated.

problem with forwarding to input from the method validate
Hi, I'm working with Struts 1.1 and tiles. It seems like the validate() can't forward to my tiles page when an ActionErrors occurs. Here is my struts-config.xml file : action path=/EditDossCEAction type=com.atosorigin.agrippa.web.communs.doss.EditDossCEAction scope=request name=EditDossCEForm attribute=EditDossCEForm input=page.communs.editDossCECarte validate=true forward name=edit path=page.communs.editDossCE / forward name=editCarte path=page.communs.editDossCECarte / /action When my method validate on EditDossCEForm fails it returns a non null ActionErrors and this is supposed to forward to the input page. The RequestProcessor seems to find page.communs.editDossCECarte as the input, however it fails in finding the corresponding tiles definition ( mapping.findForward(input) is null) and therefore forward me to the correct page. I solved this problem by adding this forward : forward name=page.communs.editDossCECarte path=page.communs.editDossCECarte / Was anyone aware of this problem ? Any other way to solve this ?
