Betreff: Re: Validator problem with integers
An integer validation is not the same as a are all
characters numeric
validation. I don't think the validator currently has a
numeric check but
patches are welcome.
David
Hi folks,
Using struts-RC2, when using Validator with a dependency
on integer validation, I have a problem with the validator
assuming that any integer starting with zero 0 is
necessarily octal. In one example, I have a form where
people enter phone numbers. Which is split up into 3 text
boxes. Area code, 3 digits, last 4 digits. A fairly common
way to break it up.
Here is the validation.xml entry for one such field:
field
property=dayPhone3
depends=required, integer, minlength, maxlength
arg0 key=Daytime Phone box 3 resource=false/
arg1 name=minlength key=${var:minlength} resource=false/
arg2 name=maxlength key=${var:maxlength} resource=false/
var
var-namemaxlength/var-name
var-value4/var-value
/var
var
var-nameminlength/var-name
var-value4/var-value
/var
/field
Numbers like 0897 will cause the ... must be an integer message.
Obviously it is not a valid octal number, and I know that the format
of these numbers would appear as an attempt at an octal number.
How do you prevent octal interpretation but still ensure that
the field is numeric? I'm being a tad lazy here, because I
know I could always write my own pluggable validator, but
I'd like to use what already exists if possible.

Re: Problems with an inherited getter in a derived bean
My friend, I must admit that I have never applied inheritance on static
nested classes in my life.
(Not at least that I can remember :) )
I'm not to sure what the minimal access control level for static nested
classes is from point of nested inheritance and Struts system.
Maybe it has to do something with like reflection process that it needs that
nested class public access. :)
No idea, maybe someone else can comment on this issue?
Quite interested myself to know the answer to this one.

Subject: Re: Problems with an inherited getter in a derived bean
thanks for confirming that this should work - one fact that I omitted in
my original mailing was that the classes were inner classes
i.e. it was the PostCode.Area class that is in the collection
public class PostCode
{
protected static class Pbase
{
protected String name;
public String getName()
{
return name;
}
}
public static class Area extends Pbase
{
}
}
I works it I change the access on the Pbase class to public, but do I
have to ? I thought that it was legal to have derived classes increase
the accessibility - I do not want to expose the Pbase class -
however this is pushing the limits of my knowledge about what should be
happening.

Subject: Problems with an inherited getter in a derived bean
In my struts application, I have a base bean with a set of basic
properties (e.g. name) and then I create various derived beans with
their own extra properties. I have a problem with the html:options tag
in that if I try to read a property that is inherited from the base
bean from a collection of the derived beans
i.e. I have a tag like this
html:options collection=CountyList property=name /
- I get an error saying
No getter method available for property name for bean under name
CountyList
and if I implement the getter in the derived bean the error goes away.
Is this known behaviour in struts - is seems like a bug to me (or
perhaps a bug in commons-beanutils?) Can anyone comment

Re: WAP/WML support to existing application
The simplist way would be just to have WML copies of your JSP's Something like this at the top of you jsp.. (i'll have to check but i think its correct. JSP's default to contentType=text/html) %@ page language=java contentType=text/wml % If you want to minimize repetitive markup between html and wml versions then some cunning use of tiles and a WML layout could do the job... But this would really be up to you. Having stuff too rationalized can make applications harder to maintain.. I'd add new views but use the same actions. The other option would be the parse the HTML version into a WML versions, personally I think that this is a little more elegant but would confuse maintainers more. . Youu could go for best of both worlds and do an XSL transformation at build time to generate the additional jsp's, but unless your site is huge this could take more time than this would warrant. 1 issue affecting WML from JSP. The only problem with WML versions and JSP is that a few of the original nokia wap phones (7110) have trouble with white space at the top of WML pages. I worked for an agency where the contact for one of their clients had one of these phones and it was a pain in the arse. I ended up doing all my WML as servlets because of the control over white space. You can replicate this bug with the original version of the nokia wap kit, the emulator has the same issue.

RE: Validator with LookupDispatchAction and Tiles

Having the repetitive definition blocks just doesn't seem right. If I (or another developer) go in to make any changes to the mapping, then I have three or more sets of mapping to analyze and possibly change. That just seems messy and prone to error.

Consolidating Actions and avoiding mulitple action mappings is cleaner and easier to identify functionality. Inevitably you have to come back to the app to make updates. When you do come back it's a whole lot easier to indentify an action according to it's operative functionality. The added advantage of LookupDispatchAction is also the i18n button naming, easier management of mulitple buttons in the same form and the translation of button names to appropriate method names. Agree with you. I am a little bit suspicious if someone still *complains* too many action mappings after being consolidated by the dispatch action for some reasons.

We are developing a web-app with multiple editors, each of which has a Selection page where the user decides to Create, Read, Update, or View the object supported by that editor. Each Action Class handles the CRUD functions for one object type and sub-classes LookupDispatchAction. We are constructing the pages using the Tiles framework. Now the fun part: We are implementing Validator. The client-side validation (javascript) works fine, but we have an issue with the server-side validation. When the validation fails, we should return to the page that had the error. I.E. When the user is creating and has a server-side validation error, we need to return to the create page, which is a tiles definition.similarly with the Update function, we need to return to the update tiles definition. The input tag in the action-mapping seems to be the answer, but it would require multiple action mappings to have an input tag for each of the tiles-mappings that used validator. My question: Is the input tag and multiple-action mappings the right way to accomplish our goals? The use of multiple action-mappings seems messy; is there a better way? Could you elaborate why you think the use of multiple action mappings seems messy? I am asking the question from a research point of view. Jing Thanks for any advice or thoughts.

Re: Validator problem with integers
Hi Brad,
use mask instead of integer. That should do the job. Error message
states, that the entry is invalid. BTW, arg1 has to be used both for
minlength and maxlength since {1} is the argument in the error message.
I found that mask can solve nearly all validation problems if they are
constrained to one field. If you have interdependent fields you still
have to go back and implement ActionForm::validate.
field property=dayPhone3 depends=required,mask,minlength,maxlength
arg0 key=Daytime Phone box 3 resource=false/
arg1 name=minlength key=${var:minlength} resource=false /
arg1 name=maxlength key=${var:maxlength} resource=false /

Form conception problem !!!
Hello all,
What I have to do is something like this:
table
logic:iterate id=object collection=myCol
tr
tdhtml:multibox property=ids value=%=object.getId()%//td
tdbean:write name=object property=name//td
tdhtml:text property=editableValues//td
/tr
/logic:iterate
/table
That means I have a check box that when it is checked, it returns me an ID
and I have the html:text.. that return me a string.
Actually, in my form, I have:
public class myForm extends ActionForm{
String[] ids;
String[] editableValues;
}
Problem is to do the relation between the ids selected and the values
edited... Actually it is done by the position is the String[]... I don't
like that and I would like to know if there is another way to edit this.
Hope you'll understand what I mean...
Thanks
Valéry

The validator actually goes by the ActionMapping attribute name, which by default is the formbean name. So you can have a base formbean, defined as an DynaActionForm, and then give it different attributes in each mapping. action name=baseForm attribute=loginForm action name=baseForm attribute=profileForm Then in the validator, you have have a form for loginForm and another for profileForm (if you need it). -T.

RE: Image cache problem
Hi David, I think it has nothing to do with browser versions, I think this is only caused by caching settings. You must realize that caching can occur both in browser cache (configure this using Tools-Internet Options-General-Temporary Internet Files-Settings) and in proxy server cache. You should force your createimage.do to be non cachable. (Instruct proxy servers and browsers to always retrieve a fresh version) You can achieve this by setting a HTTP header: response.setHeader(Cache-Control,no-cache); see the javadocs for more on the setHeader method of the response object. See http://www.mnot.net/cache_docs/ for a very good tutorial on caching.

In the situation I describe I want two forms to be submitted to the search action *at the same time*- one representing the currently entered details of the booking one representing the entered search criteria.

I want to use struts forms for both the booking data and search criteria so that when the view is created the previously entered values are preserved - that is one the things struts is doing for me (isn't it?) Does that make sense? Is there an alternative to creating a 'super form' containg the 'real' data and the search criteria data? Or do I just not get it? thanks, Paul From: Ted Husted [mailto:[EMAIL PROTECTED] snip HTTP only allows you to submit a single form.

The booking view allows the user to book a number of tickets for one show. It has fields for Customer, Performance, number of tickets free text remarks. The Customer Performance fields each have an associated serach button. If the user presses the 'Performance Search' button then the view is redrawn showing the booking details already entered on the left and a Performance Search 'pane' on the right. The search pane includes criteria such as 'show', 'venue', 'time' etc. And a 'search now' button. Pressing the 'search now' button brings back, in the search pane a list of matching performances. Clicking on a performance in the list populates the performance field in the booking pane.

RE: ActionForm 'reset' method being called when JSP is rendered
Ted, After I sent the original e-mail I found out that one of my developers had changed where the ActionForm was initially instantiated. The first JSP is calling an Action (via a html:link/ that does NOT have an ActionForm associated with it. This Action preloads a series of JavaBeans and then forwards to the second JSP. The Action associated with this JSP does have the ActionForm associated with it, and since the ActionForm has never been instantiated, the html:form/ tag was doing it at that time. I guess I never realized that the html:form/ tag would do this (instantiate an ActionForm and call reset) - I've always been under the impression that the ActionForm, reset, and validate methods were not called until AFTER the form was submitted. Learning something new everyday . 8-) Thanks.

jstl parseDate question
Hi, I read various threads in this newsgroup about getting a Date from a jsp page into a bean. Now I'm converting a String value into a Date value in an Action. But there is a JSTL tag fmt:parseDate that should be doing this. But nowhere in the documentation can I find a small example of how to do it. Is it possible to parse user input to a date object using fmt:parseDate or is it only for parsing Strings to date used in the page itself?

You must realize that caching can occur both in browser cache (configure this using Tools-Internet Options-General-Temporary Internet Files-Settings) and in proxy server cache. You should force your createimage.do to be non cachable. (Instruct proxy servers and browsers to always retrieve a fresh version) You can achieve this by setting a HTTP header: response.setHeader(Cache-Control,no-cache); see the javadocs for more on the setHeader method of the response object. See http://www.mnot.net/cache_docs/ for a very good tutorial on caching.

For the sake of clarity, I'll call this retrieveDataAction. retrieveDataAction gets the data and places it into session scope under key 'GRAPHDATA' the user is then forwarded to displaydata.jsp. displaydata.jsp contains the following (simplfied): logic:present name=GRAPHDATA scope=session phtml:img page=/createimage.do //p /logic:present The createimageAction retrieves the GRAPHDATA from session scope, generates a gif image and writes it to response.OutputStream(), closes the stream and returns null. The problem I have is that at least one client (using IE 5) finds that the same image is always presented even though he has requested some different data. I have not been able to reproduce the problem using an IE 6 client - does anyone know if this is an IE 5 'feature' and - is there a solution?

Re: iterating thru a collection
Not to sure what is required here but for populating a select box options
with values and labels
I just create a java.util.List of beans.
e.g. Category bean
public class Category {
protected int id;
protected String name;
// getters/setters
}
Now you just load the List (e.g. categoryList of type java.util.List) into
the options/options tag specifying the value and label that will be
pulled out of the beans in the List. (e.g. value=Category.id;
label=Category.name)
something like that...:)

Double log output from commons-logging with log4j
Hi folks,
I'm hunting for some time the cause, why I get double output lines from

//
Log log = LogFactory.getLog(this.getClass());
if (log.isDebugEnabled())
{
log.debug(User +userid+ logged on);

design issue MVC - forms, EJB, data marshalling
I am starting a new app and trying to work out the best design approach. At the moment I want to get the app up and running, and so I'm just going to use tomcat and struts and achieve MVC by seperating out the database access into factory classes. At some point after I've got the project running, I want to replace the factory layer with CMP entity beans in JBoss (mostly for the learning experience). I've read Mastering EJB by Roman et al and so have a newby's idea of what the benefits would be although I'd like to hear what some gurus out there who've got experience with CMP say. My doubts are about whether entity beans can handle what I want to do. After I finished a successful project (not using EJB) which handled data-intensive lists with nested tags, I'm thinking of pursuing that design paradigm further. The value beans were created in the factories and passed into the action forms for use by the nested tags. The value beans had a validate() method, which took a Locale as the parameter when necessary, e.g. for date validation. Now I'm not sure if I can use the same principle in EJB. Can I take an CMP entity bean out of the J2EE container and use it in a struts form? And the reverse - can I pass a bean back again with updated values?

I'm trying to implement search functionality on the same page as the view's primary function. I think an example would help... Consider a simplified ticket booking system. The booking view allows the user to book a number of tickets for one show. It has fields for Customer, Performance, number of tickets free text remarks. The Customer Performance fields each have an associated serach button. If the user presses the 'Performance Search' button then the view is redrawn showing the booking details already entered on the left and a Performance Search 'pane' on the right. The search pane includes criteria such as 'show', 'venue', 'time' etc. And a 'search now' button. Pressing the 'search now' button brings back, in the search pane a list of matching performances. Clicking on a performance in the list populates the performance field in the booking pane. It is also possible for the user to enter remarks, whilst using the search function without losing those remarks. The Customer search function works in a similar manner, and is displayed in place of the performance search when in use. With me so far? (thanks for reading). Working under the assumption that I can't submit two forms (the booking the search criteria) to a single action (the search action) I have come up with the following implementation: I have a single form containing all of the booking fields and all of the search criteria fields, with the view generating a different single html form definition depending on which of the search 'modes' should be visible. This seems to work ok. A second requirement is that these 'search functions' be resueable on other views. To this end I have defined the search fields in my form class via a map (so that I don't need to redefine the form class, just to add a new search criteria). I intend to wrap up the display logic in some custom tags. Is this is a sensible approach? Or is there a simpler way? Ideally I'd like my generated html to include multiple forms - one for the booking and one for the search, but if I do this then how do I send my booking form search form to the search action (so that the page can be redrawn with any modified booking details preserved?

Subject: Re: Problems with an inherited getter in a derived bean
Hi,
Just for fun I set up a little test app. It demonstrates that the bug
is definitely in Common Beanutils. Normal Java relfection can call a
method derived from a protected nested class without problems. The
problem seems to be in o/a/c/b/MethodUtils.java : line 442ish where
Beanutils checks the declaring class to see if its public - it should
probably check the derived class instead ie clazz = method.getClass()
-MethodUtils.java - getAccessibleMethod(Method method) -
// If the requested method is not public we cannot call it
if (!Modifier.isPublic(method.getModifiers())) {
return (null);
}
// If the declaring class is public, we are done
Class clazz = method.getDeclaringClass();
if (Modifier.isPublic(clazz.getModifiers())) {
return (method);
}
End--
As far as your problem goes the simplest fix seems to be write a public
getName() method in Area and in its implementation call super.getName().
The alternative is to fix Beanutils (I haven't checked bugzilla so this
might even be a recently fixed bug). I'm cross-posting this to
commons-dev to confirm that it is a bug since I may look at it a bit
furthere and write a patch next week if I have the time.
Paul- Hope this helps
Alan - Hope this is of interest

dynamic properties
I am still fairly new to java and struts so please forgive me if this questions doesn't make sense. I am wanting to dynamically change paths to files, images, css, etc based on the url used to access the site. For example, if a user enters the site via abc.domain.com, I would like the paths to images to be something along the lines of /images/abc.domain.com/image.jpg. I'm sure there are many ways to accomplish this, but I was trying to find a way to perform this within the struts framework. Possibly by dynamically using different property files? Would this make sense? Is there be a better solution? Maybe a filter of some sort? Has anyone tried to do something similar? Any guidance is greatly appreciated.

Re: ActionForm 'reset' method being called when JSP is rendered
I am writing an application with a series of wizard type pages, so I thought that I would use one big ActionForm in session scope and each page add extra information to it - however this did not work as reset was being called at each page invocation - I am interested to hear that reset should only be called at instantiation time, because I believe that in 1.1 RC2 it is being called more often than that - I can did out the old verision of the code to have a look at the exact circumstances if necessary Ted Husted wrote: In Struts 1.0.2 and later, reset is called by the html:form tag *if* the ActionForm is being instantiated at that time. The scope shouldn't matter. Also remember that the html:form tag is looking at the Action to which it submits, which may not be Action 1. If these are the same Action, or share the same formbean under the same attribute, then the ActionForm should already exist, and reset should not be called. -Ted.

Re: FileNotFoundException when creating FileInputStream
FileInputStream expects a filename, but you fed it a URL. Is the XSL file within your webapp? If so, don't use a URL to reference it. If it is not within your web app but it is under your control, consider moving it into your web app. If you cannot move it, you will need to make an HTTP request to go get it. This code will go get it and give you an InputStream to read from (there may be better ways -- I just hobbled this together): InputStream in = new StringBufferInputStream( new URLConnection(new URL(myXsl)).getResponseMessage() ); This is expensive, so if you need to get this often and it doesn't change much, you should cache it within your app. Be sure to consider what a reasonable cache strategy would be, though. If you just get it once and hold onto it forever, your app will need to be restarted every time the xsl file changes, which would not be acceptable in a production environment in most cases. -Max - Original Message - From: douglas reames [EMAIL PROTECTED] To: [EMAIL PROTECTED] Cc: [EMAIL PROTECTED] Sent: Thursday, June 19, 2003 5:43 AM Subject: FileNotFoundException when creating FileInputStream When I attempt to open an XSL file to complete a transformation, I get the exception FileNotFound.

Note that the same entity reference in web.xml works fine (i.e. it looks for barfoo.xml under the appropriate context's WEB-INF directory which is where I would expect a relative reference to be relative to). Using an absolute reference for the file isn't really a solution because the environment this app has to run in is a mix of linux, windows and solaris. (i.e. C:\\foo\\bar\\tomcat\\webapps\\foobarcontext\\WEB-INF\\barfoo.xml won't work on all platforms that is has to work on.). While not an exact solution to your dilema, why don't you just use multiple config files? I'm not entirely sure what you mean by this, it might only be available in struts 1.1. The problem we have at the moment is that we have multiple web apps that share a bunch of common struts (and tiles) configuration. Rather than having multiple copies of this shared configuration in various config files I'd like to have on copy of the shared stuff referenced by the various config files. Yes, I undertand your requirements. There are patches available to enable backward compatibility to Struts 1.0. See http://jamesholmes.com/struts/ for complete details. Should you choose to use the Struts Console (also available from that same url), it doesn't work with entity refs. That's one of the items standing in the way of supporting OJB configuration in the near future. Good luck with whatever you choose. I've just had a look at the url you mention above and it does seem to indicate that entity refs in the struts config files should work. Before I go patching to get multiple config files to work with 1.0.2 I'd like to get to the bottom of the problem I have using entity refs. We're not using the struts console so I'm not too worried about breaking that. The problem that I have is that entity refs are relative to tomcat bin rather than the context's WEB-INF.

Action class time out logic
Hi Guys:
I have an action class that delegate to the business layer for
processing. Sometimes it takes a long time to do the processing. I would like
to have a timeout of say 2 minutes, I couldnot implement the timeout in
the jsp page, because it is the action class which is doing the
processing logic and until the execute method returns, the jsp is never
executed. So How could i implement the time out in the action class.
I tried to implement a timer using the timer class. but still it
doesnot work, the response is not flushed until the execute method returns,
that means the time it take to finish the processing of the business
logic.
-- code for timer--
new TimerTask(){
run()
{
System.out.println(timer ended);
ActionErrors errors = new ActionErrors();
errors.add(ActionErrors.GLOBAL_ERROR, new
ActionError(error.timeout));
if (!errors.isEmpty())
request.setAttribute(Globals.ERROR_KEY, errors);
try
{
PrintWriter out = response.getWriter();
out.write(timeout);
out.flush();
//response.sendRedirect(request.getContextPath());
//response.flushBuffer();
System.out.println(send to browser);
}
catch(IOException ex)
{
System.out.println(IO EXCEPTION);
}
}
}
even though i did write something to the response stream, the response
is not send until the execute method returns. any ideas why?
I believe someone might have done this and could help out .
Thank you for your time and effort. a sample code will be greatly
appreciated
cheers

My doubts are about whether entity beans can handle what I want to do. After I finished a successful project (not using EJB) which handled data-intensive lists with nested tags, I'm thinking of pursuing that design paradigm further. The value beans were created in the factories and passed into the action forms for use by the nested tags. The value beans had a validate() method, which took a Locale as the parameter when necessary, e.g. for date validation. Now I'm not sure if I can use the same principle in EJB. Can I take an CMP entity bean out of the J2EE container and use it in a struts form? And the reverse - can I pass a bean back again with updated values? You should not use EJBs in that way because the method calls are potentially very expensive.

Hi Sashi,
Don't know if you've received any replies to this, but I initially handled it the same
as you, but ran into problems when I was going back to the servlet for drop-down
actions etc. I only wanted validation errors to appear when the user hit the save
button, so I ended up just checking for the save in the validation method as such:
//only validate form when a save has been pressed
try {if (request.getParameter(saveBtn.x).equals(null)) return null;}
catch (NullPointerException ex) {return null;}
I'm also interested in feed-back on my approach.

/action

Betreff: Double log output from commons-logging with log4j
Hi folks,
I'm hunting for some time the cause, why I get double output lines from
log...
My LogonForm::execute looks similar to:
public ActionForward execute(
ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws Exception
{
System.out.println(LogonAction::execute called);
// Obtain username and password from web tier
LogonForm logonForm = (LogonForm) form;
String userid = logonForm.getUserid()
//
Log log = LogFactory.getLog(this.getClass());
if (log.isDebugEnabled())
{
log.debug(User +userid+ logged on);
}
// Return success
return (mapping.findForward(Constants.SUCCESS));
}
The output I get is:
...
[DEBUG] org.apache.struts.action.RequestProcessor - Creating new
Action instance
[DEBUG] org.apache.struts.action.RequestProcessor - Creating new
Action instance
LogonAction::execute called
[DEBUG] app.control.LogonAction - User A123456 logged on
[DEBUG] app.control.LogonAction - User A123456 logged on
...
Since I get LogonAction::execute called only once I'm pretty sure that
execute is only called once. I think it has probably to do with my
commons-logging.properties or log4j.properties, but I really can't spot
what I'm doing wrong:
commons-logging.properties:
org.apache.commons.logging.LogFactory=org.apache.commons.logging.impl.Log4jF
actory
log4j.properties:
# Logger catogory (DEBUG INFO WARN ERROR FATAL)

log4j.appender.Console.layout=org.apache.log4j.PatternLayout

Both are stored in the WEB-INF/classes directory.
Can anybody give me a hint?

You are assigning your console appender twice.
log4j.rootLogger=WARN,Console
log4j.logger.org.apache.struts.action.RequestProcessor=DEBUG,Console
log4j.logger.app=DEBUG,Console
log4j.logger.app will inherit the appender from rootLogger, so you can just
do
log4j.rootLogger=WARN,Console
log4j.logger.org.apache.struts.action.RequestProcessor=DEBUG,Console
log4j.logger.app=DEBUG

Betreff: Double log output from commons-logging with log4j
Hi folks,
I'm hunting for some time the cause, why I get double output lines from
log...
My LogonForm::execute looks similar to:
public ActionForward execute(
ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws Exception
{
System.out.println(LogonAction::execute called);
// Obtain username and password from web tier
LogonForm logonForm = (LogonForm) form;
String userid = logonForm.getUserid()
//
Log log = LogFactory.getLog(this.getClass());
if (log.isDebugEnabled())
{
log.debug(User +userid+ logged on);
}
// Return success
return (mapping.findForward(Constants.SUCCESS));
}
The output I get is:
...
[DEBUG] org.apache.struts.action.RequestProcessor - Creating new
Action instance
[DEBUG] org.apache.struts.action.RequestProcessor - Creating new
Action instance
LogonAction::execute called
[DEBUG] app.control.LogonAction - User A123456 logged on
[DEBUG] app.control.LogonAction - User A123456 logged on
...
Since I get LogonAction::execute called only once I'm pretty sure that
execute is only called once. I think it has probably to do with my
commons-logging.properties or log4j.properties, but I really can't spot
what I'm doing wrong:
commons-logging.properties:

Re: design issue MVC - forms, EJB, data marshalling
Adam Hardy wrote: I am starting a new app and trying to work out the best design approach. At the moment I want to get the app up and running, and so I'm just going to use tomcat and struts and achieve MVC by seperating out the database access into factory classes. At some point after I've got the project running, I want to replace the factory layer with CMP entity beans in JBoss (mostly for the learning experience). I've read Mastering EJB by Roman et al and so have a newby's idea of what the benefits would be although I'd like to hear what some gurus out there who've got experience with CMP say. My doubts are about whether entity beans can handle what I want to do. After I finished a successful project (not using EJB) which handled data-intensive lists with nested tags, I'm thinking of pursuing that design paradigm further. The value beans were created in the factories and passed into the action forms for use by the nested tags. The value beans had a validate() method, which took a Locale as the parameter when necessary, e.g. for date validation. Now I'm not sure if I can use the same principle in EJB. Can I take an CMP entity bean out of the J2EE container and use it in a struts form? And the reverse - can I pass a bean back again with updated values? I think it would be better to employ the session facade pattern, perhaps using a Session bean, for a couple reasons. 1) you don't expose the entity beans (essentially they are wrapped privately in the session facade) 2) you can populate some POJOs like value objects or whatever from the data in the entity beans Note that if you are using CMP (esp 2.0), you may find it faster to simply develop with CMP and skip the factory business (unless your factory classes really are just prototypes and you don't spend too much time perfecting and goldplating them) -- the whole point is that you don't have to do all the hand-coding when you use CMP. Use XDoclet to spare yourself the hassle of generating all the boilerplate, and some app servers (such as JBoss) have XDoclet tags that will generate the database for you. See xpetstore-ejb (http://xpetstore.sourceforge.net/) for an example of this. Erik - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Thanks for the response Rich. This did not work, but it did get me started
on the right path.
This code in the jsp:
html:select property=week value=%= request.getParameter('Week') %
results in this error:
myaddedit.java:213: unclosed character literal
probably occurred due to an error in /list/myAddEdit.jsp line 21:
html:select property=week value=%= request.getParameter('Week') %
The problem is that Java and JSP have different interpretations of quoting
literal characters (single and double quotes):
* In JSP, you can use either kind of quotes for an
attribute value, as long as they match.
* In Java, single quotes are used for character literals,
and double quotes are used for strings.
So, the following would do what you want:
html:select property=week value='%= request.getParameter(Week) %'
Note the use of single quotes around the attribute value for value, so
that you can use double quotes inside the Java expression.

The best you can do is throw away the ClassLoader that loaded that class (which is what containers like Tomcat do when you reload an existing app) . The fact that JSP pages can be recompiled only works because the container goes to EXTREME lengths to load the class for each page in a separate class loader -- but that doesn't work in the general case, because there is no way to know what other classes might refer to a particular class.

Whenever I changed anything in the application.properties or struts-config.xml, or any of my dtd's and .xml files(including validation.xml, which is such a pain...), I would have to recompile the project and restart tomcat. The only thing that doesn't require recompile is changes made to any .jsp files or .java files. Even with .java files, if there is synchronized(Object) statement, the debugger would give me a warning saying things 'may out of sync.'

I also used your method to check whether to validate, in situations

RE: Struts and database
What! You don't have to recompile when you make a change to your properties file? Compiling is only for Java code. Text files don't need to be compiled so you might be talking about rebuilding your app? David Man, I must've been doing something seriuosly wrong. Whenever I changed anything in the application.properties or struts-config.xml, or any of my dtd's and .xml files(including validation.xml, which is such a pain...), I would have to recompile the project and restart tomcat. The only thing that doesn't require recompile is changes made to any .jsp files or .java files. Even with .java files, if there is synchronized(Object) statement, the debugger would give me a warning saying things 'may out of sync.' I am using Eclipse 2.1, which btw is much better than visualAge 4.0:). I store all of my sql statements in a properties file and use ? for replacement parameters into PreparedStatement objects. That way I can support many databases by swapping in a different properties file. Even if you only need to support 1 database it's still useful because you don't need to recompile to change sql. There is a Mapper project in the commons-sandbox that supports this. I should also mention that Mapper also makes it trivially easy to pass in a collection of objects to fill the ? sql parameters. If you use Mapper, please send me feedback :-).

RE: ActionForm 'reset' method being called when JSP is rendered
If what your saying is true, it would break a *lot* of applications that create/reuse an ActionForm in a particular scope and then forward to a page.

My understanding is that 'reset' should not be called again until the form on the second JSP is submitted. Have I completely mis-understood how this works?

File size limit on uploads?
Chaps, I have been having a number of problems with multipart/form-data uploads of files, what I thought had been a problem with the sequence of events (see my previous posts) now seems to be a problem of the size of file being uploaded. I was convinced that at some point I had managed to upload a 70Mb file, I think it must have been wishful thinking on my part... :) The problem is as follows: 1. I GET a page that displays a form for uploading multiple files. 2. The user selects a file and POSTs the form using the submit button. 3. If the file seems to be = 2Mb(ish) the Action receives no form parameters or attributes excluding the usual suspects (instances of org.apache.struts.action.MESSAGE, org.apache.struts.action.mapping.instance and org.apache.struts.action.MODULE) 4. There appears to be no exception being thrown, certainly not on that is bubbling up into my code! 5. I do not have a maxFileSize set in web.xml Does anyone have any ideas?

First off you need to read the Java Blueprints on using DAO with J2ee. This will teach you the best methods of using Databases by using the DAO to encapsulate the DataSource . Here is the link to the Java Blueprints http://java.sun.com/blueprints/corej2eepatterns/Patterns/DataAccessObject.h tml read this complete document and it will help you out alot with how you should use your databases in your applications. Lets use an example say for a User requesting a item from the online store for our example. First you build the ActionForm which stores the data sent by the form. The ActionForm is passed through the FrontController which in turn dispatches you to the correct Action. In our case the Action will be using methods from a class which contains all of your Buisness logic. Form example, we have a ItemDAO which has a method getItem(int itemNum). This method returns a ItemBean which stores all of the information about that item. This Bean you are using to store all of the information is called a State Bean (if I remember right, corrections are welcome). When you get the ItemBean returned from the method getItem(int itemNum) you can then add it to your session/request etc.. for example you could do request.setAttribute(itemBean, itemBean). Now once you return the ActionForward in the Action (Example: mapping.findForward(success)) the itemBean will be part of the request and you acn access these properties in the View using jsp, velocity etc.. I hope this helps you out. --Sloan p.s. Sorry for the type o's I didn't proof read Hi! Would anyone give me some examples of database programming, which lead from retrieving data to rendering view.

This code will go get it and give you an InputStream to read from (there may be better ways -- I just hobbled this together): InputStream in = new StringBufferInputStream( new URLConnection(new URL(myXsl)).getResponseMessage() ); This is expensive, so if you need to get this often and it doesn't change much, you should cache it within your app. Be sure to consider what a reasonable cache strategy would be, though.
