RE: PropertyUtils.copyProperties() usage in 1.1-b2
Craig, Rana,
thanks for your responses, hoping you guys can provide some input:
From: Craig R. McClanahan [mailto:[EMAIL PROTECTED]]
Subject: Re: PropertyUtils.copyProperties() usage in 1.1-b2
I'm trying to figure out what I am doing wrong with
PropertyUtils.copyProperties(). From within my Action, I have:
User user = bean;
DynaActionForm regForm = (DynaActionForm) form;
PropertyUtils.copyProperties(regForm, user);
When I look at what copyProperties is doing, it's getting a
PropertyDescriptor array from getPropertyDescriptors() with the user
bean correctly, then it iteratively tries to see if the
regForm has any
of the properties found in the user bean. But calling
getPropertyDescriptor(regForm, fieldname) seems to be
comparing the
(correct) field names from the bean against the *structure* of the
DynaActionForm component (i.e. the multipartRequestHandler,
dynaClass,
servlet, etc), instead of the DynaFields that I set up in my
form-bean/.
Which CVS version number of PropertyUtils are you looking at
(second line
of the sources? The version I'm looking at, 1.32 (i.e. the current
nightly builds), does not call getPropertyDescriptors() on a DynaBean.
K, here's what I'm seeing under PropertyUtils 1.32:
in copyProperties:
orig is neither Map nor DynaBean, so line 283 calls
getPropertyDescriptors(orig). Then, for each readMethod in the result, line
296 has:
String name = origDescriptors[i].getName();
if (getPropertyDescriptor(dest, name) != null) {
But getting into getPropertyDescriptor(), line 869 calls
getPropertyDescriptors(bean). If the dest is a DynaBean, I'm not seeing
where the instanceof DynaBean is -- it simply calls
Introspector.getBeanInfo().getPropertyDescriptors(), but the result of
getBeanInfo doesn't know anything about DynaBeans.
What am I missing here? Rana says this is working and appreciate his input,
especially with the release notes reference (thanks!) But tracing through
the code and triple-checking at the beans (they both have a name property),
I still can't see how this is going to work, and in practice, the destination
DynaBean is untouched.
Thanks again,
-b

ActionServlet unable to proceed...pl help
Hi!
While running the following code (more or less same as Javaranch's march article) in

blank page...seems ActionServlet is unable to proceed. Here's my directory structure

Wrong form bean instantiated by controller!
I have an index.jsp, which optionally %@ include %s two fragments: one is a login form (connected to a LoginForm action form bean), the other a list of items. The login form is only included if there is no user bean in the session scope (determined via logic:present tags). The other fragment is always included, but if the user is logged in, each item has a form associated with it. I have an action (FrontPageAction, frontPage.do) which puts an ArrayList of Foo objects in the request scope, then forwards to the index.jsp. Easier to explain with a code snippet... foos is a request scoped ArrayList of Foo objects (which has legLength and fooID properties): logic:iterate id=element name=foo pbean:write name=element property=legLength//p logic:present name=user scope=session html:form action=/rateFoo input type=hidden name=fooID value=%=((Foo)element).getFooID()%/ html:radio property=rating value=1/ html:radio property=rating value=2/ html:radio property=rating value=3/ html:submit value=Rate!/ /html:form /logic:present logic:iterate/ So, with nobody logged in, hitting frontPage.do displays the front page correctly. I get my list of Foo objects (with no rating forms) and my login form. I log in, and the last thing my LoginAction does is forward back to frontPage.do. The login box is no longer displayed, and the rating forms should be, but it breaks because the LoginForm bean is still there, instead of a RatingForm! So I get a stack trace, complaining that org.apache.struts.taglib.html.BEAN doesn't have a rating property. But if I then type frontPage.do into my address bar, everything works as expected! So my questions are: 1. Is this a good design? Am I allowed to have multiple different forms on the one page, or should I have a seperate guestIndex.jsp and memberIndex.jsp? 2. Am I allowed to have many of the *same* form on the one page, distinguishing which element is having its form submitted by looking at a hidden property? Or should I go about this differently, using javascript tricks (I'd prefer to avoid this if possible). 3. Should I need to remove anything from the request scope at the end of my LoginAction, and if so, what?

I answer to me: yes you can reference to a Struts action from a tile.

Having redirect=true in the forward of an action is quite good. But it is incompatible with tiles, which are also quite good. Tiles needs to use request attributes to communicate information between the tiles on a page. Using a redirect loses att request attributes, because it requires a round trip to the browser and back. -- Martin Cooper Is it a feature? This e-mail is intended only for the above addressee.

Normally, I would expect the tag to look like:
html-el:img src=${image.name} ... /
because it's conventional to have a taglib line like:
%@ taglib uri=/WEB-INF/struts-html-el.tld prefix=html-el %
However, if you used a prefix of html instead of html-el, then that could
work, although it would be unconventional.
The fact that your attribute value isn't getting translated means that you're
either using the wrong prefix, or you didn't specify the correct taglib line.

Re: Example of indexed properties and DynaBean?
Hi, I had a quick look at the beanutil code. I can't find any code wich instantiates an empty array of the required size (given by the form data in the request). I wonder whether that ever worked. IMHO you have to specify the array size with an inital value in the form config. But then you'll have a fixed size array :( My idea is to write a new kind of List implementation which extends itself in size when the set method is called. So the List will resize itself to the number of indexed form elements. Btw, does your exception gets thrown when you submit your form data or when you display the form the first time?

SEGMENTATION VIOLATION..
Hi, I have an application that is running on OC4J. We are using struts to implement the application.. One of the module searches for the records fetches the result from database. SInce the Database hits need to be minimised we are fetching around 100 records at a time we are storing them in session object. The records are collection of HashMap which are stored in ArrayList..that is to tell that the result is an ArrayList of HashMap.. Now after some time when the program tries to access request.getSession(false) Oc4J is throwing the following stack trace the server crashes abruptly.. I have attached the stack trace for teh refernce below.. Has anyone come across this problem before? Is there any limit on the size of the data that will be placed in the session I did search the web but I havent been able to find the information of the limit Except that IBM site has an article for their application server where they manage this overflow of session.. Please do give me some inputs on this..

RE: SEGMENTATION VIOLATION..
I'd say you have a bad install of Java on your OS, not a Struts problem. You should never see the VM crash under any circumstances where the VM and the OS are installed correctly. What OS are you running on? Are you running the most current updates of everything, including the OS? What threads type and versions are you using? You probably have an incompatibility somewhere between those three. It's impossible to for a company to test on every version combination possible of OS, threads version, and Java VM version, so your best bet is to use a version combination that others are using, (but unfortunately, I can't help you on that one ;) HTH, good luck, -b -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]

RE: Enabling Disabling
Hi , Again the problem here is we need to extract the Attribute and use the correct variable in JSP page. I am not sure is there any other option. What I would like to do is Suppose I have a text field NAME I will use a NAME_CTRL_FLG (Naming will be standardised) in my Bean. We have some complecated logic to decide whether this field should be enabled/disabled, and we will set the value of NAME_CTRL_FLG to true/false in action. So my requirement is just to reffer the Attribute name of the Bean in the Custom Tag and then enabling disabling should be handled by the Custom Tag. In this case binding is by naming standardization. Pls suggest if there is a better way /Is STRUTS doing something similar already?

[Struts Tip] #15 Use chained exceptions
Many Java mavens recommend that business objects throw their own exceptions. Internally, a component may catching a SQL or IO exception, but what we really need to tell the user is that a data access error occurred. Of course, at the same time, you do not want to sacrifice any detail from the original exception. Retaining detail from the exception can especially important in a layered, multi-tiered, or multi-platform application.. The business component may not have direct access to the log, and the exception is its only way of telling us what went wrong.

Re: Enabling Disabling

Chennamakal Hi ,
Chennamakal Again the problem here is we need to extract the Attribute and use the
Chennamakal correct variable in JSP page.
Chennamakal I am not sure is there any other option.
Chennamakal What I would like to do is
Chennamakal Suppose I have a text field NAME
Chennamakal I will use a NAME_CTRL_FLG (Naming will be standardised) in my Bean.
Chennamakal We have some complecated logic to decide whether this field should be
Chennamakal enabled/disabled, and we will set the value
Chennamakal of NAME_CTRL_FLG to true/false in action.
Chennamakal So my requirement is just to reffer the Attribute name of the Bean in
the
Chennamakal Custom Tag and then enabling disabling should be handled by the
Custom Tag.
Chennamakal In this case binding is by naming standardization.
Chennamakal Pls suggest if there is a better way /Is STRUTS doing something
similar
Chennamakal already?
This (untested) is how you you specify that a text field is disabled or not:
html:text name=formname property=textProperty
disabled=%= formname.getNameCtrlFlag() %/
Using Struts-EL, it would look like this:
html-el:text name=formname property=textProperty
disabled=${formname.nameCtrlFlag}/

Struts At ApacheCon 2002
If you're coming to Las Vegas this week for ApacheCon, there will be two sessions and a BOF specifically focused on Struts: * Session TU07 (Tuesday, 1:30-2:30) - What's New In Struts 1.1 * Session WE06 (Wednesday, 10:00-11:00) - Building Web Applications With Struts * BOF BOF03 (Tuesday, 8:00p-9:00p) - Struts After 1.1 -- Where Do We Go From Here? The BOF is primarily an opportunity to gather input from folks on our initial thinking about the 1.2 and 2.0 roadmaps, and to answer any general questions that people have. I look forward to meeting any Struts users (and developers) attending the conference. You can find me at one of these sessions, or hanging around the Sun booths in the Exhibit Hall.

dynamic img with EL
Hi,
We are using EL(JSTL) to display dynamic img tags.
html:img src=${image.name} width=730 height=350 border=0
usemap=#Map/
Is this valid ? It doesn't really pick up the value of the 'src' tag.
Having read the archives I've decided that there is no other way. We need
URL rewriting.
Thanks,

Question about object in struts form
Hello, I'm new to struts and have tried looking through the archives here as well as around the web and am unable to find the answer to my question. I'm guessing that it's not possible to do what I want, but figured I'd ask before giving up... So, I have a class User that contains a String for the name, and an Address object for the address (the Address object contains more Strings, etc for city, state, zip, address1, etc). I have defined all the get/set functions. I have a form that I want to use to edit the user info. No problem to edit the name. Problem is that I also want to edit the address fields. So, what I was hoping to be able to do was declare my dyna-form in struts-config to have a form-property with name=user and type=org.blah.blah.dao.User. Then in the jsp code I would refer to user.name, user.address.city, etc. I got this to work fine for creating and populating the edit page. The problem comes about when I try to save the changes. No matter what I try I get all kinds of errors in the BeanUtils populate. One that I can't seem to get around is that it seems to want me to have a hidden type for my user object, and when I do that it complains that it can't conver from type String to type User. The other weird thing is that in the logs it gives me the following: [Thread-4] DEBUG org.apache.struts.util.RequestUtils - -- DynaActionForm[dynaClass=userForm,user=org.taprootfoundation.trweb.dao.User@181497d] [Thread-4] DEBUG org.apache.struts.action.RequestProcessor - Storing ActionForm bean instance in scope 'session' under attribute key 'userForm' [Thread-4] DEBUG org.apache.struts.action.RequestProcessor - Populating bean properties from this request [Thread-4] DEBUG org.apache.commons.beanutils.BeanUtils - BeanUtils.populate(DynaActionForm[dynaClass=userForm,user=NULL] I don't understand why it has a value for user within the userForm, and then seems to lose it.

RE: ArrayList disappeared in ActionForm
Hi all!
Thanks to both for your reply. Sorry for my late reply (and my poor english)
but in the weekend I cant write to the group.
Here some code of my classes (comments are in spanish, sorry):
My ActionForm has:
public class FichaUsuarioActionForm extends ActionForm {
/** Datos del usuario */
private FichaUsuarioDataBean ficha;
/** Roles posibles para situar en el formulario */
private ArrayList rolesPosibles;
public FichaUsuarioActionForm() {
log.debug(Constructor iniciado);
ficha = new FichaUsuarioDataBean();
log.debug(Constructor finalizado);
}
public FichaUsuarioDataBean getUserDataBean() {
log.debug(getUserDataBean ejecutado);
return ficha;
}
public void setUserDataBean(FichaUsuarioDataBean user) {
log.debug(setLoginDataBean ejecutado);
ficha = user;
}
public ArrayList getRolesPosibles() {
log.debug(getRolesPosibles ejecutado);
return rolesPosibles;
}
public void setRolesPosibles(ArrayList _roles) {
log.debug(setRolesPosibles ejecutado);
rolesPosibles = _roles;
}
.
}
---
ficha is used to retrieve the values of a HTML form. rolesPosibles is an
ArrayList that I must use in the same HTML form (in a multicheck tag). They
are private, so I must set its values using the set function, and this
function writes to the log a message. The constructor writes to the log too.
In the Action before the HTML form, I use the setRolesPosibles() to put an
inicial ArrayList.
My HTML form is in the way (login/editarUsuario.jsp):
--
html:form action=/modificaUsuarioAction.do focus=userDataBean.user
enctype=multipart/form-data
html:text name=fichaUsuario property=userDataBean.user size=60 /
..
logic:iterate name=fichaUsuario property=rolesPosibles
id=elementoListadoRoles
html:multibox name=fichaUsuario property=userDataBean.rol
bean:write name=elementoListadoRoles property=string1/
/html:multibox
bean:write name=elementoListadoRoles property=string2 /br
/logic:iterate
So I use the rolesPosibles to put a list of checkbox in my HTML form. The
struts-config.xml is like:
---
form-bean name=fichaUsuario
type=es.mulria.bonsai.login.actionform.FichaUsuarioActionForm/
actionpath=/modificaUsuarioAction
type=es.mulria.bonsai.login.action.ModificarUsuariosAction
name=fichaUsuario
input=/login/editarUsuario.jsp
validate=true
/action
...
---
My problem is that if the validate() of the ActionForm has errors, and
returns to the HTML form, the ArrayList rolesPosibles has disappear (null),
but the ficha not, and has all the values the user puts in the HTML form.
The log is like (I only put the ActionForm log):
--
# The Action before the JSP creates the ActionForm with the ArrayList, and
puts it in the request

# All OK, the ArrayList continues in the ActionForm, and the JSP is
displayed.
# Now, I submit it. Struts takes the UserDataBean to put the values, the
problem is that now, the ArrayList doesnt exist (is null), Without calling
the constructor and without calling the setX (the log dont appear). How
can Struts change the ArrayList without calling any of that? Of course, the
others functions in the class dont use the ArrayList for nothing.

So, if the validate has some error and returns to the JSP, it has an error
when tries to retrieve the ArrayList of checkbox (null).
Some idea? Thanks for read all this (and sorry for my english)

Struts-el/JSTL/dynamic img
Hi,
I didn't make it clear. We are actually mixing JSTL and struts. Is that
disaster ?
Our tag
html:img src=${image.name} width=730 height=350 border=0
usemap=#Map/
generates
img src=${image.name} height=350 width=730 border=0
usemap=#Map
The html:img is inside a JSTL loop.We are not using struts-el.
Thanks,
Mohan
Did you load tld file correctly in web.xml and declare struts-el in your jsp
file?

Hi,
Eddie bush wrote. From the archives

... and if you happen to be able to use the JSTL ... David Karr wrote a
taglib for struts which should soon be in the contrib directory. It's
called
Struts-EL, and it incorporates the JSTL's EL engine into the standard
Struts
tags we all know and love. Using his taglib, you could do the following:
html:img src=${BEAN.property}/ Nice, eh? Search the archive for
struts-el, and you're bound to happen across how you can get the taglib.
If you're stuck using the HTML img src=... go with Martin's
suggestion.
My question is. Is this valid ?
html:img src=${BEAN.property}/
Though we are using JSTL, we are assuming it is the same as the Struts-el.
Same engine ?
Our tag
html:img src=${image.name} width=730 height=350 border=0
usemap=#Map/
generates
img src=${image.name} height=350 width=730 border=0
usemap=#Map
Do you see something wrong here ?
Thanks,
Mohan
