Re: Problems with an inherited getter in a derived bean

[Gareth Andrew]

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
Gareth.

PS.  I've also appended a quick test app I wrote

--scratchpad.java --

public class scratchpad {

   public static void main(String[] args) throws Exception{
   publicNestedClass test = new publicNestedClass();
  
   //Works - nested inheritance works ok
   //System.out.println(test.getMessage());
  
  
   //Doesn't work PropertyUtils bug
   //System.out.println((String)PropertyUtils.getProperty(test, 
"message"));
  
   Class c = publicNestedClass.class;
   Method m = c.getMethod("getMessage", null);
   if(m!=null){
   System.out.println("Method " + m.getName() + " of " + 
m.getDeclaringClass() + " found.");
   System.out.println("Method " + 
(Modifier.isPublic(m.getModifiers()) ? "is" : "isn't") + " public");
   System.out.println("Class " + 
(Modifier.isPublic(m.getClass().getModifiers()) ? "is" : "isn't") + " 
public");
   System.out.println("Declaring Class " + 
(Modifier.isPublic(m.getDeclaringClass().getModifiers()) ? "is" : 
"isn't") + " public");
   }
  
   System.out.println((String)m.invoke(test, null));
   }
  
   protected static class protectedNestedClass {
   public String getMessage(){
   return "Hello from a protected nested class";
   }
   }
  
   public static class publicNestedClass extends protectedNestedClass{
  
   }
}

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  
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



- 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

You can query bugzilla for a list of current bugs and enhancements.  
I'm basically working alone on validator right now but Rob Leland has 
recently moved the Javascript stuff from Struts over to commons and 
added a UrlValidator.

Here are some things I'm planning for commons-validator 2.0:
- Move base Java requirement to 1.4.  I tested replacing all of the 
ORO classes with the Java 1.4 regex equivalents and there was a 50% 
speed increase.
Does that mean that future struts-1.x releases will be unable to use 
commons-validator 2.x without changing the Struts base requirements to 1.4?

Gareth.

- Change "form" and "field" semantics to "bean" and "property" to 
better align the validator with bean validation as opposed to form 
validation.  Forms are just a special case of bean validation.

I'm comfortable enough with the current changes to cut a 
commons-validator-1.1 release after Struts 1.1 goes final.  All help 
and contributions are welcome!

Re: DateUtilities for ActionForms?

[Gareth Andrew]

java.util.Date exists simply to *store* dates, the calendar class and 
the dateFormat class exist to *manipulate* dates.  java.sql.Date exists 
because SQL has different conventions for storing a date than the JVM.
The Java API docs for java.util.Date explain the deprecated methods.

"Prior to JDK 1.1, the class |Date| had two additional functions. It 
allowed the interpretation of dates as year, month, day, hour, minute, 
and second values. It also allowed the formatting and parsing of date 
strings. Unfortunately, the API for these functions was not amenable to 
internationalization. As of JDK 1.1, the |Calendar| class should be used 
to convert between dates and time fields and the |DateFormat| class 
should be used to format and parse date strings. The corresponding 
methods in |Date| are deprecated."

java.sql.Date is simply a java.util.Date object that has its hours, 
minutes, and seconds values set to zero since SQL DATEs do not have a 
time component.

In summary,

java.util.Date is the standard java API mechanism for storing a date.
java.sql.Date is a subclass of java.util.Date with a subset of the 
functionality designed to represent the functionality provided by a SQL 
DATE.
java.sql.Timestamp is a composite of Date and an extra nanoseccond value 
designed to represent the functionality provided by a SQL TIMESTAMP.

p. 654: "Since Java 1.1 many of the methods in the Date class have been
deprecated in favor of the methods of the Calendar class."  java.sql.Date
exists simply to pass milliseconds through JDBC to and from a database.

Re: DateUtilities for ActionForms?

[Gareth Andrew]

What are you talking about?  I assume you mean the java.util.Date 
class.  This class is anything but deprecated, it is the de facto method 
of storing a date in Java. The reason it has a lot of deprecated methods 
and constructors is that in 1.2 the class was extensively refactored 
with a lot of the functionality moved into helper classes such as 
Calender and DateFormat.  I hope this isn't why you are recommending 
java.sql.date over java.util.date.

If you want to use Locale aware conversions perhaps you should be using 
LocaleBeanUtils rather than BeanUtils.  You should be able to convert a 
string to a date as follows:

java.util.Date myDate = (java.util.Date)LocaleConvertUtils.convert("18 
Jan 2003", Class.forName("java.util.Date"));

If you change your form-properties to strings, copyProperties() should 
automagically do the String->Date conversion for you - although I think 
it uses toString() for Date->String so you'd need to use the DateFormat 
class and some locale information you have about the user 
(request.getLocale()?) to reformat the string.

Have you tried using the BeanUtils converters. From the docs:

*org.apache.commons.beanutils.locale.converters.DateLocaleConverter

Standard |LocaleConverter| <cid:[EMAIL PROTECTED]>
implementation that converts an incoming locale-sensitive String into

It sounds like it might help, but I haven't used it before so i can't

Re: The Action, the bean and the JSP

[Gareth Andrew]

Torsten Schlabach wrote:

Dear List,

I am working with Struts for some weeks now, but there are just some
concepts that don't become clear to me neither from the docs nor from all that
tutorials. They all stop where my questions start. So first of all, I would like
to ask the list for confirmation on what I found out / understood so far.
Is it right that in a web browser environment:
a) everyhting starts with a request coming in
b) and the result of that is some web page beeing rendered in the browser
c) all that Struts (and other methodologies for application login in such an
environment) are about taking the input from the request to somehow generate
the output being sent to the browser
d) The request - response thing is stateless meaning that while processing a
request neither myself nor the framework should care about the preceeding or
potential following requests (with the little exception of *optionally*
keeing a session state in some session content)
Working from that assumption, I exlained to myself that this is what happens
inside Struts when a request comes in:
- The ActionServlet determines the appropriate action from the
struts-config.xml.
- In case that action has a form bean associated with it, it instantiates
that form bean and fills it with the request parameters.
- After that it calls the execute method on the Action passing the (now
filled) form bean instance in as a parameter.
- The code in the execute method can read information from the FormBean, do
calculations, lookups, whatever and write results back into the form bean.
- The execute method returns control to the ActionServlet letting it know
which JSP page to render (choosing either from local or global forwards).
- The JSP page is rendered using the FormBean (still the same one?!?) as a
data source and sent back to the broser?
Am I right or wrong until here?
 

Sounds fairly correct.

In case I am right (and in case I am wrong, too), please help me understand:

- Why do I need to use a *forward* to display the output page? (My
understand of forward would be: I am being sent somewhere else than I originally
intended to go.) It would be much more logical to me if my  in
stuts-config.xml had a "output" attribute (similar to the "input" attribute) that names
the page that I want to use to render the results of the action.
 

Your definition of forward is closer to the definition of "redirect".  
Forwarding is just transferring control (usually to a JSP page to render 
the view).
The reason its possible to to forward to more than one location, rather 
than just a single "output" attribute is that the action may have 
different outputs depending on some logic (for example I have a search 
action which returns one of three forwards depending on whether 0,1 or 
multiple items are found).

- If the results page contains a form that has an action associated to it
that the user *might* fire by clicking "submit" on the rendered page (he or she
could as well use a link to go somewhere else) Struts will instantiate the
form bean for that potential request already before even rendering the page
containing the form that will enable the user to make that request later (or
leave it). What's the sense in here?
 

There are generally two actions involved in handling user input with forms.

Step 1.  The user follows a link to a page with a form - for example, 
Edit user details.

Request --> Action1 --> EditUserForm.jsp

Step 2.  The user hits the submit button after filling in the form.

Request --> Action2 --> confirmation.jsp

Both actions will be associated with same form  in the struts-config.xml 
- lets call it newUserForm.
Before calling Action1.execute() Struts will instantiate a new 
newUserForm and call execute. The action may then wish to preopulate 
this form with some data from the model ie. from the database.  In this 
case it will be the users current details.  The action then forwards to 
the EditUserForm.jsp via a local forward (if errors occurred when 
loading the user data or some flag was set or something then perhaps the 
action might forward to a different location :-).  The jsp can then 
render the filled in values as HTML form controls.
The Action form instantiated for Action2 will be populated with the 
values that were filled in by the user.  Action2 can then submit these 
to the database.

I am sure I got at least one concept wrong. Please enlighten me.

Torsten

 

Hope this helps (sorry if i spelled things out a bit slowly)

Re: Loosing Objects in the Request.

Don't know if it will help but here it is:

<%@ taglib uri="/WEB-INF/struts-bean.tld" prefix="bean" %>

Method

PathInfo

PathTranslated

RequestedSessionId

RequestURI

RequestURL


ServletPath

Re: Where to catch/throw Exceptions in Struts Tiered Architecture

IMO, catch the database exception in user, then throw a new (wrapped) 
exception, catch it in UserAction and throw a new exception, and use 
struts decalritive exception handling features to handle it.  This 
avoids undue coupling between UserAction, User and Database.

Re: No action instance for path could be created

[Gareth Andrew]

Max, I'm curious as to whats wrong with using mixed case (camelCase) 
package names.  Obviously its better to remove any redundant words from 
package (or class, or object) names, but surely the advising someone to 
avoid mixed case package names is a little over prescriptive.

Gareth.

Your Action's fully qualified class name is src.ginsu.strutsApp.AddFileForm
but Struts will be looking for ginsu.strutsApp.AddFileAction.
I recommend removing src. from your package structure as it is probably a
mistake for it to be there. Many project directory structures have a 'src'
directory, but that should not be a part of the package name itself. Also,
avoid the use of mixed case package names, like 'strutsApp'. Simply using
'struts' or 'web' or something might be better.

Could it be that your action class is in package:

where my problem resides.  So I thought it best to
consult you more experienced struts users.  My first
guess is that I have configured struts-config.xml
incorrectly.
I will first list my struts-config.xml file (which is
where I _think_ my error may be), my addFile.jsp (a
simple form), my AddFileForm (struts FormBean), and my
AddFileAction class (Struts Action). 

I hope you guys can see something obvious.  Here's
hoping.
* struts-config.xml ***



 "-//Apache Software Foundation//DTD Struts
Configuration 1.0//EN"

"http://jakarta.apache.org/struts/dtds/struts-config_1_0.dtd";>



 
 
 

type="ginsu.strutsApp.ContentForm" />

type="ginsu.strutsApp.AddFileForm" />

 
 
 

 
   
   
 
 
 

   
  name="contentForm"> 
   
   
   
  name="addFileForm"
  input="/test/addFile.jsp">

*** end struts-config.xml ***

And now my jsp form:

*** Begin addFile.jsp ***



 Add an XML File to Slide







 
   
 Filename:
   
   
 
   
 
 
   
 

 
   
 
   
   
 
   
 






** End addFile.jsp 

My FormBean:

** Begin AddFileForm.java *

   }
   
   public void setFilename(String filename) {
   this.filename = filename;
   }
   
}

** End AddFileForm.java 

And finally, My AddFileAction class:

** Begin AddFileAction.java

  String fullPath = addForm.getFilename();
  StringTokenizer tokenizer = new

  Vector temp = new Vector();
  
  while (tokenizer.hasMoreTokens()) {
   temp.addElement(tokenizer.nextToken());
  }
  String slideFileName =

  String slideUri = "/files/" + slideFileName;

  } catch (Exception e) {

  }
  return mapping.findForward("xslServlet");
   }
   
}

Re: HELP: Dispaly Date in a JSP that used Tiles

It's about now I have to admit that my Javascript/DHTML knowledge is 
about 4 years out of date.  I have no idea how many browsers that this 
will work on, but it does seem to work on IE6.0 and Mozilla 1.3:

In your script replace:

document.myForm.dateControl.value=time;

with

document.getElementById("dateControl2").innerHTML=time;

and in your html/jsp replace :

   

with



Good luck,

Re: messages into struts 1.1

[Gareth Andrew]

I've just had a similar problem, recently. The docs seem to be a bit 
misleading (or perhaps the docs are right and theres a bug somewhere?).
 doesn't seem to do any actual writing, its just a form 
of iterator that loops through the specified messages and puts them in a 
page-scope attribute. To actually display them you need to use 
eg.




Note you may also need to set the message paramater of the html:message 
tag to "true" if you have created your messages using the 
ActionMessages.GLOBAL_MESSAGE key as the tag (confusingly) defaults to 
using ActionErrors.GLOBAL_ERROR

Hope this helps,

Gareth

Hi everyone,

Is anybody knows how to use messages system of struts. I just 
want to print some information on the user screen, so I use an 
ActionMessages object, then i fill it with ActionMessage, I 
save it, and in my jsp, I use the tag  in which messages is the name of my svaed 
object, but nothing is printed out? So perhaps I do not use 
correctly this?

Cheers

Re: HELP: Dispaly Date in a JSP that used Tiles

[Gareth Andrew]

Yup, the error is coming from

  

as it is looking for a FormBean called MyForm.
Instead use:

thank you for your answer but when you say "just use plain html tags"
it is what I do with   isn't it ?
But it doesn't work because when I run my application I have the error
"javax.servlet.ServletException: Cannot find bean myForm in any scope".
Why ?
With the plain html tag form, who is responsible for creation of the
form instance ?

You don't need to create an ActionForm, since the form is never going to 
be submitted, and you don't need to be able to access the form 
information outside of the current page. So just use plain html tags 
instead of the struts-html tags.

I think indeed that this manner of making is better

Because I must define a tag form. 

  


As I explained in my previous message I use Tiles all the
pages are composed of several modules header, menu, body and footer.
It is in the header module that I want to display the date,
for the moment the header.jsp page is the following:
<%@ taglib uri="/WEB-INF/tld/struts-bean.tld" prefix="bean" %>
<%@ taglib uri="/WEB-INF/tld/struts-html.tld" prefix="html" %>



  

  
  
 
   
  




When I run the application I have an error no instance of MyForm
has been created.
I thus defined a DynaValidatorForm in struts-config.xml,and use the Struts
tag
. But when I compile the application I have the
following
message "action is mandatory for tag form".
But I don't want to associate an action to this page.
How can I do ?

I think your problem has nothing to do with tiles or jsp.  You just need 
to write the output to a control instead of trying to write to the page.
If the browser were to allow your code to work as you have written it 
you would actually get a list of times.
The following code should work - it renders to a named textBox.

BEGINNING OF CODE SAMPLE --

<br>
 function aff_heure() {<br>
  var d=new Date()<br>
  var weekdays=new 
Array("Sunday","Monday","Tuesday","Wednesday","Thursday","Friday","Saturday<br>

PS.  You can also render to put your answer in other html objects such 
as spans and divs but if you're trying to make it work on as many 
browsers as possible that might be a bit of a headache.
PPS.  Why not use d.toGMTString() or d.toLocaleString() instead of 
trying to format the string yourself?
