RE: BeanUtils Date Converter
Of course, right after I sent the email, I figured out my problem. I
created the following class, then registered it in my ContextListener using
this line:
ConvertUtils.register(new SqlDateConverter(), java.sql.Date.class);
package com.caris.pmis.util;
import java.sql.Date;
import org.apache.commons.beanutils.Converter;
import org.apache.commons.beanutils.converters.*;
public class SqlDateConverter implements Converter
{
private org.apache.commons.beanutils.converters.SqlDateConverter
sqlDateConverter = new
org.apache.commons.beanutils.converters.SqlDateConverter();
public Object convert(Class type, Object value)
{
if(value == null || value.toString().length() 1)
return null;
return sqlDateConverter.convert(type, value);
}
}
Cheers,
Graham

Subject: BeanUtils Date Converter
Hey all,
I know this question has been addressed numerous times but I can't seem to
find the answer.
I'm trying to convert strings in my forms to java.sql.Date in my dto. Its
throwing a conversion error when my form value is null or blank. Is there a
way to get nulls or passed through the BeanUtils.copyProperties function? I
read that I may be able to create my own converters too. Is there any
documentation on this?
Cheers,
Graham

Re: BeanUtils Date Converter
Graham, I believe that you need to specify the null returned value: ConvertUtils.registerConverter(new SqlDateConverter(null), java.sql.Date.class); On 2004-Jan-19 15:01, Graham Lounder wrote: Hey all, I know this question has been addressed numerous times but I can't seem to find the answer.

RE: BeanUtils use in struts
Hi Craig, Thanx for your comments. It uses reflection on POJOs (plain old Java objects) but not on DynaBeans -- the implementation inside DynaActionForm is a HashMap with typesafe getters and setters. In my case I have a Custom DTO with setter/getters and a Form bean that extends DynaActionForm (with properties declared in struts config). However, BeanUtils.copyProperties() works for calling both BeanUtils.copyProperties(form,dto) and For BeanUtils.copyProperties(dto, form) ... Is it supposed to work like that, or is it weird that it's working in both Ways when I have a DynaActionForm? Thanx and regards marco - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Inside the PropertyUtils methods, it looks at the origin and destination beans individually, and uses reflection (or not) based on that. So, any combination of POJO and DynaBean works. In addition, your origin object can also be a Map (although currently the destination cannob be).

Hi,
We had teh same question.But I have read that the performance issue with reflection
has been resolved from jdk1.3 and jdk 1.4 so that it is almost undetectable.Check the

RE: BeanUtils use in struts
Reflection has gotten much, much faster than it use to be (JDK1.3 and JDK1.4
made a lot of improvements in speed).
Also consider that a lot of custom tags use reflection already (JSTL, Struts
tags). If you are using JSP, and custom tags than you are already using
reflection all over the place. Also consider that Struts using BeanUtils
internally to populate the ActionForm from the incomming request object.
In the general scheme of things the overhead of BeanUtils is dust on the
scale (for the usage you are talking about).
If you are really worried, use JUnitPerf and create a test that uses
BeanUtils and stress it.
I am sure there are much more effective ways to tune your web application
(like caching semi-dynamic pages and page fragments).

RE: BeanUtils use in struts
Reflection in 1.3 , 1.4 is much faster than it was in ancient java versions,
but is still slow compared to for example, using maps, etc.
In the case of a struts app for use with DTOs however, the difference is not
going to be of significance. In general, for most such applications it is
such things as access to the database that is the bottleneck, and also speed
on the network, etc... A difference of a couple of nanoseconds to populate a
DTO bean based on a user submission - or a dynabean from a bean for ui
display... I mean really - its quite irrelevant. Even if you have 5000 users
online simultaneously its probably not the bean population thats going to be
causing you problems...
Ive found it never works to try and think in terms of meaningless absolutes
like reflection is slow. It always depends on the context of your problem.
If you need to populate a million beans in a tight loop, reflection may not
be your best bet, but for populating a few dynabeans here and there ... the
performance difference is irrelevant. Abandoning reflection may get your
request processing time down from 1000 milliseconds to 999 milliseconds or
something like that... (I dont have the actual figures)
I personally have found that leveraging BeanUtils, has proven very
productive. It is very useful, and you wont regret the flexibility that
comes with it.
Heres a link to an older (2001) posting by Ted that itself contains quite a
few relevant links. Worth a read:

In my app,
Depends totally on what JVM you are using -- the answer changes with every
version. Whether it's visible to you (in terms of increased response time) is
even more variable, but in most web based environments the database is the
primary cause for delays, followed by network traffic. The only way that
reflection can make any difference at all is if you're CPU bound on your web
tier server.
I will gain flexibility (I don't need to write methods for
Populating dtos from form and vice versa), but am I going to lose much
In tems of performance?
Depends on your application environment (as described above), but it's pretty
unikely to cause a problem -- especially if you use dynabeans, which don't use
reflection at all :-).
Anyone can give his comments? I think BeanUtils is of great help,and it
would be a pity to give up the benefits that I get from it...
The only way to know if this matters in your application is to benchmark your
application. But there are thousands of Struts-based webapps in the world,
many using traditional ActionForms (and therefore heavily dependent on
reflection).
Aiming for fastest possible is the wrong target. Aiming for fast enough
lets you focus on other goals about your app (less code, easier maintenance,
and so on) also.

Well, I'd say maybe. Something like the following will work:
PropertyUtils.getProperty(map, key)
But this won't:
PropertyUtils.copyProperties(destMap, srcMap)
Nor will:
BeanUtils.populate(destMap, srcMap)
And if you do:
PropertyUtils.describe(map)
You get:
{class=null, empty=null}

Nah mate. Not using JSP. In this case Im actually traversing an xhtml DOM
and doing a getProperty() to get values when I encounter input elements

attribute. (or checked attribute or... whatever... for that type of field)
Id quite like the ability to have user defined forms (perhaps I could map
names to xpaths in an xml doc for persistance ... or whatever) where the
user needs merely to upload the xhtml for the form , and perhaps specify
which fields are required etc... and then my app would do the grunt work for

Subject: RE: beanutils populate problem with formbeans and vectors
Michael,
The problem is that the get method is being called when your Collection is
empty. This is causing the ArrayIndexOutOfBounds exception that you are
seeing. What I have done to prevent this problem is to code my getX(int
index) and set(int index, Object obj) methods like this:
public Object getMyVector(int index) {
if (index = myVector.size())
return ;
return myVector.get(index);
}
public void setMyVector(int index, Object value) {
int size=myVector.size();
if (index = size) {
for(int i=size; i=index; i++) {
myVector.add();
}
}
myVector.set(index,value);
}
For the get method, I just return an empty string if the index is bigger
than the current size of the vector. For the set method, I increase the size
of the vector up to the index if the current size is smaller, otherwise I
just set the value that the index points to. This alleviates the need to
pre-fill the Vector in the constructor.
This solution also works with indexed properties in an html form too.
Regards,
Richard

Subject: beanutils populate problem with formbeans and vectors
Hi,
I´ve always get an Exception, when I try to change my scope in the
struts-config.xml from session to request.
I think the problem is that I have a getter and setter for a vector in my
formbean.
Everything works well with the scope session. My formbean is also
working if i completly remove the getter/setter vector out of my bean and
my jsp´s.
But I´d like to use a bean in a scope session with a getter/setter for
vectors. Anybody has a clue about this problem. I read some things in the
mailarchive, but that didn´t help me.

Subject: BeanUtils getPropertyDescriptor error
Hi,
Having gone live with our webapp (and changed the logging) an error stated
to appear in our logs. However the app is functioning fine. Is this error
a
problem ? The error occurs with submitions from jsps which contain radio
buttons. In our action class we extract the request parameters to
establish
the state(s) of the radio buttons to process the request.
Is all this ok or am I missing something here ?
Is this happening during the population of the form bean (which Struts
does for you)? Do the exception messages show up only in the debug
messages, and not cause problems in your application itself?
If the answer to both questions is yes, then this is harmless. The
BeanUtils.populate() method operates like this:
- Iterate over the keys in the Map that is passed in (i.e. over
the names of all request parameters included in the request)
- If there is a matching property on the destination bean,
do the appropriate set
- If there is no matching property on the destination bean,
ignore this request parameter
The exception is being triggered by the getPropertyDescriptor() call used
to test the third condition.

Also ... would it be better to use PropertyUtils.copyProperties since the properties have exactly the same type? PropertyUtils.copyProperties() will be faster than BeanUtils.copyProperties() because it won't waste time trying to figure out what conversions are necessary. Therefore, you should use the PropertyUtils version when you can (i.e. when all the property types match). Sorry if that is very clear .. its my first time using this .. be gentle.

Re: BeanUtils
JavaBeans indexed properties (which BeanUtils uses under the covers) only support array based properties for indexed storage. BeanUtils was extended fairly recently to do better with Lists. If you have a particular test case that doesn't work, please post it as an attachment to a bug report against BeanUtils: http://nagoya.apache.org/bugzilla/ Craig On Mon, 26 Aug 2002, petra staub wrote: Date: Mon, 26 Aug 2002 11:59:47 +0200 From: petra staub [EMAIL PROTECTED] Reply-To: Struts Users Mailing List [EMAIL PROTECTED] To: [EMAIL PROTECTED] Subject: BeanUtils hi, I know this is a struts-maillist but as the beanutils are commonly used with struts (and I didnt get any feedback in the commons-user list) I dare to ask my question here. :) i recently came over the very useful classes of the BeanUtils package. however, i have some problems... for testing, i simply wanted to use the copyProperties method to populate the values of one object to an other (empty) object. i created a class with different properties (int, float, String, Hashtable, Vector) and the corresponding getters/ setters. everything worked fine (the values were copied :) ) except for the Vector which gave me an error: Error in PropertyUtils.copyProperties(): Property vecElem has no getter method however, I have a method public Vector getVecElem() and even (for other usage) public Object getVecElem(int idx). I also tried to used the ArrayList instead of a Vector what helps to get rid of the error message, however, the values are not copied. Are Lists not supported with the BeanUtils?

I'm also having trouble concerning indexed properties with BeanUtils. If
the type of the indexed property is String, then BeanUtils.populate throws
IllegalArgumentException.
Using your NameBean in an example:
...
NameBean nameBean = new NameBean();
BeanUtils.populate(nameBean,new String[] {John, Paul, Jack});
// above throws IllegalArgumentException!
...
If I take the same indexed property and change it to an int
BeanUtils.populate works!
I've posted this problem to both the jakarta-commons-dev and struts-user

Hi Oliver, I don't. If I have a value object in a form bean and I and only wish to alter a couple of its properties how can I do it.

RE: BeanUtils/RequestUtils Populate question
But on the other side, if you have set the request scope for you form, than the values are set in the preparing action, it is transformed to your jsp and the form on the jsp is filled. then the form object will be deleted cause it was only in the request. So if you submit your form then a new form object is created which will be filled with the entered values. So he is not able to transfer the data between the two form beans. You have to store the missing data manually for using it in the next request. -Original Message- From: Jon.Ridgway [mailto:[EMAIL PROTECTED]] Sent: Tuesday, April 02, 2002 5:08 PM To: 'Struts Users Mailing List' Subject: RE: BeanUtils/RequestUtils Populate question Hi Oliver, I don't.

RE: BeanUtils/RequestUtils Populate question
Hi Oliver, I see what you mean. Looks like a design floor on my part. I don't wish to put the forms in the session scope as I already have the ValueObjects there. I'll try using the PropertyUtils.copyProperties stuff to transfer back and forth. Thanks for the clarification Jon. -Original Message- From: Oliver Reflé [mailto:[EMAIL PROTECTED]] Sent: 02 April 2002 16:15 To: Struts Users Mailing List Subject: RE: BeanUtils/RequestUtils Populate question But on the other side, if you have set the request scope for you form, than the values are set in the preparing action, it is transformed to your jsp and the form on the jsp is filled. then the form object will be deleted cause it was only in the request.

RE: BeanUtils deprecated?
Sorry... just tired... from javadocs: At some point after Struts 1.0 final, will be replaced by an equivalent class in the Jakarta Commons Beanutils package. -Original Message- From: Paradis, André Sent: September 5, 2001 3:52 PM To: [EMAIL PROTECTED] Subject: BeanUtils deprecated? Hi guys, This has probably been answered before, BeanUtils is deprecated (struts 1.0). What is the correct alternative to this class? Thanks a lot, Andre Paradis
