RE: [Springframework-developer] FW: [expertj2ee_with_rodjohnson] interface21 Properties editor in BeanWrapperImpl

[<jue...@we...>]

Hi Bruno,

The line registering PropertiesEditor isn't necessary because the same =
static initializer code that you cited contains the following:

	// Register all editors in our standard package
	PropertyEditorManager.setEditorSearchPath(new String[] {
		"sun.beans.editors",
		"com.interface21.beans.propertyeditors"
	});

All editors named XXXEditor in these packages get registered as editors =
for XXX automatically, like PropertiesEditor for Properties. The naming =
convention cannot be applied to String arrays, thus the explicit =
StringArrayPropertyEditor registration.

I don't understand why uncommenting the line made a difference in your =
situation. I use the web stuff a lot, and setting UrlHandlerMapping =
properties works nicely for me, without explicit PropertiesEditor =
registration. Hmmm, maybe a classloader issue?

Anyway, let me invite you to join one of our mailing lists. The project =
is now hosted at SourceForge and is called "Spring Framework":

	http://sourceforge.net/projects/springframework

You could try to download a current version of the framework and recheck =
the property editor issue for your application. Unfortunately, our first =
official release 0.8 isn't out yet, so you'll need to get the stuff from =
the SourceForge CVS. FYI, 0.8 should get released in April, and 1.0 =
around end of May.

Note that the i21-web-demo accompanying the book will probably not work =
on a current Spring version without slight modifications. There have =
been major new framework features since the book version, introducing =
some incompatibilities for the sake of clearness (like new subpackages, =
renamed classes and methods, etc). AFAIK, Rod has already tried to adapt =
the demo, but it isn't in CVS yet.

Regards,
Juergen

BeanWrapperImpl


Hi all,


When I deployed the i21-web-demo.war I had always an=20
ErrorCodedPropertyVetoException: errorCode=3D[typeMismatch]; =
message=3D(Failed
to=20
convert property value of type [java.lang.String] to required type=20
[java.util.Properties]

Anyway, I didn't have time to get to see what was happening, so I =
decided to

make a little demo using interface21 with a piece of webapp that I want =
to=20
migrate from struts to interface21. I've had the same exception.

After getting source with CVS and few moments in the code, I've been =
able to

see that in init of BeanWrapperImpl the line 57 :

PropertyEditorManager.registerEditor(Properties.class,PropertiesEditor.cl=
ass
);

was commented out. As the PropertiesEditor is necessary for listing of =
url=20
with the UrlHandlerMapping, I've removed the comment. After registering=20
PropertiesEditor, all worked well (the web-demo and my demo).

So why it was commented out ? Did I missed something (with for example=20
StringArrayPropertyEditor) ?

Is anybody having a clue about this ?=20
Thanks by advance.

Bruno THOMAS

PS : sorry for my poor english
