PropertyPlaceholderConfigurer - Help

[parkerlouis]

Hello,

I am looking at using the Spring.Objects.Factory.Config.PropertyPlaceholderC onfigurer to be fined through a couple custom 'config sections' using name-value properties. Sounds easy enough... I have banged my head off the keyboard a few times and I am now turning to the support forum for some help...

The exception is being thrown when loading the System.Configuration.NameValueSectionHandler.

I have seen a couple forums with this exception and their work around is using Strong type naming for the System.Configuration.NameValueSectionHandler, System.Web, ... but there must be a easier way.

Thanks for your help,

Hi,

I don't know of another workaround - though it just seems like a minor pain. The property replacement works fine as far as I can tell in reproducing your setup. I did notice that

<value>${profile.connection.string}</value>
should probably be
<value>${toolkit.connection.string}</value>

Also, just curious, what are you doing in your own custom context?
<context type="Toolkit.Web.Spring.ApplicationContext, Toolkit.Web">

Are you inheriting from Spring.Context.Support.WebApplicationContext?

Cheers,
Mark
