Re: [Springframework-developer] OGNL

[Pieter C. <pie...@on...>]

And if we combine your post with the one from Dion (defaults), we get:

// Default, may be left out:
<beans expr="string">
<value expr="string">

// Use this as the default for the whole xml file
<beans expr="ognl">

// Use this if you don't want to use ognl in this property
<value expr="string">
