svn commit: r783060 - in /ofbiz/trunk/framework: base/config/ base/lib/ minilang/src/org/ofbiz/minilang/ webslinger/lib/

[doogie-3]

Author: doogie
Date: Tue Jun  9 16:19:50 2009
New Revision: 783060

URL: http://svn.apache.org/viewvc?rev=783060&view=rev
Log:
Add ability for simple methods to be wrapped with a custom compiled
class.  The resource location from where the simple method was read
is encoded as the classname of the proxy.  This makes debugging
simpler to do.  This feature is turned off by default.

The wrapping code has support for setting the line number, to include
in stack traces.  However, DOM-based xml parsing doesn't record line
numbers, so it's not possible to encode that into the wrapped proxy
class.
