svn commit: r1337057 - in /ofbiz/trunk: framework/common/config/
framework/common/src/org/ofbiz/common/ framework/common/webcommon/WEB-INF/
specialpurpose/ecommerce/webapp/ecommerce/WEB-INF/
Author: lektran
Date: Fri May 11 08:23:02 2012
New Revision: 1337057
URL: http://svn.apache.org/viewvc?rev=1337057&view=rev
Log:
Copied the captcha image generator into a single event that streams the image to the response for a direct request rather than trying to store it during screen rendering to be served up later.
Added:
ofbiz/trunk/framework/common/config/captcha.properties (with props)
Modified:
ofbiz/trunk/framework/common/src/org/ofbiz/common/CommonEvents.java

+# You can then pass the sizename as a parameter to the captcha image generator using the parameter "captchaSize"
+# e.g. https://localhost:8443/ecommerce/control/getCaptchaImage?captchaSize=default
+captcha.default=22|40|149
