Hi All,
Has anybody worked with Shale on Websphere Portal 5.1 and
RAD.?????
I am not getting any refernece on the net.
If yes then please help me to get shale up and running on
Websphere.
I am getting the exception : "Exception during portlet
initialization".
Adrian in the mean time i am trying to use shale-core.jar
source code for token.
a) component-Token
b) renderer-TokenRenderer
c) taglib-TokenTag
d) utils-TokenProcessor
e) META-INF-taglib.tld and facesConfig.xml.
phew... have i missed anything.(its like re-inventing the
wheel)
Best Regards,
Pallavi

You could just download the token's source code and use only the
component without the other features of shale-core

Hi All,
I had posted a similar query earlier to prevent double click of
a form button.
I could use Shale's <s:token> but i ran into compatibility
issues between RAD6.0.1 and Shale-core.jar1.0.3.
So i had to give it up and try another approach using
Synchronizer Token pattern as in sytuts.
Please help me fine tune it.Please go ahead to provide me any
other elegant approach.
I want to call the method generateSaveToken() from
phaseListener.
Is it possible.????
