Not sure. The final manuscript went out last week.
This is my first book with a real publisher, no idea how long it takes
to go from manuscript --> printed book on the shelf at your local
bookstore. Will let you know, they usually become available at Amazon a
few weeks early.

i put the code here:

Lets see how we can refactor it and possibly prepare it for committing
to graffito

Should have a demo available online soon....

Its a JSP taglib. Of course it would be possible.
I often get requests to port the Browser (DatabaseBrowser) in Jetspeed
and Jetspeed-2 from Velocity to JSP. This is the first in the other

When I get the demo online you can see it in action.

I agree

provides a very large process action method.  That's why I'm refactoring to code to use some
PortletActions. I will introduce this small feature next week and If needed send the code
to the J2 team (not yet commited).
Take a look at the Bridges Framework project under the Jetpeed-2 cvs.
It already has portlet actions features.
Lets try to find a common ground on these efforts

the code to the J2 team when it will be used in the Graffito portlets.

We should create a status page on our website so that we can update our
status instead of tracking it on email
