I know WebSphere 6 came out with alot of support for that stuff, but I'm not sure about WebLogic.
One way to do it, but not rely on any one specific vendors implementation is to use the Google Web Toolkit APIs for dragging and dropping and embed them in a portlet. It's some pretty slick code, and not too difficult to master.
WebSphere Process Server introduced something like iGoogle, called Business Space.
Business Space it is like a portal engine but not so powerful. The portlets are named widgets. Also Google widgets can be installed on Business Space.
Anyway, looks like some useful stuffs is getting those who have to play with WebSphere Process Server. There are about 40-60 widgets designed and already implemented for Process Management and Monitoring.
With this addings users of WPS is getting a more usable process szerver environment. At least it helps software designers to use processes in a more natural fashion. Until now I couldn't seen an intelligently customised software solutions with processes. Maybe we get stuck in J2EE a little bit more than should be.
This is regarding the problem of drag and drop of portlets.
We have just migrated to WPS 6.0 from WPS 5.1 so with all our old customized themes and skins.
Now we wish to have the feature Drag and drop in our customized(migrated) themes and skins.
So far I have made the changes in Control.jsp of our skins and now portlets can be dragged, but we are unable to find out the way how to make them droppable? We are not getting where to define drop targets whether in themes or skins?
I have also copied UnlayeredContainer-H.jsp and UnlayeredContainer-V.jsp of IBM skin and pasted them inside my skin folder. But of no use
