As you know, JBoss Wiki is now in alpha stage, soon to become beta. Problem is it has some "hard links" to JBoss Portal classes now so moving to another JSR-168 container could be tricky at the moment.
I advice waiting for the final 1.0 release, so porting to other Portal would be a matter of writing few interfaces to integrate wiki with other portal's authorization etc.
If you'd be interested please let me know so i can work with You on the Grid Sphere integration of JBoss Wiki, once final version is released.
As a matter of fact i did some changes in the code so deploying in other-then-jboss-portal should be quite easy now. If you are interested please let me know - here, at email@example.com or AIM me at szimano
Any news on this subject?
Has anyone tried to implement the wiki portlet in a BEA Weblogic portal?
