I'd like to customize the jsp parts files… I've read the documentation for customizing the web client and for Packageing and Deploying Extensions, but am still a little confused.
If I want to make a change to the titlebar.jsp part, do I have to reintegrate it with the alfresco war or can I put it in <jboss home>/server/default/deploy/conf/jsp/extensions or something like that?
Unfortunately, that's one of the few JSP files we do not have an extenstion mechanism for.
This file is included directly on each page throughout the application so to change the URL would involve changing every JSP page. You're best option therefore is to replace our titlebar.jsp with your version. Just remember to keep a copy for wen you upgrade.
