Unfortunately, it is not currently possible to vote for this app in our wishlist. We are currently focused on providing new PHP, Rails, Java and Python apps.
Jetspeed is an Open Portal Platform and Enterprise Information Portal, written entirely in open source under the Apache license in Java and XML and based on open standards. All access to the portal is managed through a robust portal security policy. Within a Jetspeed portal, individual portlets can be aggregated to create a page. Each portlet is an independent application with Jetspeed acting as the central hub making information from multiple sources available in an easy to use manner.
