Standard Portlet Architecture Supports Reusable Components
OGCE2 is building Grid portlets that can operate in open source containers such as uPortal and GridSphere.
JSR 168 standard allows portlets to be reused across multiple containers.
The Java CoG provides an abstraction layer over different toolkits and capabilities.

MyProxy and GRAM portlets in uPortal and GridSphere
New CoG interfaces also support task composition and workflow
Container independent services allow data like Grid credentials to be shared between portlets.
Compatibility tools support Velocity-based OGCE1 portlets in JSR 168 containers
