JSP Controls Tag Library - http://jspcontrols.sourceforge.net/
Supports the lifecycle and provides the template for portlet-like JSP components. The Library does not require a portal engine or other central controller. The components built with the Library use Struts actions to process input data and to change component state.

• Supports dual-mode components (non-Ajax and Ajax) therefore works even with Netscape 4.
• In non-Ajax mode components utilize synchronous HTTP request/response cycle via Redirect-After-Post pattern.
• In Ajax mode components are updated in-place.
• Component reload in non-Ajax mode is completely automatic and transparent.
• Transition between Ajax and non-Ajax mode is undetectable when Javascript being switched on and off.
• Apache 2.0 licence.
• Live demo
