How does RSP-UI relate to Tiles and SiteMesh?
Apache Tiles (Standalone) allows UI composition of modules via XML templates, while OpenSymphony SiteMesh is strong in combining and decorating arbitrary HTML streams. Both functionalities are very useful in the context of all types of web applications. Therefore, RSP-UI will build on their composition concepts for Eclipse/OSGi-based web applications. Project committer Cedric Dumoulin is the original creator of Tiles.
