Open Source Template Engines in Java

IKAT is the templating engine for RSF, an open source Web programming framework based on Spring. The IKAT engine is standalone and can be used without the rest of RSF. IKAT is unique in being the first \"completely pure\" HTML templating engine. Unlike others, it not only permits *no* logical constructs (tests, branches, iterations etc.) to be expressed in the template, it allows no \"model\" references in the template and further it adds no tags to its target language - just one single attribute, the rsf:id. Replication and branching, instead, is \"induced\" in the template structure by a unique \"structural matching\" algorithm based on a tree of lightweight \"components\" produced by the user.
