Tag Library
The Calyxo Base custom tag library contains tags to link or send a form to an action. In a JSP file, just associate the prefix you want to use for the tags with URI http://calyxo.odysseus.de/jsp/base:
<jsp:root xmlns:jsp="http://java.sun.com/JSP/Page" version="2.0" xmlns:base="http://calyxo.odysseus.de/jsp/base"> ... </jsp:root>
Since the tag library descriptor is contained in the Calyxo Base jar file, it is already available to applications. The container will automatically find it. For documentation purposes, a copy is located in CALYXO_HOME/calyxo-base/conf/share/calyxo-base.tld.
All attributes may be expressed using runtime expressions. Most of the attributes are optional. If an attribute is required for a specific tag, this is mentioned in the corresponding attribute description (and indicated by an attribute name printed in bold).
