Class TagLibConfiguration

java.lang.Object

org.mortbay.jetty.webapp.TagLibConfiguration

All Implemented Interfaces:

Serializable, Configuration

public class TagLibConfiguration
extends Object
implements Configuration

TagLibConfiguration. The class searches for TLD descriptors found in web.xml, in WEB-INF/*.tld files of the web app or *.tld files withing jars found in WEB-INF/lib of the webapp. Any listeners defined in these tld's are added to the context. The "org.mortbay.jetty.webapp.NoTLDJarPattern" context init parameter, if set, is used as a regular expression to match commonly known jar files known not to contain TLD files (and thus not needed to be scanned). <bile>Scanning for TLDs is total rubbish special case for JSPs! If there was a general use-case for web app frameworks to register listeners directly, then a generic mechanism could have been added to the servlet spec. Instead some special purpose JSP support is required that breaks all sorts of encapsualtion rules as the servlet container must go searching for and then parsing the descriptors for one particular framework. It only appears to be used by JSF. </bile>
