Class TldResourcePath

java.lang.Object
org.apache.tomcat.util.descriptor.tld.TldResourcePath
public class TldResourcePath extends Object
A TLD Resource Path as defined in JSP 7.3.2.

This encapsulates references to Tag Library Descriptors that can be located in different places:

  • As resources within an application
  • As entries in JAR files included in the application
  • As resources provided by the container
When configuring a mapping from a well-known URI to a TLD, a user is allowed to specify just the name of a JAR file that implicitly contains a TLD in META-INF/taglib.tld. Such a mapping must be explicitly converted to a URL and entryName when using this implementation.
