TldResourcePath (Apache Tomcat 8.5.53 API Documentation)

org.apache.tomcat.util.descriptor.tld

## 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.
