Constructor Detail

• TldScanner

  public TldScanner()

  Default Constructor. This is only used for implementing ServletContainerInitializer. ServletContext will be supplied in the method onStartUp;

• TldScanner

  public TldScanner(ServletContext ctxt,
                    boolean isValidationEnabled)

  Constructor used in Jasper

Method Detail

• onStartup

  public void onStartup(java.util.Set<java.lang.Class<?>> c,
                        ServletContext ctxt)
                 throws ServletException

  Description copied from interface: ServletContainerInitializer
  Notifies this ServletContainerInitializer of the startup of the application represented by the given ServletContext.

  If this ServletContainerInitializer is bundled in a JAR file inside the WEB-INF/lib directory of an application, its onStartup method will be invoked only once during the startup of the bundling application. If this ServletContainerInitializer is bundled inside a JAR file outside of any WEB-INF/lib directory, but still discoverable as described above, its onStartup method will be invoked every time an application is started.

  Specified by:

  onStartup in interface ServletContainerInitializer

  Parameters:

  c - the Set of application classes that extend, implement, or have been annotated with the class types specified by the HandlesTypes annotation, or null if there are no matches, or this ServletContainerInitializer has not been annotated with HandlesTypes

  ctxt - the ServletContext of the web application that is being started and in which the classes contained in c were found

  Throws:

  ServletException - if an error has occurred

• getLocation

  public java.lang.String[] getLocation(java.lang.String uri)
                                 throws JasperException

  Gets the 'location' of the TLD associated with the given taglib 'uri'. Returns null if the uri is not associated with any tag library 'exposed' in the web application. A tag library is 'exposed' either explicitly in web.xml or implicitly via the uri tag in the TLD of a taglib deployed in a jar file (WEB-INF/lib).

  Parameters:

  uri - The taglib uri

  Returns:

  An array of two Strings: The first element denotes the real path to the TLD. If the path to the TLD points to a jar file, then the second element denotes the name of the TLD entry in the jar file. Returns null if the uri is not associated with any tag library 'exposed' in the web application. This method may be called when the scanning is in one of states: 1. Called from jspc script, then a full tld scan is required. 2. The is the first call after servlet initialization, then system jars that are knwon to have tlds but not listeners need to be scanned. 3. Sebsequent calls, no need to scans.

  Throws:

  JasperException

• uriType

  public static int uriType(java.lang.String uri)

  Returns the type of a URI: ABS_URI ROOT_REL_URI NOROOT_REL_URI
