Example 8 with JarURLConnection

use of java.net.JarURLConnection in project sling by apache.

the class OriginalTldLocationsCache method scanJars.

/*
     * Scans all JARs accessible to the webapp's classloader and its
     * parent classloaders for TLDs.
     *
     * The list of JARs always includes the JARs under WEB-INF/lib, as well as
     * all shared JARs in the classloader delegation chain of the webapp's
     * classloader.
     *
     * Considering JARs in the classloader delegation chain constitutes a
     * Tomcat-specific extension to the TLD search
     * order defined in the JSP spec. It allows tag libraries packaged as JAR
     * files to be shared by web applications by simply dropping them in a
     * location that all web applications have access to (e.g.,
     * <CATALINA_HOME>/common/lib).
     *
     * The set of shared JARs to be scanned for TLDs is narrowed down by
     * the <tt>noTldJars</tt> class variable, which contains the names of JARs
     * that are known not to contain any TLDs.
