Examples of org.apache.tomcat.util.scan.Jar

org.apache.tomcat.util.scan.Jar
Provides an abstraction for use by the various classes that need to scan JARs. The classes provided by the JRE for accessing JARs ( {@link java.util.jar.JarFile} and{@link java.util.jar.JarInputStream}) have significantly different performance characteristics depending on the form of the URL used to access the JAR. For file based JAR {@link java.net.URL}s, {@link java.util.jar.JarFile} is faster but for non-filebased {@link java.net.URL}s, {@link java.util.jar.JarFile} creates a copy of the JAR in thetemporary directory so {@link java.util.jar.JarInputStream} is faster.

            if (!jarFound) {
                jarFound = true;
            }
            boolean found = false;
            Jar jar = JarFactory.newInstance(urlConn.getURL());
            URL jarURL = urlConn.getJarFileURL();
            try {
                jar.nextEntry();
                for (String entryName = jar.getEntryName();
                     entryName != null;
                     jar.nextEntry(), entryName = jar.getEntryName()) {
