Example 91 with URLClassLoader

use of java.net.URLClassLoader in project lucene-solr by apache.

the class SolrResourceLoader method addURLsToClassLoader.

private static URLClassLoader addURLsToClassLoader(final URLClassLoader oldLoader, List<URL> urls) {

use of java.net.URLClassLoader in project lucene-solr by apache.
