Example 2 with EmptyResourcesClassLoader

use of org.apache.openejb.core.EmptyResourcesClassLoader in project tomee by apache.

the class DeploymentLoader method addBeansXmls.

public static void addBeansXmls(final WebModule webModule) {
    final List<URL> urls = webModule.getScannableUrls();
    // parent returns nothing when calling getresources because we don't want here to be fooled by maven classloader
    final URLClassLoader loader = new URLClassLoader(urls.toArray(new URL[urls.size()]), new EmptyResourcesClassLoader());
    final List<URL> xmls = new LinkedList<>();
    try {
        final URL e = (URL) webModule.getAltDDs().get("beans.xml");
        if (e != null) {
            // first!
            xmls.add(e);
        }
        xmls.addAll(Collections.list(loader.getResources("META-INF/beans.xml")));
    } catch (final IOException e) {
        return;
    }
    final CompositeBeans complete = new CompositeBeans();
    for (final URL url : xmls) {
        if (url == null) {
            continue;
        }
        mergeBeansXml(complete, url);
    }
    if (!complete.getDiscoveryByUrl().isEmpty()) {
        complete.removeDuplicates();
