> Key: WELD-1040
> URL: https://issues.jboss.org/browse/WELD-1040
> Project: Weld
> Issue Type: Bug
> Components: Java SE Support
> Affects Versions: 1.1.4.Final, 1.1.5.Final
> Reporter: Alexandre Gattiker
> Attachments: weld-webstart-bug.zip

>
> ClassLoader.getResources("META-INF/beans.xml") returns remote server URLs in
> the format "http://...";
> Weld's FileSystemURLHandler tries to open these URLs as files, which leads to:
> java.lang.RuntimeException: Error handling file

> I am attaching a demo project that also contains a proposed fix, using
> com.sun.jnlp.JNLPClassLoader#getJarFile(URL) to retrieve the location of the
> locally cached copy of the JAR. As this is an internal class it is accessed
> by reflection. The getJarFile method only exists in JRE 6, not in JRE 5.
> Add to org.jboss.weld.environment.se.discovery.url.FileSystemURLHandler:
> if (urlPath.startsWith("http:") || urlPath.startsWith("https:")) {
> ClassLoader cl;
> if (Thread.currentThread().getContextClassLoader() != null) {
> cl = Thread.currentThread().getContextClassLoader();
> } else {
> cl = getClass().getClassLoader();
> }
> Method m = cl.getClass().getMethod("getJarFile", URL.class);
> JarFile jarFile = (JarFile) m.invoke(cl, new URL(urlPath));
> urlPath = jarFile.getName();
> }
