Support Java Web Start

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:

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)

else

Method m = cl.getClass().getMethod("getJarFile", URL.class);

JarFile jarFile = (JarFile) m.invoke(cl, new URL(urlPath));

urlPath = jarFile.getName();
}
