Alexandre Gattiker updated WELD-1040:
-------------------------------------
Description:
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();
}
