[weld-issues] [JBoss JIRA] (WELD-1040) Support Java Web Start

Support Java Web Start ---------------------- 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 http:/localhost:8080/weld-webstart-war-0.0.1-SNAPSHOT/webstart/weld-webstart-jar.jar at org.jboss.weld.environment.se.discovery.url.FileSystemURLHandler.handleArchiveByFile(FileSystemURLHandler.java:80) at org.jboss.weld.environment.se.discovery.url.FileSystemURLHandler.handle(FileSystemURLHandler.java:58) at org.jboss.weld.environment.se.discovery.url.URLScanner.scan(URLScanner.java:102) at org.jboss.weld.environment.se.discovery.url.WeldSEUrlDeployment.<init>(WeldSEUrlDeployment.java:39) at org.jboss.weld.environment.se.Weld.createDeployment(Weld.java:130) at org.jboss.weld.environment.se.Weld.initialize(Weld.java:80) at com.example.TestApp.main(TestApp.java:12) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at com.sun.javaws.Launcher.executeApplication(Launcher.java:1914) at com.sun.javaws.Launcher.executeMainClass(Launcher.java:1847) at com.sun.javaws.Launcher.doLaunchApp(Launcher.java:1609) at com.sun.javaws.Launcher.run(Launcher.java:138) at java.lang.Thread.run(Thread.java:680) Caused by: java.util.zip.ZipException: error in opening zip file at java.util.zip.ZipFile.open(Native Method) at java.util.zip.ZipFile.<init>(ZipFile.java:127) at java.util.zip.ZipFile.<init>(ZipFile.java:143) at org.jboss.weld.environment.se.discovery.url.FileSystemURLHandler.handleArchiveByFile(FileSystemURLHandler.java:71) ... 15 more 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(); } // see http://javasourcecode.org/html/open-source/jdk/jdk-6u23/com/sun/jnlp/JNLP... // public JarFile getJarFile(URL url) throws IOException { Method m = cl.getClass().getMethod("getJarFile", URL.class); // returns a reference to the local cached copy of the JAR JarFile jarFile = (JarFile) m.invoke(cl, new URL(urlPath)); urlPath = jarFile.getName(); }
