http://issues.apache.org/bugzilla/show_bug.cgi?id=30339 Jar task can create mysteriously broken jar files in 1.5.1, 1.6.2 Summary: Jar task can create mysteriously broken jar files in 1.5.1, 1.6.2 Product: Ant Version: 1.6.2 Platform: All OS/Version: Solaris Status: NEW Severity: Major Priority: Other Component: Core tasks AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] Okay, this one is strange. I've got an Ant build.xml file that builds a jar file containing 481 entries, built up from several subdirectories. If I take the produced jar file and put it on the web site, Safari on Mac OS X 10.3.4, Firefox on Fedora Core 2 and Windows 2000, and IE 6 on Windows 2000, against Java 1.4.1, Java 1.4.2, and Java 1.5.0 beta 2, all refuse to launch the applet that uses this jar file for its class files and resources.. I get a message saying that the entry point class can not be found, and I see in my web server that, after retrieving the jar file, the client JVM tries to load the entry point class directly. BUT, if I take the Jar file on my Solaris system, expand it with 'jar xf', then rejar it with a matching 'jar cf', all of the above platforms find the entry point class properly in the rejar'ed jar file. There's something about the Jar file that Ant is producing in this case that just won't go, even though it obviously contains everything necessary for proper execution when I take it through a roundtrip using Sun's jar tool. When I run both jar files through zipinfo, I see the following differences: The Ant-produced jar file has file types of 'unx', and the class files are very much out of order. A sample zipinfo excerpt is as follows: -rw-r--r-- 2.0 unx 264 b- defN 26-Jul-04 19:25 arlut/csd/ganymede/float_field.class -rw-r--r-- 2.0 unx 618 b- defN 26-Jul-04 19:25 arlut/csd/ganymede/invid_field.class -rw-r--r-- 2.0 unx 290 b- defN 26-Jul-04 19:25 arlut/csd/ganymede/ip_field.class -rw-r--r-- 2.0 unx 262 b- defN 26-Jul-04 19:25 arlut/csd/ganymede/num_field.class -rw-r--r-- 2.0 unx 915 b- defN 26-Jul-04 19:25 arlut/csd/ganymede/pass_field.class -rw-r--r-- 2.0 unx 1160 b- defN 26-Jul-04 19:25 arlut/csd/ganymede/perm_field.class -rw-r--r-- 2.0 unx 636 b- defN 26-Jul-04 19:25 arlut/csd/ganymede/string_field.class 483 files, 1377893 bytes uncompressed, 604275 bytes compressed: 56.1% With command line jar from Java 1.4.2_05, I see entries like: -rw---- 2.0 fat 1570 bl defN 26-Jul-04 19:29 org/xml/sax/helpers/AttributeListImpl.class -rw---- 2.0 fat 934 bl defN 26-Jul-04 19:29 org/xml/sax/helpers/LocatorImpl.class -rw---- 2.0 fat 893 bl defN 26-Jul-04 19:29 org/xml/sax/helpers/ParserFactory.class 481 files, 1377635 bytes uncompressed, 604097 bytes compressed: 56.1% I'll include as attachments the good jar file produced by 'jar', the bad jar file produced by Ant, and the html file used to launch the applet. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
