OK, the spec http://java.sun.com/javase/6/docs/technotes/guides/jar/jar.html says "A JAR file is essentially a zip file that contains an optional META-INF directory." So the META-INF directory may not always exist.
Also, I couldn't find any mention in the spec (or other docs from sun) of file magic for jar files. I believe the 0xcafe magic match is really for java class files. Most interesting jar files (especially executable jars) will have at least one class file, but once again I don't think any particular location in the file can be assumed. -- KDE always associates *.jar with the zip mime type https://bugs.launchpad.net/bugs/309778 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
