URLClassLoader.java: Find the JarEntry via the JarFile.

Sun Aug 20 09:51:48 2000  Anthony Green  <green@redhat.com>

        * java/net/URLClassLoader.java: Find the JarEntry via the JarFile.

        * java/net/JarURLConnection.java: getEntry doesn't take any
        arguments.  Return null if element is null.

        * java/util/zip/ZipFile.java (getInputStream): Read the compressed
        size from the archive, not the inflated size.

        * java/util/jar/JarFile.java (getEntry): Don't recurse.  Call
        java.util.zip.ZipFile.getEntry.

        * gij.cc (help): Change sourceware reference to
        sources.redhat.com.
