The old lib-gnu.getopt-java provided only class files in
/usr/share/java/repositories/. I remaind it for backward
compatibility. However if nobody use them, class files should be
removed.

BTW, how can I find the packages which depend lib-gnu.getopt-java?

You are correct:)
You should provide only jar file.

I should change getopt;) html/ is good place:)

But, I like separated package for javadoc and manual like
libnbio-java-doc though I don't finish some of my packages.
lib*-java-doc packages be discussed debian-java (but I forget
where...).

BTW, javadoc place are disscussed other thread:
http://lists.debian.org/debian-java/2001/debian-java-200111/msg00012.html

But currently, javadoc is placed individual directory.

There are other native interface for Java like CNI(cygnus native
interface) and KNI (kaffe native interface). That's the reason why I
support /usr/lib/java/jni for JNI.

One more thing, JNI will be improved for JDK1.4.
http://java.sun.com/j2se/1.4/docs/guide/jni/jni-14.html

So, maybe we should provide following two directory:
    /usr/lib/java/jni-1.2
    /usr/lib/java/jni-1.4

IMO, You should not defined it. Because JNI libraries are used by only
Java applications. Java applications should define $LD_LIBRARY_PATH
when they are executed.
