Hi, (I added the classpath mailinglist to the CC.)

And I am only moving very, very slowly forward with reworking and understanding(!) the VM interface issues. So I don't think just plugging Classpath into Kaffe will happen anytime soon. I have recently been thinking about Kaffe and GNU working more together. Firstly I think it would be a good idea if you get the following GNU packages working with Kaffe. This should be easy since it doesn't really need any real Kaffe integration, just checking that it all works (and some have nice testsuites). It will make the Kaffe 'product' more complete: - GNU Classpath-tools, standard tools Not yet released, but important bits, javap, javah, javadoc are here: <http://savannah.gnu.org/cgi-bin/viewcvs/cp-tools/cp-tools/> <http://savannah.gnu.org/cgi-bin/viewcvs/cp-tools/gjdoc/> - GNU JAXP, Sax and Dom implementations and interfaces. http://www.gnu.org/software/classpathx/jaxp.html - GNU Crypto a crypto library that can also be used as crypto provider. <http://www.gnu.org/software/gnu-crypto/> - Kawa, the java based Scheme system. Contains lots of utility packages. <http://www.gnu.org/software/kawa/> - GNU Paperclips, Servlet and JSP engine. http://www.gnu.org/software/paperclips/ - gnu.regexp, Regular Expressions for Java http://www.cacas.org/java/gnu/regexp/ - GNU Getopt in Java http://www.urbanophile.com/arenn/hacking/download.html Then there is the following list of GNU Classpath 'easy targets' (meaning, no-brainers, just use the complete package): - java.awt.color - java.awt.dnd - java.awt.geom - java.awt.im - java.awt.image.renderable - java.beans.beancontext - java.util.logging [1] - java.util.prefs [2] - javax.accessibility - javax.naming, javax.sql, javax.transaction [3] [1] Please ask Sascha Brawer ([EMAIL PROTECTED]) about the status. [2] I wrote this but never used it, it is not completely finished, missing a real backend. But I have heard some reports from people that used the MemoryBased backend successfully. [3] Not completely merged from libgcj, but you can get it from the GCC distribution. There very limited api doc which is why I don't like to import it in Classpath yet. I did write some documentation for some of the classes that were imported but not all. Minimal stuff to support JDBC3.0 is in Classpath. There are also a lot of javax.swing stubs, but I don't know how useful they are except to get more things to compile. And you could also look at the java.nio stuff but I have never really played with it and don't know the status. But how to go from there I don't know precisely. Things you might like to play with: - You already mentioned the new collection classes (IdentityHashMap, LinkedHashMap, LinkedHashSet, WeakHashMap and RandomAccess support). - java.lang.reflect.Proxy (this might make Jython run) - Look at the Throwable VM interface and adapt it for Kaffe, this will give you exception chaining and StackTraceElement. - See if the pure jave java.util.zip (jazzlib) library is something for kaffe. - Likewise for the pure java java.math implementation (said to be faster then going through JNI). - Security Permission model is better supported in Classpath then in Kaffe (but completely untested!) - Transvirtual donated the java.rmi implementation to the FSF al long time ago it has seen a couple of fixes and additions (some of the Orp patches are still waiting to be merged into Classpath). I don't know if Kaffe kept up to date with this version. - Michael Koch ([EMAIL PROTECTED]) recently did a lot of java.net 1.4 updates but I don't know if he has JNI support yet (he started with the libgcj version which uses CNI). We will have to make sure the we have good Mauve tests so you can see if replacing things fixes or breaks things in Kaffe so please run and contribute to Mauve regularly :) And I would like to ask that improvements to classes that you import are contributed back to the GNU Classpath project as described at: http://www.gnu.org/software/classpath/doc/hacking.html#SEC2 Cheers, Mark _______________________________________________ Classpath mailing list [EMAIL PROTECTED] http://mail.gnu.org/mailman/listinfo/classpath
