SLP DA status

[Chris Custine <cc...@apache.org>]

Hi All,
I was wondering if there is any active work being done on the SLP DA for
Apache Directory?  Its been a while since I have seen any traffic on this,
but I am hoping it is still active so if Jan or anyone else has an update on
this it would be welcome.

Thanks,
Chris

I've spoken to Julien from MINA and I think he can help with the MINA
related aspects.  I was hoping we could at least get you as a committer
Lorenz.

It would be great if you could send out a message here when the source
becomes available.  I think "protocol-slp" is definitely what I have in mind
but it sounds like it won't be too much of a stretch to make that happen so
hopefully we can work that out.

Thanks for the info!

Thanks,
Chris

That was the idea initially, I just built it standalone first so that I
could "plug in" various backends.

it should actually be fairly straightforward. jSLP provides a
getDirectoryAgent() method which kicks off the SLPCore, initializes all
the MINA stuff and starts running... So it's just a matter of plugging
it in the right spot in the directory architecture ( I guess
protocol-slp) and getting the SLP and ADS config "in synch". I just
didn't want to duplicate code by creating both a standalone jSLP
implementation with an embedded ADS (can of course also be "opened" by
starting the networking layer) and an ADS with embedded jSLP...

I am handing in the thesis on thursday, then i'm off for a weekend of
celebrations ;) i hope to release next week if possible so that you can
look into it and provide feedback. but i have to check with jan and the
folks at the ETH first (legal mumbo-jumbo)

That's great.  How about contributing it to Directory?

I will contact some people to make sure we can add this code to MINA before
2.0.  Emmanuel also may comment on this.

Yes this can be done.  Was just hoping something can form about SLP here at
Apache.  Regardless the story goes on and anything is possible.

Hi Chris

jSLP 2.0, which includes the DA, is basically finished and should be
released within the next few weeks. The current implementation can use
an embedded ADS as a backend, but currently jSLP is still a standalone
project. The out-of-the-box jSLP DA uses a simple in-memory HashMap, but
the code for the ADS (1.5) backend will also be released as a separate
package.
jSLP 2.0 was developed on top of MINA, which does not support multicast
as of yet. I did however whip up the necessary MINA code for
multicasting over APR. The code was posted to the MINA issue tracker a
while back, but no news from the MINA guys yet. I don't know what we
will do there, maybe release that code on the jSLP page as well. That
multicasting code didn't work for me under windows, probably due to a
problem in tomcat native, but it worked fine under linux (32 and 64 bit).
jSLP is an extension of jSLP and a lot of changes were made. While the
DA part seems to work well, some features have still to be implemented,
such as localization support and SLP security functionality (which also
seems to be FUBAR in OpenSLP).

I guess "reversing the roles" by using jSLP to build an ApacheDS DA
shouldn't be too hard, just a matter of retrieving a DirectoryAgent von
jSLP within ADS...

Hope that info helps,
Lorenz
