When I started the new DataStreams the idea was that InputDataStream and
OutputDataStream would be the low-level DataStreams. By low-level I mean
that they would provide an interface that is very basic (e.g. wouldn't have
any support for mime headers) and  easy/efficient to use in building the
core library. InputDataStreamAdapter, StringOutputDataStream,
ByteOutputDataStream, etc.were intended to provide a higher level interface
including support for mime headers.

There were a couple of cases where it made the code much easier if the
low-level DataStreams had limited knowledge of the mime headers being used
by the derived classes. So I added the code but didn't make it public
because I was trying to keep the low-level DataStreams interfaces simple.
Also I thought most people would be using the high-level DataStreams, I
imagine it would have helped if I had written the OutputDataStreamAdapter at
the same time.

Anyway, that is the history behind the code. While the code is better than
the previous version it could probably use some refactoring. So let me know
if you have any suggestions as you are using it.

A FileOutputDataStream is on the list of things todo, I should get to it
soon.

Re: [Beepcore-java-users] sending files in messages

[Erols <tde...@er...>]

Gabe,

I am working on a class called OutputDataStreamAdapter extends
java.io.OutputStream.  It would be accessed from OutputDataStream by method
getOutputStream.  This is analogous to the InputDataStream.getInputStream()
returning a java.io.InputStream extended InputDataStreamAdapter.  I expect
to submit this code back to the project sometime in the near future pending
Hustons approval.  My motivation was so that I could treat the payload of an
outgoing message as a java.io.OutputStream, a more intuitive interface for
what I was trying to do. Actually, sending a file as you were doing, but
would also be able to things like send streaming data over the channel.  My
call sequence would be:  receive a message (ex. <getfile>),  create an ods,
os = ods.getOutputStream(), message.sendANS(ods) , several os.write(data) ,
os.close().

I beleive the OutputDataStreamAdapter would serve as a basis for your helper
class and would simplify your demo code.  Simplified in the sense of
creating intuitive sense.  I expect I will be writing a FileDataOutputStream
helper class as well and will submit it back to cvs.

The mime headers are a different beast.  They seem to be in a funny place to
me as well, in the subclasses.  For example, they are settable in
StringDataOutputStream and ByteDataOutputStream. [aside: I am working from
memory here, so my class names might be a bit off.  I assume you know which
ones I am talking about].  I found myself in a similiar boat as you, that in
order to test my code, I had to create a class called
SettableDataOutputStream, just so I could default the MimeHeaders.

To be honest, I don't quite understand what/why the MimeHeaders are
neccesary in *all* cases anyway.  But I haven't taken the time yet to
investigate either.

Huston may have some reason for this scheme, so hopefully he will enlighten
us.

I will try to catch you two on openprojects Tuesday.

[Beepcore-java-users] sending files in messages

[Gabe W. <gw...@wa...>]

I am trying to send a file in a message using beepcore-java .. I'd like to
do a typical read loop - read from the file, send it "through" the message
outputdatastream, read from the file, send through the message datastream,
etc.

I can use OutputDataStream and create BufferSegments each time I read from
the file. Fine. But OutputDataStream doesn't let me set the MimeHeaders
without subclassing.. (the constructor is protectedEGAD!! Why is this? I
really don't want to have to subclass just to set the mime headers.

Can we just make the constructor for OutputDataStream not protected?

I'm writing demo code and I'm trying to make things as simple as possible.
Another thing I'd like to see is a helper class perhaps that would take a
file or file inputstream and wrap it in a OutputDataStream interface.
i.e.:

new Message(new FileOutputDataStream(new FileInputStream("foo.txt")));

This is relativley high priority for me - I'm working on a book chapter
about beep and it is going to use the beepcore-java libs.. if we could
un-hide the constructor I mentioned above, that'd be the quick-n-easy
solution.

THANKS!!!

Enter this as a bug. If you could please provide some more details about the
failure that would help. Session and Channel are both intended to be
thread-safe so this is probably a bug. The library will send both MSGs
before receiving the RPY for the first MSG but the listener is required to
process them in order so this is valid within the spec.

[Beepcore-java-users] startChannel & threads

[Gabe W. <gw...@wa...>]

Hi people-
	I'm writing a simple little client/server thing in BEEP using two
profiles and I've run into a runtime issue with beepcore that I think
should be addressed. Perhaps I'm not understanding how to use the
startChannel method..
	Basically, I end up firing up two threads and calling
startChannel on the session object (passed in to each thread). This
appears to yield a race condition where each thread ends up causing a
<MSG> to be sent on channel zero without a RPY being received and some
sort of deadlock, with apparently the second channel creation request
failing.
	In short, startChannel doesn't seem to be threadsafe and I think
it absolutely should - not sure if this is a bug or an intentional design
choice.
	I checked the sf site and did not see this as a reported bug or
issue, and I'm not sure what exactly it is (feature or bug).

	-Gabe

[Beepcore-java-users] Re: [idxp-java-developers] idxp4j

[Nathan C. <nc...@bi...>]

I'd like to mention I'm still interested in this, and am trying to convince
an honours student I am supervising (who is working on IDXP) to work on the
java implementation to save me doing work when I have to be concentrated on
finishing my Masters. However, I'd still like to help, and will definitely
contribute my meager coding skills in spare time provided someone can
motivate me (i.e., me!).

Anyone else interested and willing to volunteer for modules? I can assure
the team that provided we can get it going soon, I can incoporate it into an
open source monitoring system I'm working on that will hopefully in beta in
the next few months.

Nathan.

[Ben F. <me...@be...>]

Hey ya'll,

Its been a long time since I sent mail out to the idxp-java lists.  I hope
none of you thought I dropped off the face of the planet :)  
Unfortunately, in the interim, the project to implement IDXP in Java has
been languishing.  Due to serious constraints on my time, I've been unable
to devote the effort to this that it truly deserves.

I'd like to attempt to reengage the people here on contributing to the
project.  Perhaps someone would like to take over as the project lead, if
they think they have real time to devote?  I'm ready to commit more of my
time, but I really need the participation of others.  The CVS module
'idxp4j' should now be the target for any development, and contains a
number of compilable but only partially-functional IDXP classes.  A brief
description of the know issues is in the README.txt file.  Even just
helping me debug and fix the current hanging in the handshake would be a
great help!

Ben

[Beepcore-java-users] new commercial-grade BEEP implementation now available

[Jered F. <je...@pe...>]

Permabit is pleased to introduce PermaBEEP for Java, a commercial-grade
implementation of the Blocks Extensible Exchange Protocol (BEEP). PermaBEEP
is a toolkit that speeds and simplifies development of applications that
depend on network communications.


[Features]

CONFORMANCE: PermaBEEP provides a full implementation of the BEEP
specification and complies with all applicable standards.

PERFORMANCE: PermaBEEP is designed for efficiency, avoiding unnecessary
memory copies and object instantiation.

SCALABILITY: PermaBEEP supports non-blocking extensions to the Java I/O
model (this predates the JDK 1.4 java.nio framework) to support hundreds of
active BEEP channels without a large number of threads.

COMPLETENESS: PermaBEEP simplifies payload handling with its full-featured
MIME parsing and composition tools, along with a lightweight parser for the
"application/beep+xml" MIME type XML subset.

More details are available in the on-line documentation and release notes.


[Availability]

Please visit http://www.permabit.com/permabeep/ to download the software.

Version 0.8 of PermaBEEP for Java has been well tested but under limited
conditions. We encourage you to report any problems encountered when testing
in your development environment. Note that some planned features have not
yet been implemented and that some interfaces may be changed in subsequent
releases.

Additional information is available on the PermaBEEP project pages at
http://www.permabit.com/permabeep/.


[Licensing]

PermaBEEP is available under two licenses, one for open source applications
and the other for proprietary commercial applications. The open source
license is similar to that of the Sleepycat Berkeley DB software, permitting
use of PermaBEEP at no charge only in compatible open source applications.
For all other applications, please contact sa...@pe... to obtain
licensing terms and pricing.


[Acknowledgements]

Permabit extends its thanks to the BEEP Community, and in particular to Dr.
Marshall T. Rose, for designing BEEP and championing it as a standards-track
protocol.

Permabit also thanks Huston Franklin and other Invisible Worlders for
developing beepcore-java, which brought us far enough into BEEP that we
decided to write a new implementation.


[About Permabit]

Permabit, an innovative developer of networked storage software, offers a
distributed data repository that economically blends security, scalability,
and reliability, uniquely addressing a wide range of applications. A
privately held company, Permabit is based in Cambridge Massachusetts.

[Beepcore-java-users] Three API change requests

[Michael F. <mfo...@ny...>]

(I'm using a version synchronized from CVS last night)


Request #1
----------

I'm trying to use the classes:

	org.beepcore.beep.core.event.ChannelListener
	org.beepcore.beep.core.event.SessionListener

in order to clean up various things when sessions and channels are
closed, but with the current design, I can't install these listeners
into the Session object until after creation time.  This leads to a race
condition and missed events.  For instance, suppose I have:

1:	Session session = TCPSessionCreator.listen(port, reg);
2:	MyEventListener listener = new MyBeepListener(); // implements
both listeners
3:	session.addChannelListener(listener);
4:	session.addSessionListener(listener);


Between lines 1 and 2, a bunch of stuff can happen to the session that I
won't be able to detect because my listener isn't installed yet.  

Can the static method TCPSessionCreator.listen(...) be overloaded again
so that there's a version that looks like:

	public static TCPSession listen(int port, ProfileRegistry
registry, 
						SessionListener sl,
ChannelListener cl)
            throws BEEPException;

This way, the listeners can be installed at Session creation time, not
afterwards.


Request #2
----------

The Channel object has a setData(Object) and getData() method so that
applications can store per-channel data with each channel.

Can this be done for the Session object also?  This is especially
relevant for the SessionListener object, which receives a Session in the
EventObject.  I have per-session data that needs to be changed on
sessionClosed() events, but the only way I can find this data now is if
I use a HashMap (using the default Object.hashCode() method in Session).

Request #3
----------

Additionally, if there are multiple channels open in a session, and the
session is closed (due to a disconnect, for instance), no
ChannelListener.channelClosed() events are generated for the channels
which were opened (but now are closed), nor is the
StartChannelListener.closeChannel() method called (these are probably
redundant, since the indicate the same event).  Can this be changed so
that channelClosed events are generated when a session is closed
(perhaps indicating the reason the channel closed in the ChannelEvent
object), and can the redundant methods (ChannelListener.channelClose()
and StartChannelListener.closeChannel()) be cleaned up?

Every time I have seen this it has been a jsse installation problem. Verify
the settings in your java.security file to make sure you have added the jsse
as a provider as per the jsse installation instructions. To validate that it
is a jsse installation problem you can try running the jsse samples and they
should fail in the same way.

[<li...@co...>]

Ugh, I think things got mixed between replies from the mailing list and 
personal replies (damn I hate this new reply-to format/Lotus Notes/both).

Earlier, I made a reply to Steve suggesting to add the line below anywhere 
in the main() method (previously referred to as the 'immortal line'):

   Security.addProvider(new com.sun.net.ssl.internal.ssl.Provider());

If it doesn't compile, it will probably be because the JSSE is not 
included in the classpath.

By the way, if you don't expect to use TLS in your application, just 
remove that line and it'll work fine since the echo server doesn't really 
care much, it just sorta works.

Ling Lo

Aha!  Yes, the beepd class was compiled with some old version of the beep
lib.  I ran into the exact same problem!  Apparently they moved the
namespaces around, updated the beep library, and the beepd java source.  But
they forgot to recompile the beepd class file so it is searching in the
wrong namespace for the beep lib.

All that is a long winded way of saying, you need to recompile the beepd
(Bing) java file that came with beepcore.  Once you do, the problem goes
away.  Since it is a single file, you should just be able to do a javac
including the beep libs in the classpath.  I believe the example sources are
already updated so its just a matter of recompile... If it won't recompile,
check the namespaces it uses for the security classes.

Will do, but the only problem is that I'm just using

need to build a method for it or just add the lines (I

Persistence pays I guess... :)  If you send the exception and the
commandline you used I might be able to help you narrow it down.  I'm not a
committer on beep-core but I also ran into trouble getting beepcore java
running out of the box.   We should probably categorize the problems, fix
the bugs in the packaging and installation docs, etc so this thing works
from the unzip without hassles.

Is any commiters or beepcore java reading this list/active?  Is the project
dead?

[Beepcore-java-users] more problems with examples in beepcore java

[Steve <yud...@ya...>]

Hi again.

I think I've got everything working except now I get
an error message saying:
TLS algorithm not found. probable cause JSSE provider
not added to java.security file

or something to that extent.

Yeah classpath was correct (I think) but I checked and
found that I was missing a couple of classes that were
needed. Downloaded them but I'm still having a lot of
trouble. 

Before I get into too much detail, can somebody tell
me where (in a linux environment) building
beepcore-0.9.06 with ant is supposed to put
everything. (namely the jar files). are they (the jar
files) supposed to be put under $JAVA_HOME or just
under the downloaded package. thanks

Steve

Are you sure?  :)  That's a standard DOM class that should be part of your
XML parser jar... Are you absolutely positive?  Make sure Xerces.jar or
whatever you're using is properly in there.  Send your command line and the
full stack trace if you're still positive.  If you set CLASSPATH in your
environment also include the output of 'env'

-iain

Hi,
I've isntalled Beepcore-java on a linux box and tried
to run the examples but I get an error whenever I try
to run Beepd: java org.beepcore.beep.example.Beepd
-config beepd-config.xml
Exeption in thread "main"
java.lang.NoClassDefFoundError: org/w3c/dom/Node

I'm quite sure I've set my CLASSPATH correctly

Thanks in advance

Steve
