[Sync4j-users] How to sync db data on sync4j

[Mr Y. L. <yil...@ya...>]

  Dear Sync4j User:

  I can now use sync4j example PostSyncML.java to sync
data from file data sources by modifying the follwing
lines on s4j_init.xml and s4j_modification.xml
    
  <Target><LocURI>vCard</LocURI></Target>
     
  However, I got the problem on sync data from db data
sources. What kind of modifications do I need to make?

  If anyone knows that, please let me know. I will
appreciate it.  

  Robert Lin

one status for the message and one for each alert, along with the alerts 
the server will issue.

every sync command has a target and a source. the client will send a sync 
command for each database (except 1-way from server). this way, client and 
server can sort out what belongs to which database and also the sync type 
previously defined. of course, client and server must store the sync type 
they choose in the init phase and send or not send items accordingly...

[Sync4j-users] Database selection

[Stefano F. <ste...@li...>]

Hi All,
I would like to select an open source database to use as the reference
database for Sync4j.
I am inclined to use PostgreSQL for it looks very featured, mature and,
above all, it is easily distributed inside cygwin. But I would like hear
other suggestions and experiences with PostgreSQL or other databases.
For instance, a good choice could be MySQL...

Any thoughts? Any good/bad experience with any open source db? Any
advice?

Thanks in advance,
    Stefano

[Sync4j-users] Multiple database Sync within single session

[Chintan S. <chi...@bc...>]

Hi,

According to Chapter 4.1 Initialization requirements for Client:
"The databases, which are required to be synchronized, are indicated in the 
separate Alert Commands. i.e., for each database, a separate command MUST 
be included in the SyncBody..." of SyncML Sync Protocol.

Q: Lets consider a scenario where a client requests for synchronizing 3 
databases with the server. Client sends <Alert> command with their type of 
sync requests for each of their database.
         eg. 200 (2-way sync) for db a, 202 (1-way from client) for db b, 
204 (1-way from Server) for db c.

Questions:

1. What will be the response from the server ? (I guess, it will respond 
accordingly to the response status of type of sync accepted by server for 
each db).
2. If clients are granted with the requested sync type, what kind of body 
is expected by the server in next package from client ?? Body containing 
Status + Sync ! (Sync for db b) but opposed to rule for 204 (sync for db c 
- as it does not want any Sync within the client body !) Hence the server 
will be in a dilemma :-/
3. Or does the client syncs databases one after another ? i.e. First 
performs sync with db a, on successful completion performs b & c.

[Sync4j-users] Re: Kxml: multiple code pages in kXML?

Hi Nicola,

it should not be too much effort, as far as I remember
I have tried to keep the code easily extensible in this direction.

I would like to add this feature, but I still did not
find time to add WBXML support to 2.x version of kXML,
and for me that would be the first thing on the
agenda for KXML/WBXML....

Best,
Stefan

[Sync4j-users] multiple code pages in kXML?

[Nicola F. <ni...@lu...>]

hi

I am an active developer of the sync4j project [1]. This project
implements the SyncML specification, which uses besides plain XML also
WBXML to synchronize two devices.

To accomplish this, I am looking now for a WBXML parser written in Java
which supports more than one WBXML code page. Unfortunately, until now
we haven't found one - so I'd like to ask you: Of what dimension would
such an enhancement to kXML be? Is it a matter of adding some code here
and there or would we have to redesign the whole thing?

any hints would be appreciated!

RE: [Sync4j-users] WSP Binding Status?

[Darryl C. <Dar...@op...>]

Sounds like you've got it....

Two code spaces, three code pages.....
FD1 has the two code pages SyncML (0x00) and MetInf (0x01)
FD2 only one: DevInf (0x00)

I'm afraid I don't have a recommendation...... I looked (a while ago), and
pretty much everything I found had the code page problem.  I didn't look
into how much work it would have been to address that, and it was at least 6
months ago anyway....

point taken. :)

SycnML has two code _spaces_ with a total of three code _pages_ - this
seems quite a lot to do!

seems logical to me - the two devices sync'ing know what they talk
about, so they simply omit the string table.

as far as I understand, SyncML has the WBXML public identifiers FD1
(SyncML and MetInf) and FD2 (DevInf) (or am I missing one?), which are 
'source spaces':

FD1 has the two code pages SyncML (0x00) and MetInf (0x01)
FD2 only one: DevInf (0x00)

:)

enhancing kXML v1 could be a possibility - gotta ask in their mailing
list about that one.

you talked about other WBXML parsers which don't support multiple code
spaces / code pages yet - which one would you recommend to enhance?

thank you for those help-lines, I will come back to them (and you) when
I am really desperate! :)$

first I had to dig into the logic & sources of sync4j and now it seems
that I can right away dive into kXML v1 - I'll have to set boundaries,
after all it's only a _term paper_!

hi darryl

I've spent about 2 hours getting all the bits and pieces from various
documents of different projects and specifications - I hope it is a step
forward towards WAP support for sync4j.

altough I hope I have no really nasty bugs in my rather lengthy email,
critics & correction are always welcome!

kXML v1.x does indeed support WBXML (as stated in [8]) - while version 2
does not (first paragraph in [9]).

I google'd around for WBXML & Java and found an example where kXML was
used to transform WBXML to XML and the other way 'round [1]. a small
Java class doing this can be found at [2].

the WBXML specification [4] says that "A binary XML document must
include a string table immediately after the public identifier." and:
"Various tokens encode references to the contents of the string table."
[6] - so much for the concern that those code pages would have to be fed
to the WBXML parser.


<dgc> This misses one issue - that default strings are specified in the
DTD/Public Identifier description, not the string table.  The C Toolkit,
available at Sourceforge, has to have all the SyncML specific identifiers
embedded in it.  That doesn't mean its difficult, but there is more than the
string table involved, and you have to switch pages (and spaces).  In
reality, when syncing with devices, most implementations have an empty
string table - they want the minimum bytes for the minimum processing, and
they aren't going to try to extract any common strings beyond the defaults.


regarding your concern of multiple code spaces:
"This version of the SyncML representation protocol specification maps
all the SyncML related DTDs into a single WBXML code space." [3]

this single code space divides into two code _pages_:

1. SyncML
2. MetInf

in a WBXML stream, a SWITCH_PAGE token can switch the current page.

<dgc> Unfortunately, the representation protocol is not the entirety of
SyncML.  The Device Info DTD/Doc is in its own code space, so you have to
deal with both, and as per the JavaDocs, multiple code pages are not yet
supported.
"This version of the DevInf DTD specification is associated with the WBXML
code space FD2 and the formal public identifier -//SYNCML//DTD DevInf
1.1//EN."


apart from these website tutorials, I think that parsing a WBXML stream
to produce plain XML should not be _that_ difficult, if we fail to find
an existing parser capable of transforming SyncML WBXML. given those
code-pages (which are delivered in the WBXML stream like specified in
[6]), it would have to get the first XML tag, look it up in the string
table, write out the full XML tag, get the next byte etc.
but this should only be necessary in the last resort.


<dgc> I think that is a loaded question - after all, if it's that easy, how
much value would kXML be for you in that case :-).  Anyhow, presumably you
can just enhance kXML v1 to support multiple code spaces, or add it to kXML
v2, (or port the C toolkit to java) but I leave that as an exercise for the
reader.....


> How certain are you of your support for WBXML?

I am working on a project at my university to provide exactly this. the
idea I had so far (I am still in planning stage, altough coding
hopefully won't take long) is to use kXML [1] to parse the WBXML coming
from the WAP device and transform it into (human readable) XML and then
feed it to sync4j for processing. the returning XML stream from the
sync4j syncengine (developed by my colleague David Buchmann of the same
university [2], we'll check in the new sources soon) is transformed
again by kXML into WBXML, so that the WAP device understands it.

if you want to help me doing that, I'll be thankful.

Re: [Sync4j-users] build file problem?

[<Dav...@ES...>]

hello TaiYen,

> I am found two build files (./build.xml and ./build/build.xml), which 
one is
> correct?
the old version of readme told that the files in ./build/ are the correct 
files.
http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/sync4j/sync4j/README.txt?rev=1.3&content-type=text/vnd.viewcvs-markup

@sso it would be a good idea not to overwrite this old readme.txt with the 
j2me information but to add it to the file -  or to choose different 
filenames...

the build problem i do not know. perhaps stefano has an idea?

regards,david

[Sync4j-users] build file problem?

[TaiYen H. <h24...@ma...>]

Hi

I want to use sync4j in our undergraduate project and get sync4j source code
from CVS.
But, when I try to use Ant build sync4j.
I am found two build files (./build.xml and ./build/build.xml), which one is
correct?

Another problem is when I used ./build/build.xml (I think the correct build
file is this one)
got following error message :

config:

${sync4j-framework-jarfilename}:
   [delete] Deleting: C:\Program Files\Apache Tomcat
4.0\webapps\sync4j\output\sync4j-framework.jar
      [jar] Building jar: C:\Program Files\Apache Tomcat
4.0\webapps\sync4j\output\sync4j-framework.jar

${sync4j-clientframework-jarfilename}:
   [delete] Deleting: C:\Program Files\Apache Tomcat
4.0\webapps\sync4j\output\sync4j-clientframework.jar
      [jar] Building jar: C:\Program Files\Apache Tomcat
4.0\webapps\sync4j\output\sync4j-clientframework.jar
      [jar] Manifest is invalid: Manifest sections should start with a
"Name" attribute and not "Created-By"

BUILD FAILED
file:./build-share.xml:293: Invalid Manifest: C:\Program Files\Apache Tomcat
4.0\webapps\sync4j\src\metadata\sync4j-clientframework-JAR-MANIFEST.txt


Please give me some suggestion, thanks.

Re: [Sync4j-users] Use with Motorola StarTAC

[Simon So <ss...@cs...>]

Hi Julia

SyncML is a mobile device data sync protocol, formatting data into XML doc
and transported over either http, wsp or obex (infrared/bluetooth).

You can use libraries like sync4j or ksync (from enhydra, yet another
syncml implementation) to format/interpret your data.  As far as
transporting over the serial port, it's not mandated by the syncml
protocol.  You may write your own transport layer.

Best,
Simon

[Sync4j-users] Use with Motorola StarTAC

[Julia A. C. <ju...@Ma...>]

I've been working on a java interface to deal with my cell phones
Phonebook database (http://jStarTalk.MageNet.com)  And I'm a little
confused about what SyncML is.  Could I simplify my adventures
(currently I'm reverse engineering the data that goes across the serial
port) by using SyncML?

Any hints would be appreciated.

Do you mean j2me library?  Go to wireles.java.sun.com and download the
wireless toolkit.  It's got midp_api.zip.  I also talked about it in my
README.txt.

Just an odd question..... I haven't worked with the j2me apis yet, however
last summer I worked with the SuperWaba classes, and developed a few things
like ant scripts, etc. for them.  I tried looking for a jar file comparable
to the ejb.jar, is there a j2me.jar somewhere at java.sun.com?

I like the Enhydra stuff, but they change their licenses to suit their
moods... I dropped instantdb for that exact reason.
