I haven't heard anything for a long time from Rinalldo, but I think to
remember, that he was successful in the end. nevertheless I haven't seen
his results up to now

What you are planning sounds really promising. Especially the
Firefox-Extension would be fantastic.
If you have more concrete questions, please don't hesitate to ask.

[Tm4j-tmnav-dev] Any Progress on Applet?

[don u. <don...@ya...>]

Hello, I'm new to this list, and TMNav in general. 
I read the exchange between Christoph Froehlich and
Rinalldo Yasahardja with great interest, as I'm also
trying to put together an Topic-Map viewer applet, and
ultimately a Firefox Extension of same. Ideally I'd
like to have the graph viewer applet in a separate
frame, loading XTM data off the web page.

Anyways, I was wondering if any progress had been made

since the aformentioned exchange, and if there was any
additional code available for me to look at. 

Not too many questions now, until I spend more time
with the code, but any resources that anyone wants to
send my way would be greatly appreciated. 

I look forward to greater involvement with this
project in the future. Thank you for your time.

Cheers,
Don Undeen

Hm. There is no *official* way to access any TopicMapObject from inside
of tmnav. TMnav operates on an AbstractModel provided by panckoucke.
TMNav does not know anything about "TopicMapObjects".

This was a design decission and  I still think its ok, if you use TMNav
as a Navigator, but since people start to implement editing features in
tmnav, this turns out to be a rather severe issue. Maybe I should
reconsider.

Nevertheless, it is possible to access the topicmap. It is a sort of a
hack and please keep in mind, that it is not part of the api and may be
broken in future versions, especially in next versions of panckoucke.


I paste you example code below. You need to create an instance of
AccessTopicmapHack(NavContext) somewhere in your tmnav-initialisation
code.

Hope it helps

Re: [Tm4j-tmnav-dev] tmnav extended to applet

[Rinalldo Y. <ry...@cs...>]

Hi all,

does anyone know how i can get a reference to the topic map inside tmnav ? 
or to get a copy of it ? I need to iterate through it to check whether a 
particular topic is already contained inside the currently opened topic 
map ?

thanks in advance

ui. ui. 
not really.

What happens, 
 - if you're running the applet without the -f option?
 - if you're removing the line "session.storeSession();" from
TMNav.closeInstance()?

using this method causes TMNav to crash even on the first attempt to run 
it (the message is still the same)

using this method still causes TMNav fail to load the second time.

Re: [Tm4j-tmnav-dev] tmnav extended to applet

[Christoph F. <cf...@fo...>]

Hi Rinalldo

I'm pretty sure that the reason for this is the potential asynchronious
behavior of the Preferences implementation.

I guess you are still running TMNav-Applet with the -f option? And
removed the call to System.exit(int);

If so, please try to add a call to sync in TMNav.clearSessionData():
After that the try - block should look roughly like this:
            try {
                String path = tmnavRootNode.absolutePath();
                tmnavRootNode.removeNode();
                tmnavRootNode.sync(); // new call to sync
                System.out.println("Removed Session Data from path " +
		...

If this does not help, try to add the sync call also to
TMNav.closeInstance(int), just after the line:
  session.storeSession();

(For the latter case you need to access tmnavRootNode just as in
clearSessionData().)

Hope that helps
c

No, because the applet has been signed and apparently, the one that is 
causing the IE to crash when TMNav is closed is because TMNav called 
System.exit

System.exit is not allowed to be called normally on applet but since the 
applet is signed, then calling it causes the IE browser to be closed

So, do you have any suggestion to close TMNav rather than calling 
System.exit(int) ?

Oh. Dont't you get exceptions from the applet?

- System.exit(int) is called in TMNav.closeInstance(int). The
customListener for window clsing is implemented in the constructor of
TMNavMainFrame.

If removeNode() did not fail, you should see a message beginning with
"Removed Session data..."
If it fails, you should see a stack trace. But you see neither, correct?

Another question. Did you try to run TMNavApplet without the -f option?

And: If you don't need the session to be stored, you can remove
session.storeSession() from TMNav.closeInstance(). Just to see what
happens.

Re: [Tm4j-tmnav-dev] tmnav extended to applet

[Rinalldo Y. <ry...@cs...>]

Sorry, a bit lenghty mail here...

for what I did, in summary:
create an Applet class (called TMNavApplet in my case), then override 
the init() function. That class should extends Applet. Inside the init() 
function, you then do what you normally do in your main function, that is, 
in case of TMNav, just move the content of main function inside the init() 
function. As you know, TMNav can be run with several options such as -f 
(which perform factory startup), etc. You then create a html page similar 
like this:

<html>
   <applet code="org/tm4j/tmnav/app/TMNavApplet.class" archive="all.jar" 
height=200 width=200
     alt="if this run, u see tmnav">
   <param name=option value="-f">

   <!-- put the path to the server here (URL)
        example: http://www.cse.unsw.edu.au/~ryas138/index.xtm -->
   <param name=filename value="pattern_v1.xtm">
   Your browser is completely ignoring the &lt;APPLET&gt; tag!
   </applet>
</html>

you then call the getParameter function inside your TMNavApplet class to 
access the value passed by parameter (in this case, 
getParameter("option") would return "-f")

the filename is for testing so TMNav can grab the file from the server.
you should also modify the logging.properties file path so that it is 
grabbed from the server (rather than the client, like the current TMNav 
behaviour), that way you remove all security issues that took me 2 weeks 
to solve... =)

I would love to let you see it works on public but I would have to ask 
permission first. Currently, since this is only for internal use, I doubt 
connection outside the working environment will be allowed. But I can 
always send you the development so you can play around with your own 
server. But I didnt do the integration with the server bit, so I wont have 
a clue about it. Let me fix this issue first though... =)

> As consequence to clicking the window closing button, TMNav calls

I did searches and found that Applet does not normally allow 
System.exit(int) to be called. But I am still confused about this and will 
look into it this week. Do you implement window closing button with your 
custom listener ? If you do, do you know in which file ?

could be but I doubt it though. In my case, there are times when I close 
TMNav applet but it doesnt crash the browser. However, when I tried to 
invoke the applet again, it says Node Removed (may be it caught an 
exception or something). However, I am a little bit suspicious with the 
clearSessionData() in TMNav.java . In my case, I force TMNav to 
always run 
using "-f" parameter, which calls clearSessionData(). However, something 
just prevent of running TMNav more than once. There is also a chance that 
when the window close button is closed, the applet might not free the 
resources used properly, but I dont know about it too...

but my suspicion is in the line that says TMNavRootNode.removeNode() 
in clearSessionData() since 
the msg said Node Removed and TMNav failed to start.

In other words, users can now log in to the server, then run TMNav once, 
and hope that when they close TMNav, it doesnt crash the browser...

Congratulations. I would be very interested to hear how you have done
it. And, maybe there is a chance to see it running in public?

As consequence to clicking the window closing button, TMNav calls
System.exit(int). Maybe this is an overkill when running as an applet?

Is it exactly what TMNav says? I searched the source code, but can't
find that string, neither in tmnav nor in panckoucke.

Maybe it's not comming from TMNav but from third-party code, called by
tmnav. One thing which comes to my mind is, that TMNav stores session
data with the help of java.util.prefs-package (this package uses the
notion of a node as well). I don't know how the implementations react,
when called from an applets context.

Do you have more hints?

[Tm4j-tmnav-dev] tmnav extended to applet

[Rinalldo Y. <ry...@cs...>]

Hi, I sent msgs previously regarding extending tmnav so it works on 
applet. It is now working until i clicked on the close button from the 
window (the cross shaped button). The applet closes but also closes the 
browser (which is NOT intended).

Since my teammates are supposed to access TMNav when connected to the 
server, closing the browser would then force them to re-open browser and 
log in back to the server manually.

Also, when starting TMNav, if I got msg saying "Node Removed" then TMNav 
doesnt launch, anyone know what is going on ?

thanks heaps in advance

Re: [Tm4j-tmnav-dev] running tmnav on applet

[Christoph F. <cf...@fo...>]

Hi Rinalldo,

sorry. but I have no idea. As written before, I have absolutely no
experience with applets and all I can tell you is to start googling for
applet and JFrame. I bet, you got that idea already by your own :(


Did you consider using Hypergraph (which is already an applet and is
capable to display xtm-files) or - as George did suggest - deploying
TMNav via Java Web Start. 
If you will choose the latter I would be really interested in hearing
about your experiences.

Sorry
c

Re: [Tm4j-tmnav-dev] running tmnav on applet

[Rinalldo Y. <ry...@cs...>]

Hi Christoph, thank you for your reply

Unfortunately I have tried that method before (should have told you 
earlier, sorry). I am not saying it is not working, but it still shows 
TMNav on its own window (rather than inside the applet window), however, 
the applet loads succesfully.

So the main question will be how to display a stand alone application 
window on html page (since html displays applet but since TMNav runs on it 
s own window, the TMNav window is not displayed)...

thanks heaps in advance

Re: [Tm4j-tmnav-dev] running tmnav on applet

[George T. <geo...@fr...>]

Hello Rinaldo,
Did you consider the JNLP (Java Web Start) solution?
Technicaly it is easier, and it is more suitable (I think)
Of course it depends on what you want to do.
Cheers
George

Re: [Tm4j-tmnav-dev] running tmnav on applet

[Christoph F. <cf...@fo...>]

Hi Rinalldo

You also need to call show() in TMNav. (Its not good design that this
mathod does initilisation stuff :(). 
And you probably need to comment out line 170 of TMNav where
TMNavMainFrame.show() is called.

After commented out, try this:
 
TMNav app = TMNav.getInstance();
app.show();
TMNavMainFrame frame = app.getFrame();
frame.show();

Hope that helps

Re: [Tm4j-tmnav-dev] running tmnav on applet

[Rinalldo Y. <ry...@cs...>]

Hi Christoph, thank you for your reply

Its just returning the TMNavMainFrame which is inside the TMNav.

a simple method...

in TMNav.java:

public TMNavMainFrame getFrame(){
   return frame;
}

thanks heaps in advance

Hi Rinalldo

could you send me your implementation of TMnav.getFrame()?

Re: [Tm4j-tmnav-dev] running tmnav on applet

[Rinalldo Y. <ry...@cs...>]

Hi Christoph, thank you for your reply

This is also the first time for me to convert a stand alone application 
into applet, so I am still working out the solution.

In my previous experience in using applet, basically all you have to do is 
have a frame or anything that you want to display gets constructed 
properly in the applet class. Then make the applet class "show" that 
frame. Since tmNav has a frame called TMNavMainFrame in which every panels 
and menus are included (based on my understanding of the source code), I 
assume all I have to do is create a TMNavMainFrame class variable in the 
applet class and constructs it exactly like the TMNavMainFrame is 
constructed in the tmNav.

I assumed that all I had to do was to set the TMNavMainFrame in TMNav not 
to show anything and show TMNavMainFrame which is inside the applet 
class instead, however I kept getting NullPointerException.

Even after I put additional method in TMNav class called getFrame() which 
returns TMNavMainFrame inside TMNav class, it still wouldnt work. So I 
have the following:

class myApplet extends Applet{
   TMNavMainFrame test = null;
   TMNav application = null; // must have this

   //init must be overridden
   void init(){
     //basically contains what is inside of the main function in TMNav
     //most important are:
     // application.getInstance().makeInstance();

     // application.getInstance().show();
     // if the show function is called, then TMNav runs on separate window
     // since i want the frame to be displayed in the applet, it was turned
     // off

     test = application.getInstance().getFrame();
     test.show();
   }
}

with this way, the getFrame() method is somehow returning null and hence I 
got the NullPointerException (it is supposed to return TMNavMainFrame 
inside TMNav) and since I called it after everything was constructed 
properly (that is, after the show() function is normally called in the 
main function), that I have no idea why it is returning null.

any comments ?

Re: [Tm4j-tmnav-dev] running tmnav on applet

[Christoph F. <cf...@fo...>]

Hi Rinalldo,

I've never developed an applet  so I'm just guessing, but I think that
you are on the right track. TMNav creates on startup a JFrame that is
used as its base container. 

I just had a look at the code and I think it shouldn't be too difficult
to make TMnav use a given java.awt.Container to use at its base
container. If it turns out to be fruitful, I would do a refactoring, to
enable the use of TMNav as an applet. 

Nevertheless, some questions come to my mind:

When developing an applet, are you creating the basic container by your
own, or is it provided by the enviroment (browser, appletviewer)?

What is about Menubars in applets. Are they supported?

TMnav sometimes opens new frames for some features. (TologQuery, several
dialogs). How do you deal with the concepts of opening dialogs in
applets. I think you are not allowed to open a window from an applet, or
are you? 


Hmm. I'm not really decided, whether it is possible to refactor TMNav
without extravagant expenses. What do you think?

bye
c


PS: If your sole target is to get xtm displayed as a graph in an applet,
you may have a look a Jens Kaschniks Hypergraph-Project (for kings &

[Tm4j-tmnav-dev] running tmnav on applet

[Rinalldo Y. <ry...@cs...>]

Hi, I am planning to make tmnav running on applet so I can share work on 
the server, that is, so my teammates can directly look at xtm files on the 
server using tmnav. The catch is, now tmnav runs on separate window. So 
when I viewed the applet using apppletviewer, the applet window said 
"Applet loaded" but tmnav is on its own window (which makes sense since it 
was a stand alone application anyway). Hence there are 2 windows opened.

However, when i tested it with html page, the applet did not show anything 
on the webpage. Is it possible because of the fact that tmnav runs on its 
own window and NOT on the applet window ?

anyone know how to fix this ?

thanks heaps in advance

[Tm4j-tmnav-dev] FASD project: Online survey launched

[<ben...@id...>]

Dear Open Source developer

I am doing a research project on "Fun and Software Development" in which I kindly invite you to participate.
You will find the online survey under http://fasd.ethz.ch/qsf/. The questionnaire consists of 53 questions and you will need about 15 minutes to complete it.

With the FASD project (Fun and Software Development) we want to define the motivational significance of fun when software developers decide to engage in Open Source projects. What is special about our research project is that a similar survey is planned with software developers in commercial firms. This procedure allows the immediate comparison between the involved individuals and the conditions of production of these two development models. Thus we hope to obtain substantial new insights to the phenomenon of Open Source Development.


With many thanks for your participation,
Benno Luthiger


PS:
The results of the survey will be published under http://www.isu.unizh.ch/fuehrung/blprojects/FASD/.
We have set up the mailing list fa...@we... for this study. Please see http://fasd.ethz.ch/qsf/mailinglist_en.html for registration to this mailing list.
