R: [TM4J-users] typing topics

[Andrea C. <mai...@st...>]

Hi Kal, hi Stefan
I'm not using TMAPI, so, unfortunately, I couldn't make use of the
XTMSerializer. Anyway, I modified the XTMWriter, just as Kal proposed, and
it worked! This helped me very much in my work. Thank you very much!
By the way, I think it would be very useful if the possibility to use
subjectIndicatorRef where possible were implemented in the next versions of
TM4J, just like Kal wrote.

Thanks again!
Andrea

Oggetto: Re: [TM4J-users] typing topics

Hi Andrea,

There is already an implementation of the solution Kal proposed. I dunno 
if you use the TMAPI Interfaces TM4J provides, but there is a project 
called tmapi-utils[1] out there which contains an XTMSerializer, which 
can be switched to do exactly that what kal proposes (using 
subjectIndicatorRef instead of topicRef, if the typing topic has a 
subject indicator).

Therfore you just have to call 
XTMSerializer.setProperty("org.tmapi-utils.impexp.xtm.XTMSerializer.subjectI
dentifiersOnly",true);

feel free to contact me

Re: [TM4J-users] typing topics

[Kal A. <ka...@te...>]

Hi Andrea,

When TM4J exports a topic map, all subjectIndicatorRef references to 
topics are converted into topicRef references - this is just the default 
behaviour of the XTM export code.

Right now there is no option to use subjectIndicatorRef where possible, 
but that could be added as a new feature. To implement it for yourself, 
you will need to override the behaviour in XTMWriter. Take a look at the 
method topicRef (about line 665) - this is invoked from various places 
in the XTMWriter code to write a <topicRef> element. You could modify 
this method to check if the the Topic in the parameter t has a subject 
indicator and if it does, call the ref() method to write a subject 
indicator ref (there is an example of this on line 678.

The important thing to note here is that even though TM4J's default 
behaviour is to "normalise" all references into topicRef references, the 
subject indicators in the original merged topic maps are preserved. 
Also, although the ID attribute values may get changed (especially when 
you merge topic maps), the original IDs are also preserved as full URLs 
in the sourceLocators property.

Hope this helps!

[TM4J-users] typing topics

[Andrea C. <mai...@st...>]

Hi All, 
I have the following small problem, and I can't find an answer to it in the
programmer's guide: when I export a topic map to an XTM file, I see that in
the file the typing-topics of a certain topic are indicated in it by means
of their IDs. If the topic map is the result of a merge of several topic
maps, this causes problems, because many IDs of merged topics are
overwritten! 
I'd like to make use of the subject indicators of the typing topics (instead
of the IDs) in order to indicate the type of a topic. Is it possible? How
does it work?
Thanks!
Andrea
 

[TM4J-users] MergedTopicSubjectClashException

[Richard G. <ric...@ya...>]

Hi All,

I'm getting a TopicMapRuntimeException, ultimately caused by a MergedTopicSubjectClashException,
when I try to load a topic map into a particular topic map into a provide. A portion of the stack
track is below.

TopicMapProviderException. Caused by: . Cause: org.tm4j.topicmap.TopicMapProcessingException: 
Cause: org.tm4j.topicmap.TopicMapRuntimeException: 
Cause: org.tm4j.topicmap.MergedTopicSubjectClashException: Attempted to merge two topics with
different subjects,
Cause:Attempted to merge two topics with different subjects,
	at org.tm4j.topicmap.source.TopicMapSourceSupport.addTopicMap(TopicMapSourceSupport.java:37)
	at org.tm4j.topicmap.source.TopicMapSourceSupport.addTopicMap(TopicMapSourceSupport.java:69)
	at mips.genre.topicmaps.AddTopicMap.addToMemory(AddTopicMap.java:126)
	at mips.genre.topicmaps.AddTopicMap.main(AddTopicMap.java:57)

I want to use the MergedTopicSubjectClashException.getTopics() method to find out the causing of
the problem, so I have the following catch block:

catch(Exception e) {
			if (e.getCause().getCause().getCause() instanceof MergedTopicSubjectClashException) {
				Topic clashTopics[] = new Topic[2];
				((MergedTopicSubjectClashException)
e.getCause().getCause().getCause()).getTopics(clashTopics);			
				for (int i=0; i<clashTopics.length; i++) {
					Topic ct = clashTopics[i];
					System.out.println(ct.getID());
					Iterator nameIt = ct.getNames().iterator();
					while(nameIt.hasNext())
					{
						BaseName name = (BaseName)nameIt.next();	
					    System.out.println(name.getData());				
					}
					Iterator locIt = ct.getNames().iterator();
					while(locIt.hasNext())
					{
						URILocator loc = (URILocator)locIt.next();				
					    System.out.println(loc.getAddress());				
					}					
				}				
				e.printStackTrace();
			}
			else {
				e.printStackTrace();
			}	
		}

But, it looks like the getTopics() method isn't returning anything, as I get a
NullPointerException generated by the line: 

System.out.println(ct.getID());

This may just be something I'm doing wrong, so if anyone can point me in the right direction I'd
be grateful.

Cheers,

Richard.

Hi Minh,

The stylesheets are part of the TM4Web/Cocoon integration which is not 
currently available as a download package - you have to grab them from 
CVS. The module that you need to check out is named tm4web.

[TM4J-users] Would like advice on integrating TMNAV hypergraph & my TM4J-based app

[Bret C. <bre...@ya...>]

Hi Christoph,

A while back we had an exchange about developing a new
abstractor. I still haven't gotten to this task, but I
would like to focus on the intermediate task of
integrating the existing Hypergraph in TMNAV with my
TM4J-based application, with its data-entry windows
for entering data into a topic map. Any advice you
have would be appreciated.

I have attached a letter with more on what I need.

I also want to let you know that I downloaded tmnav
0.2.9pre1-src, and had the same problem as with 0.2.8
of not being able to run the app until I manually
copied the *.xml configuration files into the .tmnav
directory.

[TM4J-users] Using Tolog's value-like-predicate in TM4Web?

[Mathias R. <mat...@we...>]

Hello,

I'm trying to use Tolog's value-like-predicate in a

I get the error below. How can I register the required
full-text index? Can I do this in the velocity layer

[TM4J-users] Deleting a "Topic type"

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

Hello Kal,

While I try to delete a Topic that plays a "Role" in an Association or it is
"Occurrence Type",
the deletion does not completed and I get an Exception that descibes the
problem.

From the other hand when the Topic is a "Topic Type" of another topic,
I get not such Exception, the deletion fulfiled, and
there are some problems with the other Topic (I thing).

Is this a bug and should I wait to be fixed?
or should I handle the case in my program differently?

Thank you
George

I think there is a way around, a little trick that is commonly used in 
topic map engines,
just add a sourcelocator of the form [xml:base]#[id] to the object. for 
your example
you have to add "c:\xyz\123.xtm#thisid" to set "thisid" for some topic 
or other topicmap object.

hope that helps.

[TM4J-users] about ID(s)

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

Hello Kal

On opening XTM files with TM4J, it seems to me that the
"Topic Map id" that is registered in the XTM is ignored.
instead the TM4J creates a new id for the "Topic Map"

<topicMap id="abc"
    xml:base="c:\xyz\123.xtm"
    xmlns="http://www.topicmaps.org/xtm/1.0/"
    xmlns:xlink="http://www.w3.org/1999/xlink">
</topicMap>

instead of "abc" it gives to me something like "x1k75974ts-0"
is this in purpose?


Also I would like to be able to change some id(s) from already registered
"Topics".
Are you thinking to include this "id change" in the future?

Thank you
George

[TM4J-users] Problem re-running a prepared, paramatized, query with a new parameter

[Bret C. <bre...@ya...>]

Kal,

Here's somthing that looks like a TM4J bug to me.
(I'm using tm4j-src-0.9.6):

I execute a (one-parameter) paramatized prepared
query, passing it parameter A.
I get the correct result set for having passed A.

I re-execute the prepared query, this time passing it
parameter B.
I get the result set I got when I passed A, not what I
should get passing B.

I re-prepare the query, and then pass it the parameter
B. This time, I get the correct result.

I don't know if the bug is on Kal's side or mine. I
can't seem to find it on my side,
though of course it could still be there.

(I've already embedded into my app. the call to
re-prepare each prepared query before re-executing it,
a temporary work-around - and good enough  my purposes
for now.)

Bret

This is the state of the topicmap reference immediately after you
received it from your call to StoreManager.loadTopicmap(...)

Panckoucke loads topicmaps asynchroniously.
StoreManager.loadTopicmap(...) puts your demand to load a topicmap into
a queue from which it is fetched and processed somewhere in the future.
While beeing processed (being loaded, merged, closed), the topicmap
reference runs through several states. Switching from one state to the
next triggers a TM_STATE_CHANGED event. 
A panckoucke NotificationListener can catch this event and react as
appropriate. In the ExampleOpenTopicmap-Class catching a
TM_STATE_CHANGE-Event leads to some system-outs.

The state changed from opening to accessible, which means that it is now
legal to access the topicmap through this topicmap reference. If tm4j
would have failed for any reason to load the topicmap the state would
have changed to "corrupt"

This is a listing of all topics that are part of the previously loaded 
topicmap.
It is produced by the example Abstractor/Renderer-Code. Strictly
speaking, this is not related to open topicmaps but to "how does the
abstraction / renderer process works"

Re: [TM4J-users] can not find org.tm4j.panckoucke.* library

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

Hi Grace

you need to add panckoucke-0.3.1.jar to your classpath.
The jar is located in the base-directory of the binary distribution 


Hope that helps

Re: [TM4J-users] TM4Web: factory.props missing

[Jonas G. <gr...@gm...>]

Hi Kal,

I tried upgrading to 0.9.7, which sort of eliminitated the issue and raised
a new one at the same time - the very same issue that Christoph Fr=F6hlich
describes in his Oct. 11 post.

But after having replaced my batch.xml with version 1.3 and added
toolbox.xml as you describe, everything works perfectly. I'm very happy wit=
h
that.

You need to create the filename object. You can do this by adding the
following line to topicmap.vm:

#set ($filename  =
$factory.create("org.tm4j.vtl.extractors.FileNameExtractor"))

The factory variable should be initialised by the toolbox.xml. Actually
it probably makes sense for FileNameExtractor to implement the Velocity
ViewTool interface so that you can load it in the toolbox.xml. But for
now, add that line to topicmap.vm as a workaround.

> I haven't got deep enough into tm4Web to know where I should start to

> 
In general, any variables set by #set in topicmap.vm or setup.vm are
available when processing the whole topic map. Any variables set in
topic.vm or any of the templates it calls are available only for the
processing of that topic.

The toolbox.xml allows you to choose the scope of a variable. If the
<scope> element content is  "request" then the tool is initialised once
for each page generated. If the <scope> element content is application
then the tool is initialised once at the start of processing and the
same instance is available to every page.

Hope this helps!

Re: [TM4J-users] NullPointer in TM4JVelocityApp.pushContext

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

Hi Kal

thanks for the quick fix. It works now...  until I reach

org.tm4j.topicmap.utils.extractors.AssociationGroupsExtractor$DefaultAssociationGroupComparator.compare(AssociationGroupsExtractor.java:149)

where another NullPointer waits. I fixed this one myself and could
either commit the fix or send you a patch, just as you prefer.

Beside of this last NPE, batch.xml now runs successfully and produces a
lot of html files.

Unfortunately there is one more problem with the default skin.
The "topicref"-macro in "utils.vm" constantly produces the following
loglines: 
Mon Oct 11 19:39:11 CEST 2004   [warn]
org.apache.velocity.runtime.exception.ReferenceException: reference :
template = associations.vm [line 2,column 29] : ${filename.fn($topic)}
is not a valid reference.

Therefor all links from index.html to any topic detail page refer to the
unresolved string "$filename.fn($topic).html".

I haven't got deep enough into tm4Web to know where I should start to
look for the missing reference. Do you have a hint for me?

Thanks

Re: [TM4J-users] NullPointer in TM4JVelocityApp.pushContext

Hi Cristoph,

Thanks for the bug report. 

The only problem is the missing -t option on the command line. I've
updated batch.xml and added a toolbox.xml that is safe for batch HTML
generation into CVS.

[TM4J-users] NullPointer in TM4JVelocityApp.pushContext

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

Hi Kal

when executing

  ant -f batch.xml -Dtopicmap=tmworld.xtm topicmap

I'm getting the following null pointer

     [copy] Copying 1 file to /opt/java/tm4web/build/batch/temp
     [java] 0    [main] WARN  org.tm4j.vtl.factory.BaseFactory  - Could not locate properties file: factory.props
     [java] Cannot find CatalogManager.properties
     [java] Processing explicit mergeMap directives...
     [java] Merging referenced topic maps...
     [java] All external maps merged!
     [java] Making merged map consistent...
     [java] Consistency processing complete!
     [java] java.lang.NullPointerException
     [java]     at org.tm4j.vtl.TM4JVelocityApp.pushContext(TM4JVelocityApp.java:429)
     [java]     at org.tm4j.vtl.TM4JVelocityApp.startTopicMap(TM4JVelocityApp.java:401)

     [java]     at org.tm4j.vtl.TM4JVelocityApp.main(TM4JVelocityApp.java:223)


This happens with both, tm4web/velocity0.2rc1 and the current cvs-checkout. 
I'm using tm4j 0.9.7

Tracing the source it seems obvious that m_toolboxManager is not initialized 
because batch.xml does not specify the toolbox option on the command line.

do I miss something? 

Thanks

Re: [TM4J-users] TM4Web: factory.props missing

[Kal A. <ka...@te...>]

Hi Jonas,

Actually I think that the stack overflow is probably not a problem with
TM4Web but with TM4J. I found a couple of these issues with 0.9.6 which
I have fixed for the 0.9.7 release (just uploaded to sourceforge in the
last ten minutes!). TM4Web should work fine with this new version of the
core library. Can you try replacing your TM4J 0.9.6 JARs with the TM4J
0.9.7 JARs and then rerun the process. If you still get a faliure, can
you send me the XTM file that causes the problem so that I can track
down where the stack overflow occurs ?

As for the missing factory.props file, there isn't a default
factory.props shipped with TM4Web, because all the default settings in
the code are fine. Perhaps there should be a default factory.props to
serve as a template for writing your own file. I'm going to log this as
a bug to fix for the next TM4Web release.

Cheers,

Kal
