Hi all,

So.. when I search about PredicadoSemantico($T) the answer should be =
all associations that are subclass too.
If is impossible, how can I to do this if I don't know all =
PredicadoSemantico (fundamenta, pre requisito, ... )
Thanks,
Adriana.

The current TM4J tolog implementation uses the TM4J native model (but you can use the tolog implementation with topic maps created with TMAPI). http://tm4j.org/docs/devguide/ch08.html#N11776 Note, that the tolog implementation is not feature complete, you cannot use all contructs described in the Ontopia Tolog guide.

Hello all,
In my effort to migrate TM4L to using TMAPI (which I recently renewed
:-) I got to a problem in using the getScope() method of Variant. When
I try=20
Collection vc =3D bn.getVariants();
Iterator it =3D vc.iterator();
while (it.hasNext()) {
Variant var =3D (Variant) it.next();
Iterator si =3D
var.getScope().iterator();=09
if (si.hasNext()){
Topic param =3D (Topic)si.next();
//***Exception Here****
I get: JavaLangClassCastException: Org.TM4J.TopicMap.Memory.TopicMapImpl
It looks like the unmodifiable result set of var.getScope() is a set of
TM4J topics and there is no way to cast them to TMAPI topics.
Any ideas of how to solve this problem?
Thanks,
Darina

Are you sure that your "Variant" is a "org.tmapi.core.Variant" and not
a "org.tm4j.topicmap.Variant"? I've the suspicion that you mix up the
classes from TM4J and TMAPI by mistake.
The name bound to "bn" must be an instance of type
"org.tmapi.core.TopicName". If it is an instance of
"org.tm4j.topicmap.BaseName", your iterator returns variants of type
"org.tm4j.topicmap.Variant" and these instances return objects of type
"org.tm4j.topicmap.Topic" if you call "getScope()".
Please check if you're working with the TMAPI interfaces only.
If you need to work with TM4J interfaces *and* TMAPI interfaces, the
class "org.tm4j.tmapi.helpers.Wrapper" may help you to 'wrap' and
'unwrap' objects into both directions.
Best regards,
Lars

Well, the variant is TMAPI Variant - here is the value of "var" above:
org.tm4j.tmapi.core.TMAPIVariantImpl@75327fd8
The name is also an TMAPI name:=20
I divided Iterator si =3D var.getScope().iterator(); into
Set s =3D var.getScope();
Iterator si =3D s.iterator();
So, now the picture is:
Collection vc =3D bn.getVariants();
Iterator it =3D vc.iterator();
while (it.hasNext()) {
Variant var =3D (Variant) it.next();
Set s =3D var.getScope();
Iterator si =3D s.iterator(); =20
if (si.hasNext()){
Topic param =3D (Topic)si.next(); //***Exception Here****
=20
and just before the exception I have:
var: org.tm4j.tmapi.core.TMAPIVariantImpl@75327fd8
but in the Set s: HashMap -> Table -> HashMap$Entry -> key [4] =3D
org.tm4j.topicmap.memory.TopicImpl@d00f8c41
and the imports are:
import java.util.Collection;
import java.util.HashSet;
import java.util.Iterator;
import java.util.Set;
import org.tmapi.core.Locator;
import org.tmapi.core.Topic;
import org.tmapi.core.TopicMap;
import org.tmapi.core.TopicName;
import org.tmapi.core.Variant;
import org.tmapi.index.core.TopicNamesIndex;
So, I am not using TM4J directly, only TMAPI. Which means that the TMAPI
getScope() applied on the TMAPI variant var returns an unmodifiable set
of TM4J topics and that is why I am getting the cast exception.

I don't really want to work with both interfaces, so I only use the
TMAPI interface.
Any further idea?=20

Hi Darina, [...] > Well, the variant is TMAPI Variant - here is the value of "var" above: > org.tm4j.tmapi.core.TMAPIVariantImpl@75327fd8 That's strange. I found a bug in the Wrapper class (fixed in the CVS), but it was not related to the variant handling of TM4J. Which TM4J version are you using? Please use the CVS version, the official release is outdated. I've created a simple test case (attached) and everything works as expected, no exceptions. Please check, if the test case works with your TM4J installation. Best regards, Lars -- http://www.semagia.com http://www.topicmaps.de/mailinglist German Topic Maps mailinglist |

I think, you're using an 'old' version of TM4J.
While walking through the bug tracker, I've found this bug report here:
<https://sourceforge.net/tracker/index.php?func=detail&aid=1433778&group_id=27895&atid=391879>
This is exactly the same issue.
It was fixed in Feb/2006.

Hi Lars,
I downloaded the latest version of TM4J 0.9.8 from CVS, but now I have a
different problem that reminds me though the problem I had in the very
beginning of swiching to TMAPI and which was due to using differrent
versions of TM4J in the complilion of TM4L anf TMAPI (see below).=20
After downloading TM4J, I created a binary which resulted in creating 6
jar files which I copied in the lib folder of my Eclipse TM4L project (I
also deleted the 0.9.7 versions of those files from lib):
tm4j-0.9.8.jar
tm4jadmintool-0.9.8.jar
tm4jdbc-0.9.8.jar
tm4j-tmapi-0.9.8.jar
tm4j-tologx-0.9.8.jar
tm4ozone-0.9.8.jar=20
I am not sure was I supposed to do anything else?=20
Thanks,
Darina

Well, the CVS version isn't 0.9.8. It's newer. Do not use the binary
downloads from TMJ, use the source. :)
If you compile the source in from the CVS, you should get Jars in this form:
tm4j-<builddate>.jar
So, if you compile TM4J from source today, you'll get
tm4j-20070215.jar
tm4j-tmapi-20070215.jar

You need some additional libs in your build path. The error says, that
the Apache Commons Collections lib is missing.
The missing libs are located in the "tm4j/lib" folder (also in the
CVS). You don't need all of them, but you add all of them into the
build path if you want to be on the save side. :)
Please note, that TM4J uses an old TMAPI release, you should use the
TMAPI 1.0 SP1 release (you can find the release here:
<http://sf.net/projects/tmapi/>) and remove the "tmapi-1_0.jar" the
build path.
Best regards,
Lars

Hello,
Can someone help?
I am trying to set a Hibernate backend for TM4L but don't understand the
concept of baseLocator for a topic map stored in a database. For
example, what should be given in the create statement below, if
"hibernate.connection.url" has a value of "jdbc:mysql://localhost/tm4l"=20
=09
createTopicMap(java.lang.String baseLocatorReference, java.lang.String
baseLocatorNotation)
Creates a new topic map with a specified base locator.
Many thanks,
Darina

Hi Darina,
Please start a new thread for new topics and don't use the old "tolog"
thread (from June 2006!) to post new questions. Thank you in advance.
:)
I assume, you're using the RDBMS backend through TMAPI?
I've to admit that I never tried such a combination.

You can use any locator you like. It has nothing to do with the
database URI. The base locator is just the URI of the topic map (the
'storage address', if you like). If you say
tm = tmSys.reateTopicMap("http://www.example.org/my-tm");
A new topic map with the base locator "http://www.example.org/my-tm"
is created.
I assume, that you have to provide the connection URI via
TopicMapSystemFactory tmSysFac = TopicMapSystemFactory.newInstance();
tmSysFac.setProperty("property-name", "property-value")
TopicMapSystem tmSys = tmSysFac.newTopicMapSystem();

Hello all,
I have a problem in using the removeSubjectLocator(l) method - it just
doesn't work for me ...
I am copying a method to replace a subject locator of a topic with a new
one - have no idea what I am doing wrong...
Any help is highly appreciated.
Thanks,
Darina
---------------
public static void replaceOldSubjectLocator(Topic t,
String oldSubjectLocator, String newSubjectLocator, TopicMap tm)
throws Exception {
Collection sic = t.getSubjectLocators();
if (!sic.isEmpty()) {
Iterator it = sic.iterator();
while (it.hasNext()) {
Locator l = (Locator) it.next();
if (oldSubjectLocator.equals(l.getReference()))
{
t.removeSubjectLocator(l);
}
}
}
if (!newSubjectLocator.equals("")) {
Locator siLoc = tm.createLocator(newSubjectLocator,
"URI");
t.addSubjectLocator(siLoc);
}
}

Possible problem: I believe that TM4J manages max. one subject locator
(since XTM 1.0 allows just one). So, if you have a topic with subject
locator "A" and you call your function with
replaceOldSubjectLocator(t, "B", "C");
the existing subject locator ("A") would not have been matched with
"B" and if you add "C", the locator "A" goes away since TM4J handles
just one locator. (I am not sure if TM4J overrides any existing
subject locator silently).
Maybe you can drop in [tinyTiM] (for testing purposes) as TMAPI
implementation and see if you get the expected results. tinyTiM
handles 0..n subject locators and is more TMAPI compatible than TM4J.

Hi Lars,
Thanks a lot for replying.

Well, it just doesn't remove the subject locator: When I do:
System.out.println("oldSubjectLocator: "+oldSubjectLocator);
System.out.println("newSubjectLocator: "+newSubjectLocator);
if (!oldSubjectLocator.equals("")) {
Locator l = (Locator)t.getSubjectLocators().iterator().next();
System.out.println("loc 1: "+l.getReference());
System.out.println("loc 1: "+l.getNotation());
System.out.println("loc 1: "+l.toString());
t.removeSubjectLocator(l);
Locator l2 = (Locator)t.getSubjectLocators().iterator().next();
System.out.println("loc 2: "+l2.getReference());
System.out.println("loc 2: "+l2.getNotation());
System.out.println("loc 2: "+l.toString());
}
I get:
[java] oldSubjectLocator:
c:\\workspace\\TM4L_Plugins\\plugins\\XSLT\\out.xtm
[java] newSubjectLocator:
c:\\workspace\\TM4L_Plugins\\plugins\\XSLT\\out22.xtm
[java] loc 1: c:\\workspace\\TM4L_Plugins\\plugins\\XSLT\\out.xtm
[java] loc 1: URI
[java] loc 1: org.tm4j.tmapi.core.TMAPILocatorImpl@1048d930
[java] loc 2: c:\\workspace\\TM4L_Plugins\\plugins\\XSLT\\out.xtm
[java] loc 2: URI
[java] loc 2: org.tm4j.tmapi.core.TMAPILocatorImpl@1048d930
obviously, the locator doesn't get removed, i.e.
t.removeSubjectLocator(l); doesn't work ... And of course when after
that I try to add the new subject locator, I get the error message that
XTM1.0 doesn't allow more than 1 subject locator.

Well, as you can see above, the locators "A" and "B" are the same ...

Thank you, however, if even I get it working there, this will not solve
my problem in TM4L ...
Any other idea that I can try?
I really appreciate your effort to help.

Seems to be a bug in the TMAPI impl: <http://tm4j.cvs.sourceforge.net/tm4j/tm4j/src/org/tm4j/tmapi/core/TMAPITopicImpl.java?revision=1.23&view=markup> 332 if (rawLoc.equals(m_obj.getSubject())) { 333 return; 334 } If the locator to be removed is equals to the current locator, that method returns. Strange. Correct impl: if (!rawLoc.equals(m_obj.getSubject())) { return; } If the locator IS NOT equal to the current locator, the method should do nothing. I'll try to commit the bug fix. I'll use the "TM4J_1_x" branch. So, you'll have to check out the "TM4J_1_x" branch and compile everything (at least the TMAPI stuff). Best regards, Lars -- Semagia <http://www.semagia.com> |

Hi Lars, Many thanks for this. I checked out the corrected class (TMAPITopicImpl.java) and recompiled TM4J to get new jars, however, had a problem - I forgot that I had done some changes beforehand since TMAPI doesn't support TOLOG. So, TM4L cannot currently compile :-( Anyway, my question is, what is the smallest part containing the change that I can compile independently in a jar and add it to the other TM4J/TMAPI jars?

Search for "removeSubjectLocator" in your TMAPITopicImpl and change the
the following lines from:
if (rawLoc.equals(m_obj.getSubject())) {
return;
}
into
if (!rawLoc.equals(m_obj.getSubject())) {
return;
}
Just add a ! in front to the rawLoc.
In the original TMAPITopicImpl file that code appears in the lines
332 - 334.
Best regards,
Lars
