Hi,
I am trying to perform a copy from a TopicMap generated from in memory
provider and populate my topicmap stored in the database.
While copying the scope bounded basenames, the copy operations errors out
with a class cast exception...
TopicMap:
topicmaps/kings_and_queens.xtm # Sample provided in the examples
Code Snippet:
TopicMapProvider provider_m = tmpf_m.newTopicMapProvider(providerProps);
Locator baseLocator_m = provider_m.getLocatorFactory().createLocator("URI",
getInputURI());
TopicMapSource src_m = new SerializedTopicMapSource(getInputStream(),
baseLocator_m);
// Parse the topic map
TopicMap tm_m = provider_m.addTopicMap(src_m);
TopicMapProvider provider_h = tmpf_h.newTopicMapProvider(providerProps);
Locator baseLocator_h = provider_h.getLocatorFactory().createLocator("URI",
getInputURI());
TopicMap tm_h = provider_h.getTopicMap(baseLocator_h);
provider_h.removeTopicMap(tm_h);
tm_h = provider_h.createTopicMap(baseLocator_h);
// Perform a copy
tm_h.getFactory().copy(tm_m);
Stack trace:
Exception in thread "main" org.tm4j.topicmap.TopicMapRuntimeException:

Am I missing anything here...
Any help would me much appreciated!!!

hi,
Topic:
Copy of contents xtm files to my-sql DBMS.
The process goes smooth till it finds scope object in either <basename(s)>
or <occurrence(s)>
If observed, in the method copyScopedObject of
TopicMapFactoryBase.TopicMapFactoryBase, the Topic object is sent as is to
the implementation classes, which works fine if the copy is performed at the
same level (file-system to file-system).
Have tried fixing this problem and did a bit of testing too, to copy the
topics from various XTM, provided in the example section.
If there is a process I would have to follow in order to test the validity
of my logic, please let me know.
Thank you.

I applied your patch to both the "MAIN" and the "TM4J_1_x" branch of TM4J. > > If there is a process I would have to follow in order to test the > validity of my logic, please let me know. I wish TM4J had a comprehensive test suite that could be applied before checking in a patch, but (apart from "ant ozone-test", which is not really a test suite), I'm not aware of any test suite for TM4J. Using the mailing-list is okay (for me), but maybe raising a bug at https://sourceforge.net/tracker/?group_id=27895&atid=391879 would make the discussion more standardized. :-) > > Thank you.
