Dear Jesse and Jody,
my castor librairy is not added to the JRE but is already embedded
in my plugin. A xerces librairy is also embedded in my plugin. But
when my classes (ServiceExtension) are loaded through another plugin
(CatalogPlugin I suppose), the castor lib is found (the stacktrace
shows castor calls) but the xerces lib is the one from the JRE.
I'll try to find documentation on how ClassLoaders work in Eclipse.
If you have the solution or if you have an idea to test, let me know.
As I already embed jars in my plugin, I suppose creating a plugin
that provides xerces and castor as suggested by Jody will have no
effect. Right ?
Thanks guys
Vincent

This is a rather difficult issue. I would first say that the
Castor jars shouldn't be added to the JRE rather they should be
included in your jar so they don't interfere with the other
plugins. In particular the plugins that load the maps. Also make
sure you fully qualify which xml files you are using...
Other than that I'm not sure what to do off the top of my head.

Dear all,
I have the following problem.
I created a new data type from XML content.
When I run uDig for the time in a clean workspace, everything
works well. I can create services that are displayed in the
localcatalog view.
When I close and try to run uDig once again, previously loaded
services are loaded through the ServiceExtension extension. It
seems that the XML parser used to load my service is the one from
the JDK, not the xerces librairy I included in my plugin, not the
xerces version included in the lib plugin.
As I use Castor for XML mapping, I get an exception when reading
XML content.
I really believe it is a problem of classloader but I don't know
what to do?
Any Idea ?
I already encountered a similar problem when embedding Jetty in
uDig, I worked very well on first run but never again. I did not
resolve this bug. This new problem let me say that it could be a
problem with xml parsers as Jetty also uses XML for its
configuration.
Thanks for your help
Vincent.
PS: I did not forget my previous questions (one week ago) to
display layers in a heriarchical manner, but I tried to diplay
them first in a flat way. Can the members method on IGeoResource
help me ?
