Hey guys,
I had to fix what I believe to be a bug in the WFS client to get it
working under OSGI (Apache Felix), and I wanted to share what I found
...
I had to change the way that
org.geotools.data.wfs.protocol.wfs.WFSExtensions looks up the
WFSResponseParserFactory service. Currently, the code is going straight
to the javax.imageio.spi.ServiceRegistry. Looking around the code,
however, it seemed that other places were using the
org.geotools.factory.FactoryCreator class, which is a bit more clever
when it comes to mulit-classloader environments (such as OSGI). I
modified the core logic into the getServiceProviders method to the
following:
FactoryRegistry factReg = new FactoryCreator( new
Class[]{WFSResponseParserFactory.class});
factReg.scanForPlugins();
Iterator<WFSResponseParserFactory> providers =
factReg.getServiceProviders(WFSResponseParserFactory.class, true);
registry = new HashSet<WFSResponseParserFactory>();
while (providers.hasNext()) {
WFSResponseParserFactory provider =
providers.next();
registry.add(provider);
}
This seems to solve the problem. If you folks are happy with this
solution, I can create an issue and attach the new file (or a diff).
One other question with regards to the WFS library - in the code it's
under a module called "unsupported", but I don't seem to see anything on
the wiki regarding this module as unsupported. Is this in fact an
unsupported module? And if so, what does that mean exactly?
Thanks,
Nathan Mittler
