The code sequence causing the error is
try {
Class providerClass = Class.forName(providerClassName);
GeneralizationInfosProvider provider =
(GeneralizationInfosProvider) providerClass
.newInstance();
GeneralizationInfos gInfos =
provider.getGeneralizationInfos(providerParam);
Class repositoryClass = Class.forName(repositoryClassName);
Repository repository = (Repository)
repositoryClass.newInstance();
return new PreGeneralizedDataStore(gInfos, repository, namespace);
} catch (Exception ex) {
throw new IOException(ex.getMessage());
}
Unfortunately, java 1.5 does not have a constructor
IOException(Exception ex), so we see no stack strace from the
interesting exception ex. Please check the following.
cd <geoserver install dir>/WEB-INF/lib
Here you should find two jar files
feature-pregeneralized-*.jar
gt-feature-pregeneralized-*.jar
Use a zip or jar utility to list the content of the first. You should
see an entry
org/geoserver/data/gen/info/GeneralizationInfosProviderImpl.class
The same holds true for the second class you entered in the admin GUI.
If both classes are in the class path, the error occurs reading the
xml file. What exactly do you enter for the xml config file param ?.
