Hi.

I'm testing the example of the java client

ToponymSearchCriteria searchCriteria = new ToponymSearchCriteria();
searchCriteria.setQ("zurich");
ToponymSearchResult searchResult = WebService.search(searchCriteria);
for (Toponym toponym : searchResult.toponyms) {
System.out.println(toponym.getName()+" "+ toponym.getCountryName());
}

And i get this error:
[cor=red]
java.lang.UnsupportedClassVersionError: Bad version number in .class file

Which can be the problem?

Hi

The jar has been compiled with java6. You are likely to use an older java version. We have added another jar compiled for java5: http://www.geonames.org/source-code/
This will solve your problem if you are using java5.
