Opensocial service SOAP

[13年前 に Cesar William によって更新されました。]

I modified the opensocial portlet to expose the service via a SOAP service. When I was using liferay 6.0.2 consumption of the web service was working fine, but when I moved to liferay 6.0.3 when I try to run a service it returns:
<faultstring> java.lang.ClassCastException: org.apache.xerces.parsers.XIncludeAwareParserConfiguration can not be cast to org.apache.xerces.xni.parser.XMLParserConfiguration </ faultstring>

Why?
I've tried to remove the libraries xerces and xml-apis but continued with the same error.
What can I do?

/**
 * <p>
 * This class provides a SOAP utility for the
 * {@link com.liferay.opensocial.service.GadgetServiceUtil} service utility. The
 * static methods of this class calls the same methods of the service utility.
 * However, the signatures are different because it is difficult for SOAP to
 * support certain types.
 * </p>
 *
 * <p>
 * ServiceBuilder follows certain rules in translating the methods. For example,
 * if the method in the service utility returns a {@link java.util.List}, that
 * is translated to an array of {@link com.liferay.opensocial.model.GadgetSoap}.
 * If the method in the service utility returns a
 * {@link com.liferay.opensocial.model.Gadget}, that is translated to a
 * {@link com.liferay.opensocial.model.GadgetSoap}. Methods that SOAP cannot
 * safely wire are skipped.
 * </p>
 *
 * <p>
 * The benefits of using the SOAP utility is that it is cross platform
 * compatible. SOAP allows different languages like Java, .NET, C++, PHP, and
 * even Perl, to call the generated services. One drawback of SOAP is that it is
 * slow because it needs to serialize all calls into a text format (XML).
 * </p>
 *
 * <p>
 * You can see a list of services at
 * http://localhost:8080/tunnel-web/secure/axis. Set the property
 * <b>tunnel.servlet.hosts.allowed</b> in portal.properties to configure
 * security.
 * </p>
 *
 * <p>
 * The SOAP utility is only generated for remote services.

public class GadgetServiceSoap {
private static Log _log = LogFactoryUtil.getLog(GadgetServiceSoap.class);
	
	public static String addGadget(long companyId, java.lang.String name, java.lang.String url){
		
		try{
			GadgetLocalServiceUtil.addGadget(companyId, name, url);
		} catch(Exception e){
			_log.error(e, e);
			System.out.println("AddGaget Error: " + e.getMessage());
		}
		return "Gadget added";
	}
}

I created it with:
# ant build-service
# ant build-wsdd
# ant clean deploy

What's wrong?
